Convergence Insufficiency

Convergence insufficiency is an inability or decreased ability to converge the eyes when focusing on a near object. Individuals with convergence insufficiency have problems maintaining binocular vision when looking at near, which affects their everyday activities such as writing and reading. While the number of people with convergence problems is far from small (up to 15%!), we still don’t completely understand why convergence insufficiency ensues.


Treatment of convergence insufficiency

The history of convergence insufficiency treatment is more than 150 years old but nowadays the most prevalent and important treatment option are orthoptic exercises. These exercises, such as pencil push-up, can all be performed at home yet they might not engage the patient enough. For this reason, several computer or tablet-based software therapy solutions were developed, through which a person can conduct vision therapy in a guided virtual environment.


It’s a vision therapy for convergence insufficiency!

AmblyoPlay® is a vision therapy solution that is performed through playing therapeutic games and exercises on your tablet or computer for 30 minutes per day. With exercises that adapt to each patient and their specific needs, it is ideal solution for problems such as lazy eye, strabismus, convergence insufficiency, double vision or other binocular problems.

Vision Therapy

Perfect for patients of all ages above 3 years. Yes, it works for adults, too!

Visual skills

Helps improve all 6 core visual skills required for treatment of broad range of problems.


Makes vision therapy fun and engaging with games and rewards.

AmblyoPlay works for patients above the age of 3 years – and yes, it does work for adults as well, just the speed of improvement diminishes with age.

It has been successfully used to treat the following problems:

    • amblyopia or lazy eye (all forms, including bilateral)
    • strabismus
      • exotropia
      • esotropia
      • intermittent esotropia and exotropia
    • convergence problems
    • divergence problems
    • focusing problems
    • diplopia or double vision
    • eye-teaming
    • eye movement dysfunctions
    • tracking problems
    • saccadic movements
    • accommodative dysfunction

While it is an extensive list, it is not exclusive. AmblyoPlay can help with other problems and please do reach out if you’re not sure if it is for you at [email protected]!

Improving 6 core visual skills

AmblyoPlay® is used by patients worldwide to treat a wide range of visual dysfunctions, such as lazy eye, strabismus, convergence insufficiency, double vision, and many others. We are able to tackle such a broad range of problems by improving 6 core visual skills. When we improve these core skills, we also improve our vision as a whole.

An inability or decreased ability to converge the eyes whilst focusing on a near object is described as convergence insufficiency. Those who suffer from convergence insufficiency cannot properly maintain binocular vision when focusing on the near objects. This is of great importance especially when writing or reading.

alleviate the discomfort and eyestrain during reading or writing
or any kind of near activities, patients often close one eye when performing
them. Thus, they ameliorate the symptoms of improper binocular fusion, which include:

The connection between Strabismus and Convergence Insufficiency

Roughly 10-20 percent of those who have strabismus, also experience convergence insufficiency of some degree. Considering that about 1-3 percent of people experience strabismus, the burden of convergence insufficiency in population is not at all that small. There is a lot of debate about why convergence insufficiency ensues, and the truth is that we still do not know precisely.

Orthoptic exercises are the way to go

More than
150 years ago the first treatment for convergence insufficiency was proposed,
and since then many different treatment options, the most important being orthoptic
, have been suggested.

 Generally, treatment options include home-based exercises, some special in-office exercises, and newly developed computer program-based training. One of the most commonly used home-based exercise to tackle convergence insufficiency is pencil push-up. Whilst slowly moving the tip of the pencil towards their nose the patient tries to maintain binocular single vision, thus better their convergence abilities. The studies have shown that simple pencil push-ups can be as effective as much more complex and pricier in-office exercises if they are performed correctly and frequently enough.

The problem is that especially younger children often find such exercises extremely boring, leading to compliance issues. For those exercises such as convergence cards, stereograms and computer-based convergence exercises were introduced. Especially computer-based convergence exercises are becoming more and more popular as they enable much greater involvement and are therefore much more interesting and entertaining for younger children.

In some very refractory and rare cases, surgery might be the last resort option, although it is rarely used due to the high risk of inducing diplopia at distance after surgery. Convergence insufficiency is more often than not solved using exercises and training that we briefly touched upon in this article.

Luckily, as boring as convergence insufficiency exercises may be, they are extremely effective, as it is believed that the success rate is about 80%. Frequent follow-up visits combined with good compliance to prescribed convergence exercises should bring the results, everyone, wishes for.

AmblyoPlay against convergence insufficiency

AmblyoPlay is a gamified vision therapy that helps with convergence insufficiency by using dichoptic vision therapy. As we split the image that each eye receives while maintaining focal points, we engage the brain to start creating a single image. It can be used at home on your devices and only requires active subscription and AmblyoPlay Box. You can check your options HERE!
