which just goes to show, like I said, your vision is not a camera. perfect accuracy is not one of its goals. it does not give any shits about "objective reality", that's not important.

Anyway, back on how amazing and crazy your vision is: There was an experiment back in 1890 where someone wore glasses made with mirrors in them to flip their vision. After about 8 days, they could see just fine with them on. Their vision system had started "flipping" the image.

(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

Nah. it's not a laser, and it's not intense enough. regular incoherent IR lights are everywhere (on your remote control, on most security cameras), they don't cause any harm.

Question - can watching a TV monitor which is displaying an active laser working damage your eyes in any way? I always question the need for laser goggles during endoscopic laser treatments
-
looking at a monitor should be fine, it can't produce any damaging light. Maybe the goggles are just in case the laser accidentally is mis-aimed prior to insertion?
