Convergence insufficiency occurs when your eyes don't work together while you're trying to focus on a nearby object. When you read or look at a close object, your eyes need to turn inward together (converge) to focus. This gives you binocular vision, enabling you to see a single image.

Convergence insufficiency can cause difficulty with reading. This may make parents or teachers suspect that a child has a learning disability, instead of an eye disorder.

Treatments for convergence insufficiency are usually effective.
