Genetics of Eye Color Change

Abstract

One would expect that a trait like eye color should remain constant throughout the person's lifetime, but many people experience eye color changes: slight or very obvious. Various factors can cause change of eye color in humans. The majority of children have some eye color change after the birth. Typically, newborns have blue eyes, which change to green, light blue, light brown and dark brown, as they grow older. It is thought that exposure to light after birth triggers the production of melanin in the iris of the eye. By three years of age, the eyes produce and store enough melanin to have their natural shade.
