1) Would it be possible in real life for a person with effectively no vision to fool other people into believing they're sighted? (We'll go ahead and optimistically assume that this hypothetical person has advantages like foreknowledge of the layout of their environment, a sighted co-conspirator, etc.)
2) Even with no vision besides light perception, would it be possible for them to learn to fake eye contact in face-to-face conversation?
3) If either of these were hypothetically possible, how long might it take to get good at doing them? What kind of things would the person have to keep in mind/especially be careful about? Would any specific items/tools be particularly helpful? (There is magic in this fantasy world, but it's unfortunately not any kind applicable to this issue.) What kind of practice would be useful? Again assuming that they will have at least one sighted person to help them with said practice.
I tried googling various combinations of the terms "blind, person, faking, feigning, pretending, sight, sighted, vision, sightedness" and unfortunately, mostly came up with stuff about sighted people pretending to be blind. :/ Also checked the tags here and poked through the Nanowrimo forums.
Cookies to anyone who guesses the fandom...
Edit: I should probably also mention he lost his sight in the first place via
