Common terms are abnormal color vision, color deficiency and color vision confusion. Females maybe be effected by color blindness, but usually they are just carriers. Males are more often affected. About 8% of males and 0.5% of females are effected by color blindness. Although color blindness may be a result of another eye disorder, the majority of color blind cases are hereditary and present at birth. The retina, is a complex nerve system which converts light energy into electrical energy that is then transmitted to the brain. This conversion is accomplished by two types of receptor cells in the retina called rods and cones do to their shape. The cones are responsible for converting the color. Each cone contains visual pigments that are sensitive to one of three wavelengths of light: red, green and blue. Normally, all colors of the spectrum are able to be matched by mixtures of only three colo
The Physiological Factors That Effect Color Perception, unknown website. Tritanopia are those who have trouble distinguishing blue and yellow. This disorder is much less common than the red-green colorblindness, and is usually acquired, not received through heredity. These people may see both blue and yellow as white. They may even see mint green or pink as an equal to light blue. Red color blindness is the most common. This is when the red color receptors are nonexistent.
