What's wrong with my eye? (picture)?

What s wrong with my eye picture

It's a little hard to see, maybe, because my iPhone couldn't seem to get a good picture.
It's like 3/4 blue/gray, and 1/4 hazel-brownish looking?
What is it? And how rare is it?
I've only seen animals with it, no people. I know people have it but I've never met a person with different colors in their eyes at the same time.

It's most likely heterokromia iridium, which happens commonly in animals, but rarely in humans

I have a friend with this, and I wouldn't say there's anything 'wrong' with it. It's just an interesting colouration of your iris. I believe it's called Heterochromia, but while looking through wikipedia, yours looks more like "Sectoral Heterochromia" which pertains to the multiple colours in a single eye.
It can be caused by certain eye-drops, diseases, or injuries, says the wiki, but I couldn't tell you how you got yours. I wouldn't rule out the possibility of genetics, since I only have a very basic understanding of it since I only just skimmed the wiki article.
