What Is a Lazy Eye?
A lazy eye is medically known as amblyopia. It is a type of reduced vision that occurs in one eye. The condition is called a lazy eye because the stronger eye works best.
Amblyopia is the most common cause of visual impairment in children. The eye condition usually occurs between birth and seven years of age. Amblyopia is more frequent in small or premature babies. It is also more likely to develop in children with a family history of amblyopia.
It can be challenging to diagnose a lazy eye. Often, amblyopia is detected during a routine eye exam.
If left untreated, a lazy eye can result in permanent vision loss in the affected eye. If your child shows any symptoms or side effects of amblyopia, take them to an eye doctor. For example, the eyes may appear as if they don’t ‘work together.’
Why Does Lazy Eye Develop?
Amblyopia occurs when the eye develops abnormally in early childhood. The weak eye tends to wander inwards or outwards.
A lazy eye develops when there’s a breakdown in how the brain and the weak eye work together. The brain won’t recognize the sight from one eye. In time, the brain relies more and more on the strong eye. Simultaneously, the weak eye’s vision worsens.
In most cases, doctors don’t understand the direct cause of amblyopia. However, sometimes different vision problems may lead to amblyopia.
Usually, the brain uses nerve signals from both eyes to see. If an eye condition worsens the vision in one eye, the brain may try to work around it. The brain may switch off signals from the weaker eye, favoring the good eye.
Some eye conditions that can develop amblyopia include:
How to Get Rid of a Lazy Eye
If there are any vision problems causing amblyopia, an eye doctor may treat that first. The treatment options for amblyopia depend on several factors, such as how severe the condition is.
Surgical Lazy Eye Treatments
In children, cataracts may be removed during eye surgery to treat a lazy eye. This allows for better development of vision in the weak eye. Cataract surgery for young and older children is carried out under general anesthesia.
Cataract surgery usually takes one to two hours. Your child may stay in the hospital overnight so the staff can check their recovery. Patients must use eye drops afterward.
Eye Muscle Surgery
The operation changes the position of the lazy eye by either strengthening or weakening its eye muscles.
As a result, the lazy eye appears better aligned with the strong eye. Eye muscle surgery doesn’t improve the patient’s vision, but their eyes will look straighter. It also helps the eyes function better together.
Non-Surgical Lazy Eye Treatments
Glasses can correct existing refractive errors in childrens’ eyes. Refractive errors include nearsightedness, farsightedness, and astigmatism. In children with amblyopia, one eye is often more nearsighted or farsighted than the other.
By wearing eyeglasses, the other vision problem is treated. For some patients, wearing glasses is enough to fix amblyopia. However, many children may also need further treatment to treat an amblyopic eye effectively.
The treatment of amblyopia may include vision therapy techniques, such as occlusion therapy. Occlusion therapy for a lazy eye involves wearing an eye patch. The patch covers the better eye for several hours a day.
For children wearing glasses, the lens over the stronger eye can be covered. This treatment prompts the weaker eye to work harder.
Eye drops can be used temporarily to make it more difficult for the stronger eye to see correctly. This leads to the weaker eye working harder. Eye drops contain medication, like atropine.
Atropine temporarily relaxes the ciliary muscles in the good eye. This makes the lens of the eye unable to focus for several hours. Eye drops are used once a day after waking up in the morning. The effects last for several hours up to about two weeks.
Questions and Answers
How is a lazy eye treated if it is caused by a squint?
If strabismus causes amblyopia, it is often treated with an eye patch. Sometimes glasses are required too. This is because many children with strabismus also have a refractive error.
In more severe cases, eye muscle surgery may be required.
How can I fix my lazy eye at home?
A lazy eye can be treated at home with glasses, patching, or eye drops. However, in some cases, eye surgery may be necessary.
Do lazy eyes go away?
A lazy eye does not go away on its own. If a lazy eye is identified and treated in early childhood, reduced vision can be prevented. However, if left untreated, amblyopia can lead to permanent vision loss in the affected eye.
How long does it take to cure a lazy eye?
With proper treatment of a lazy eye, vision improves within weeks to months. In some cases, treatment may last from six months to two years. Depending on the child’s age, when treatment is initiated, and the severity of the problem, a lazy eye may not be completely cured.
The younger the child is when a lazy eye is diagnosed, the more successful treatment is likely to be. Treatment is less successful if it’s started after the age of 6, and it’s unlikely to be successful if it’s started after the age of 8.
The 2 main treatment options for a lazy eye are:
- treating or correcting any underlying eye problems
- encouraging the use of the affected eye so vision can develop properly
Treating underlying eye problems
Short- or long-sightedness, can be corrected using glasses. These usually need to be worn constantly and checked regularly.
Glasses may also help to straighten a squint, and in some cases can fix the lazy eye without the need for further treatment.
Your child may say they can see better without their glasses. This is because their eyes have become used to working hard to focus and they now find it difficult to let the glasses focus for them.
They’ll need plenty of encouragement to wear their glasses continuously.
Contact lenses are an alternative to glasses, but they may only be suitable for older children.
In children, most cataracts are removed to allow better development of vision in the affected eye.
Cataract surgery for children is carried out under general anaesthetic. The procedure usually takes 1 to 2 hours.
Your child may be kept in hospital overnight to check their recovery, and will have to use eyedrops afterwards.
In some cases, surgery is used to improve the appearance of a squint. The operation will either strengthen or weaken the eye muscles of the lazy eye to change its position.
This means the lazy eye will appear to be better aligned with the good eye. The child’s vision won’t improve, but their eyes will appear straighter and it will help the eyes work better together.
A droopy eyelid can also be corrected using surgery.
Encouraging use of a lazy eye
A number of different treatment options can be used to encourage your child to use the affected eye.
Using a patch
This involves placing a patch with a sticky rim over the “good” eye so the lazy eye is forced to work. It can be very effective in improving the sight in the lazy eye. Patches often need to be worn with glasses.
The length of time the child will need to wear the patch will depend on how old they are, how serious the problem is, and how much they co-operate with wearing the patch.
Patches are most effective before a child reaches 6 years of age. Most children will need to wear the patch for a few hours a day for several months.
Using a patch to treat a lazy eye can be time-consuming and can often be an unpleasant experience for the child until they get used to it. This is understandable – from their point of view, you’re making their vision worse by taking their good eye away from them.
This is why the most important thing for you to do is explain the reasons for using a patch, and the importance of sticking with the treatment, to your child so that they’re motivated to do it.
If your child is too young to understand, try to think of incentives to encourage them to use the patch. While the patch is on, they should do close-up activities, such as playing with an electronic tablet, colouring, reading or schoolwork. Reward them with their favourite television programme.
Atropine eyedrops can be used to blur the vision in the good eye. They expand (dilate) the pupil of the good eye and blur vision, which encourages the child to use the lazy eye.
Side effects that can occur after using eyedrops include:
- eye irritation
- reddening (flushing) of the skin
However, these side effects are usually rare and rarely outweigh the benefits of using eyedrops.
Eyedrops can be as effective as using a patch. Often the choice of eyedrops or patches is a matter of preference. Children who do not like having drops in their eyes can wear a patch, and those who do not like wearing a patch can use eyedrops.
If treatment does not work
In some cases, a lazy eye does not improve despite having proper treatment.
Sometimes poor results are due to the child or family finding it difficult to stick to using the patch or the eyedrops.
If you’re having trouble with one kind of treatment, discuss the alternatives with your eye specialist.
If surgery is recommended, more than one operation may be required to improve the appearance of a squint, and glasses may still need to be worn after surgery.
If the treatment is stopped too soon, any improvements in the lazy eye can be lost. A patch may also need to be worn or eyedrops used, if the lazy eye returns.

Lazy eye is a condition marked by lowered vision caused due to anomalous development of vision during early childhood and infancy. It is regarded as the most common cause of lowered vision amongst infants and children. Lazy eye often tends to affect just one eye, but both eyes may also suffer from it. Non-treatment can result in mild to severe loss of vision.
Lazy eye may not have a noticeable underlying ocular abnormality. It generally occurs due to impaired stimulation of the nerve pathways present between the eyes and the brain. The weaker eye may wander and resultant poor vision in one eye can then trigger the brain to concentrate on just one eye, eventually causing the brain to totally disregard the signals of the weaker or the lazy eye.
Doctors may use eye drops, eye patches, contact lenses or glasses to correct a lazy eye. On occasions, it may need surgical intervention.
Symptoms of lazy eye
Some of the signs and symptoms of lazy eye are listed below:
- The affected eye may wander outwards or inwards
- Patients may elicit improper perception of depth
- The eyes may not seem to work in tandem.
On occasions, only an eye exam may be able to detect a lazy eye.
It is possible for any kind of ocular abnormality which causes crossing of the eyes or blurred vision to be diagnosed as a lazy eye. It is often caused due to 3 main causes as mentioned below:
- Due to deprivation: Any kind of issue in one eye such as cataract or a cloudy section in the eye lens, etc. can ‘deprive’ clearness of vision in that eye in the affected child, leading to lazy eye.
- Due to strabismus: Strabismus is a condition marked by some imbalance in the ocular muscles, the muscles which hold the eyes in its position. Such muscle imbalance hampers the proper co-ordination of the eyes and prevents them from working in tandem, thereby making the eyes to turn out or cross in. It is considered as the most common cause of lazy eye.
- Due to refractive problems: A substantial difference in the vision capacities of each eye, which may occur due to farsightedness, nearsightedness, or astigmatism, i.e., some kind of abnormality on the ocular surface, can cause this form of lazy eye. The vision problems associated with such lazy eye can be generally remedied via use of contact lenses or glasses.
Other causes of lazy eye: Babies who have a low birth weight or are born prematurely are at greater risk to developing lazy eye.
- Lazy eye has a tendency to run in families.
