Color Blindness Chart

A Color Blindness Chart is the most simple and accurate method of identifying congenital color blindness in two forms – total color blindness and red-green blindness, complete as well as incomplete. The term ‘color blindness’ refers to the condition, whereby some of the colors cannot be distinguished mainly because of hereditary factors. The chart has different color combinations simulated with varied kinds of color blindness, such that the colors can though be read by a person with normal color vision but not by one with defective color vision. Males are said to experience it at the rate of 12 out of 100, and females at a rate of 1 out of 200.
