in any case the original point was that while you might know this about your eyes being poor cameras that lie to you, you might still think that at least they're consistent, time-wise. they don't screw with your sense of time passing, just to make up for visual defects. NOPE!

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

Great thread! We had some prism glasses in the psychology dept where I studied. I remember those being left/right rather than up/down, but my memory may be failing. A very striking effect, and disorientation on removal / eventual tolerance of both states was fascinating :)

That's really interesting : the way our brain can adapt but still go back to a normal behaviour.
