how do eyes work!!!

i had a Moment last night where i discovered that. ok you know the youtube logo? bright red rectangle with the white triangle?

pretend this text is a triangle

right so when that's displaying in the corner of our TV (idk what kind of display it is sorry!!!) and i'm wearing my glasses, if i move my head around while looking at it (i.e. change the angle and area of the lenses i am seeing it through), the red rectangle appears to MOVE, with respect to the white triangle and white text next to it??????!!!??? like the triangle literally goes off-center and the "YouTube" text becomes misaligned! what the fuck!!!!!!

now i'm also remembering: when i first got my work computer, a macbook pro, something that was really throwing me off was the red "close window" button looking misaligned with the other two stoplight buttons!!! like i even remember taking a piece of paper to the screen and using my screenshot tool to verify they actually line up!

oh and another thing!!! there are certain colors — and by "certain", yes, i mean red (but it has to be on a dark background) that have always appeared to "pop out" of my phone screen (it's an AMOLED, i just checked), like not just ~pop~ in a "wow what a bright color" way, but actually as though it is on a different three-dimensional layer than the other colors. and it occurs to me now that this is? because of this whole "movement" thing??? creating an illusion of depth???????

HEY i just remembered another thing to add to the stream of consciousness: i have "blue blocking" lenses, that has got to be related to this phenomenon?? i'm also noticing some... blue and red distortion on the top/bottom edges of the rectangle example above when i "move" the rectangle???? wow this is cool thanks for coming with me on this journey

It’s your glasses, yep. Strictly for analogy’s sake, your eyes are okay for seeing, but lousy at focusing, so you wear a fancy screen on your face that serves the same purpose for your eyes as subtitles do for your brain.

When you move your head so that the same light hits the glasses at a different angle, you’re doing the inverse of when you walk around whilst watching TV. The same way an image on TV might look clear from up front and fuzzy from over here, a clear image in your glasses might look up front head-on or over here in your peripheral vision.

End weird analogy.

that last thing is called "chromatic aberration" and we hate it to the point that we got contacts, because our glasses prescription guarantees chromatic aberration

damn so this would happen even with clear lenses?? my prescription hasn't changed in a long time but maybe i didn't notice it for a while is because i spent most of the last decade up to this year wearing contacts. wild

alex tax1a @atax1a12/31/2022, 6:57 PM

yeah, it happens because of the index of refraction of the lens causing the light to basically prism out. it is much less noticeable with contacts because there's less physical optic to lens though.
