What is Convergence Insufficiency (CI)?

Convergence is the coordinated movement and focus of our two eyes inward on close objects, including phones, tablets, computers, and books. Convergence skills are learned during our early years, and Convergence Insufficiency is a common problem with the development of these skills.

When we are not able to converge our eyes easily and accurately, problems may develop, such as:

• Eye strain
• Headaches
• Double vision
• Difficulty reading and concentrating
• Avoidance of near work
• Poor sports performance
• Dizziness or motion sickness

Treatment of Convergence Insufficiency

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.
