what is the scientific answer to: why do people have different eye colors?
- 1 decade agoFavorite Answer
Our eye colour is basically determined by the combination of colour
pigments on our iris (i.e. the ring of muscle that control the diameter of
our pupil, which is controlled by reflex involving the mid-brain). In
essence, there is a pigment called melanin that gives rise to colour in
the hair, the skin and the iris and the choroids layer of the eyes.
Melanin is contained within special cells called melanophores, and is
produced by the metabolism of the amino acid tyrosine. There are a number
of different type of melanins, and different combination of the different
melanins give rise to the difference in our eye colours.
