If someone is blind in one eye, is it possible that the eye would look completely normal, and exactly like the other eye? Is there a cause of blindness that would not affect the appearance of the eye? (Or at least, affect it only very slightly)
Would it be possible for the fake/blind eye to move in coordination with the other eye?
How would the blindness in one eye affect the vision in the other eye?
Would the person be able to, say, shoot a gun with accuracy? Would he be able to drive?
