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.

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.

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!

if you can't get it done in time, turn back the clock and pretend you did. That's a perfectly good solution when you're the visual system.

BTW
@hierarchon reminded me of a neat trick with saccadic masking: go look in a hand mirror. no matter how close you bring it to your eyes, and how much you look around, you will never see your eyes move. You're blind during those moments. But you still think you are seeing.596 proslijeđenih tweetova 5.046 korisnika označava da im se sviđaPrikaži ovu nit -
she additionally pointed out that your phone's selfie-mode is NOT a mirror, and it has a slight delay, so you can see your eyes moving in it.

And for fun, here's wikipedia's example of the blindspot. Stare at L with only your left eye, adjust the distance, and the R will disappear. You don't see "nothing" or "black", you see the background, because you expect to.pic.twitter.com/NBN485EOvC

This is why laser damage your retina can be so insidious. Your visual system already can hide "holes" in your vision, what's one more to hide? So you damage a small spot of your retina and your visual system covers it up.

but since you didn't go "WELL THAT WAS TERRIBLE I BETTER TAKE BETTER CARE OF MY EYES" and stop fucking with lasers, you keep doing it eventually you accumulate so much damage that your visual system simply cannot manage hiding it all and your vision rapidly degrades.

the other reason lasers are so dangerous is that they don't necessarily trigger the same responses as regular incoherent light. your pupil reflex is only triggered by some special cells in the center of your eye, so an off-center laser might not cause your iris to contract