- Babies with a family history of serious ocular conditions or childhood cataracts are also at increased risk.
- In some cases, a wandering or lazy eye may be one of the first signs of ocular tumor.

How to fix a lazy eye?
There are many ways to get rid of a lazy eye. The treatment is typically dependent on the severity of vision problems. It generally commences during early childhood when the complex network and connections between the brain and the eye are in the stages of development.
A few ways to get rid of a lazy eye are listed below:
- Eye drops: Doctors may recommend the use of a drug known as atropine to be used on the better eye, one or 2 times a week. The eye medication will blur the vision in the better eye and trigger the brain to make use of the weaker eye. It may be noted that such eye drops will not prove to be effective if the better eye suffers from nearsightedness.
- Eye patches: Doctors may suggest the use of an eye patch over the better eye so as to help stimulate the lazy eye. Wearing the eye patch, 4 to 6 hours per day, will most likely benefit a majority of affected children over the age of four years. This therapy also stimulates that section of the brain associated with vision regulation to develop more fully.
- Corrective glasses/lenses: If the lazy eye is caused due to underlying ocular conditions such as farsightedness, nearsightedness, astigmatism, etc., then the doctors will typically suggest the use of contact lenses or corrective glasses. They often prove to be sufficient in getting rid of a lazy eye.
- Surgery: The ocular muscles may need to be surgically repaired if the eyes wander apart or cross. Surgery may also become necessary if the affected child has cataracts or drooping eyelids.
It may be noted that contact lenses and glasses may be adequate to get rid of a lazy eye in some children, while others may also need to go for eye drops and/or eye patches. New ‘active’ treatment options such as computer games, puzzles, drawing, etc., may also be used along with the passive treatment options like patches and eye drops to fix a lazy eye.

Lazy eye (amblyopia) is a condition in which there is poor vision in one eye due to a problem in how the brain and the eye work together, and the brain is unable to properly register the sight from one eye. This causes the brain to rely more on the stronger eye, resulting in vision in the weaker eye getting worse.
Lazy eye begins in childhood, affecting about 3% of children.
How to Fix a Lazy Eye
Early treatment works well to cure lazy eye and prevent long-term vision problems.
Treatment for lazy eye includes:
- Glasses or contact lenses
- For nearsightedness
- For farsightedness
- For astigmatism
- To treat cataracts
- To fix droopy eyelids
- To strengthen muscles if due to crossed eyes
- Training the weaker eye by making it work harder so it can get stronger
- An eye patch worn over the stronger eye so that eye can’t see
- Eye drops to put in the stronger eye to blur vision in that eye
Vision may start to improve within a few weeks but it usually takes months to get the best results. Children may need to continue to use the treatments on occasion to prevent the lazy eye from returning.
What Causes Lazy Eye?
Causes of lazy eye include:
- Crossed eyes (strabismus)
- Refractive errors
- Nearsightedness (difficulty seeing things far away)
- Farsightedness (difficulty seeing things up close)
- Astigmatism (which can cause blurred vision)
- Cataracts (uncommon in children)
Risk factors for developing lazy eye include:
- Premature birth
- Being smaller than average at birth
- A family history of lazy eye, childhood cataracts, or other eye conditions
- Developmental disabilities
How Is Lazy Eye Diagnosed?
Lazy eye is usually diagnosed with a routine vision screening. All children ages 3 to 5 should have their vision checked.
If the doctor suspects a child has lazy eye, you will likely be referred to an ophthalmologist (an eye specialist) for a more detailed eye exam.
What Can Happen Without Lazy Eye Treatment?
Complications of untreated lazy eye may include:
- Irreversible, lifelong decrease in vision
- Reduced sharpness of vision
- Reduced contrast sensitivity
- Spatial distortion
- Impaired contour detection
- Learning impairment
- Worsening of crossed eyes (strabismus)
A “lazy eye” is a childhood condition where the vision does not develop properly. It’s known medically as amblyopia.
It happens because one or both eyes are unable to build a strong link to the brain. It usually only affects one eye, and means that the child can see less clearly out of the affected eye and relies more on the “good” eye.
It’s estimated that 1 in 50 children develop a lazy eye.
How to tell if your child has a lazy eye
A lazy eye does not usually cause symptoms. Younger children are often unaware that there’s anything wrong with their vision and, if they are, they’re usually unable to explain what’s wrong.
Older children may complain that they cannot see as well through one eye and have problems with reading, writing and drawing.
In some cases, you may notice that one eye looks different from the other. However, this is usually a sign of another condition that could lead to a lazy eye, such as:
- a squint – where the weaker eye looks inwards, outwards, upwards or downwards, while the other eye looks forwards
- short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism
- childhood cataracts – cloudy patches that develop in the lens, which sits behind the iris (the coloured part of the eye) and pupil
If your child is too young to tell you how good their vision is, you can check their eyes by covering each eye with your hand, one at a time. They might object to covering the good eye, but they might not mind if you cover the lazy eye.
If they try to push your hand away from one eye but not the other, it may be a sign they can see better out of one eye.
When to get medical advice
Lazy eye is often diagnosed during routine eye tests before parents realise there’s a problem.
If you want to be reassured about your child’s vision, they can have their eyes tested when they’re old enough to attend a sight test at a high-street opticians, which is usually after they’re 3 years old.
All newborn babies in the UK have an eye test in the first days of life, and then again at 2 to 3 months old, to look for eyesight problems such as cataracts. Problems like squint and short or long sight may not develop until the child is a few years old.
It’s difficult to treat lazy eye after the age of 6, so it’s recommended that all children have their vision tested after their fourth birthday. This is the responsibility of your local council, which should organise vision testing for all children between 4 and 5 years of age.
You can also visit your GP if you have any concerns about your child’s eyesight. If necessary, they can refer your child to an eye specialist.
Causes of a lazy eye
The eyes work like a camera. Light passes through the lens of each eye and reaches a light-sensitive layer of tissue at the back of the eye called the retina.
The retina translates the image into nerve signals that are sent to the brain. The brain combines the signals from each eye into a three-dimensional image.
A lazy eye happens when the brain connections responsible for vision are not made properly. To build these connections, during the first 8 years of a child’s life, the eye has to “show” the brain a clear image. This allows the brain to build strong pathways for information about vision.
A lazy eye can be caused by:
- a reduced amount of light entering the eye
- a lack of focus in the eye
- confusion between the eyes – where the 2 images aren’t the same (such as a squint)
Left untreated, this can lead to the eye’s central vision never reaching normal levels.
Treatment for lazy eye
In most cases it is possible to treat a lazy eye, usually in 2 stages.
If there’s a problem with the amount of light entering the eye, such as a cataract blocking the pathway of light, treatment will be needed to remove the blockage.
If there’s an eyesight problem such as short or long sight or astigmatism, it will first be corrected using glasses to correct the focus of the eye. This often helps correct a squint as well.
The child is then encouraged to use the affected eye again. This can be done using an eye patch to cover the stronger eye, or eyedrops to temporarily blur the vision in the stronger eye.
Treatment is a gradual process that takes many months to work. If treatment is stopped too soon, any improvement may be lost.
Treatment for lazy eye is most effective for younger children. It’s uncertain how helpful it is for children over 8 years of age.

Amblyopia, more commonly referred to as a lazy eye, is a relatively common condition. It occurs in about 3% of children and involves one eye being weaker and having poorer vision than the other eye.
Although there’s some stigma surrounding the term “lazy eye,” it’s important to note that a lazy eye is not a reflection of character. It doesn’t mean that you’re lazy — it is an uncontrollable health issue with your eyes — and it can be treated with a number of methods.
Without treatment, the eye will become even weaker, which is why it’s so important to fix a lazy eye. Here’s what you need to know about what causes a lazy eye and how to effectively treat it.
What is a lazy eye?
A lazy eye is when there is poor vision in one eye, and vision relies on the stronger “good” eye. It is the result of a problem with the connection between the eye and the brain. A lazy eye usually develops early in life.
When the vision in one eye is abnormal, neural connections, or brain signals, won’t be properly stimulated, and the signals that are sent to the brain will create a blurred image, says Jill Rotruck, MD, an ophthalmologist and assistant professor of Ophthalmology and Visual Sciences at the Yale School of Medicine.
There are three main causes of a lazy eye, Rotruck says. They are:
- Uncorrected refractive error. This is when there is an uncorrected vision problem, such as nearsightedness, farsightedness, or astigmatism.
- Strabismus. This is when the eyes are misaligned.
- Stimulus deprivation. This is when something is blocking the vision.
Amblyopia itself doesn’t result in a change in appearance to the eye, says Rotruck. If the lazy eye is caused by an uncorrected refractive error, both eyes may appear normal.
However, in the case of strabismus, the eyes may be misaligned, with one eye wandering inward or outward. Additionally, if the amblyopia is caused by something blocking the vision, this will be visible, such as a droopy eyelid, scar in front of the eye, or cloudiness of the eye’s lens.
How to fix a lazy eye
Depending on the individual’s situation, there are various ways to fix a lazy eye. While the methods are very different, they mainly have the same goal, which is to address the underlying cause and force use of the weaker eye.
Some examples of treatment include:
1. Corrective glasses
One way to correct a lazy eye is by using glasses that deliberately blur the image that the stronger eye sees. This is usually done by using an incorrect glasses prescription, known as optical penalization.
By blurring the image that the stronger eye sees, Rotruck says the brain will be forced to pay attention to the weaker eye, and strengthen the connection between the brain and the weaker eye. Contact lenses can be used in the same way, however, if the patient is a very young child, it’s much more likely for glasses to be used.
According to the American Academy of Ophthalmology, corrective glasses are a very common first-line treatment for amblyopia. This method is highly effective for amblyopia. A 2006 study showed that there was a significant improvement in 77% of participants. Furthermore, the condition was fully resolved in 27% of participants.
