What is it called when someone has two different colored eyes?

Heterochromia of the eye is called heterochromia iridum or heterochromia iridis. It can be complete or sectoral. In complete heterochromia, one iris is a different color from the other. In sectoral heterochromia, part of one iris is a different color from its remainder.

Is Heterochromia dangerous?

Central heterochromia may be a rare condition, but it’s typically benign. In most cases, it doesn’t affect vision or cause any health complications. However, when central heterochromia occurs later in life, it may be a sign of an underlying condition.

Why are green eyes so rare?

Green eyes have low to moderate amounts of melanin and they’re super rare—only an estimated 2 percent of the population have them. And according to research, they’ve been around since the bronze age.

Can 2 brown eyes make a blue eyed baby?

Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. However, since eye color is polygenic, several other genes exert their effects as well. So yes, while it’s unusual, it is very possible for blue-eyed parents to have a brown-eyed child!

Do purple eyes exist?

Can Heterochromia cause blindness?

Heterochromia iridum, which is the technical term for having two differently colored irises, is unusual, but it is not rare. In Kunis’ case, her heterochromia was a symptom of chronic inflammation of the iris that caused blindness in one eye. Fortunately for the starlet, surgery restored vision in the affected eye.
