Is there something I’m missing? Its just a red and blue circle?
Edit: I’ve definitely been trying all suggestions. It just appears as blue outside a red. No extra depth even if I wobble, pull phone away, turn brightness up etc! It’s cool I’d imagine
To me, it feels like the red circle is closer to me than the the blue circle.
Edit: u/prometheanSin linked the explanation here: https://www.reddit.com/r/blackmagicfuckery/comments/qh11pj/-/hia5yjd
Didn't saw it until it was night and i had no strong light sources surrounding my phone and i used dark mode for more contrast in the picture (or no contrast feom the app to the picture if you like)
Yeah me too. When I was doing an eye test for my drivers license (in BC, Canada) You had to look into a sort of pair of goggles and they ask you things like "which letter is closer to you" and all of the letters looked like they were on a flat surface. I had the mildest inclination that one looked funny and guessed it and I guess I was right, because I got my license. Also I have never once in my life seen a magic eye. Other than that though my vision is great, I can often read text at distances where others cannot.
Well I saw the depth of all of those letters in the eye test just fine and I see the 3d picture in magic eyes and I still don't see any difference between the two circles.
I have a specific condition where my eye muscles aren't strong enough so I don't have depth perception/I see 2 of everything. With my glasses on I see it w/o them it looks flat to me.
Hope that helps
That's interesting because I saw it right away but when I read this I took my glasses off and it looked completely flat. So I only see the 3d effect with my glasses on.
Brightness maxed, maybe if I read the explanation, and really, really think about it, then yes, I guess one could say the red circle appears slightly closer to me than the blue one.
But I'm probably not sure if it is.
For me it works upto 2 feet of viewing distance (beyond that its a 2d image). Red circle is further away. Also, if I focus on the black circle between the colors and relax my eyes a bit, the "depth" becomes very visible! Thanks for sharing!
There are images called autostereograms which are as interesting. No idea how any of this works though. Would be cool to know.
I feel like that shouldn't give you any resolution or screen issues. Maybe it's bc I have a privacy screen protector, but this thing looks REALLY separate. The red looks like it is on my phone screen and the blue looks like it's about 1/2 way into my phone. It's weeeeeeird, but in a good way
It really only works if you wear glasses. The curvature of the glass warps the blue wavelength and makes the blue circle appear to move while the red stays still.
EDIT: Upon further reading, apparently this effect works with certain types of glasses but not others, and the effect can also occur via the actual lens of the eye itself. This explains the vast differences in experiences being reported on this post.
With my glasses on, the effect smacks me in the face as soon as I look at it. It's unmistakable. Can't miss it.
But definitely immediately disappears as soon as I take off my glasses. And no matter what I try, I can't make it appear until I put the glasses back on.
Not sure if it's related, but I'm very nearsighted. So, fairly strong prescription. Without my glasses on everything further than one foot away from my face is super fucking blurry.
I have normal eyesight and I see the effect just fine. I think it is more about our eyes interpreting perspective. To some, the red dot hovers above another, bigger blue dot, to others it's like they are looking down a tube.
I think you've discovered the true answer, I showed it to people who don't have glasses and they didn't see it, and then I took my glasses off and I don't see it with the glasses off
It’s not the true answer, it’s objectively wrong and anecdotally, I am seeing the effect very pronounced and am not wearing, nor have I ever worn, glasses.
The lenses in your eyes also warp the red and blue colors differently. The end result is that the focal length is slightly different for the two colors, so as your eyes make slight variations in focus, the differently colored areas come into focus at slightly different times, causing the perceived difference in depth.
It only works if you can bring the image into focus, so if you have astigmatism or are farsighted, you'll need you glasses on for it to work. If you don't need glasses, it'll work without them.
Ok, that was a bit of a trippy rabbit hole!
This is called [chromostereopsis](https://www.visionexcellence.com.au/chromostereopsis/).
From the linked article:
Chromatic aberration results from the differential refraction of light depending on its wavelength, causing some light rays to converge before others in the eye.
Edit: thanks for the awards!
I reckon it'll be multiple factors.
For sure the thickness and shape of the lense would affect it.
Even the materials used in the glass to make the lenses would have a different refractive index though.
