Can eye color color change and what causes it?

Answer 1

Eye color can change, although it is very rare.

Eye color is a multi-allele trait (meaning that it is controlled by factors linked to several different genes). This is what causes the many different eye colors. Darker colors are dominant and lighter colors are recessive. This means that darker colors occur more often than light colors. Eye color is produced in the eye and from day to day, depending on health, diet, and other factors, this production may be slightly increased or decreased.

Also as a person ages, many of the production sites for the pigment can decrease.