2. Eye patches
Rather than blur the vision in the stronger eye, an eye patch takes away the vision in the stronger eye completely, which will also strengthen the weaker lazy eye by strengthening the connection between the brain and the weaker eye. Rotruck says treatment will vary from wearing the patch for two to six hours a day, to all day in some cases.
This treatment has been shown to be effective. A 2006 study found that 2 hours of daily patching resulted in a modest improvement of moderate to severe amblyopia.
3. Medicated eye drops
The most common form of medicated eye drops for lazy eyes is atropine drops. Rotruck says these work by preventing the stronger eye from focusing, which causes blurred vision. This involves putting the eye drops in the stronger eye, which forces the patient to use the weaker eye more, says Rotruck. These drops are typically prescribed to be used two days a week.
Two 2009 studies found that weekend atropine eye drop was effective in improving severe amblyopia over the course of 18 weeks.
4. Bangerter filter
A Bangerter filter is another way to blur the better-seeing eye’s vision. This is a special type of filter that is put on the lens of the glasses of the better eye, making the view through the lens hazy, says Rotruck.
This forces the lazy eye to be used more. The filter will be used until the patient’s eye doctor determines that the treatment is no longer needed. According to the American Academy of Ophthalmology, this method is not as popular as the others.
A 2009 study found that using a Bangerter filter along with corrective lenses works more quickly than using corrective lenses alone.
In some cases, surgery is necessary for amblyopia if the cause is stimulus deprivation, meaning something getting in the way of the vision such as a droopy eyelid, cataracts, or scarring.
“Clearing the obstruction will allow clear signals to reach the brain and the brain to learn how to see normally out of each eye,” says Rotruck.
Ultimately, the best treatment for a lazy eye will be determined by the patient’s doctor. The doctor will decide which method to use and how long to use it for. Some patients will see improvement within weeks, but in other cases, it can take months or longer to fully treat amblyopia.
Lazy eye is estimated to affect up to 5% of all adults.
For many decades, it has been thought that only children under the age of 10 could be successfully treated for amblyopia (lazy eye). In other words, lazy eye treatment was usually not provided to children older than nine.
However, the National Eye Institute (NEI) recently funded a study that found that lazy eye can be successfully treated at least up to age 17 and even adults!
Now, lazy eye can be effectively treated in high school and college student and even adults!
What is lazy eye?
Lazy eye, also known as amblyopia, is a neuro-developmental vision condition that is caused when one eye is unable to achieve normal visual acuity or does not allow the full development of 3D vision.
A lazy eye typically affects the vision or visual function of the affected eye, causing blurred vision which contributes to poor depth perception and binocular vision.
Amblyopia may develop due to other vision conditions such as a wandering or crossed eye (strabismus), or unequal vision in the two eyes caused by nearsightedness, farsightedness or astigmatism.

Symptoms of lazy eye
Common symptoms of lazy eye:
- One or both eyes may wander inward or outward
- Both eyes may not seem to be working together
- Poor depth perception
- Squinting or shutting one eye in order to see
- Tilting one’s head in order to see
- Frequent eye strain, eye fatigue, or headaches
If you experience any of these symptoms, contact an eye doctor near you who diagnoses and treats lazy eye.

Are eye exams important?
Yes, frequent eye exams are essential as the earlier a lazy eye is detected, the higher the chances of successful treatment.
In many cases, amblyopia is detectable during a comprehensive eye exam. In addition, if there is a family history of lazy eye, it is crucial that your eyes be examined regularly, as lazy eye can be an inherited condition.
Specific tests are used during eye exams to assess both the visual acuity and the visual skills of each eye. This enables your eye doctor to diagnose a condition such as lazy eye.
Adult lazy eye treatment
For many years it was believed that amblyopia was only treatable in children, often those who are 10 years of age or younger. However, this isn’t necessarily the case. While every patient is different, many adults can see results from amblyopia treatment.
The visual system which consists of the brain, eyes, and visual pathways, can be retrained due to the brain’s plasticity.
For amblyopia, specifically, binocular vision needs to be retrained, as this is the root cause behind a lazy eye.
With poor binocular vision the two images that the eyes see cannot be combined into one single image, but due to the plasticity of the brain, this does not have to be permanent.
While treatment is most effective when it’s given at an early age, it is still possible at any age to retrain the visual system, restore binocular vision, and correct amblyopia.
Lazy eye and vision therapy
Vision therapy is an effective treatment method for amblyopia. It has been shown to greatly improve the visual skills of the lazy eye by re-training the visual system.
Through vision therapy, the two eyes will be trained to work together to achieve clear and comfortable binocular vision.
Some vision therapy programs that treat amblyopia work to improve these visual skills:
- Accommodation (focusing)
- Fixation (visual gaze)
- Pursuits (eye tracking)
- Saccades (switching eye focus, “eye jumps”)
- Spatial skills (eye-hand coordination)
- Stereopsis (3-D vision)
Schedule an eye exam and vision evaluation for a proper diagnosis of lazy eye and to discuss whether a vision therapy program is the appropriate treatment for you.
Researchers at the University of Maryland have developed a method that helps an adult recover function in an eye that has been damaged and dysfunctional from birth.
The study may help treat Amblyopia, or lazy eye as it showed that complete visual loss promoted subsequent recovery in an eye that has had severely compromised vision throughout life.
Clinical studies have demonstrated that the probability to recover amblyopia, caused by unilateral cataract, depended on the age at which the cataract was removed. The probability to recover fully was maximum when the cataract was removed by the age of three.
Similar to what cataract does, the experimental occlusion caused rapid fall in deprived eye’s acuity. Earlier researches have established that an eye cannot recover normal visual function if the occlusion was removed in adulthood.
“However, when we placed the subjects into a light-tight dark room for a period of complete visual deprivation prior to removing the occlusion, we were able to produce a rapid recovery of visual acuity after removal of the occlusion” Nature quoted Yan He, as saying.
“Dark exposure drives down the strength of the synapses serving the two eyes, restoring the symmetry that was previously lacking in the amblyopic adult,” Quinlan said.
“The decrease in synaptic strength combined with the restoration of symmetry may allow the visual cortex to be more plastic and respond to changes in subsequent visual input,” Quinlan added.
One of the most frequently occurring optical conditions is having a lazy eye. It affects up to three percent of children, staying with them even as they mature into fully grown adults. Although having a lazy eye is often not debilitating, it can cause reduced vision in the affected eye.
Technology has rapidly developed to address several visual development disorders, especially myopia and hyperopia. An immensely popular form of treatment is laser eye surgery, which has proven to be effective at correcting problematic vision. However, you may be wondering if laser eye surgery can also fix a lazy eye.
Here’s what you need to know about the condition and whether it can be treated with laser eye surgery:
What is a Lazy Eye?
A lazy eye, known as amblyopia, happens when a developing brain favours one eye over the other. There are two causes of this. The first is when the eyes are misaligned, known as strabismus, and looks like having crossed eyes. In this case, both eyes do not look in the same direction at the same time, which makes it difficult for the brain to process the visual perception of their surroundings.
The second cause is anisometropia, or when the eyes have varying amounts of refractive error. The brain then focuses on the better working eye and neglects the other eye. The neglected, weaker eye starts to lose vision over time.
How Does It Occur?
It occurs fairly frequently, with around two to three children out of a hundred experiencing inconsistency in their eyes at birth. However, if this isn’t treated in time, this can develop into amblyopia.
Wearing corrective glasses can effectively treat these misalignments or errors to help strengthen the weaker eye. This must be done as soon as possible because the optical pathways between the brain and eye fully develop once a child reaches seven years of age, complicating treatment. In this case, amblyopia will continue well into adulthood.
Can It Be Fixed?
Once these pathways fully establish, it is usually not possible to correct a lazy eye. It becomes a neurological problem since the brain underutilizes the eye, so the direct treatment to the eyes will not improve the condition. While it can improve vision in the lazy eye, it won’t fix the alignment problem.
Still, many patients with amblyopia continue to opt for laser eye treatment. Many of them depend on glasses or lenses to correct their vision, which laser eye surgery does in a more effective, permanent, and convenient manner. This surgery can boost vision so successfully that patients typically no longer need their glasses or use them as often.
However, each case of amblyopia is different. Only proper consultation with a professional will provide a more comprehensive understanding of your situation. Sometimes, surgery is still possible if the lazy eye is not notably weaker.
Additionally, laser eye surgery that treats farsightedness or astigmatism can prevent the development of amblyopia later. This is because the brain may begin to snub the problematic eye and focus on the stronger one. As laser eye surgery corrects refractive errors, this stops the brain from favouring one eye.
Although laser eye surgery cannot correct a lazy eye in misalignment, it can improve its vision. It will prevent eye deterioration, maintain optimal eyesight levels, and eliminate the need for glasses to help correct problematic vision problems. However, consulting with an ophthalmologist is the best way to determine your optical condition’s most advantageous solutions.

Q1: What is a lazy eye?
A: Lazy eye is medically termed Amblyopia, is a neuro-developmental vision condition that develops when one eye is unable to achieve normal visual acuity or does not allow the full development of stereopsis (3D vision).
Q2: How does a lazy eye affect vision?
A: A lazy eye typically affects the vision or visual function of the affected eye, causing blurry vision even with corrective eyewear. The condition also commonly presents with reduced visual skills, poor depth perception, and reading difficulties.
Q3: How common is lazy eye?
A: According to research, amblyopia affects up to 1 in 33 of the U.S. population— this means up to 10 million children and adults may have a lazy eye.
While the condition typically presents in early childhood, a lazy eye can develop later on in life as well.
Q4: What causes a lazy eye?
