Heterochromia - deformity or beauty? (12 photos)

Heterochromia is when a person has different eye colors. The difference in eye color in a person is caused by an excess or lack of pigment - melanin. Such a rare phenomenon occurs not only in humans, but also in animals, for example, cats. A long time ago, people with different eye colors were considered children of the devil, witches, that is, people associated with witchcraft or black magic. They caused fear among ordinary people, but now it is known that different eye colors are not the tricks of a supernatural force.




There are two types of heterochromia: the first is complete heterochromia, and the second type is partial heterochromia. In complete heterochromia, the color of one iris is completely different from the color of the other iris. In partial heterochromia in a person, one part of the iris (eye) is different from the rest of the iris, meaning one eye has two colors. Most often, complete heterochromia occurs in humans, less often partial, in about 4 people out of 1 million.



Heterochromia is a mutation that occurs after the fertilization of an egg. But you should not be afraid of heterochromia. It does not affect the health of a person who has different eye colors. A person with heterochromia sees and perceives colors in the same way as an ordinary person, but only he has his own individual zest. By the way, heterochromia is more common in women than among the stronger sex. It also happens that heterochromia becomes acquired. Due to an injury or disease (Hirschsprung's disease, Waardenburg syndrome), a person acquires a unique phenomenon.
