![]() Pigmentation in the eye is essential for normal vision. This condition reduces the coloring (pigmentation) of the iris, which is the colored part of the eye, and the retina, which is the light-sensitive tissue at the back of the eye. When this happens, the iris's color may look less intense, because the pigment is more spread out, he said. Ocular albinism is a genetic condition that primarily affects the eyes. But the blood vessels inside can show through the colored part (the iris), and the eyes can look pink or red. Most people with ocular albinism have blue eyes. ![]() In contrast, when the eye is constricted, on a bright sunny day, for instance, the pupil shrinks and the iris grows in size. Why do albinos have red eyes Albinism keeps the body from making enough of a chemical called melanin, which gives eyes, skin, and hair their color. Some types present with reduced melanin rather than lack of melanin. In fact their irises vary in colour from light gray or violet, to the most. When an eye is dilated (that is, when the pupil is large so that it can take in more light), the iris is compressed and may look darker because the pigment is crammed into a smaller area. There are different clinical types of albinism, including Ocular Albinism (OA). It is a very common misunderstanding that people with albinism have pink or red eyes. But he mused that it might be possible if a person had light blue eyes and prominent red blood vessels, as blue and red make purple.įurthermore, he added that eye color might appear to change when a person's eyes dilate or constrict. When asked about the rumor that actress Elizabeth Taylor (1932-2011) had violet eyes, Fromer said that he's never heard of, or seen, purple eyes. Instead, the red color comes from the blood vessels that support the iris, Fromer said. Purple irises can result from a genetic mutation that may or may not be related to a condition called albinism. ![]() In reality, their irises don't have any pigment, because the gene that controls the production of melanin is completely turned off in albinism. It's a common misconception that individuals who are albino have red eyes. With a few exceptions, such as the red-eyed tree frog, red is usually not included on this color scale.
