Amblyopia is an early childhood condition, where the vision does not develop properly. It usually occurs in one eye, but it can occur in both. Sometimes referred to as lazy eye, amblyopia affects about 1 in 25 children.
Amblyopia is not due to a disease of the eye but is the name given to describe poor vision which does not improve by wearing glasses. It occurs when normal visual development is prevented or disrupted in early childhood.
