Convergence Insufficiency (CI) is an eye teaming problem for near visual tasks such as reading or computer work. It is characterized by the eyes inability to converge (or point both eyes toward the near task) and maintain a clear, single image. It manifests as headaches, eye fatigue, poor concentration and print that moves, looks shadowed or is double. CI can be found in both children and adults and can be the cause of children being diagnosed with ADD or ADHD. Convergence insufficiency will not go away on its own. Instead, the individual learns avoidance, or compensating behaviors such as covering an eye. The most effective and consistent treatment is office-based vision therapy to train the eye teaming. This was demonstrated by a 2008 National Eye Institute Study which compared various treatment approaches.

Our patients have experienced dramatic changes in work performance, and school performance following therapy for convergence insufficiency.
