<P> There are different types of oculocutaneous albinism depending on which gene has undergone mutation . With some there is no pigment at all . The other end of the spectrum of albinism is "a form of albinism called rufous oculocutaneous albinism, which usually affects dark - skinned people". </P> <P> According to the National Organization for Albinism and Hypopigmentation, "With ocular albinism, the color of the iris of the eye may vary from blue to green or even brown, and sometimes darkens with age . However, when an eye doctor examines the eye by shining a light from the side of the eye, the light shines back through the iris since very little pigment is present ." </P> <P> Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure . </P> <P> The human eye normally produces enough pigment to color the iris blue, green or brown and lend opacity to the eye . In photographs, those with albinism are more likely to demonstrate "red eye", due to the red of retina being visible through the iris . Lack of pigment in the eyes also results in problems with vision, both related and unrelated to photosensitivity . </P>
