Color Blindness Definition & Overview

Definition

Color blindness usually affects a person’s ability to distinguish between shades of red and green or between shades of blue and yellow. Complete color blindness, which is very rare, causes a person to see most objects in shades of gray.

Color blindness occurs when light-sensing chemicals in the eye do not work properly.

If you suspect you have this condition, contact your doctor. Although most color blindness cannot be cured or treated, you can learn simple ways to manage your difficulty seeing color differences. Some cases of color blindness may indicate another illness that will require treatment.
