Lazy Eye Crossed eyes, wall eyes, and lazy eye are all conditions that prevent both eyes from pointing straight ahead when focusing on the same object at the same time. The medical term for these conditions is strabismus.
Crossed eyes happen when one eye turns inward.
With wall-eyes, one eye turns outward. With lazy eye, one eye always focuses straight and the other wanders. You may hear lazy eye referred to as amblyopia. All three of these conditions are common among children and run in families. In rare cases, blindness results from untreated lazy eye.
