At a local bar they had a game machine, and if you got a high score on any of the games, your tab for the evening was free.
One of the games was a "spot the differences" between two pictures with an ever decreasing timer for each round. Using this trick I was able to easily surpass the high score, and garner a crowd watching me perform this mind numbing feat.
Probably my peak fame right there.

- soco 2y agoI can't overlap the images to save my life - they get like halfway there and that's it...
- ThrowawayTestr 2y agoTry on mobile, it's easier if the images are smaller.
- pivo 2y agoWow, yeah it happened immediately for me on mobile while I couldn't get past half way on my monitor. Thanks!
- physicles 2y agoAre you crossing your eyes (focusing nearer than the object) or diverging them (focusing past it)? Diverging is a harder skill to learn.
- soco 2y agoNot even sure which one I should try :) but yes tried both to no avail. Maybe it's just not something to achieve in the first try...
- wruza 2y agoFor crossing just focus on your finger and then remove it. Looking far away may be harder, and afaik it’s near impossible to look “past infinity”, iow pictures must be less wide than the distance between your eyes. Btw these two methods aren’t equivalent in watching stereograms. If you look at one and see something but it doesn’t really make sense, then it’s probably the opposite chirality. Personally I hate the crossing method because it makes your eyes feel strange for a while.
- unkulunkulu 2y agohow I approached crossing: first practice just crossing your eyes and observing how every object has two images in this case and when you slowly “uncross”, they merge back into one. you can use anything in your surroundings. then for the stereogram you do the same, observe the out of focus edges of the left and right pictures, then slowly uncross until left and right image occupy the same spot as though they were the same object. now its out of focus, but one (ok, actually three, because there were two, you “doubled” that by crossing, then merged two of them. but ignore the other two and focus on the merged pair) sometimes you will merge images of the same picture, in this case you are just back at your normal vision, repeat :) then you try to keep them overlapped and focus the vision, try to “believe” that you are really looking at a single object.
- titzer 2y agoDiverging is definitely harder, and might be out of focus. To keep in focus I found it easier to focus on the right image and then cross my eyes, rather than staring in the center and then staring through the screen into the distance while trying to make them line up. I used to not be able to do the "magic eye" 3d images until recently, and this trick is pretty handy.
- biomcgary 2y agoIs diverging harder? I find it easier. Maybe it is from long ago practice on stereograms, but I'm curious if it could be due to neurological/physiological differences.
- grumbel 2y agoCrossing is easier because you can simply hold your finger in front of your eyes and look at that for practice. Diverging requires you to look past the image, meaning you have nothing to really look at, which makes it difficult to figure out what your eyes are even supposed to do. Those stereograms aren't helping much either, since they look like nothing until you get it right. With cross-eye you have instant double-vision that you just need to align. Cross-eye also works across much larger distances, diverging fails when the images are too far apart.
- leni536 2y agoIt depends on the image. If the two images are too far apart then it could require your eyes to diverge, and not to just converge slightly less. That might be impossible.
- BenjiWiebe 2y agoDiverging is way way easier for me, but I am positive that's because of the 10's of hours (at least) that I spent staring at magic eye images as a child.
- paulsmith 2y agoMy whole life I've been doing stereograms by diverging, but I couldn't get the three images in the post (the pairs would get closer but never fully overlap), so I tried crossing based on your comment. It was way easier than diverging (obviously, since I couldn't do it otherwise), but it took me a few tries, because I think it's actually /too/ easy to cross your eyes compared to diverging - I was way overshooting when I crossed my eyes. The trick was to notice this, and then control the un-crossing until they lined up.
- waffletower 2y agoThat happened to me too but I persisted and eventually succeeded. I think I needed to cross my eyes slightly more than I was initially. I have been diagnosed with a minor eye convergence issue which makes it difficult to focus on near field objects in motion -- gaining this superpower was difficult but I did it without a headache thankfully.
- PaulHoule 2y agoIt's like https://triaxes.com/docs/3DTheory-en/522ParallelCrosseyedviewingmetho.html https://triaxes.com/docs/3DTheory-en/522ParallelCrosseyedvie... which some people struggle with, somebody posted a https://en.wikipedia.org/wiki/Autostereogram https://en.wikipedia.org/wiki/Autostereogram to HN yesterday which some people get and others don't. (That's different from the "cross-eyed stereogram" because one of them involves having two images and the other one has one image with two images hidden in it)
- mhitza 2y agoI can understand why it's hard for some. I've landed on that wiki page a while ago and couldn't figure it out. Then found a similar thing on an itch.io page that was easier for me to figure out. In these later examples (starting with the easy puzzle of the OP, and your 3d examples), I find that I do the process in two stages. Unfocus my sight until the third image shows up in the middle at the correct size (as a blurry mess). Then try to focus the center image.
