Color Blindness
A vision problem in which a person has difficulty distinguishing specific colors—most commonly red and green, but sometimes blue and green or blue and yellow. Color blindness is not a form of blindness but rather a deficiency in color perception. It usually affects both eyes and is much more common in males than females. There is no treatment or cure for this problem, but a color-blind person can learn to adapt in various ways. For example, a color-blind driver can remember that the light positioned at the top of a traffic light is red. It is beneficial to diagnose color blindness in children at an early age so that steps can be taken to avoid learning problems related to color perception.