A: The true underlying cause of lazy eye is a reaction in the brain, called suppression. Suppression occurs when the brain actively ignores some or all of the visual information coming from one eye to avoid blurry or double vision (diplopia) or ocular discomfort. Suppression can cause serious consequences, and can lead to an eye turn, also known as strabismus.
Q5: Who is at risk of developing a lazy eye?
- Premature birth
- Small birth weight
- Family history of lazy eye
- Developmental delays
Q6: Which vision conditions can cause a lazy eye?
A: Lazy eye can develop from a few different vision conditions:
- Refractive amblyopia is the most common form of amblyopia. It can be divided into two types:
- Isometropia is a significantly high, but equal optical prescription in both eyes.
- Anisometropia is a significant difference in eyeglass prescription (i.e. nearsightedness, farsightedness, astigmatism) between the two eyes.
- Constant strabismus is a constant noticeable turn of one eye in any direction. An inward turn of the eye (esotropia) is the most common. Amblyopia resulting from strabismus can be easier to detect because the noticeable eye turn alerts to a vision problem.
- Ocular obstruction can result from any physical blockage of vision, such as a cataract, trauma, lid droop (ptosis), or blocked tear duct.
Congenital disorders and vitamin A deficiency are less common causes of lazy eye.
Q7: How do I know if my child has a lazy eye?
A: Parents often have a difficult time recognizing a lazy eye because the condition usually develops in one eye, and may not present with a noticeable eye turn. Also, children generally learn how to ignore the lazy eye and compensate by mainly relying on the sight from the ‘good’ eye.
If your child presents with any of the following symptoms, they may have a lazy eye:
- Shutting one eye or squinting
- Rubbing eyes often
- Poor eye-hand coordination
- Tripping often or accident prone
- Poor depth perception
- Difficulty with fine eye movements
- Reduced reading speed and comprehension
- Poor eye focusing skills, or inability to follow an object with just the eyes
- A cross-eyed appearance
- Unusual eye movements such as flickering or blinking
Q8: How is a lazy eye diagnosed?
A: Specific tests are used during eye exams to assess both the visual acuity, depth perception and the visual skills of each eye— enabling your doctor to diagnose a condition such as lazy eye. Tests of visual skills allow your doctor to assess how well each eye is performing individually, and identify an effective eye-brain connection.

Q9: How is the lazy eye treated?
A: Lazy eye can be treated through different means— depending on the type, severity, and age of the patient. A variety of treatment options have been shown to strengthen the eye-brain connection necessary for improved binocular vision.
Corrective eyewear is prescribed to ensure that each eye has the highest visual acuity possible. According to the Pediatric Eye Disease Investigator Group (PEDIG) research, 77 percent of children with refractive amblyopia showed improved vision acuity within fifteen weeks of wearing corrective eyeglasses.
However, the eyeglasses alone do not treat the underlying problem. Therefore, a treatment program of vision therapy is usually prescribed to retrain the eye-brain connections of the lazy eye.
Q10: How can vision therapy treat a lazy eye?
A: Vision therapy has been shown to greatly improve the visual skills of the lazy eye by re-training the visual system and strengthening the neural communication between the lazy eye and the brain. Through vision therapy, the two eyes will be trained to work together to achieve clear and comfortable binocular vision.
A vision therapy program to treat lazy eye may include activities that focus on improving the following skills:
- Accommodation (focusing)
- Fixation (visual gaze)
- Saccades (eye jumps)
- Pursuits (eye tracking)
- Convergence (binocular vision)
- Spatial skills (eye-hand coordination)
- Stereopsis (3-D vision)
Q11: How does eye patching work?
A: Eye patching is usually recommended together with a vision therapy program. An eye patch is placed over the stronger eye— forcing the lazy eye to work and develop stronger neural connections to the brain. Vision is recovered as the brain begins to acknowledge and process visual signals coming from the lazy eye.
Q12: How long will my child need to wear an eye patch?
A: This will be determined by the extent of the lazy eye. Recent research conducted by the PEDIG team has proven that eye patching for a moderate lazy eye is effective when worn for only two hours per day with one hour of near vision exercises. The research revealed that:
- 62% of patients that patched for two hours per day showed improved visual acuity within about four months of treatment.
If your child is showing signs of a lazy eye, or any other vision problem, schedule an eye exam for a comprehensive assessment of your child’s vision and ocular health.
Discuss any concerns you may have with your eye doctor— the earlier a vision problem is detected, the sooner your child will be able to achieve clear and comfortable vision.
Schedule an eye exam with an eye doctor near you to assess your child’s vision so they can see clearly and comfortably.
For as long as people have existed they have been dealing with lazy eye. Different people and cultures have tried different interventions to fix it, going back more than a thousand years. Amblyopia is the medical term for lazy-eye.
Lazy Eye Treatment with Eye Patches – 900 A.D. to Present
Documented treatment methods on how to fix amblyopia, the medical term for lazy-eye, date back to about 900 A.D. At that time, Thabit Ibn Qurrah of Mesopotamia wrote that lazy eye (amblyopia) due to strabismus (misaligned eyes) should be treated by eye patching (occluding or occlusion of) the “normal eye”. From the beginning, it was believed that the blocking or occlusion of the “normal” or “good eye” would force the use of the so-called “lazy eye”, and therefore improve its vision. George Louis Leclerc, Count de Buffon (1743) was later given credit for the use of eye patching to treat amblyopia (the medical term for lazy eye). In the 20th century, eye doctors throughout the world depended heavily on the use of eye patches for lazy eye treatment and the amblyopia eye patch was prescribed for many hours per day. In the 21st century — to the great relief of many parents and their children — scientific research proved that two hours of eye patching per day with one hour of near visual activities as eye exercises is just as effective as six hours of patching per day.
Lazy Eye Treatment with Eye Muscle Exercises or Orthoptics – 19th Century to Present
Eye Treatments with Drugs (Eye Drops) – from Cleopatra to the Present
In the 20th century, drugs became an alternative to eye patches for lazy eye treatment when the use of atropine eye drops was adopted as a new way of blocking the vision of the “good eye”. The atropine eye drops blur the vision in the “good eye” instead of covering it with an eye patch. The blurring of the “good eye” stimulates the brain to make greater use of the image coming from the lazy eye.
Atropine was first synthesized in a laboratory by German chemist Richard Willstètter in 1901, however, plant extracts of atropine (eye drops made from deadly nightshade and other plants) were used by Cleopatra for cosmetic eye dilation in the last century B.C.
How to Fix a Lazy Eye – Not Much Changed until the 20th Century!
Lazy eye treatment and correction methods really did not change much until the twentieth century. Most likely, the reason that treatment changed so little is because lazy eye is a neurological condition – the vision problem occurs in the brain – and very little was known about the brain or how to help it change or recover until the late twentieth century.
Lazy Eye Treatment with Drugs (Eye Drops) Instead of or with Eye Patches — from Cleopatra to Present
In the 21st century, we are seeing a remarkable increase in mainstream scientific studies that investigate the methods and results of existing treatments for lazy eye. These studies examine (1) the necessary frequency and length of time for effective occlusion (eye patching or atropine drops), (2) the importance of visual activities with or without occlusion and (3) the maximum age at which treatment can still be effective. Despite many new and unexpected scientific discoveries regarding the plasticity of the human brain and/or updated treatment protocols for lazy eye, the “old school” treatment methods persist and are slow to change. Eye patches or atropine drops alone are still the most common treatments for lazy eye. And, notably, older children and adults are still being told that it is too late to be successfully treated.

If you’ve been told that you or your child is too old to have amblyopia, or “lazy eye,” corrected, someone has done you a true disservice. Here’s how to fix a lazy eye.
For years, parents of older children diagnosed with amblyopia, or ’lazy eye,’ have been told the child is “too old” for the problem to be corrected. Yet we’ve helped older children and adults correct their lazy eye and enjoy improved vision.
So why are some parents being told otherwise?
The reason this misinformation continues is tied to a misinterpreted study and some long-held beliefs, neither of which will help you or your child.
(Note: At the end of this post, please check out our updates for more information on How to Fix a Lazy Eye.)
What is the Source of the Misinformation About Amblyopia?
In her book Fixing My Gaze, neuroscientist Sue Barry relates how the misconception in the scientific and medical communities began.
She writes that since the mid-1990s, the “scientific and medical communities have cited strabismus and a related disorder called amblyopia as classic examples of developmental disorders that cause permanent changes in vision if they are not corrected within a critical period in early life.”
Photo courtesy of Fixingmygaze.com
The conclusions, she states, were based on experiments by David Hubel and Torsten Wiesel at Harvard Medical School. The two studied cats that had strabismus, or misaligned eyes. It was noted that the vision in the cats had not developed normally, and that they could not see in 3D.
Many scientists and doctors assumed the cats would never acquire stereo vision because they had not acquired the ability during what is referred to as a “critical period” of vision development. In this period, it was assumed, if certain visual skills (specifically visual acuity and stereopsis) were not learned by the brain, they could not be developed later in life.
Hope With a “Plastic” Brain
Barry cites that more recent scientific research indicates otherwise. The adult brain appears to be more “plastic” than had been previously thought, and the circuitry of the brain can actually change as a result of our actions and experiences.
In the case of amblyopia, one eye has better visual acuity than the other. There is also difficulty with depth perception resulting from poor or no development of stereopsis. A child who has trouble catching and throwing objects, or is clumsy and always bumping into things may have amblyopia.
For years, medical practitioners have referred to the cat study and told people that there is no treatment for amblyopia, as the critical period had passed. But recent research and treatments using vision therapy have proven otherwise.
Steps to Fix a Lazy Eye
Knowing that the brain can be retrained, developmental optometrists use a variety of methods to get the two eyes to work as a team and see visual space accurately.
The approach begins with finding the right lens or glasses. This includes ensuring you or your child has the right prescription to minimize the “bullying” effect of the stronger eye. Patching and vision therapy, which includes a series of visual activities, may then be used in tandem to retrain the visual system.
