Well, I'm no expert on genetic deformities, but that sounds right to me, and the socket looks clean and has no scars, so I'd bet she's shed successfully at least once.
One-eyed snakes are fine for pets, best not to pass genetic problems on by breeding from them of course. Only problem I ever had with my cyclops was that he was a bit jumpy if approached on his blind slide, so I'd always make sure I put my hand, or food, where he could see it.
So, I'd say go for it - give a disadvantaged animal a good home!
