Convergence is the coordinated movement and focus of our two eyes inward on close objects, including phones, tablets, computers, and books.
Convergence is one of many Vital Visual Skills learned during our early years, and Convergence Insufficiency is a common problem with the development of these skills. When convergernce is insufficient, it means that the eyes do not come together closely enough when looking at a near object, so the eyes are essentially looking "past" the target focal point.
When we are not able to converge our eyes easily and accurately, problems may develop, such as:
Eye coordination problems like convergence insufficiency generally cannot be improved with eye glasses or surgery. A program of Vision Therapy may be needed to improve eye coordination abilities and reduce symptoms and discomfort when doing close work.
The American Optometric Association and the 2008 Convergence Insufficiency Treatment Trial clearly support the superiority of office-based vision therapy, supplemented by at-home vision therapy, for treatment of convergence insufficiency.

The Convergence Insufficiency Treatment Trial - Attention and Reading Trial (CITT-ART) Study is a currently ongoing study designed to determine whether office-based vision therapy improves reading and attention in children who have symptomatic convergence insufficiency.