Every case of amblyopia is different, and a functional vision test should be administered to determine the extent of the vision problem.
The good news for parents and children is that amblyopia can be corrected outside the “critical period” for vision development (from three months to three years old). And that’s critical information for any parent.
Amblyopia Case Study: Chalen
We like to feature case studies of people who have used vision therapy to overcome lazy eye. In this video, one of our former patient’s mother discusses how vision therapy helped her daughter overcome amblyopia.
You’ll note that she mentions her daughter’s eye turn — it is possible to have amblyopia and strabismus (a turned eye) at the same time. Often strabismus is what causes the amblyopia, as the brain chooses not to receive the two conflicting signals.
Watch the video and hear Chalen’s success story:
How Did We Fix Chalen’s Lazy Eye?
While the specific vision therapy treatment is different for each patient, the most effecitve method includes the following steps:
- Prescribe lenses or glasses that help a child with amblyopia
- Use patching effectively
- Retrain the brain using vision therapy
We detail these further on this page, but this was the approach used to treat Chalen. As her mother noted, it was a time-consuming process, but in the end she couldn’t believe the results. What’s even more impressive is that other doctors told her that improved vision wouldn’t be possible.
From No Hope to Functioning Vision
What really jumps out at us about this video is the fact that Chalen’s mother believed there was no hope when she came to The Vision Therapy Center.
She was certain that when The Vision Therapy Center’s developmental optometrists met with her to provide the initial diagnosis, that they would tell her what she had heard time and time again: There was no hope for correcting Chalen’s vision.
“I had no idea that her 3D vision or depth perception were being shut off,” she said. “Now that her brain is working together, the results are amazing.”
New Research on Lazy Eye
Here are just a few research links compiled by Dr. Dan Fortenbacher of WOW vision.
Video Gaming Being Used to Treat “Lazy Eye”
A trend we noticed over the past year is the use of video games to help treat a lazy eye (amblyopia).
As we’ve noted before, the condition of amblyopia isn’t simply something that affects one eye. Your entire visual system must be taken into account. Specifically, the brain must use both eyes together.
The video gaming mentioned in the post we linked to above points out the gaming can be used as an activity when patching to help improve the acuity of the eye, which is true. But simply improving the acuity may not lead to the brain using both eyes together.
When the patch comes off, the brain may go back to the old way of doing things and acuity gains may be negated. Check out our post for more details on the topic.
Lazy Eye Success Story
In the past year, we also wrote about Maya’s vision therapy success story. Her family didn’t even realize she had amblyopia. “We never thought anything was wrong,” her mother Molly said. Read the full story here.
You can get rid of pink eye (conjunctivitis) in various ways, depending on the underlying cause of the problem. Since pink eye usually is associated with viral or bacterial eye infections, you should visit your eye doctor to determine the cause and appropriate treatment.
Topical antibiotics often are prescribed to treat conjunctivitis caused by bacteria. If the cause of your pink eye is viral, you may need to wait it out for a few weeks while the disease runs its course.
You typically can’t get rid of viral pink eye, but you can relieve symptoms through remedies such as eye drops containing antihistamines, decongestants or both.
You also can relieve symptoms through home remedies such as applying warm or cool compresses — whichever feels better — to the outer, closed eyelids.
If you have eye allergies, your eye doctor might recommend topical eye drops containing antihistamines to help stop your eye from reacting to allergens such as dust, pollen and pet dander. These types of eye drops are available in both over-the-counter and prescription formulas.
If someone in your household already has pink eye because of a contagious eye infection, the best way to avoid pink eye is to take preventive measures such as frequent hand washing, avoiding use of the same washcloths and towels, and frequent use of a disinfectant on countertops and other surfaces.
Above all, don’t take chances with pink eye.
You should visit your eye doctor for an eye exam when you have a pink eye for any extended period of time or you suspect something beyond ordinary eye irritation is causing your problem.

Eye exercises for esotropia are designed to strengthen and straighten out your eye or eyes that have been effected by esotropia. Esotropia, colloquially referred to as a lazy eye or crossed eye, causes your eye to squint in such a manner that it is turned inward or down 3. While eye exercises can help patients suffering with esotropia, glasses can also help to correct the problem or alleviate the symptoms.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
This eye exercise is designed to strengthen your eye muscle and improve your lazy eye’s ability to converge properly. Start by taking a regular pencil and holding it up in front of your face. Focus with both of your eyes on a small piece of text or letter that is printed on the side of the pencil. From here, start moving the pencil closer and closer to the bridge of your nose. According to the Mayo Clinic, the exercise must be performed five days a week for 15 minutes a day. If you are doing the exercise correctly, you will perform around 100 repetitions per day of the exercise.

A lazy eye is a childhood condition that is caused when vision in one eye does not develop properly. Not only does this result in poor vision in the affected eye, it can be embarrassing for individuals if they also have a squint – which is where the eyes point in different directions. Once diagnosed, there are a number of ways a lazy eye can be treated, many of which will attempt to correct underlying conditions that may be making it worse. Afterwards, use of the lazy eye will be encouraged to help vision develop properly.
The success of treatment will often depend on an individual’s age, with younger children usually having the best chance of overcoming the problem. Any treatments started after the age of around eight are less likely to work as well. It is also important to comply with the instructions of your optometrist. Poor results from lazy eye treatment can be due to parents or children not sticking to the agreed treatment.
What lazy eye treatments are available?
The first stage to treating a lazy eye is to solve underlying problems that may be contributing to the condition. This can be done in several ways:
- Glasses: Wearing glasses will tackle any vision problems such as short- or long-sightedness. In some cases, glasses will help with a squint and may even resolve the lazy eye without further treatment. Glasses should be worn constantly and regularly checked to ensure they are still performing effectively. Encouraging children to wear glasses can be a problem, but it is important to remain motivated.Your child may say they see better without the glasses – but this is because their eyes are now used to working hard to focus and allowing the glasses to do this for them may feel uncomfortable.
- Contact lenses are an option for lazy eyes, although they are best suited for older children.
- Surgery: There are surgical approaches for helping to correct a lazy eye. One option is to try to tackle a squint by weakening or strengthening the muscles in the affected eye to change its position. While this will not help with vision, it may encourage the eyes to work better together. Surgery may also be required to remove cataracts. This will help treat blurred and distorted vision and can be carried out quickly under local or general anaesthetic.Eye drops may be prescribed and the use of an eye patch is often recommended following the procedure.
Using the lazy eye: Once the underlying conditions have been tackled, it is time to begin encouraging use of the lazy eye. Covering the good eye with an eye patch or applying eye drops are the most common methods for doing this. Eye drops cause the pupil to dilate, which blurs near vision. An eye patch prevents the good eye from being used at all. Both treatments are quite effective and the one you choose will often be a matter of preference.Eye drops may cause some side effects, including:
- Eye irritation
- Reddening of the skin
Early diagnosis and treatment for a lazy eye are important in order to treat the condition successfully. We’d recommend you take your child for an eye examination from about the age of four to look out for any signs. If you have any concerns about your child’s eyesight, or you’d like to know more about your lazy eye, pop in and see us.
What is lazy eye?
A lazy eye, also known as amblyopia, is quite a common condition in children and happens when vision hasn’t fully developed, usually in one eye. For various reasons, vision development in children might not take place properly, so those strong links with the brain needed for us to see clearly aren’t quite there yet.
Lazy eye symptoms
There are many signs and symptoms that help identify lazy eye, however quite often it is only picked up at a full eye examination.
- An eye that wanders inward or outward
- Poor depth perception
- Squinting or shutting an eye
- Titling of the head
It can be difficult without an eye test to tell if a child has a lazy eye, particularly if they’re too little to tell you what their vision is like. One way to tell is to cover one eye at a time – you may find that they’re quite happy having one covered but might push your hand away if you cover their ‘good’ eye.
Lazy eye causes
Lazy eye in children
Most instances of lazy eyes develop when we are children. All of us are born with very poor vision, but it steadily develops through childhood until about the age of eight. It’s important for the brain to receive clear images from the eyes during childhood in order to the build the strong connections we need for good vision. For some children with a lazy eye, these connections aren’t made properly which results in one eye being permanently blurry, even with glasses or contact lenses.
A lazy eye in children can be caused by:
- Very long or short sight in one eye
- A squint – a condition where the eye muscles do not work properly, and one eye looks inwards or outwards
A problem with light entering the eye, for example with a congenital cataract
Lazy eye treatments
Treatment will depend on the underlying cause of a lazy eye, but it is usually treatable. in young children.
If the lazy eye is caused by very short or long sight in one eye, glasses may be prescribed in order to correct the focus, usually with patches. The healthy eye will be covered with a patch, to allow the independent use of the lazy eye. This will be a gradual process, over many months.
If the lazy eye is caused by a problem with light entering the eye, such as a cataract, then that condition will need to be treated.
Lazy eye treatment is most effective in children under 8 years old, as it gets a bit more difficult to treat as they get older. So it’s important to get a lazy eye checked sooner rather than later for the best chance of successful treatment
Lazy eye diagnosis
A lazy eye is diagnosed through an eye examination. The earlier the diagnosis, the easier it is to treat, so we’d recommend taking your child to screen their vision when they’re 3, 4 or 5 to check the overall health of their eyes, including whether they might have a lazy eye.
School eye screening may not pick up less severe lazy eyes, so it’s best to have a full eye examination. Don’t forget that all children under-16 receive an NHS-funded eye test.
If you have any concerns about your child’s eyesight or you’d like to know more about your own lazy eye, you should visit your optometrist.
Home eye care Lazy Eye in Kids – A Problem that can Threaten the Vision
Lazy eye is a visual impairment that is usually seen in early childhood years. In fact, 2 out of every 100 children are affected by this condition. Though this is concerning, lazy eye in kids can be treated. But first, it’s important to know what lazy eye is and how it can be cured.
