Color Blindness

Individuals who are color blinded, may be blinded may be blind to one, two, or all of the colors red, green, and blue. (Blindness to red is called [|protanopia] ; to green, [|deuteranopia] ; and to blue, [|tritanopia] .) (1)



The most common cause of color blindness is blind to see red, green or blue. For red defectiveness is called protanopia.Protanopia is a red-green color blindness. Protanopia is the first type of red-green color blindness. One of the three cones in the eye is affected. The L-cone may be affected or the cone is completely missing and the empty space is affected. When the L-cone is missing then it is called protanopia or “red dichromacy”. People who are dichromats have only two working cones, whether the S-cone and M-cone, or L-cone and M-cone etc…

Hereditary red-green color blindness, which affects about 20 times as many

as females, is a sex-linked recessive characteristic. The mutation is the gene. A woman must inherit the trait from both parents to be red-green color-blind. A red-green color-blind man and a woman of normal [|color vision] have daughters who have normal [|color vision] but are carriers of the trait—that is, the daughters may have red-green color-blind sons and daughters who are carriers. The sons of a red-green color-blind man and a woman with normal vision who themselves have normal vision are unable to pass the red-green color-blind trait on to offspring. The son of a normal man and a carrier woman may be red-green color-blind, and the daughter of such a union may be a carrier. Thus, red-green color blindness tends to skip generations. (1)

Color blindnes may occur because of it is inherited from mother’s genes. Color blindness affects mostly boys. Color blindness may be the result of eye diseases or vision problems. Color blindness may be frustrating depending to how many colors you are blind to. Frustrating because you make mistakes with the color of clothe so it becomes humiliating.



There are benefits in military terms. For example camouflage won’t work on color blinded individuals. Britannica [] Colour Blindness []
