Cataract is a condition of eye when:
The correct option is D all of the above
Cataracts occur when there are changes in the
lens of the eye causing it to become less transparent. The lens is the
crystalline structure that sits just behind your pupil, which is the black
circle in the center of your eye.When light enters your eye, it passes
through the transparent layer of tissue at the front of the eye called
cornea and the lens, which focuses it on the light-sensitive layer of cells at
the back of your eye called retina.
Cataracts start to develop in a person's lens
as they get older age related cataracts, stopping some of the light
reaching the retina and affect your vision, making it become increasingly
cloudy, blurry, or misty.
So Cataracts can occur when person eye sight become foggy, or lens
becomes cloudy and when there is loss of vision.
