Is it true that a wandering eye is a lazy eye?

Not necessarily: The short answer is no.An eye may drift out of alignment transiently as part of a nerve palsy or muscle weakness.If alignment is re-established (palsy resolves or surgery), vision may be retained.If alignment provides a blurry or double image for too long, the brain will turn of one image in favor of a clear picture.This turning off produces amblyopia (lazy eye), the wondering eye would be affected.