What is lazy eye?
Also known as amblyopia, lazy eye is a visual condition in which the brain favors one eye more than the other. An eye is affected by amblyopia because of a number of conditions that prevent it from properly focusing and communicating with the brain. As a result, the brain ends up favoring the other eye.
The most common cause of amblyopia or lazy eye in kids is a weakness or an imbalance in the muscles responsible for positioning the eyes. It prevents the eyes from properly working together.
Effects of Lazy Eye in Kids
These are the signs you need to look out for if you think your kid may be affected by lazy eye or amblyopia:
- A wandering eye
- Misaligned eyes
- Poor depth perception
- Rubbing one eye
- Head tilting
- Problems with reading and writing
As the kid grows and the condition progresses, they could be prone to more serious risks. In severe cases, lazy eye can also lead to loss of vision. Therefore, it is best to detect the problem as early as possible and understand your kids’ options for amblyopia treatment.
How can I tell if my child has amblyopia?
The signs of lazy eye in children can be easily noticed if you pay just enough attention. The first sign you should look for is misaligned or crossed eyes. This symptom indicates strabismus in which the brain bypasses the visual information that the lazy eye receives.
If you suspect the problem, you can get an eye patch for kids since children with lazy eye complain of blurry vision when their dominant eye is covered. To confirm the diagnosis, consult a certified and experienced optometrist, who may use the test called photo screening, which estimates the child’s eye alignment and helps look for a potential problem.
Lazy Eye Treatment
Glasses – Lazy eye in children can be corrected with glasses sometimes. Children with far-sightedness, near-sightedness, or astigmatism are usually prescribed glasses. The specialist monitors the improvement in vision and lazy eye, and suggests the course of treatment, if needed, after that.
Occlusion or Eye Patch – It is one of the most effective lazy eye correction method. In this treatment, the good eye is covered with a patch so that the lazy eye starts working. With the patch on, the brain will only receive information from the lazy eye, and hence, will not ignore it. The patch must be worn for a few hours every day. Also, children should be encouraged to read, color, write, or do other close-up activities while wearing the patch.
Atropine Eye Drops –Another effective amblyopia treatment, atropine eye drops are used to dilate the pupil and blur the vision in the good eye. It has the same results as an eye patch and is less awkward for children.
Vision Exercises – Vision exercises are really helpful and can be done in combination with other treatments.
Lazy Eye Surgery – Lazy eye surgery may be recommended when no other treatment works. It usually results in better eye alignment and also improves the appearance of the eye.
Amblyopia is a serious vision problem that can even lead to blindness. But the good news is that it is treatable in kids. Therefore, it is important to fix lazy eye in children as early as possible.
Consult the experts at InSight Vision Center and ensure the most comfortable and friendly lazy eye treatment for your child.
Dilating the pupils of the eyes helps an ophthalmologist see the internal structures, consisting of the lens, optic nerve, blood vessels, and retina. Dilation involves the use of individual eye drops that either stimulate contraction of the muscles surrounding the pupil and relaxes the muscles so that they open.
Dilation is an essential component of a detailed eye exam, enabling medical professionals to determine and identify eye issues that they may otherwise not see. The American Academy of Ophthalmology presently recommends that adults regularly go through such exams starting at age 40.
What Is the Pupil
The pupil resembles camera aperture because it becomes bigger or smaller size, depending on how much light is required. To do this, the pupil will undergo miosis, in which the constriction of pupil triggers it to close, or mydriasis, in which is the dilation of the pupil enables it to open.
The pupil size manages by both the sympathetic nerve system (the “fight or flight” reaction) and the parasympathetic nervous system (the converse action in which the body slows high energy functions).
The pupil size can alter for numerous reasons. It could change in action to the quantity of light it is exposed to. It can likewise adjust when an individual ends up being excited, such as in reaction to sexual stimuli, or is faced with emotional stress. It is believed the “battle or flight” action is an evolutionary one, enabling more light into the eye so that the body can respond quickly to potential harms.
Common Duration of Pupil Dilation
Dilating the eyes is the main part of an eye test. It includes the administration of 2 or 3 drops administered straight into the eye. Depending on what the physician is trying to accomplish and how large the pupil requires to be, various types of eye drops might be used, consisting of:
Eye drops are put in both eyes so that the retina, macula, and optic nerve can be taken a look at carefully using a portable light and magnifying lens. While the dilation itself is not uncomfortable, it can be exceptionally unpleasant as the eye has no ways by which to protect itself from light.
After a dilated eye examination, your pupils will usually remain open for about 3 to four hours, often longer. This time varies according to the kind of drops utilized, as well as the color of your eyes. By and large, dark-colored eyes have shorter dilation periods, while light-colored eyes might stay open to eight hours.
Children, meanwhile, are typically dilated with more powerful drops to enhance the precision of the test. It is not uncommon for some kids to get up the early morning after a test with their pupils still wide open.
Uncommon Duration of Pupil Dilation
Many, however not all, drops cause an adverse effect called cycloplegia. Cycloplegia is the temporary paralysis of the muscle which allows the eye to focus on near items. In some people, this effect can last for hours. In others, it might take some days for the vision to stabilize fully.
There are circumstances where a physician will want to trigger cycloplegia intentionally. One such example remains in young kids whose focusing system is so strong that it is frequently tough to measure their vision or refractive mistake. Cycloplegic drops might also be used to eye diseases or injury that cause sharp pain and light sensitivity. One such condition is called uveitis, the inflammation of the middle layer of the eye (uvea).
Pediatric eye doctors may likewise utilize them to deal with a condition called lazy eye in which a child develops minimized vision for any variety of factors. These kinds of drops are prescribed for much more extended periods of time, approximately several months in many cases.
For many people, the side effect is annoying however not excruciating. To handle the blurred vision and level of sensitivity to light, nonreusable sunglasses are generally supplied to help reduce short-term discomfort. Unlike regular sunglasses, these block off peripheral light from the side of the lenses in addition to the front.
How to Undilate Eye Pupils
You may begin by searching for out why your eyes are dilated.
- Are they dilated because you just had your eyes examined by your eye doctor (Ophthalmologist or Optometrist)? Then the most likely answer is that dilating drops (mydriatics) have been utilized to dilate the pupil to enable the back of the eye to be taken a look at. Usually the effects will disappear in numerous hours. Nevertheless, if a more powerful mydriatic was used like homatropine or Atropine (not likely but possible) then it might take up to several days for the dilation to wear away. No treatment needed
- Are they dilated since of a medication you have been utilizing (e.g., scopolamine patch)? Then removal of the patch will permit the pupils to return to normal. Again this usually takes hours, however, could take much longer in some susceptible people. No treatment needed
- Are they dilated because of trauma to the eye that has torn the iris or damaged the pupillary sphincter muscles? Then you might require surgery to fix the iris (if possible. This is not always simple or possible).
- Are they dilated because your eye is in angle closure, or having an attack of angle-closure glaucoma? Then you need first aid
- Are they dilated since you have anterior or posterior synechiae – scarring/adhesions – that are holding the pupil in an open position. Or perhaps vitreous has stepped forward into the anterior chamber, and you have vitreous-corneal adhesions. Those may need to be lysed or released surgically.
- Are they dilated because you have a “Third Nerve Palsy”? You might want to get an emergency MRI of the brain.
- Are they dilated because you have herniated your brain stem? There’s absolutely nothing to say then, and you wouldn’t have the ability to hear or read it anyway.
- There are other things, like growths, cysts or tumors of the iris, inherited conditions like aniridia, ICE syndrome, that might make a pupil appearance dilated.

- Amblyopia occurs when eye develops abnormally in early life — the weak, or ‘lazy’, eye often wanders inwards or outwards.
- If left untreated, amblyopia can lead to permanent vision loss in the affected eye.
- You should take your child to your doctor if they show any signs of amblyopia, such as eyes that don’t seem to ‘work together’.
- There are many treatment options for amblyopia, including glasses, contacts, an eye patch and surgery.
- Amblyopia can return after treatment, so it’s important to continue monitoring your child’s condition.
What is amblyopia?
Amblyopia is a condition where one eye develops abnormally in early life. The weak, or ‘lazy’, eye often wanders inwards or outwards. In rare cases, both eyes can be affected. If left untreated, amblyopia can lead to permanent vision loss in the affected eye.
The condition usually occurs in children between birth and age 7 and is the leading cause of decreased vision in one eye in children. Amblyopia is more common in small or premature babies, or children with a family history of the condition.
What are the symptoms of amblyopia?
Signs that your child might have amblyopia include:
- eyes that don’t seem to ‘work together’
- an eye that wanders inwards or outwards
- squinting or shutting one eye
- head tilting
- poor depth perception
See a doctor if you notice your baby’s eye wandering in their alignment any time after the first few weeks following birth. It is also a good idea to have your child’s eyes tested before they start school.
What causes of amblyopia?
Amblyopia develops when one eye receives weaker visual signals in early life. Because the brain receives these fewer visual signals, it starts to ignore input from that eye and so the eyes do not work together properly.
Amblyopia can be caused by anything that blurs a child’s vision or causes crossed eyes. Common causes include:
- an imbalance in the muscles that position the eyes (known as strabismus)
- a difference in the sharpness of vision between the eyes
- an imperfection on the surface of the eye (astigmatism)
- any problem with one eye, such as a cloudy area in the lens (cataract)
How is amblyopia diagnosed?
Amblyopia is diagnosed using an eye test given by a doctor, community nurse, optometrist or ophthalmologist.
How is amblyopia treated?
The earlier treatment starts, the better the outcome. This is because it is important to correct amblyopia while the connections between the eyes and the brain are forming.
