      This is because of different amounts of pigment in the iris of the eye. This may be an adaptation in people in the past to different climates and levels of sunlight

      Eye colour is due to different amounts of pigment which produce the colour. Eye colour can regulate the amount of light that goes into the eye, acting as a filter. So darker eyes absorb more light and so would probably mean that if you had darker eyes you would cope better with high amount of sunlight…
