Color Blindness



The color blindness is aimed at revealing color perception deficiencies. It affects a significantly high number of population, mostly men. Color blindness (color vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. While color blindness is not a treated issue, modern ophthalmology offers a set of coping mechanisms for individuals suffering from this issue. The color vision test is based on the Ishihara Color Vision Test. It is a red-green color vision deficiency test that will help to reveal color blindness.
