So I have a character who's blind in one eye. The problem is, the character he's based on is actually *missing* an eye, which I don't want to duplicate, but do at least want to acknowledge. Now, I know it's entirely possible to be blinded in one or both eyes without actually losing them, or even being noticeably scarred -- I knew a guy for a year before finding out he was blind in his left eye, for example. But is it possible for someone to be blinded without injury to the eyeball itself, but with mild facial scarring?
What I mean is: would it be possible for my character to appear to have two functioning eyes, but to still have a small scar on his face, something like this?
