Based on your answers it is unlikely that you have convergence insufficiency. Convergence insufficiency (CI) is a medical condition in which a person’s eyes are unable to work together while focusing on nearby objects. When you look at an object nearby, your eyes must move and point inward to create a single, focused image. These synchronized eye movements are called convergence. In people with convergence insufficiency, one of their eyes turns outward instead of converging toward the center. People with CI often have blurred or double vision or have to close one eye while reading to see clearly. CI affects about 13 percent of all school-age students.

A diagnosis is based on your medical history, an eye examination and specialized CI evaluation tests.