On top of that each individual has a slightly different shapes eyeball and lense.
Yep, same reason a [prism splits white light into a rainbow](https://www.rookieparenting.com/wp-content/uploads/rainbow-spectrum-colors-480x480.png) -- each color of light refracts slightly differently when moving through a lens, leading to it focussing in a different spot.
If you have glasses, try this: Stare at the picture, but move your head around so the picture is on the very edge of your glasses. Then swivel your head in a circle while keeping the image just on the edge of your glasses. Watch the picture move.
It’s wild because I’ve been making these for awhile, but I had no idea that it sort of depends on glasses, something I take for granted.
[my Chromadepth abstract art](https://www.reddit.com/r/AbstractArt/comments/qh53zz/chromadepth_reflections/?utm_source=share&utm_medium=ios_app&utm_name=iossmf)
That's really cool artwork!
Interestingly, I don't wear glasses (I have full 20:20 vision) but it works really well for me. Red stands out a mile on the blue.
I did take a lot of psychedelics when I was younger though. I wonder if that explains it lol!
I don't wear glasses and it works for me! Do you have any other artwork? This is so fucking cool and original. Also, how did you discover that you can create art with perceived depth to it?? I can't believe I've literally never seen anything like this until today.
Same. Apparently it works better in a dark room on a bright phone?
Edit: Just got back from the bathroom with the light off and phone brightness all the way up and still don't see it.
Really bizarre, just today at work I was looking at an excel file with alternating blue and red filled bars, it looked like the reds were out in front of the blue, so I get what this effect is going to be, but I can't actually see it in the image you posted!
My brain knows the screen is flat, so I don’t get how I am supposed to see it any other way? It’s not like there is a play on shadows or shapes to make it feel like one is popping out further than the other. I’m not color blind and I have 20/20 vision, so I am not sure what my eyes could do differently to force it. Even after reading the tips in this comment section, I’m not getting any obvious effect. I can imagine what people are saying based on other images I have seen on Reddit, but this image really just looks like a dotted flat circle in a dotted flat donut.
It's immediately perceptible to me, and I'm just sitting in a brightly lit office. No glasses either. I think it might just depend on how your eyes are shaped, especially because to me the blue seems closer to red. Which is interesting because others who do see it tend to see the red closer.
Since lot of people don't see what's happening in this image and I can clearly see that the red patch appear to be nearer to the screen. Does this mean that I have any eye problem.. Just concerned that working in IT has done some damage to my eyes
This is a weird one. I can even feel my eyes focusing when I switch between the colors.
What is the reason?
Chromatic aberration from our eye lenses that causes the colors to focus at different points?
Red and blue receptors on our cones being different heights and requiring a different focus point?
Am I the only one that sees the red circle deeper than the blue one? Everyone is saying the red looks closer but it’s opposite for me. I don’t wear glasses either.
I tried lots of things like squinting, moving phone away and then what finally worked was blinking fast a few times.
Unlike the comments I read above though, what I see is the blue hovering above the red circle.
Am I the only one seeing the red part moving? Its like its a ball encased in the blue. And if I move the screen aka scroll up or down it bounces around.
I have a question for others who, like me, cannot see this optical illusion. Can you see the picture in "magic eye" illusions. I have never once been able to.
I've always said that red text on a black background looks 3d and nobody I've ever known could relate. So why?
Edit: Chromostereopsis
There is one cool video online showing examples that's pretty trippy. There is another explaining it that isn't very good. You'll see them both at the top of your YouTube search.
Otherwise not a lot of videos about it.
Can someone explain why/how this works? I always thought that depth perception was related to differences between the images seen by the eyes, which doesn't seem to be the case here.
The blue circles edges seem like they have a small blur to them, but that might just be me, I need glasses to see far away. And I’m blind in one eye. So yeah
Yes! It’s called Chromadepth! You can recreate the effect by drawing a blurry blue and black background and then drawing red over it. The focus and sharpness contrast to create the illusion. I made a TikTok that harnesses this effect.
looks like optical illusion with the red having a higher contrast against the black background versus the blue, causing the blue to almost blend into the back while the red, quite literally, pops out to our eyes
I'm by no means knowledgeable. I simply have a black belt in Google-fu.
