READ THE PASSAGE BELOW : 10 X 1 = 10 M
Cataract is the major cause of blindness, which is also caused by a damage to the
cornea. It occurs more often in old age. As one starts growing old, the lens of the
eye hardens, loses its transparency and becomes opaque. It obstructs the light
rays from entering the eye.
The onset of cataract blurs the vision. Sometimes, the cataract patient sees
multiple images instead of a single object image. Because of the gradual
development of Cataract, the afflicted person loses his/her vision and the world
becomes dark to him/her.
The development of cataract is a complex process. However, the following factors
can be attributed to its formation. Cataract generally develops in old age but
sometimes, children are born with cataract because of hereditary defect. Eye
injuries too, can cause cataract.
People exposed to sunrays for longer periods develop cataract earlier than others.
Researchers opine that the smoke inhaled while smoking, carries substances
internally damaging the eyes.
Ultraviolet radiation, invisible to the human eye, is linked to skin cancer. The
victim loses vision and the world becomes dark to him.
