Tree filled valley
Bildnummer 12003107
| Scene of a tree filled valley used to demonstrate normal color vision. This image is used in contrast to a similar image used to demonstrate color blindness. Color blindness is the lack of perceptual sensitivity to certain colors. There are three types of color receptors in our eyes,red,green and blue. Color blindness is a result of a lack of one or more of the types of color receptors. Most color perception defects are for red or green or both. About 10% of males have a color perception defect,but it is rare in females. Red-green color blindness is a result of a lack of red receptors. Another form of color blindness - yellow-blue is the second most common form,but it's extremely rare. It is also possible to have the color receptors missing entirely,which would result in black and white vision | |