The type of treatment will depend on the cause of amblyopia and whether it is affecting your child’s vision. Some options include:
- glasses or contact lenses to correct conditions such as near-sightedness, far-sightedness and astigmatism
- an eye patch over the stronger eye to stimulate the weaker eye
- a special filter to blur the vision of the stronger eye and stimulate the weaker eye
- eye drops to blur the vision of the stronger eye
- surgery if your child’s eyes are wandering, or to correct cataracts or droopy eyelids
The treatment usually works within several weeks or months, although it can continue for up to 2 years.
Amblyopia can return in 25 per cent of cases (1 in 4 cases). It’s therefore important to continue to monitor your child’s eyes after the treatment stops.
If you want to know how much does lazy eye or strabismus surgery cost, then we should first note that there are 2 categories of a lazy eye: one is “Amblyopia” and the other is “Strabismus,” a condition where the eyes aren’t lined up properly. This can either be because of a weak or too strong of a muscle, triggering the eyes to point in various instructions.
Just how much does strabismus surgery cost?
For clients who do not have insurance coverage, the expenses can be less than $750 if the eye can be remedied with an easy eye examination, glasses, and further monitoring. Nevertheless, if vision therapy is needed, the expenses can be closer to the $2,000 to $3,000, if not more.
Surgical treatment, which will be the most extreme alternative, can cost anywhere from as low as $7,000 to more than $20,000 without a medical insurance plan. This ought to include the medical professional fee, hospital or clinic charges, and any other additional costs. This will depend on the medical professional, where it’s being done, the geographical area, and the complexity of the case.
Members on the Realself website paid approximately $8,000 for their lazy eye surgery, and for the most part, many considered the treatment to be worth the money.
Because the surgical treatment will be seen as a medical necessity, a lot of medical insurance plans will cover the surgery and you will be only responsible for your co-pay and deductibles.
Strabismus surgery summary
If a patient is found to have strabismus, the physician will figure out the very best treatment option. For younger individuals, a medical professional will usually advise prescription glasses and vision treatment to help with the issue, and surgical treatment will only be the last option. Prompt treatment will be needed for kids to prevent amblyopia, a condition where vision does not develop at all in one eye. The very same can be said about grownups.
If vision treatment is needed, this session will require a therapist and often an eye doctor or optometrist. Throughout these sessions, they will utilize tools and particular activities to aid train the eyes to work effectively. Seen as questionable, some eye doctors might suggest it, while others might not see it as an important treatment method.
If the approaches detailed above do not work, surgery will be the last option. Throughout the surgical treatment, the eye muscles will be either reinforced or deteriorated to aid the affected muscles. A surgeon, throughout the procedure, will either shorten a muscle to make it stronger or recess a muscle to make it weaker. Kids will be offered a general anesthetic while grownups will be treated with an anesthetic that numbs the eye.
Throughout the actual surgical treatment, the surgeon will make a little cut in the clear membrane, referred to as the conjunctiva, that covers the white part of your eyes. With access to your eyes, the surgeon will then either reduce or extend the muscles to aid straighten the eye to a natural position. To reduce the muscle, an area of a close-by tendon or muscle will be taken out, and if the muscles require to be weakened, a procedure referred to as a resection will be carried out, meaning the muscle will be extended and reattached to a point further back in the eye.
Also read our articles about the price of cataract surgery, LASIK eye surgery, and eye examination.
The typical treatment, depending upon the circumstance, can take 90 to 120 minutes. Some patients will only require one eye dealt with, while others require both eyes fixed. The same can be stated about the muscles because some individuals require more than one muscle rearranged or fixed.
This is an outpatient treatment and the majority of the time, the client can go home the very same day.
What should you expect after strabismus surgery
After the treatment is finalized, the eyes might be aching and red. Some patients even talk about seeing some bright red blood spots in the surgical area.
Some clients will see damaged capillary in the eyes, which can trigger eye inflammation. If this were to happen, it can take up to 3 weeks for it to disappear.
A weird sensation might also be experienced, comparable to having something in your eye. This will generally go away within a couple of days. Many people are able to resume activities within just a few days.
Younger individuals might require another treatment to maintain the best possible results in terms of eye health. Glasses or some type of special lenses might be required to fine-tune the eyes.
What are the additional expenses?
Throughout the surgery, general anesthesia will be needed and might be billed separately. The typical anesthesia can cost $700 to $1,100.
A follow-up consult will be required to keep track of the recovery after surgery, and this will take place about 2 weeks after your treatment. Follow up consults can cost anywhere from $75 to $200.
Medication will be needed to aid numb the discomfort for the weeks following the treatment.
Vision treatment, if required, can cost $150 to $250 per session.
The surgical treatment isn’t 100% of the time effective, and sometimes, vision loss can happen, causing a brand-new pair of prescription glasses.
Tips to remember
There are 2 conditions that can trigger a lazy eye: Amblyopia and Strabismus. Amblyopia is a developmental issue that has an eye-brain connection. With Amblyopia, the brain learns to neglect info from the “lazy eye,” triggering a weak connection between the 2. Strabismus is a misalignment, triggering the eyes to cross when the 6 muscles that surround the eye can’t focus and collaborate correctly. Considering that the eye muscles can’t line up correctly, the brain will get an almost completely different image from each eye, triggering confusion and potentially causing ignoring one image.
AllAboutVision has an article that states that LASIK can’t fix a lazy eye; nevertheless, there are some exceptions. If one eye were to have considerably more nearsightedness, farsightedness, or astigmatism than the other, there’s a minor possibility the brain might start to neglect this eye, causing amblyopia. If somebody were to be in this circumstance, using lenses might be unpleasant because the unequal zoom triggered by the lens power can lead to headaches;. The very same can be said if contact lenses were not successful. LASIK, in this circumstance, might be an excellent choice to completely fix the refractive mistakes.
Lazy eye treatment can bring improvements at any age, according to some clinical studies; nevertheless, it’s best to start the process as early as possible.
The strabismus surgical treatment success rate is around 60 to 80 percent.
How can I save some money?
A lot of cases can be treated while an individual is still young, so it is necessary to do something about it as quickly as possible. The most popular services, as pointed out above, will consist of using restorative glasses and an eye patch to assist reinforce the weak eye. This helps change the eye’s refraction and can aid remove the cost of surgery. The earlier you start, the much better it will be for you in the future.

Computer games are being used by researchers to help treat the condition of amblyopia, or a ‘lazy eye’ as it is colloquially known, reports the BBC. Successfully navigating the specially developed games will automatically strengthen the gamer’s ‘weak’ eye.
Because one eye works better than the other, the traditional approach is to strengthen the ‘lazy’ eye by forcing its use, for example by wearing a patch over the good eye. Untreated, the good eye will simply become stronger and the weak one progressively weaker.
The University of Nottingham, however, has been carrying out research into using computer games that will force the use of the weak eye, aiding the recovery of a balance of vision. The system they use is known as ‘Interactive Binocular Treatment for amblyopia’.
Apparently, in one experiment – which uses a racing game (pictured) – the player sees his own car with the amblyopic eye and the rival cars with the good eye. Navigation of the track requires processing of obstacle by both eyes, alternatively.
The researchers say that the game was designed such that two viewpoints were completely different but complementary, with each eye seeing images that built up the full, final image.
‘Traditionally VR has been used to present realistic environments in 3D so you imagine you’re there because of the depth of the world around you,’ it quotes Dr Richard Eastgate of the university’s Virtual Reality Applications Research Team.
By contrast, his team is using VR to make something unrealistic – ‘virtual unreality’, he dubs it. ‘We’re actually presenting two different versions of the world to each eye.’
It seems the results have been positive, so far. ‘We thought we’d develop a system that needed about 400 hours of treatment like patching. In the end we achieved the same effect in an hour,’ the BBC quotes Dr Eastgate.
You can hear the full story as a BBC podcast, taken from the Digital Planet on the BBC World Service.
When it comes to their children, parents are always going to want the best for them. Whether that means success in everything life has to offer or overall health and well-being, we want our kids to be happy, healthy and, well, perfect! There is no denying that many children today suffer from poor vision, as well as eyestrain. But what can you do to help your children – are eyeglasses or contacts really the only viable solution to correct a child’s vision? While contacts and glasses are certainly a safe way to ensure your child can see properly, neither of these products really fix the root of the vision problem.
Did you know that 35 percent of children ages 13-16 need prescription glasses or lenses? Unfortunately, contacts and glasses can’t prevent your (or your child’s) eyes from growing weaker over time, which only results in needing stronger corrective lenses. But, there is another option! Eye exercises are a great way to help children build and maintain strong eyesight naturally, without the use of contacts or glasses.
Why Eye Exercises?
Parents often encourage their children to do strengthening exercises for their other muscles, especially when children play sports. However, they often neglect to remind their children to take care of their eyes! Eye exercises are a safe way to do just that. They are also designed to strengthen the eye over time, improving vision instead of just placing a lens in front of a damaged eye. A lens, whether it is in the form of glasses or contacts, will do nothing to help improve your child’s vision. You simply can’t correct the source of the problem with lenses.
Performing eye exercises is also easy and fast. Even young children can be taught to use basic eye exercises to improve their vision. Eye exercises are ideal for children of all ages because teaching kids to strengthen their eyesight early on will benefit them as they grow older – the longer they can avoid corrective eyeglasses and contacts, the better!
Eye Exercises for Kids
Below are some really easy eye exercises you can teach your children. Be sure to help them understand the importance of caring for their eyes. Also, make sure you supervise your kids until you are sure they can handle the eye exercises on their own!
Memory games: These kinds of exercises can be located online and are especially fun for children. The purpose of these games is to increase your child’s visual memory. In most games of this nature, a picture is shown briefly, and then the participant must try to remember as much about the picture as possible. The more you can recall, the better! You can also recreate this type of exercise with your own pictures or by playing memory board games.
