How do people who are colorblind really see
Color blindness, or color vision deficiency, in humans is the inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. Color blindness affects significantly much more males than females (about 20 times more in percentages)
