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"
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
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
For a while, I was dabbling with esoteric ideas and concepts. One of which is "reading auras". Essentially, you let your eyesight go out of focus while you look at the periphery of a person's silhouette. Over time, you begin to see a halo-like glow around the person that disappears as soon as you try to focus your eyes on it. I did the same thing with my OWN "aura" by placing my hand onto a white board and unfocusing my eyesight while fixating on the tip of of a finger. Over the course of a couple weeks and months, I had amassed a decent collection of drawings it had done of the colours I had perceived and a pattern began to emerge. Essentially, the "aura" that I was seeing was a blurred, negative image of my hand slowly moving upwards. It would seem that looking, while purposely unfocusing your eyesight, at your fingertips will cause your eyes to slowly wander. Eventually, I had negatives overlapping negatives. So that my "outer aura" was basically the same tone as my skin
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
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
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.
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
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.
The real question is why such complicated patterns when rubbing your eyes. I sometimes see fractal-like spiraly chessboards. Are they part of visual understanding or related to how the cones and rods are ordered? Fascinating
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
When I was a kid, I'd get on the roof of our house and soak up some sun, felt great. After laying with my eyes closed facing the sun for some time, I sat up and opened my eyes, I was color blind for a short duration. Could see clearly, just like normal, but no color for a few moments. Then the color would fade back in. Tested it a couple more times but never really bothered with it again. Was an interesting experience.
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.
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.
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.
Pressure Phosphenes-ahhhh, thank you. Such relief to know this term. I rub my eyes with vim & vigour for the kaleidoscope until I'm sure I'll blind myself, I don't care
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 was just thinking about those random pattern I see sometimes and I remember as a toddler that I was fascinated with those abstract patterns I saw when playing with my eyeballs.
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.
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
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.
I've noticed that when I stare at a stoplight and blink, the red light looks green ... luckily I notice it is at the top of the three lights and remind myself that that is where the red light is located & stay stopped. Now I want to know how wavy 3-colour migraine auras work!
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
I noticed something similar with those 3D glasses with the red and cyan filter over each eye. I'd wear the glasses for like a minute, then, when I would take them off, cover the other eye, and look only through the one that saw through the red filter, everything would seem really blue to me through that eye. The opposite would happen with the other eye where looking through the cyan filter would make everything seem more red than usual when no longer looking through the filter. It reminds me of the automatic white balance feature in cameras.
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
I see stuff like this no matter if I had my eyes closed for 5 minutes or 5 hours. If I rub my eyes I see weird blue circles in the corner of my vision.
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.
This is something you've always wondered about but always forget to look up
Always wondered 'why' but didn't find out 'how'
What is the reason to it as well
Wrong
same with that little blurry thing you see in your vision that moves around when you move tour eyes side to side.
Haha trueeee
Finally, someone understands what we've all been wondering!
So true....i was wondering if I have any eye issue...😅😅
And all it took is someone to stare at the Sun and put a needle in his eye.
Me too, I saw those things with my own eyes that I tried to tell someone about it, but no one understands me
I had no idea how badly I wanted to know this
Curiosity is humanity's greatest weapon. I personally think it's really nice of you guys to put much respect and appreciation to it.
0:19 needle-less to say, don't try this at home.
Nice pun!!
I’ve been waiting for this video for like 15 years
Finally something that actually answer something that I always forgot to look up
when i was a kid, i was wondering what are these colors and the small creatures in the eyes. now i can really know
I thought it was superpower. My first memory is telling this to my mom.
@@ireneqq2300 I dunno wat my 1st memory is lol
@@ireneqq2300my first memory was me insisting on telling my mom that I could fly and that I’d done it😭😭I was certain too, I had a vivid imagination
I've always had the habit of rubbing my eyes or blinking at lights to create these weird images, yet I never thought to look up why it happens.
Mee too
Are we just ignoring the fact that Newton stuck a _needle_ under his eye?
Thanks for reminding us lol.
That’s funny
That’s why he’s not alive right now
He couldn't just be normal and rub his eyes, no, he needed to use a needle
That man sure had guts
That's a really cool font.
I wonder if its for sale 😅
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)

