Cataract leads to cloudyness in the lens of eyes which causes decrease in eye vision. Due to catarct, light cannot easily pass through retina which causes blurred vision. It often develops slowly. Protein or yellow brown pigment gets deposited in the lens. Cataract is the cause of nearly half of the blindness. It occurs mostly due to aging or sometimes due to trauma or exposure to radiation.
