That's weird, dude. You either have a disease, or someone else in your family passed you the genes... or you have contacts.
Pretty cool looking eyes, but they definitely don't deserve their own thread. Maybe if they looked like this...
Well, either someone in your family passed you the gene or it's some outside factor. You might have had a viral infection that changed the colors of one of your eyes while in you were little. Are you male or female, because if you're female, the cause could be X-inactivation. By the way, your condition is called "Heterochromia". From what I'm seeing in research, hererochromia is more common in females than it is in males, but just slightly. I like your eye color, though. Is it always like that, or just on some days?
