How to Fix a Lazy Eye: It CAN Be Done


How to Fix a Lazy EyeIf 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.

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 2014 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.”

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.  


Video Gaming Being Used to Treat “Lazy Eye”:  A trend we noticed over the past year is using 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.

My left has always had weaker vision than my right eye for as long as I can remember. Both of my eyes have been even, they stay in the same place. But now that I am 16 years old my left eye keeps wondering if I stare to long at something. I was wondering what can I do to not end up having strabismus?
Posted @ Thursday, April 05, 2012 10:33 PM by Breille
If your eye truly is 'wandering' or 'turning out' while the other eye remains straight, then strabismus is already present because the eyes are not aligned under normal binocular viewing conditions. The next step is to have your vision evaluated by a behavioral or developmental optometrist who may recommend vision therapy for the strabismus.

my left eye recently started to become a little droopy. I notice when i look at someone i feel i need to focus into one eye and have to think about looking and am not just seeing. like i often feel like I need to blink and stare at one eye. Do I have the same problem? Or could it be something else?

I am a 36 year old female and I am convinced my right eye is ever slightly lazy, in that it is off center, closer to the outer half than center. It bothers me when I look in the mirror applying my face lotions and makeup and it somehow "ruins" my face. I am a definite noticer of lazy, off centered eyes in other people and it can be a bit distracting looking at them and it certainly is bothersome to me to have to look at my face in the mirror. I do have prescription glasses but only for night driving in unfamiliar places or when I have to see something that is a far distance. I wish there was a nonsurgical, and permanent way to fix my lazy eye.

I'm 27 years old and have an lazy right eye. I'm mainly using my left eye, but when I covered the left eye, all I only see is blurry, can't read and can't see anything. The last time I went to the eye doctor was in 1999 when I first came in the U.S.A. Now, i wanted to know is there a really treatment or cure for it? I'm staying in Baton Rouge, L.A. I am currently 2nd year medical student and always have a dream to see with both eyes. With both eyes, it is better for me to read, and study better. More importantly, when I have to deal with microscopically. If anyone has any information please help and guide me. Thank you in advance.

Hello everyone. I had a lazy eye as a child (not born with one but was caused by an illness when I was an infant). I was told to have surgery and this was about 25 years ago. Glad my parents didn't listen to the first opinion. Surgery would not have fixed it. I did as the article stated have physical therapy just like any part of your body if the muscle is weak. My eye would just wonder off and do it's own thing.. I had the stronger eye patched and had many other series of visual activities that I had to do daily for almost three years. It was tough (long term commitment as a child) but it worked. I am a living testimony that visual activity/therapy works. 25 plus years later and I have total control of my lazy eye. After I completed the therapy I have never had an issue with my eye again.
Posted @ Thursday, March 21, 2013 11:19 AM by Mmartin
My eye always feels lighterthan the other and it's extremely aggravating it affects my vision so bad I cant sit and watch tv without it attracting another sight. I have to close one eye to even be satisfied at myself, I never look at someone with both eyes open because I fear of bein made fun of. I was going to get it fixed but days later the government cut me of my check and now I don't have no way of payin for it. I've tried getting a job but people think i'm retarted because of my eye.

i have had a lazy eye all my life, it was first noticed when i was 2 because my eye "wondered off" as my parents would say. i went to the eye doctor the next day and told my parents to patch over my good eye. which they did as they where instructed, and for some reason i had to patch my other eye after some amount of time.(i was very young im not sure how long) but i had to wear the eye patch from the age of 2 till i was 9. after that they said i had "aged out" and this was as good as it was going to get. i got to the eye doctor regularly (once a year) and my vision seems to be fading in my lazy eye. i am now 20 and was just wondering if all the patching and constant prescription changes where done right?(from what i have said in this comment) or was all the years spent trying a failure? and was looking into getting lasik and was wondering with this condition is lasik just a waste of money?

I have had a lazy eye for 28 years now( it runs in my family). When I was a teen I read many books and there was one that taught me to train my eye. It work but sometime it still wanders. I wear contacts and its doesn't work the rude doctor told me it can't be fix. I don't believe her. Do I have to have surgery? Or can I train my eye?

Hello my name is Soren. I have had a lazy eye for as long as I can remember. It always bugged me when I was in middle school and high school and people would ask me what I was looking at. Especially cause I was trying to look at them but I guess my eye must wander pretty badly. I had lasik eye surgery done about 2 years ago. I was wondering if there was anyway I could make my lazy eye not as noticable. It really bugs me that I don't want to look anyone in the eyes. 
Thanks in advance and by the way I am located around in the Omaha, Nebraska area so if there is anywhere you can tell me to go it would be greatly appreciated. 
I was glad to find this website and find out that I am not the only one.

Hi my left eye has been lazy (bad) my whole life..I've went to eye doctors and all of them tell me that I can't fix it because my brain has trained my eye to be like this...I've tried ignoring that I have a lazy eye and try to wear my hair over my eye to cover it but people still notice it.. is there a way I can fix it I am 22 years old I live in tiffin Ohio and being a cashier is hard because people judge only because of that
Posted @ Sunday, August 25, 2013 11:06 PM by Kathryn Shisler
Kathryn - If you're wearing your hair over your eye, it must mean that you have an eye turn, which is referred to as a strabismic eye. In any case, an amblyopic or strabismic eye can be treated, but we would need to examine you to see if we could help your particular case.

I am curious if you could tell me what could possibly be wrong with my eyes. I have been shrugged off by several eye doctors because of it. I always thought it was just a lazy eye, but I believe it has something to do with the muscles in my eyes. My right eye can look far to the left while the left one stays looking straight. I cannot look to the left at all with my left eye. I haven't found that one eye wanders or that it affects my depth perception or any of that, but I cant be sure because it has been like this for as long as I can remember.