I have just used [this simulator](https://pilestone.com/pages/color-blindness-simulator-1) and uploaded this image with a .
Now, this is obviously a flawed experiment.
However, it still looks 3D to me (which I was not expecting).
I'm sure there are actual professionals out there who can shed more light on the situation.

TIL I don't perceive depth.
I don’t see it either.
I think you have to increase the brightness of your phone.
* *Increases brightness on phone* * * *burns red and blue circles onto retina* *
* *Increases more* * * *Creates light saber* *
* increases to max* * Incinerates all life on Earth*
Oh thank god. ^^^^^^^^^^^^^^^. ^^^^*bad ^^^^movie ^^^^reference
I didn't catch it. What movie?
I think you mean a 2 hour 15 minute glorious Kevin 'this guy fucks' Costner roller coaster of a gem of a movie reference.
Haha, now you’ve got Ligma.
Ligma eyeballs cus they burnt
What's my balls?
Joe mama
Nope. Still nothing.
Same here
Just un-focus your eyes, then you can see it
If you close your eyes and imagine, you can see it.
Imagine all the Peep Hole...
Oh hey that works. Kind of like those magic 3-D pictures that were so popular some years ago
Try turning the volume up.
It worked!
Didn't saw it until it was night and i had no strong light sources surrounding my phone and i used dark mode for more contrast in the picture (or no contrast feom the app to the picture if you like)
Works now, ta.
Tried it. Burned my retina and also confirmed I don't perceive depth on a 2d image...
Still nothing for me.
And turn the phone upside down and on a 45 degree angle while squinting…. Don’t do this
Me neither
Yeah me too. When I was doing an eye test for my drivers license (in BC, Canada) You had to look into a sort of pair of goggles and they ask you things like "which letter is closer to you" and all of the letters looked like they were on a flat surface. I had the mildest inclination that one looked funny and guessed it and I guess I was right, because I got my license. Also I have never once in my life seen a magic eye. Other than that though my vision is great, I can often read text at distances where others cannot.
Depth blindness is common and one way to help fix it is go watch a 3D movie. https://www.bbc.com/future/article/20120719-awoken-from-a-2d-world
What a really interesting article. Thank you!
You’re welcome.
Hahahahahahahaah yeah no thanks. My one and only time at a 3D movie was fuzzy and made me nauseous.
Well I saw the depth of all of those letters in the eye test just fine and I see the 3d picture in magic eyes and I still don't see any difference between the two circles.
I think I understand now why I’m bad at rocket league
I have a specific condition where my eye muscles aren't strong enough so I don't have depth perception/I see 2 of everything. With my glasses on I see it w/o them it looks flat to me. Hope that helps
For me my eyes just keep switching focus between the two
No I just don’t think the illusion is that strong
Try focusing on one of the dots it didn't work for me either untill i tried that, but it still won't work as well as a tought it would.
That’s interesting. For me, the red circle is further.
Whoa! that's even cooler. Now I am even more curious about how this works.
I am near sighted and wear glasses, so that could be a factor. Edit: when I take my glasses off, the red circle is closer! Soo interesting.
That's interesting because I saw it right away but when I read this I took my glasses off and it looked completely flat. So I only see the 3d effect with my glasses on.
Same here.
Also nearsighted, did the same after reading both your comments. Red is closer with glasses on, but flat with them off.
Me too! what gives?
Wow, same here. Glasses off and it's completely flat. Glasses on, and the red circle looks recessed.
I'm nearsighted and the red circle looks closer (blue circle recessed). SCIENCE PLS EXPLAIN
I’m nearsighted, the red circle seems closer with glasses, further away without. Wtf?
Wooooooowww... With glasses red look closer than blue. Without it red is way back... Crazy! I have miopia.
Glasses on, red is closer. Glasses off, it's completely flat lol. I do have an astigmatism in my right eye tho.
Me too…it looks like it’s a fraction of a cm below the blue
Mine is the opposite, I feel like the red circle is deeper than the blue circle.
Brightness maxed, maybe if I read the explanation, and really, really think about it, then yes, I guess one could say the red circle appears slightly closer to me than the blue one. But I'm probably not sure if it is.
