Cataract

About

Cataract is the clouding of the natural lens of the eye. The lens forms part of the focusing mechanism of the eye and is usually transparent in young age. In a normal eye, this lens is clear. It helps focus light rays on to the back of the eye, the retina, which sends messages to the brain allowing us to see. When the lens becomes cloudy and prevents the light rays from passing to the retina the condition is called cataract.
