Slide3Slide4Causes In World War II, scientists discovered that analysis of color aerial photos gave more information if at least one team member was color blind. Humans are the only
trichromatic primates with such a high percentage in color blindness. Color blind people see different patterns, colors, and sometimes don’t see colors at all. Types There are many types of color blindness. The most common type of color blindness is red-green. You can get red-green color blindness from injuries to the retina, optic nerve, or higher brain areas. Another type of color blindness is that only part of the visual field is normal and the other part is a type of color blindness.
Cures
Color blindness cannot be cured
Slide5Slide6Color blindness is not a form of blindness at all, but a deficiency in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as blue and yellow or red and green.
Red-green color deficiency is the most common form of color blindness, affecting about 2 percent to 6 percent of all men because of the way the trait is inherited.*Much more rarely, a person may inherit a trait that reduces the ability to see blue and yellow hues. This blue-yellow color deficiency usually affects men and women equally.
