Heterochromia is the term used to describe a difference in a person's eye color. Someone with central heterochromia has different colors within the same eye. Complete heterochromia is when they have two different colored eyes.
Heterochromia of the eye is caused by variations in the concentration and distribution of melanin, the pigment that gives color to the skin, hair, and eyes.
The word "heterochromia" is derived from ancient Greek where "heteros" means different and "chroma" means color. The condition is also known as heterochromia iridis or heterochromia iridum.
