Color blindness, also known as color vision deficiency, is an eye disorder that leads to the inaccurate ability to identify or perceive differences between some colors that people with normal sense of sight can easily differentiate. This condition is typically genetic or inherited but may also be brought about by damaged optic nerves, dysfunction in the brain, or as a negative result of exposure to certain chemicals.
While generally inconvenient, color blindness is only deemed a minor or mild handicap. Some studies even found an advantage in colorblind vision, concluding that individuals with color blindness perform better in penetrating certain camouflages.
Color vision deficiency may be acquired or inherited (genetic or congenital). Inherited color blindness is classified into three: monochromacy or total color blindness, dichromacy, and anomalous trichromacy. Inherited color blindness is more prevalent in males than in females due to the fact that many of the genes responsible for color vision reside in the chromosome.
