What Is Cataract?

In cataract, the natural lens of the eye (which lies behind pupil and iris) gets clouded. The lens is part of the eye, which helps to focus an image or light on the retina. In a normal eye, light passes through the transparent lens to the retina, where the light gets changed into nerve signals, which are sent to the brain. In order to receive a sharp image by the retina, the lens must be clear. If there is a cataract, the image formed is blurred. A cataract develops over the long period of time. The best way is to wait and watch, till it develops fully. Surgery is the most common treatment of cataract.

It occurs mostly in people above 40 years of age and is a main cause of blindness worldwide.
