Cataract- An eye disorder

Cataract- an eye disorder caused due to clouding of the lens. This clouding of lens is very slow and forms gradually due to this it is difficult to know the signs and symptoms. Due to clouding of lens the light rays cannot pass through and cannot focus on retina, if rays are not focused than there is no image formation in the brain and thus visual perception is partially or completely lost.
