Most people only have one eye color, but sometimes you can find someone with two different colored eyes.
So what’s up with that? Is it a genetic fluke or something more?
It turns out that having two different eye colors is pretty rare. It’s so rare that it only happens in about 1% of the world’s population.
How rare is it to have two different colored eyes?
It’s relatively rare, but it’s more common than people think. Approximately 1% of the population has some form of Heterochromia. That can be in the form of two different colors in the same eye or a difference in color between the two eyes.
What is Heterochromia?
Heterochromia is a condition where the colors of your eyes are different. It can be partial, where only part of the iris is a different color, or complete, where the whole iris is other.
It can also be acquired, which means it’s something that develops later in life, or inherited, which means it’s passed down from your parents.
Heterochromia is relatively rare, and there’s no one definitive cause. Some people are born with it, while others develop it later in life due to injury, disease, or certain medications.
Heterochromia can be found in all types of animals, not just humans. So if you ever see a cat with one blue eye and one green eye or a dog with one brown eye and one blue eye, they’re probably heterochromatic!
Causes of Heterochromia
There are a few different causes of Heterochromia, but most cases are due to genetics. It’s a trait that is passed down from parent to child.
Other causes can include diseases or injuries that affect the pigmentation of the eye or certain medications that can cause changes in eye color.
Heterochromia is usually harmless and doesn’t affect vision, but it can be a sign of a more serious underlying condition in some rare cases. Therefore, if you have Heterochromia and are experiencing any other symptoms, you must see an eye doctor for a complete evaluation.
- Complete Heterochromia: One iris is a different color than the other. This type is pretty rare.
- Sectoral Heterochromia: A sector of one iris is a different color than the rest. That is the most common type.
- Central Heterochromia: The center of the iris is a different color than the outer ring.
- Mosaic Heterochromia: This type occurs when two or more colors are in the same iris.
Heterochromia can be hereditary, meaning it’s passed down from your parents, or it can occur spontaneously. If you have Heterochromia, it’s likely that someone in your family also has it.
While Heterochromia is considered a rare condition, it’s more common than you might think. Approximately 1% of the world’s population has some form of Heterochromia.
So, if you have this condition, you’re not alone!
Famous people with heterochromia iridium
Heterochromia iridium, more commonly known as two-toned eyes, is a rare condition that causes the irises to be of different colors.
While the condition is usually benign, it can sometimes signify a more serious underlying health condition.
Despite its rarity, many famous people have heterochromia iridium, including:
- Mila Kunis
- Gracie Allen
- Jane Seymour
- Kate Bosworth
- Dan Aykroyd
- Elizabeth Berkley
- Henry Cavill
- Benedict Cumberbatch

- Josh Henderson

How to treat heterochromia iridum
There is no need to treat Heterochromia, as it does not cause symptoms.
However, treatment may be necessary due to an underlying condition.
In most cases, Heterochromia is simply a matter of cosmetic concern. However, if you are unhappy with how it looks, there are several options for changing the appearance of your eyes.
You can wear contact lenses that cover your irises completely, or you can undergo surgery (Iris depigmentation) to change the color of your eyes.
Iris depigmentation is a laser procedure to burn the iris pigment. The destroyed coloring is eliminated if everything goes well.
This treatment is allowed in some countries, but the US FDA does not yet approve it.
Whatever you decide, heterochromia iridium is not a reason to worry about your health.
