2024年10月9日 · Learn about what having purple eyes mean and the rare genetic condition that can cause this unusual eye color.

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.

While rare, purple or violet eyes can naturally occur, due to a mutation, inflammation inside the eye, or a condition called albinism. What determines my eye color? The pattern of eye color inheritance is complicated.
