What is heterochromia?


The amount of melanin in the eye is what gives color to our eyes. Most melanin is found in brown eyes and at least melanin is found in blue eyes. It can be said that in heterochromia the concentration of melanin in the distribution or the different condensation of the scarcity results. Heterochromia does not prevent you from seeing it because it is not a disease because of the fact that it is not a disease and it does not constitute a situation that threatens our health of course unless it shows serious increases. Heterochromism is not only found in humans but also in animals.

The most familiar example of heterochromia is the people having a blue eye and a green eye. Scientists found out that heterochromia is usually inherited and congenital; however in some cases it may also show itself as a subsequent change in color during childhood. Heterochromia can occur for many reasons. There are three different variations of heterochromia.

Well what are variations of heterochromia?  Full Heterochromia, Piece Heterochromia and Central Heterochromia are the three variations of heterochromia.

In the case of Full Heterochromia the two eyes are in completely different colors. It may appear that one eye is brown while the other eye is blue or green. Alice Eve‘s eyes are examples of full heterochromia.

In the case of Piece Heterochromia, only part of the iris is of different color. You can think of it as a spot of different color in the eye. Jonathan Rhys Meyers is fame with fragmented heterochromia.

In the case of Central Heterochromia, the central part of the iris is in a different color than the true color on the outside of the eye. It can usually be observed as blue-greenish yellow in the middle. People with such eyes are usually called cat eyes.
