Is my fish partially blind? One eye is entirely black, while the other looks normal.?

I've had three goldfish for about some time. But one of them, the calico fantail, has a completely black eye, while the other one looks completely normal, just like the other two fish in the tank. Thing is, it didn't just TURN like this after it stayed in my tank-- when I bought it, it's eye was black. It couldn't have been my accidental doing, then. Does this mean that it's blind on that side? It seems to swim a little awkward at times, and I'm thinking that's the case. I don't know. Why do fish get black eyes, anyway? Is it just the way they were born?
 
Its common in calico goldfish. I don't believe it affects their sight at all, but the calico genes themselves might, especially if its matte (kinda see through filmy grey calicos whose color appears to be below the surface of the fish's scales) which is a result of breeding two regular calicos together.
