Answer 1

That doesn’t describe what I see: I can shift which eye is currently dominant, even when one eye is closed. And when my open eye is dominant, sure, I see “nothing” out of the other, but if my closed eye is dominant, I see… black*, with the image from my open eye “behind” it, just as expected.

* Well, not usually 100% black, especially if I’m paying attention to things like “which eye is dominant,” but kind of a dark grey with visual snow
