Heterochromia means different (hetero-) colors (-chromia).. Usually the term is used to describe the condition where a person has different colored eyes â one blue eye and one green eye, for example. Other terms to describe different colored eyes are heterochromia iridis and heterochromia iridum. Iridis and iridum refer to the iris of the eye. The iris is the thin, circular structure that surrounds the pupil and contains the pigment melanin, which gives our eyes their distinctive color.
Eye color is determined by the differences in amounts and types of pigments present in the iris. Pigments are determined often by genetic alleles, however some conditions can â¦ cause a change in eye color. I would have stopped here however you asked WHY do eyes have color, and not HOW do eyes have color. Hence you may suggest that eye color has some functionality, and you wish to query this.
