What is amblyopia?

Turning off vision: The human brain utilized the input of both eyes to aid in depth perception/distance etc. As a child grows, their eyes may have different strength, or weakness in an eye muscle may allow one to line up wrong. The fuzzy or double vision confuses the brain. Over time the brain may begin turning off the input of one eye & keep the best. That process is called amblyopia. If caught early it can be fixed.

Impaired vision: In children, when the nerve pathways between the eye and the brain are developing, there needs to be two clear images (one from each eye) for appropriate development of vision and depth perception. If one image is abnormal (e.g. Vision is blocked or blurred) or the eyes are misaligned producing double vision, then as a coping mechanism, the abnormal image will be suppressed and vision impaired.
