Medical Definition of Lazy eye. Lazy eye: An eye that diverges in gaze. A lazy eye is formally called strabismus. A lazy eye (strabismus) can be due to esotropia (cross-eyed) or to exotropia (wall-eyed). The danger of the condition is that the brain comes in time to rely more on one eye than the other and that part of the brain circuitry connected to the less-favored eye fails to develop properly, leading to amblyopia (blindness) in that eye.
amblyopia. more commonly called lazy eye and occurs when a child does not use one eye regularly. a child with this disorder does not have normal depth perception and often also has concurrent strabismus, a condition in which the eyes do not focus in unison.