- PaulHoule 2y agoWhat's more a lot of people (maybe 20%) don't benefit from things like https://www.reald.com/ https://www.reald.com/ which is one reason why stereo movies have struggled. (That plus some people get sick... Having both a flat and 3-d movie in two different theaters comes across as money grubbing to the consumer but it is really a money sink to the theater.)
- nis251413 2y agoYeah that's me. I lack stereoscopic vision so such tricks or 3d glasses etc do not work.
- tartoran 2y agoI have a big problem crossing my eyes too while having no problem with the parallel view way seeing stereograms. I am actually going to stop trying as my eyes started to hurt.
- rwmj 2y agoI spent far too much time as a twenty-something generating autostereograms, which seems to have trained my eyes. I was able to "cross" the images on this page very quickly.
- KPGv2 2y agoNB autostereograms require you to move your eyes away from each other, the opposite of crossing them. To put it another way, crossing your eyes is what your eyes do when you're looking at something close to you, while the opposite is when you're looking far away. Which is why for ASGs people advise you to look past the picture. Or why you bring the pic close to your eyes (so close that you basically have no choice but to look beyond the picture)
- iforgotpassword 2y agoYou can easily generate inverted ones that require crossing your eyes to appear properly, but they don't look as nice since they pop out instead of going into the screen/book.
- BenjiWiebe 2y agoEver since I was a child addicted to the "magic eye" stereogram books, I've always diverged (not crossed) my eyes for spot-the-difference puzzles. Also, if you're doing it on a piece of paper, hold a pen in each hand spaced right so you see the middle (3rd) hand in the middle combined image, and move both hands in sync to circle all the differences. Kind of a cool way to point them out to someone else. The difficult puzzle took me about 10 seconds here since I was looking for more than one difference. I saw the first difference in about 1 second.
- antihero 2y agoIs that the crossy-eye porn?
- itishappy 2y agoBetter known as Magic Eye, but yes.
- jeffhuys 2y agoDon’t CROSS them. Relax them, like you’re tired and can’t focus on a computer screen.
- jeffhuys 2y agoAlso keep the size low. If you’re having a hard time at 20cm from a 4k 30” monitor, it won’t come easy. Zoom out.
- hk__2 2y agoThere are two methods, either you cross them either you do like you’re describing.
- arka2147483647 2y agoYou can actually do it both ways, but which is easiest for whom is different.
- jjk7 2y agoIt helps me to see the depth and then properly focus to cross them very slightly to start, then as I see the image my eyes adjust to pull it in focus properly.
- emmelaich 2y agoYep, I didn't need to fully cross them. Which is good, because that is painful.
- raffraffraff 2y agoI cross them first, then slowly relax them and as the two pupils start to move slowly back out I tell myself that the middle image is further away and "real".
- Taek 2y agoYou might be too close to the screen.
- Tempat 2y agoIf you mean literally you can only bring them half way together, try just moving twice as far away.
- adamc 2y agoYeah, me either. My eyes really resist it. And after trying it a few times it messes up my focus for a bit.
- lr4444lr 2y agoTreat it like a "Magic Eye" photo and just relax your eyes to a further focus point.
- nadis 2y agoSame! I feel like I can get a fleeting moment and then it's gone. I swear I could cross my eyes when I was a kid - I wonder if with practice it'll come back or if I'm just old and this skill I didn't-know-I-wanted is lost
- smusamashah 2y agoThere is a way to help yourself. Put the pair of images in front of your eyes. Bring your finger between your face and the image. Now look at your finger. Move your finger back and forth. While doing this, notice that at a particular distance, the images in background will perfectly overlap each other. That's your moment. Pull out your finger and look at that image. --- Should take lot less tries to learn doing it without finger. I have taught cross eye to my siblings and cousins using this method. But if you always need finger to focus it's fine.
- thayne 2y agoI tried, this, and I can get it to overlap in the background, but as soon as I take my finger away, I lose it.
- OJFord 2y agoYou may have a very slightly 'lazy eye' (I do) - it can be a lot less extreme (not at all noticeable to others) than the pointing-completely-different-directions that people imagine, and iirc is highly correlated with astigmatism. Optician used to tell me to work the muscle by following my finger to my nose, trying to maintain a single image. At a certain point it will snap into two - the 'lazy' eye has given up and drifted slightly - the goal is to get the finger as close as possible. Obviously if you get very close or all the way, that's 'cross-eyed', but I just can't do it.
- adriand 2y ago
- hgomersall 2y agoWhen it works you get what seems like 3 images with the middle one showing the differences; you can then relax and peruse the middle image at will. I guess all the practice with SIRDS as a child probably helps.
- loco5niner 2y agoHere's another trick: open the image in a browser, then zoom out. The smaller the image (up to a point and you can find a sweet spot) the easier it is to get them to overlap. Once you've got it, slowly zoom in a bit at a time, re-acquiring the overlap at each stage.
- prashnts 2y agoWhat really helped me was doing some sessions with an Orthoptist to reeducate my eyes. I used to see double when stressed sometimes and could never imagine to converge/cross my eyes and retain focus. With the reeducation I was able to see the Impossible one in focus after a couple tries.
