In my last eye exam, I ran into something like this - the guy said
something like "Is the red dot inside the box" (or whatever, I don't
recall exactly). I replied "It can be - do you want me to do that?"
He responded "What?", so I explained that I could freeview and cross
eye and that basically I had no particular pre-conceived notion of
where an image ought to be (based on convergence/divergence...).

Now what's *really* amazing to me are the people who seem to totally
decouple the eye muscles and let one wander around while "viewing"
with the other. I can't imagine how you do that (at least once the
circuitry is "hard wired" into stereo vision after you are a baby...)
