Color blindness (sometimes spelled colour-blindness; also called race blindness) is a sociological term for the disregard of racial characteristics when selecting which individuals will participate in some activity or receive some service.
Fortunately, you have to worry no more as a website called color-blindness.com help you take a glimpse. People have this belief that the color-blindness individuals see the world only in two colors: black and white. That is a myth, and research shows that about 99% of the so-called colorblind people can see different colors. Because of this statistics, color blindness is not used to refer to those individuals on professional grounds. âColor Vision Deficiencyâ (CVD) has often been used as it is more accurate than the general âcolorblindness.â The statistics given by the color-blindness.com show that about 0.5% of women population (1 in 20) and 8% of men (1 in 12) are victims of color vision deficiency. CVD takes various forms which include Deuteranomalia (which makes the affected population to see things as a little bit fade), Protanopia (which makes things appear greenish), and Tritanopia (which is a greenish-pink vision).
