What is amblyopia?
Amblyopia, commonly known as lazy eye, is a condition where vision in one of the eyes is reduced because the eye and the brain are not working together properly. The visual loss in amblyopia cannot be corrected by just wearing glasses. Amblyopia is the most common cause of visual impairment during childhood. The condition affects approximately 2 to 3 out of every 100 children. It is thought to develop early in life during the critical period of visual development. Unless it is successfully treated in early childhood, amblyopia usually persists into adulthood, and is the most common cause of monocular (one eye) visual impairment among children and young and middle-aged adults.
