two different colored eyes

Heterochromia refers to a difference in coloration of the iris of eyes. it is a harmless condition that results from differences in melanin. Heterochromia can either be partial or full. If someone has one brown eye and one blue eye, it is FULL Heterochromia. This condition may be genetic, and retained from birth, or it may be acquired, often by injury, in both humans and animals. Partial Heterochromia is fairly rare, and it results in certain parts of a single eye's iris being different colors from the rest of that iris. this may be represented by clouds of an offcolor hue in one eye, or by bands or sections of the iris in an eye being different colors, or different shades of the same color. Although people may have this condition, it is very common in certain types of animals. Cats and dogs, in particular, can be prone to heterochromia, and certain breeds may be more likely to have different colored eyes than others. Heterochromia is usually harmless, and simply the result of different levels of pigment in eyes. I think this information is valuable because now, when you see a person with two different colored eyes, you will be able to understand that it is just a harmless condition that doesn't affect the persons body, just their appearance.