Eye shift exercise: It is really important for children to learn to shift their eyes quickly between objects at different distances. One exercise to help with shifting vision involves a pencil and a calendar. Place a calendar on the wall and have your child stand at least 10 feet away while holding a pencil vertically in front of his/her face.
Instruct your child to focus on the pencil, and then to look at the numbers on the calendar. Then, have the child look back at the pencil. Repeat this at least 10 times. You can also change the amount of distance between your child and the calendar.
Tracking exercises: These exercises are great for kids because they help the eye keep track of words while reading. Kids who struggle with skipping over words, switching up the order of letters, and losing their spot while reading a text may be suffering from dyslexia in addition to having poor vision. They will benefit from this by doing the exercise regularly.
To do this exercise, hook a ball to some string or a shoelace. Hang the ball so that it is even with your child’s nose. Then, ask him/her to watch the ball as you swing it back and forth. Repeat this exercise while swinging the ball side to side. Your child should be following the movement of the ball with his/her eyes only – no head movements! This will strengthen the same muscles your child needs to do their reading at school and throughout their lives, so it’s really a great tool.
Rotating exercise: This one is really simple! Instruct your child to rotate his/her eyes in a clockwise motion. After completing one full circle, your child should blink and then proceed to rotate his/her eyes in a counter-clockwise motion. Repeat several times, making sure they are blinking in between.
Eye “writing” exercise: For this exercise, have you child face an empty wall, preferably not one that is a bright color. Tell them to write something, anything, with their eyes only. Do not let your child move his/her head to do this. Moving just the eyes in the shape of many different letters can really strengthen the eye muscles. It’s also a more entertaining exercise for children!
“Clock” exercise: To begin this activity, first tell your child to imagine a large clock. Have them look at where the center of the clock would be to start. Then, say a number and ask your child to look where it would be on the clock. Finish by looking back at the center. Repeat this at least 10 times and remember to instruct your child to use his/her eyes only!
After teaching your child the simple exercises above, you can also check out our other free eye exercises and our Ocu-Plus Formula. With your assistance, your child can greatly benefit from a daily eye vitamin like this.
Ocu-Plus contains 17 vitamins we recommend taking to support eye health. However, please keep in mind you should consult with your child’s doctor before starting him/her on a vitamin. Just make sure your children are getting all the necessary vision-boosting nutrients – a good diet coupled with these eye exercises will help your child enjoy the benefits of naturally healthier eyes!
Our Rebuild Your Vision Ocu-Plus Formula Contains All 17 Vitamins, Minerals, and Herbal Supplements to Improve Your Eye Health!
Lazy eye or amblyopia may be caused if a young child needs very strong glasses, has one eye that is significantly more short-sighted or long-sighted than the other, or has a squint (where the eyes are not looking in the same direction). This means that the sight in the affected eye or eyes does not develop properly.
Who is affected by amblyopia (lazy eye)?
About 2%-3% of all children develop lazy eye, clinically known as amblyopia, when they are a few years old. Children with learning difficulties are ten times more likely to have problems with their vision, including amblyopia
What are the symptoms of amblyopia (lazy eye)?
Lazy eye is not always easy for parents to spot, and children assume that the way they see is normal and so will not tell you that there is a problem. Symptoms include:
- one eye turning in or out. This may be more noticeable if the child is tired or unwell
- being clumsy or having poor hand to eye coordination
- screwing up their eyes or shutting an eye
- complaining about double vision, or having unexplained headaches.
The NHS recommends that all children should have vision screening during their first year at school. This is done in school, usually by a school nurse, and should pick up vision problems including amblyopia. If your child misses the school screening, you should take them to your local optometrist for a sight test. This will be paid for by the NHS.
How do you treat amblyopia (lazy eye)?
It is more difficult to treat lazy eye once the eyesight has finished developing (usually around the age of seven), but it may still be possible to significantly improve the vision in the weaker eye. The aim of treatment is to stimulate the vision to develop in the lazy eye by enabling the child to use the eye more. The treatment depends on what is causing the lazy eye:
- wearing glasses – if the cause of the amblyopia is fully corrected by glasses, the vision in the amblyopic eye may improve over time simply by the child wearing glasses, and no further treatment is needed
- patching – covering your child’s good eye can encourage them to use the lazy eye, and so improve vision in that eye
- eye drops – these are put into the good eye to blur the vision in that eye. They act like patching.
- surgery – if glasses do not fully correct a child’s squint, the child may need an operation to straighten their eyes to help them use both together. This can be done as early as a few months of age.
It’s among the most common questions asked at Laser Eye Surgery clinics: Are you able to treat and improve amblyopia? Or as it’s more commonly known as, lazy eye.
Amblyopia is the most common cause of visual impairment among children, affecting around two to three in every hundred.
Unless caught early and treated during childhood, the condition persists into adulthood. This is often difficult, and thus amblyopia is the most common monocular (one eye) impairment among young and middle-aged adults.
Expert surgeon Mr Glenn Carp on treating lazy eye with Laser Eye Surgery
In the video below Mr Glenn Carp answers the question: Can Laser Eye Surgery treat amblyopia?
As Mr Carp explains, the condition is caused when a child has had some obstruction to their vision. This may be in the form of a refractive error, which was not treated with glasses, an injury, or another condition like cataracts.
As a result of the blockage to the vision, the eye only learns to see to a certain point. And as around the age of 7 certain pathways that link the eye to the brain finish their development, if the full vision stimulation is not achieved before this point, the eye remains underdeveloped.
Therefore, Laser Eye Surgery is only able to refine the vision in an amblyopic eye to the level it can achieve with a glasses prescription. That goes to say, Laser Eye Surgery is unfortunately not able to refine the vision further, due to the underdeveloped pathways from when the child was very young.
But am I still suitable for Laser Eye Surgery?
While Laser Eye Surgery cannot specifically treat lazy eye, suitability for Laser Eye Surgery depends on the best corrected visual acuity of the lazy eye. Many patients with mild lazy eyes have had successful outcomes after Laser Eye Surgery.

Amblyopia develops in childhood and results in reduced vision in one eye.
Amblyopia develops in childhood and results in reduced vision in one eye.
What is amblyopia?
Amblyopia happens when one eye is used less than the other from birth to seven years of age, which leads the brain to prefer the better eye. Rarely, as a result of a strong glasses prescription, amblyopia may affect both eyes.
What causes amblyopia?
Amblyopia can be caused by:
- A turn in the eye (a strabismus or squint)
- A difference in the glasses prescription between the two eyes
- An obstacle blocking visual stimulation to the eye, such as a droopy eyelid or cataract (cloudy lens); the amblyopia might persist even after the obstacle has been removed
Treatment for amblyopia
Glasses can help and should be worn full-time. A patch covering the good eye will stimulate the weaker eye. The length of time the patch needs to be worn depends on how bad the vision is and on the age of the child. If glasses are worn, the patch should be worn under the glasses, but sometimes, when the vision has started to improve, the patch can be worn on the glasses. In some cases, particularly if the child cannot wear a patch, special eye drops can be used to blur the vision in the good eye.
Most cases of amblyopia are treatable. However, the success of treatment is dependent on the initial level of vision your child has in the bad eye, their age and the level of co-operation with treatment. It is very important to detect and treat amblyopia as early as possible to get the best possible vision. If it is not treated, the vision in that eye will be permanently impaired, so it very important that you try really hard to follow the instructions given by your child’s doctor or orthoptist.
We know that children do not always understand why they need to cover their good eye and treatment can be difficult. Give lots of praise when the patch is worn well and be ready to distract your child’s attention to prevent the patch being pulled off. Your orthoptist is very experienced in dealing with children who have amblyopia and can advise you about carrying out the treatment at home as effectively as possible.
Amblyopia is most successfully treated before seven years of age. After this, the eyes and brain become too mature to change. Later attempts to treat are difficult and might not be successful.
A US team from the Children’s Hospital of Pittsburgh found treatment improved the vision of many older children with the condition known as amblyopia.
Patching the good eye made the muscles of the lazy eye work harder and improved sharpness of vision.
But it is not yet known whether the benefit will be long-lasting, the authors told Archives of Ophthalmology.
They plan to follow the patients into adulthood to find out.
Conventionally, children with amblyopia are treated in their pre-school years. The upper limit for successful treatment has generally been thought to be about nine or 10 years of age.
Dr Richard Hertle and colleagues from the Pediatric Eye Disease Investigator Group recruited 507 children with amblyopia aged between seven and 17 to take part in their study.
All of the children were given glasses if they needed them.
The children were randomly divided so that half would be given treatment for their amblyopia.
This involved wearing a patch over the “good” eye for between two and six hours a day plus activities to make them use their near vision, such as playing computer games or reading.
The researchers followed up all of the children every six weeks for a total of 24 weeks to see how they had responded.
Of the children aged seven to 12, half in the amblyopia treatment group had better sharpness of vision during follow up compared with only a quarter of the children who were given glasses alone if needed.
Of the 13- to 17-year-olds, about a quarter in both the amblyopia treatment group and in the control group had better sharpness of vision during follow up. However, half of the teenagers who had not previously been treated for amblyopia when younger responded to the amblyopia treatment in the trial.
Co-researcher Dr Mitchell Scheiman said: “This shows that age alone should not be used as a factor to decide whether or not to treat a child for amblyopia.
“The opportunity to treat amblyopia does not end with the pre-school years.”
Mr John Sloper, consultant at Moorfields Eye Hospital in London, said: “We have always been aware that there are some children who will respond to treatment past the conventional cut off age.
“What this has done is give us a better handle on how many and how well they respond.”
He said it was important to pick up and treat cases early to achieve the best outcomes.
Mr Nick Astbury, president of the Royal College of Ophthalmologists, echoed this advice, saying: “Patch as early as you possibly can.”
