are many causes and the most common cause is aging of the eye that leads to hardening and clouding of the lens. Children and new-born babies can also develop cataract due to hereditary disorders, metabolic diseases or congenital infection. A hard blow, puncture, cut or chemical burn to the eye can damage the lens resulting in traumatic cataract. Certain infections or diseases of the eye, such as diabetes, as well as some medications, such as steroids, can also cause cataract.
