The iris plays no role in the effect, but the blue-eyed people have relatively low melanin in the fundus as well. Therefore, they show a much stronger red-eye effect, as the light passing fundus is not absorbed by melanin. The role of melanin in red-eye effect is nicely demonstrated in case of heterochromia (one eye blue, one brown): typically, only the blue eye displays the effect.Created by: Kantapat Rassameehard 57% blue-eyed peopleblue-eyed people3084brown-eyed peoplebrown-eyed people790elderselders82there is no differencethere is no difference1416eyes riddles » Why do cats have vertical pupils?To better see in the dark.
