Not a gp, but my eyes can’t stand some LEDs. I don’t know the exact physics of it, but sometimes even a reflected/diffused LED light feels like I’m looking into a laser beam. Colors are also very off, like in a ~chroma fog that isn’t there. Other people don’t notice anything strange. I’d appreciate if someone explained why, because I’m a regular trichromat with no obvious vision deviations otherwise.

Do you mean you have tested for usual https://en.wikipedia.org/wiki/Dichromacy and showed that you see all shades people usually see, or have you definitely tested for https://en.wikipedia.org/wiki/Tetrachromacy ?

You made me think about it twice, tbh. I have passed regular vision tests, but never tested for tetrachromacy specifically. I can distinguish 22-35 lines here, depending on how far I sit to ignore jpeg line separating artifacts and how much I unfocus my eyes. https://kfor.com/news/test-how-many-colors-you-see-can-deter... (so silly to choose jpeg for a color test, oh internet). I don’t think I am a tetrochromat.

I failed another one which asks have you seen this color “before”, but honestly I’ll fail it even on 20 different-hue color palette because I have no color memory and my color vocabulary is on a “3-bit male” side.

Also failed “choose 2 identical out of 4” type. They are all 3+1 unless I peer very hard.

Does it say something?

Ha. I have to admit while I don't technically have to wind it (at all) I still find myself doing that as well. Pick it up... wind it a prime number of times... put it on for the day.

Why a prime number?

Symmetry fixation thing. I sort of used to have to do most things an even number of times. Wind the watch. Pushups. Jumping jacks. Whatever. Anything that required a count. I switched to counting to a prime 3 or greater and the anxiety just went away. Been doing that for years now. Took me awhile to realize I was even doing it in my head... and luckily the fix was pretty easy.