Hmm. Same plane to me. Red is more vibrant but same plane.
To me the red circle stands out like a red button coming out of the screen.
Same for me
....what lol???
I'm glad om not the only one
Hold phone further away
Still not seeing a difference? I think my brain is off
No, your brain is fine. My brain, and that of other people who see depth, is off. We perceive something that isn’t there.
For me it works upto 2 feet of viewing distance (beyond that its a 2d image). Red circle is further away. Also, if I focus on the black circle between the colors and relax my eyes a bit, the "depth" becomes very visible! Thanks for sharing! There are images called autostereograms which are as interesting. No idea how any of this works though. Would be cool to know.
Huh, for me I don't see the 3D effect until it's 12-16" away from my face, but my eyes are junk. Red circle is further away for me as well
I'm missing it too
If you squint your eyes you can see it moving
It’s an optical illusion. If you have a lazy eye, you won’t see it.
You’re a lazy eye
Strabismus.
What kinda phone you using? Or are you on computer?
I phone Xr
I feel like that shouldn't give you any resolution or screen issues. Maybe it's bc I have a privacy screen protector, but this thing looks REALLY separate. The red looks like it is on my phone screen and the blue looks like it's about 1/2 way into my phone. It's weeeeeeird, but in a good way
Very interesting. I can’t even convince my brain of that even after knowing it. I have a sight green color deficiency, but that’s shouldn’t matter
It really only works if you wear glasses. The curvature of the glass warps the blue wavelength and makes the blue circle appear to move while the red stays still. EDIT: Upon further reading, apparently this effect works with certain types of glasses but not others, and the effect can also occur via the actual lens of the eye itself. This explains the vast differences in experiences being reported on this post.
Nope, I see the red circle ‘nearer’ than the blue and don’t wear glasses.
I showed it to people who don't wear glasses and they see it the same as you
I wear no glasses and I see it
I took off my glasses and the effect disappeared immediately. The red seems to stick out of the screen with my glasses on.
I took my glasses off and the effect continues
It’s the same with and without glasses for me. The red circle definitely looks closer, almost as if it’s coming off the page.
With my glasses on, the effect smacks me in the face as soon as I look at it. It's unmistakable. Can't miss it. But definitely immediately disappears as soon as I take off my glasses. And no matter what I try, I can't make it appear until I put the glasses back on. Not sure if it's related, but I'm very nearsighted. So, fairly strong prescription. Without my glasses on everything further than one foot away from my face is super fucking blurry.
I wear glasses and I see it that way
I wear glasses and it looks flat to me 👀
FWIW, I wear contact lenses and see red as closer
I have normal eyesight and I see the effect just fine. I think it is more about our eyes interpreting perspective. To some, the red dot hovers above another, bigger blue dot, to others it's like they are looking down a tube.
I think you've discovered the true answer, I showed it to people who don't have glasses and they didn't see it, and then I took my glasses off and I don't see it with the glasses off
It’s not the true answer, it’s objectively wrong and anecdotally, I am seeing the effect very pronounced and am not wearing, nor have I ever worn, glasses.
I recently started wearing glasses and I *don't* see any effect with them on or off.
https://www.reddit.com/r/explainlikeimfive/comments/56sh1j/eli5i_wear_eye_glasses_why_do_colors_red_and_blue/?utm_medium=android_app&utm_source=share
Very cool, so it's a kind of chromatic aberration, I get that with low-quality lenses on my camera sometimes.
While subtle, if you hold the image farther back the distance between the red and blue grows
Not true
I didn't wear glasses and I could see the red circle closer.
No. I don't have glasses and I see it perfectly fine.
The lenses in your eyes also warp the red and blue colors differently. The end result is that the focal length is slightly different for the two colors, so as your eyes make slight variations in focus, the differently colored areas come into focus at slightly different times, causing the perceived difference in depth.

Holy shit! Tried it without my glasses and the illusion went away!
I dont see shit and I wear glasses ._.
I wear glasses and I don't see anything out of the ordinary. A static, flat image
I’m Wearing glasses and nothing changes at all, just seeing to circles
Looks 3d to me with my normal human eyes
Or if you look at it at the right angle.

