![]() ![]() Eye color can change over time, especially during infancy and early childhood. In some cases, certain eye conditions or diseases can cause a temporary purple appearance, but this is not a natural eye color. Eye color distributions vary by geographic region. Whether you have the most beautiful eyes in the world or an average pair of peepers, eyes are the one part of the body that has to remain exposed (to some extent) in every culture around the world.Even the most conservative cultures have to allow people to show their eyes in order to let the light in. Although people with green eyes are relatively rare, accounting for less than 2 percent of the world’s population, that still adds up to approximately 150 million people across the globe. When this happens, the iris's color may look less intense, because the pigment is more spread out, he said. The perception of purple eyes may be influenced by lighting conditions, eye makeup, or photo editing techniques. Also, 8 percent of the world’s population has hazel eyes, and another 8 percent has blue eyes. About 80 percent of the global population lives in countries that are net-importers of fossil fuels - thats about 6 billion people. In contrast, when the eye is constricted, on a bright sunny day, for instance, the pupil shrinks and the iris grows in size. ![]() 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. Widely known for having the most striking eyes in Hollywood, Taylor had what appeared to be rare natural purple 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. 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.
