I have the theory (probably there are already studies of that) that our vision isn't exactly perfect and according to what we perceive, but instead it's actually kinda noisy, there's always stimulus that can produce that noise in the retina (plus the interferences and cost of having to transfer all that information from the eyes to the visual cortex, which are basically in opposite sides of the head) And our brains make the job to "de-noise" it, but when we stare to a truly flat color like a clear sky or closing our eyes, we will be able to "see" (being conscious of) that "noise"
That part about colors seeming to invert actually reminds me of a book I was shown in my art class back in elementary school, “Hello Red Fox!”, in which animals appear as the opposite color of what they’re described but supposedly if you look hard enough you’ll see them change It never worked for me but it did for the characters
2:32 - 2:46 I remember seeing a similar prompt in books featuring optical illusions that I loved reading as a kid. My questions have finally been answered
That's why my sight got brown when my eyes finished the super powerful light test for my floaters. Seriously its cool yet its scary! Thank you for the video for its explanation!
The whole thing of Phosphenes have always fascinated me, even since I was a kid, as I’ve always suffered from Migraines, and whilst I do get them if I touch my eyelids (rubbing, tightly closing the lids etc.) they also appear for some people who have migraines, (auras or spots) which makes me think it’s both the eyes but also some sort of pressure in the muscle layers in the brain or something that also affects it, really interesting stuff
When i was younger I used to press my eyes and watch the kaleidoscope display, I was fascinated by the images and colours and I didn't care how much it hurt me... pain for knowledge
Once upon a time after spending a couple hours in a red lit dark room only to come outside and notice everything looks blue. Really freaked me out when it happened.
On long road trips when I was a kid, I would cover my eyes till my night vision would kick in, I would open my eyes for a second and view the image till it faded.
I get this when I close my eyes in a hot shower or when I squeeze my eyes closed in the dark. I figured it was something similar to putting pressure on an LCD screen. Our brains are doing something similar to what makes the screen work. If you apply heat or pressure to LCD screens the layers of backlighting and liquid crystals become misaligned or damaged and you see weird spots and colour changes in the display.
As kids, during sleepovers me and my friends would be lying in our sleeping bags, camped out on the downstairs floor or backyard, and we’d do the thing where you gently push on your eyes to see that vivid light show. Hey, it was the 80s - we were easily amused back then lol
I had wondered why i can have color floaters. i don't see anyone talking about it. but at late 2023, i finally knew: photoreceptor contracted temporary. this caused some kind of color alteration. that's why it's color is swapped: certain color cones had reduced sensitivity for a while. although i may not recall correctly or it's just a theory, i might be closer than i thought. i understand why you're wondering and took so long to finally get answers, because we don't see anyone else wondering the same thing, so we forget to google or just move on and do anything else. very interesting
I always thought it was because some receptors would for a brief moment get hooked into another (like a few ms) as they are very close together and when you excite them too much or make a too fast of a motion they for a brief moment get glued together causing a freeze frame or wrong signals to the brain.
I have seen sometimes a strange effect that looks like if someone had thrown perfectly triangular mirror confetti inside my eyes. It looks kind of "beautiful" because they look like if you had one of those snowballs full of perfectly cut little triangles that are thin in one of the corners, they all have the exact same perfect shape, and they look like if they were golden or silver glitter in behavior and shine, and the way that they rotate in all directions. It only lasts a few seconds, but it is a very showy effect. It's quite rare to happen, I'm not sure if it does when I have low pressure and I suddenly stand too quick or something. The cause doesn't seem to be always the same.
You fergot the coolest phosphenes that, when you carefully focus your eyes, pulse behind your lids in rhythm between darkness and splatters of soft light. Sometimes light to dark, sometimes dark to light, but always in rhythm, and never quite the same. These are the phosphenes you can manipulate into images if you learn to relax those eyes. Careful though, whatever you think of when the phosphenes dance you're certain to find starring back at you from the darkness.
I always see these bright colours of donuts, and whenever I close my eyes, I get this constantly swirling wave of colours. Its fun to look at. At night time, I also notice that I can see shadows swirling around like they do when I close my eyes, and everything looks almost like pixels. I can see little particles moving and flowing around the place in my vision, especially when looking at white ceilings. I watch them ebb and flow at night, though often the dark swirling effects scare me because they often start to look like things like faces and stuff so I'll often concentrate on something else or close my eyes real tight.
Been watching your videos alot, they're very informative and gives really good insight for viewers. I was wondering if it's possible to get a History vs. Pocahontas? There's alot of "facts" out there that seem to contradict each other and I can't tell who Pocahontas really is and her story
After images used to really bother me when I was a kid. I'd get so frustrated about it because they affected my sight. I wouldn't be able to see past them.
if you shine your phones flashlight from a certain safe distance in a star shape or any pattern and then you if you close your eyes, you'd see that pattern well
I appreciate the accurate imagery in this video! Obviously it's stylistic, but the rod cells outnumber the cones, the brain hemispheres correctly connect to the opposite eyes, and that's recognizably a real TMS coil as opposed to a cartoon 🧲 magnet.
every time i close my eyes and focus on a certain spot, these tiny red blue and green lines show up and expand until it fades away. are they also afterimages?
When I look at the sun through closed eyes, everything looks a little more blue-green after I open them. Does that have something to do with what was described in the video?
I’d like to see TedEd to cover visual snow after this. It’s something I’ve had since childhood and it makes it very hard for me to notice any minute details when observing or drawing. It’s even worse in the dark as everything devolves into a mass of greyish dots that keep farting about
3:42 well I might have some info for this theory. When I was kid, ever since I got the paper 3D glasses from a Spy Kids 3 box I would wear them almost all the time until I grew out of it. yeah later after resting my eyes in a car ride to the mall with my dad while in high school I noticed that after I opened my eyes my vision went green. both eyes were not seeing in the same shade of green either with my right being a green with a tint of blue kinda similar to the classic green from Expo the whiteboard maker brand will my left eye was seeing a green with a yellow tint.
I get negative and positive after images from everything I see. I don't need to manipulate my eyes or stare or anything, they're just always three and they always have been. It's very distracting sometimes.
