Maybe this has happened to you: one day you're sitting at home watching TV and suddenly you notice that your favorite actor or actress has 2 different colored eyes. Is it a special effect, or colored contacts?
It's actually a very common condition called heterochromia, and you probably know someone that has it (even if it's very subtle). Some people are just born with two different colored eyes.
The contract can be drastic: Kate Bosworth, who starred in Superman Returns, has one light blue eye and one blue-brown eye. The actress normally wears a contact lens when she's playing a character, because it can be very distracting.
Likewise, Dallas star Josh Henderson has a very light blue eye and a deep green one. But in his case, the condition is more severe. While most cases of heterochromia are harmless, it can also be caused by eye injuries early in life. Henderson's condition left him nearly blind in his left eye.
Mila Kunis was also blind in one eye, until she had corrective surgery. She can see perfectly fine now, but her heterochromia is still there (her right eye is lighter than her left).
It turns out lots of stars have very mild cases of heterochromia, which gives their eyes a distinctive "multi-color" look. From Dan Akyroyd and Robert Downey Jr. to Christopher Walken and Joe Pesci, these actors can all credit their "striking" looks to the condition. See if you notice it the next time you watch one of their movies!
