> I'm not a brainologist, so I'm not sure why the 3D system on the 3DS works for me when nothing else does. I'm still nearly blind in one eye, and the 3DS relies upon a lenticular stereoscopic effect that requires two eyes. Maybe the newer VR headsets would work for me as well; I don't know.
Not a brainologist either, just a guy with a maths/physics degree who works in IT. My first thought is that the 3DS was close enough to your face that the parallax might have been apparent just from your one good eye looking at different places on the screen.

- JohnBooty 6y agoFor folks missing an eye, "manual" parallax is one of the primary ways we do depth perception in real life - you get it for free by having two eyes; we have to move our heads around sometimes. =) That's an interesting theory but I think that's not what's happening. For those unfamiliar, the 3DS uses a lenticular screen. It renders two separate images: the "right" and "left" image. The one you see depends on your viewing angle. If my good eye was seeing both images, I believe I'd experience a sort of double vision or as least discontinuities. Perhaps more to the point, the 3D effect disappears if I close my "bad" eye! So my "bad" eye is contributing... somehow.
