Color blindness is an abnormal color vision. The person with color blindness, called colorblind, is unable to distinguish certain colors, usually red and green.
In 1794, John Dalton published a scientific paper on color vision. This article is based on a study he made of his own disability.
Color blindness is usually hereditary but can also occur as a result of ocular trauma.
The woman with normal vision can be a carrier of the disease and transmit it to their children. The blindness of the red-green form primarily affects males.
A rare form of blindness, but especially common on an island in Micronesia, is the complete color blindness. The individual involved has a monochrome vision, that is to say, it only receives one color.
Some jobs require to distinguish colors, for example, the color of the wires in electronics. On the other hand, color blindness may be an advantage in certain situations. A certain type of colorblindness allows the military to better track a camouflage.
