How Do You Get Two Different Colored Eyes?

Updated on April 29, 2015

A Beauty Mark in the Eye

Being born with two different colored eyes has always been a conversation starter for me. I do not have vision problems because of having two different colored eyes. I was born with one blue eye and an eye that is partially blue but mostly brown. My doctor tells me it is a birthmark and I have nothing to worry about. How does this multi-coloring happen?

According to Susan J.Gross, an associate professor at Albert Einstein College of Medicine, the chances of being born with two different colored eyes is somewhat rare. The color variation is due to genetics and a variation is the result of an increase or a decrease of pigmentation in the iris. An eye that is completely different in color from another eye is called Heterochromia iridium while an eye that has only partial discoloration as compared to the other eye is called Heterochromia iridis .

Most cases of different eye coloration at birth seem to be isolated and are sporadic. This trait is genetic. The chances of being born with two different colored eyes is some what rare. My eye doctor told me that it happens to one in one thousand people but further research online suggests that it is even more rare than that since the odds are not medically published.

Trauma can cause eye discoloration. This is what happened in the case of David Bowie. David Bowie also has two different colored eyes. He was not born with them. According to sources at Bowie Wonder, David Bowie does not have two different colored eyes. He has a condition called anascorsia. After a fight at the age of 14, David Bowie had two surgeries on his eye to repair torn sphincter muscles of his eye which left his pupil enlarged. This enlargement of the pupil is anascorsia. The enlarged pupil gives the appearance of two different eye colors.

If you notice sudden eye color changes or spots in your eyes that are a different color from your iris, consult a physician. Colors or spots in your eyes that were not previously there could be a sign of an underlying health condition and need the attention of an internist.

If You Are Not Born With It...

If you were not born with two different colored eyes and would like to avoid the permanent addition of multi-colored eyes via a bar fight, you could always purchase colored contact lenses. Colored contact lenses are inexpensive and fun. Besides being available in normal colors like brown, green and blue, colored contacts come in odd varieties, too. Red devil eyes or slant cat eyes or even black zombie eyes, to name a few.

Colored contact lenses seem to be a Goth fashion statement. Colored contact lenses for eyes are also a great addition to a Halloween costume and can really complete a look. Colored contact lenses are available online and through your eye doctor. If you do not need the colored contacts for a prescription lens then they can be purchased through a retailer without having to visit your eye doctor.

      I have a grandson who was born with one dark brown eye and one hazel/greenish eye. He will be six in June and neither eye has changed color. What is most likely to change color is his very blond hair, which usually darkens with age (although not always). My dad had hazel green eyes (both same color) and was very blond as a child. As an adult his hair was almost black!

      No way, mine were described just like the one in the description. I don't have red hair though.

      Hi Dolores,

      So funny, I am a red head, too! I wonder if our fair skin increases the chances of our eyes being two different colors? Mine never went away and that is a good thing because I love it!

      One of my sons had two different colored eyes as a baby until age 4 or so. Then they began to match. But the one brown eye and one blue eye, along with the red hair in ringlets sure got him a lot of attention! He was one amazing looking child. The difference even showed up in black and white pictures.
