what's important to the evolution of the visual system is any trick that helps you survive, no matter how "dumb" or "weird" it is. So if you want an accurate visual representation of what things look like? Use a camera. Not your eyes.

(I say flipping in quotes because it's not as simple as it started showing the pixels at the top row on the bottom row, cause our vision doesn't work like that) It only took them a few hours to get back to normal after taking these glasses off, though.

The last really fun part about this flipping experiment: your eyes already do it. Based on how our vision is wired, we should be seeing everything upside down. We don't, but only because our visual system has had our whole life to adapt to this.

BTW, since a few people have brought it up: There's a great sci-fi novel by Peter Watts called Blindsight. In it humans encounter an alien race they call Scramblers, who can move very fast and precisely, and they exploit saccades.

because if they only move during saccades, we never see them moving. and since so much of our vision is based on just filling in what we think is there, if they stay out of the direct center of our vision, we'll just visually fill them in, like they were never there.

Check it out if you're into hard SF stories of first contact. It's got some really neat ideas about human vision, very unique aliens, the nature of conciousness, the future of humanity in the face of perfect VR, and vampires. (Really, it has "vampires", while still being hard-SF)

BTW, remember how I said "vertebrate eyes" up there? Guess who has eyes which are wired forwards instead of backwards (no have no blindspot), have an internal lens, and can even see polarization of light? our good friends the Cephalopods!pic.twitter.com/SOMT5CB2SY

After playing BeatMania or Dance Dance Revolution or any game where you concentrate hard (for a sustained period) on patterns perpetually falling down the screen, everything appears to drift the opposite way (upwards) for a while. Perhaps related to vision system hacks?
-
Yeah, I think so. Your vision system is always trying to compensate for movement to try to get a clearer image, so it can be tricked by these kind of "after-images".

Well...there's a considerable literature about attempts to repeat Stratton's 1897 experiment. It works better in theory than practice.

ooh, that's good to know. Thanks!
