The eyes do not converge adequately for close vision when there is convergence insufficiency. When we read, our binocular function both eyes working together is compromised. While reading, one or both eyes may tilt outward. This makes it challenging to read or use a computer.

Convergence insufficiency can occur in anyone, but children and young people are particularly likely to experience it.

While reading or performing other close work, people get symptoms. They include headaches, blurry vision while reading, squinting or closing one eye while reading, words that seem to move or float on the page, eyestrain or fatigue, and double vision (diplopia) (asthenopia)

Patients may be affected by one or more of the symptoms, which can vary. Reading while taking breaks to rest your eyes can lessen symptoms of eye strain, fatigue, and other problems.

The cause of this condition is not fully known. The muscles and nerves that regulate eye movement are believed to be weak.

It is more common in people who have a family history of convergence insufficiency.

Convergence insufficiency that develops later in life is known as acquired, and it can be brought on by brain diseases, eye injuries, and autoimmune diseases that damage the eye muscles.

Learning disabilities may also be present in some of these children. But it is crucial to remember that eye issues like convergence insufficiency or others do not contribute to learning disabilities. Problems with information processing in the brain are the root cause of learning disabilities.

Convergence insufficiency is treated with exercises that improve convergence.

Your orthopedist or ophthalmologist may advise exercises to be done in-office, at home, or both. Additionally, there are computer-based workouts. The most effective method can be decided by you and your doctor. You will receive the exercise supplies and instructions from them.

However, exercises are not recommended for all patients with this condition.

Eye exercises successfully treat the symptoms of convergence insufficiency in about 70 percent (7 out of 10) of patients. Convergence insufficiency might recur occasionally even after receiving effective exercise therapy. Resuming the eye exercises could help the symptoms disappear again.

Other treatments include prism-coated eyewear to lessen double vision and, in rare instances, surgery to strengthen the eye muscles.