So no actual need to generate pressure on the eyes to see phosphenes 🤔
this is the right question to be asking
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

It never worked for me but it did for the characters
3:53 is where it really gets interesting! I've been wondering about that since childhood!
Just yesterday I was searching up all about afterimages and wished there was a ted-ed video explaining it and today I got it in my recommended

It is said that most auras ppl see before migaine is strong currents overwriting the electromegnetic signal in visual cortex
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 Newton guy was just a character 😂😂
I find this channel deeply therapeutic 😅🎉
Thank you algorithm for recomending me this
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.
Finally, the question we've all been wondering since we're little is answered

FINALLY!! I've been wondering about this for so long
This channel teaches more stuff than they do in school
Woah I didn't knew it was a question to asked , but I got the answer. Great !!!
Well I am so early on this video
I’ve always wondered about this. :D
Now I know. I love this channel! Explaining the mysteries of life in a few minutes.
The real question is why such complicated patterns when rubbing your eyes. I sometimes see fractal-like spiraly chessboards. Are they part of visual understanding or related to how the cones and rods are ordered? Fascinating
This video is PHENOMENAL !!!!!
Heyy Ted ed made a dedicated channel for medical science ...
I love watching your educational content.❤❤❤
Right now i deeply passionate about that topic . The primary reason why appealing as well as importantly 😊
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
my goodness our body and function is so remarkable... crazy wild how all this happens
2:32 This part really amaze me, like what??!!! then repeat again to see the effect.
This narrator was incredible

Pressure Phosphenes-ahhhh, thank you. Such relief to know this term.
I rub my eyes with vim & vigour for the kaleidoscope until I'm sure I'll blind myself, I don't care
Did anyone else increase the screen's brightness at 2:33 to test it out?
Thank you! I was wondering why I saw “polka dots” when looking at light! It’s kinda weird thinking about this now-
Omg this video has finally comeeeeee!
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've been wondering this since I was a toddler , until this came out
1:09 Looks like the Windows XP Login screen
those colours are waves that eyes enable you to listen to them just like there are waves that your ears enable you to see them

Basically, a 5 minute video answering the question with "we don't know" 🙂
Trees and plants are covered in photo receptor cells and can tell what colour of shirt you're wearing! New Science!
We watch all your videos at school
So great❤
Looking at green turns it to grey, white balance.
this is so cool, THANKS !!!!

You should get that checked. Seriously.
THEYVE FINALLY DONE IT
To understand this phenomena is way important to me than relativity theory 😄
The bottom line… no one knows BUT GOD - the CREATOR of the Universe and us all!!
Thank You, Lord Jesus!!

When i watched this vid and blinked while watching,i had some after images
I read it from Newton's book itself
I have been searching RUclips for a decent explanation for years, seems like my task has finally ended
Something strange with that flower...
Now someone explain what are those insects that fly in your eye when you see at sky
Very nice to know
Me, curious to see how those colors in your eyes work. Also me completely zoning out when they start using science words
Very interesting
RIP Liam Payne 😓
Just realised my brain is doing what is being explained in the video awesome 😎
stare at coated light bulb for 5 or 10 seconds an turn it of and close your eyes and you will be able to "see" the filament in the bulb.
Or...
Our brain, based on previous experience, predicts what we perceive...
So, we can predict/imagine what might be seen.
I see stuff like this no matter if I had my eyes closed for 5 minutes or 5 hours. If I rub my eyes I see weird blue circles in the corner of my vision.
What are those color I see before having a migraine
Perhaps this will help explain why I sometimes see little yellow dots in my eyes after rubbing them
3:42 well I might have some info for this theory.
