کور رنگی چیست ؟

Cones are small structures in the retina of the eye. They contain pigments which you

need to be able to see colors. Color-blindness is not a great handicap. But in some

jobs,like that of an airline pilot, it is very important to be see different colors quickly.

Many color-blind people have difficulty in distinguishing between red and green traffic

lights.

This can lead to serious road accidents. Most people who suffer from color blindness are

male. We do not quite know why.
