When is it too late to treat lazy eye?

Lazy eye or formally amblyopia is a disorder that arises in children within the critical period for the development of vision. This is, by definition, the first eight years of one’s life.

Humans are born with very poorly developed vision, which is very strongly influenced by visual input from the eyes in early life. In other words, the balanced input from the two eyes instructs proper development of parts of brain responsible for sight, hence vision.

If, for whatever reason, the visual input from the two eyes is unbalanced or diminished, amblyopia ensues. In this blog post, we will explore the question: When is it too late to treat lazy eye? and discuss options for amblyopia treatment for adults.

Amblyopia Meaning

Firstly, let’s briefly understand the nature of amblyopia. The condition arises due to a lack of visual stimulation during early childhood, often resulting from a misalignment of the eyes (strabismus) or a significant difference in refractive errors between the two eyes.

The Critical Period in Visual Development

During the critical period of visual development, the brain fails to process the signals from the affected eye adequately, leading to the suppression of its visual input.

The Optimal Treatment Window for Amblyopia: Can one Correct Lazy Eye in Adults?

Early diagnosis and treatment of amblyopia in childhood yield the best results. The brain’s plasticity during this crucial stage allows for effective interventions. The optimal period for amblyopia treatment lies within early childhood, ideally before the age of 8-10 years.

During this stage, the visual system is most receptive to intervention, and significant improvements in visual acuity can be achieved. However, it is essential to note that treatment effectiveness can vary. It depends on the severity of amblyopia, compliance with therapy, and individual factors.

When to Initiate Treatment for Lazy Eye?

Amblyopia is generally treated as soon as it is diagnosed, or at least it should be. Studies show that the sooner the treatment is initiated the better the outcome.

In certain cases, though, amblyopia itself cannot be addressed before the cause is removed, as for instance in cases of congenital cataract.

Indeed, any form of visual deprivation in early infancy usually results in very deep amblyopia that does not respond well to treatment unless the cause is removed in the first couple of months in one’s life.

In terms of age, then, if amblyopia treatment is initiated before the age of 8-10 years, a favorable outcome can be expected (apart from some severe individual cases). That said, there are reports that show that certain improvements can be possible even beyond the critical period for the development of vision and well into adulthood.

”Reports show that certain improvements can be possible even beyond the critical period.”

What Age is Too late to Treat Amblyopia?

It’s never too late! While it is preferable to initiate treatment during childhood, it is not necessarily “too late” to treat amblyopia in adulthood. The critical period for visual development may have passed, and the effectiveness of treatment might be diminished, but visual improvements can still be attained.

Treatment for Lazy Eye in Adults

Several treatment options can be considered for adults with amblyopia:

Vision Therapy

This comprehensive approach involves various exercises and activities designed to improve visual function and coordination. Vision therapy aims to retrain the brain and improve the connection between the affected eye and the visual system. Furthermore, it has been found as one of the most successful methods of treating amblyopia because it actively engages the visual system.


In cases where strabismus is the primary cause of amblyopia, surgical correction of the eye misalignment may be recommended. This procedure can help realign the eyes and improve the visual input to the brain.

Prism Glasses

Prism lenses can be prescribed to help align the eyes and reduce the suppression of the amblyopic eye. These specialized glasses can aid in achieving binocular vision and better visual integration.

What Happens without Treatment for Lazy Eye?

Will Lazy Eye in Adults Correct Itself?

Whether your amblyopia went undetected during childhood, or you acquired the condition in adulthood, the consequences of neglecting treatment for a lazy eye persist. If left untreated, it can lead to strabismus, problems with central vision, and blindness. Therefore, seek help as soon as you detect vision problems and right after you are diagnosed with amblyopia.

Can AmblyoPlay Treat Amblyopia in Adults?

Yes, it can. It is already being used by numerous adult patients. 30% of all our users are adults who are seeing great improvements from our home-based vision therapy. The methods that work for kids work just the same for adults, they only take a little longer.

On average, adult patients use AmblyoPlay for at least 12 months, which offers enough time both to achieve results, as well as to stabilize vision so that the problem won’t come back after stopping the treatment! Read the story about the 80-years-old user Dan.

80-years old user Dan

I have been very impressed with the design and implementation of AmblyoPlay. The navigation of the app is very intuitive. Even the music is appropriate, light-hearted, and pleasant.

While as an 80-year-old man, I am not an ideal candidate to benefit from AmblyoPlay, I have seen moderate improvement in my double vision that resulted from a surgical error during a cataract operation.

The response to questions and comments has been prompt and helpful. As a former software engineer, I really appreciate the professionalism of the organization that developed AmblyoPlay.

Lakewood, OH

Dave: ”I was skeptical…”

As a middle-aged man who had been told since childhood that there was basically nothing that could be done to help with my “lazy eye,” I was skeptical. Especially after constantly being told that this was even more so the case the older I get.

That being said, I wanted to give this a chance because anything that gave me some hope was worth the opportunity.

I wasn’t expecting drastic results considering my age. I knew that if this was going to have any effect, it was going to take some time. So, I definitely think I have a long way to go to truly be where I want things to be, but I have l, without question, noticed a difference and this product is the first thing in nearly 40 years to do that for me! Highly recommend anyone, of any age, give this a shot and at least see if it can help them.

Conclusion: Amblyopia Treatment for Adults

To sum up, treat amblyopia as soon as it is diagnosed. Do not give up on treatment even if you have missed the time period most guidelines define as best. When is it too late then? Although the optimal period for treating amblyopia lies within early childhood, it is never too late to pursue treatment options. While the potential for visual improvement decreases with age, adults with amblyopia can still benefit from various interventions.

As long as there is improvement with treatment, it is never too late, regardless of age. Indeed, there is an increasing number of success stories by patients in their 60s and 70s who are investing their time in vision therapy! It is crucial to consult with an eye care professional to determine the most suitable treatment plan based on your individual circumstances.

So, never give up trying! Remember, seeking treatment for amblyopia at any age can lead to improved visual.

Frequently Asked Questions

When is it too late to treat lazy eye?

No. It’s never too late. While it is preferable to initiate treatment during childhood, it is not necessarily “too late” to treat amblyopia in adulthood.

What happens if I do not treat lazy eye in adults?

If left untreated, it can lead to strabismus, problems with central vision, and blindness. Therefore, seek help as soon as you detect a vision problem and right after you are diagnosed with amblyopia.

Does AmblyoPlay work for adults?

Yes! AmblyoPlay works for adults just the same as it does for kids. The only difference is that the speed of improvements diminishes with age. This has to do with a process called brain plasticity, which means that the brain starts to get slower in rebuilding neurological connections as we age. However, over 25 % of all our users are adults, some of them even in their 50s and 60s!

Can lazy eye happen later in life?

Lazy eyes commonly develop in children. However, in some cases, conditions such as head trauma or eye injury can lead to the development of lazy eyes later in life.
