Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye 's iris [ 1][ 2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [ 3]: 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in ...
Infant visual development. A seven-week-old human baby following a kinetic object. Infant vision concerns the development of visual ability in human infants from birth through the first years of life. The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object ...

Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
What Causes Hazel Eyes? Eye color is determined by the amount and distribution of melanin in the iris of the eye, in addition to the genes we inherit from our parents. With most eye colors, the ...
Heterochromia iridum. Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [ 1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment ). It may be inherited, or caused by genetic mosaicism ...
Grey eyes make up about 3 percent of the world's population—the second rarest eye color. There are also rare cases of violet and red-colored eyes. What Determines Eye Color?
The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; [ 8 ] in some non-human species this polymorphic variation is even greater, and it may well be ...
