Albinism is a condition wherein the human body does not produce enough of the pigment melanin. In some cases, there may be absolutely no melanin produced. The lack of melanin results in a discoloration of the skin, hair and iris of the eye. Persons suffering from albinism have extremely light hair, pale skin and no color in the iris. This allows the blood vessels at the back of the eye to be seen and make them appear red-eyed.
