I've heard of this test before, and it makes no sense to me. If I focus on a distant object, I see two images of my hand, one for each eye. So I'd have to choose which one to put over the object.
What? I think most people see them together. Do you have to consciously compare the two images to perceive depth?
Not at all, I perceive depth fine.
If I focus back on my hand, the two images align, and I see both images of the background. It's just that I'm always seeing information from both eyes.
If anything, from my perspective it's everyone else who I would expect to have difficulties with depth perception. You're only perceiving one eye consciously, (In the binocular overlap region), and the other eye is just used for depth information by your subconscious, is that correct?
No the brain does funky stuff mixing the pictures together. If I move something close enough to my face it appears in view twice seemingly semi-transparent. The rest of my visual perception remains unaffected though.
Are you also constantly aware of your blind spot(s)? (Something that with the single image is completely invisible)
That sounds like what I experience, not just for things very close to my face, whenever my eyes are aligned to something in front or behind.
But in order to do the dominant eye test, you need to only see one image in the foreground and background simultaneously. So how does that happen unless the view from one eye is at least partially supressed?
This is one of those things that's really hard to talk about and describe, but I would love to actually understand it. Also no, I can't notice my blind spots.