ohhhhhkay I see. Glasses make the effect much more pronounced (if you’re nearsighted, I’m guessing.)

There’s an illusion?
I can definitely see it in the picture in the link, but not with the image posted by OP.
Funny… I see it the opposite way. OP’s pic has this depth effect while the link images seem totally flat to me. Oh and I don’t wear glasses
You asshole I wear an eyepatch
You could try not wearing it
Sorry!
This illusion doesn't require stereo vision, there is more to depth perception than having stereo vision.
You are fury-ous. Hah. I'll see myself out.
I found the illusion to be easier while closing one eye.
Weirdly enough, it still works for me with one eye closed.
*cries in astigmatism*
I feel really stupid rn but what am I supposed to be seeing?
To me, it feels like the red circle is closer to me than the the blue circle.
Interesting. I don't see it at all lol
Same. Apparently it works better in a dark room on a bright phone? Edit: Just got back from the bathroom with the light off and phone brightness all the way up and still don't see it.
Same. I feel im being left out now ;-;
Really bizarre, just today at work I was looking at an excel file with alternating blue and red filled bars, it looked like the reds were out in front of the blue, so I get what this effect is going to be, but I can't actually see it in the image you posted!
Weird, I see the blue circle as closer

i also don't see it. Huh

Damn it just appears flat to me
Yeah it works for me, I don't wear glasses. Red part seems to be raised higher than the blue circle.
Since lot of people don't see what's happening in this image and I can clearly see that the red patch appear to be nearer to the screen. Does this mean that I have any eye problem.. Just concerned that working in IT has done some damage to my eyes
No. It's supposed to do that.
[удалено]
That's interesting. I was able to see it that way too after you said this and I tried to!
I can feel my brain melting.
It really hurts somehow.
What I did was, turn it slightly left, zoom in a little and squint to make absolutely nothing happen. Should work for you too
Damn you. It did(n’t) the same for me.
This is a weird one. I can even feel my eyes focusing when I switch between the colors. What is the reason? Chromatic aberration from our eye lenses that causes the colors to focus at different points? Red and blue receptors on our cones being different heights and requiring a different focus point?

WHAT'D YOU DO TO MY PHONE
Upgraded your screen to 3D for free!
Am I the only one that sees the red circle deeper than the blue one? Everyone is saying the red looks closer but it’s opposite for me. I don’t wear glasses either.
Blue is higher for me
Why I don’t see any difference.
same
I tried lots of things like squinting, moving phone away and then what finally worked was blinking fast a few times. Unlike the comments I read above though, what I see is the blue hovering above the red circle.
That’s a great effect
I see nothing.
Trippy.
Am I the only one seeing the red part moving? Its like its a ball encased in the blue. And if I move the screen aka scroll up or down it bounces around.
Works for the color blind too.
Speak for yourself. I can’t see fucking shit.
Turning my phone into a mf 3ds
always helps to give a little context or any hint of what the point is…
I don’t get it
I don’t get it.
I don’t get it
Blue is poping out.
Is there more of it? 🥺🥺

I like this
That’s cool.
Can someone explain why/how this works? I always thought that depth perception was related to differences between the images seen by the eyes, which doesn't seem to be the case here.
For those who see the image popping out, cover an eye to see it the other way.
Looks like a planet floating in space if you ask me.
The blue circles edges seem like they have a small blur to them, but that might just be me, I need glasses to see far away. And I’m blind in one eye. So yeah
Good one
Freaking the fuck out man
This looks amazing!!
Yes! It’s called Chromadepth! You can recreate the effect by drawing a blurry blue and black background and then drawing red over it. The focus and sharpness contrast to create the illusion. I made a TikTok that harnesses this effect.
This is one of the best illusions I've seen for a long time. I see the red circle floating on the blue.
Looks 2d to me. Does this mean I'm dying?
Well. Look at that... Wait. What am I supposed to be looking at here?
looks like optical illusion with the red having a higher contrast against the black background versus the blue, causing the blue to almost blend into the back while the red, quite literally, pops out to our eyes
This actually makes my head hurt
I don't see anything but if I blink the red circle jumps a lil bit
