Convergence Insufficiency occurs when your eyes do not properly align while focusing on a near object. When you read or look at a close object, your eyes should converge — turn inward together to align—resulting in a single image. Those who suffer from Convergence Insufficiency can experience double vision, strain, fatigue and poor reading comprehension. This is a common problem in children who have reading difficulty in school and adults who find themselves transposing numbers. Vision therapy can greatly alleviate the symptoms that patients experience and can lead to more success in school, work and everyday life.