- d3VwsX 2y agoI had to see an eye doctor at the hospital when I was ~7 and I got to do some exercises, but I never learned to cross my eyes, and then it was like it probably wasn't very important since I did not have to go to the doctor again and no one mentioned it so I just went on with my life and it seems overall like not being able to cross my eyes is not a huge problem. But I guess it may be connected to my complete inability to see 3D effects or figure out how to see anything in the images in the article.
- OzFreedom 2y agoSame as in autostereogram, the trick is to look to the distance. Close your eyes and imagine a mountain far away or some distant object, notice how your eyes adjust to see it. Open your eyes and try to look at this imaginary mountain while the image is in front of you. When you see the third Image, treat it as if its a distant 3d object somewhere on the horizon.
- glxxyz 2y agoWhen I brought an early autostereogram in to school in the early '90s my high school Physics teacher refused to try it as he thought it sounded impossible. He thought we were all in on it as we 'got it' one after another.
- Ericson2314 2y agoThat was me at first. I think the "cross eyed" phrase is a bit ambiguous. What I ended up with (I think) is a focal point not closer than the screen but farther than it. My eyes didn't want to do it at first but then they did. What is weird about it is the focusing and focal point are out of sync --- my brain can do it but the weird feeling is one of "gosh, this thing is a lot closer than it should be" where "should be" is based on focal point, and "is a lot closer" is based on focus. Don't want to do this too much, feels like I could easily decalibrate my brain for real life lol.
- nwatson 2y agoThat focus-farther-than-the-page works (for most people) as long as the distance between the (center of each of the) two images on the page is smaller than your interpupillary distance. In this case the left eye will see the left image, the right eye the right image, in the overlaid resolved image. For most people, having the images resolve in front of the plane of the page such that in resolved overlaid image the right eye sees the left image, and the left eye sees the right image, will work ... and it can work even if the images are farther apart than the interpupillary distance.
- Ericson2314 2y agoThanks, that is nicely explained --- you finished the thinking I had only started! Are the eyes mechanically capable of pointing outward (so the interpupillary distance is not longer a constraint)? If so, is the problem then neurological not mechanical (brain doesn't want to send signal so they do that)?
- sundarurfriend 2y agoThis helped me more than any other comment here, but I've still not got them fully overlapping. (Probably just a matter of practice/trials at this point, to be fair.)
- hoppp 2y agoWorks for me, I see 3 images if I try hard and the differences pop out
- smusamashah 2y agoI have just figured that using kitchen towel rolls as a binoculars is the easiest way to do a parallel eye on these kind of images. Try that. Hold the rolls like binoculars where right roll is pointing at right image and left is at left image. It's like a DIY VR headset where your brain/eyes only gets two same looking things to focus. No outside noise.
- duxup 2y ago>Probably my peak fame right there. My son and I always make jokes about everyone's 5 minutes of fame. Some random person on the jumbotron at a sporting event "Yup, there's his moment, it's over now." At least yours got you something ;)
- klondike_klive 2y agoOne of my dad's sayings when somebody in a film delivered a line and then disappeared was "6 months rehearsal for that."

- throwaway743 2y agoJust got a funny visual of someone going crosseyed and focused on overcoming a challenge in front of them, with a crowd of people cheering them on.
- lxe 2y agoI was about to post this same exact post :) Was the high score holder on there for a few years.
- sschwa12 2y agoThis is my peak fame as well. I had the high score on every one of these I've played using this method. My friends were always try to figure out how we could make money doing it... The game is usually called 'Photo Hunt'
- bluedino 2y agoThose Megatouch systems run Linux! Lots of fun messages to read on the credits screen or when you reboot them.
- hoistbypetard 2y agoI haven't seen one in several years, but they always used to run Red Hat, based on the boot screens.
- lenkite 2y agoFailed to perform the technique despite multiple retries, but didn't have any issues spotting differences the normal way for all except the impossible mode - which just felt like it would be tedious. My usual method is just to brute-force linear scan from left to right, top-to-bottom. May not be elegant, but it works.
- deleted 2y ago[deleted]
- redcobra762 2y ago...except as you say, it didn't work. The "eye-cross" trick gave the answer on the impossible one in ~10 seconds.
- NoMoreNicksLeft 2y agoThe impossible one was sub-2-seconds for me. I had to do it over to make sure it wasn't more than one difference... Makes you wonder if the kid he was talking about had a lazy eye or crossed eyes or something.
- hgomersall 2y agoThe impossible one was quite tricky, but I did find I was able to relax into the image and take my time. Probably took about 10 seconds.
- deleted 2y ago[deleted]
- ElijahLynn 2y agoTook me about 10m total to get it all the way to impossible mode. I think you can do it!
- K0balt 2y agoFun fact- when I was a teenager, my friends and I set up a stand in a local mall selling those “magic eye”posters. We made bank for a few months. But, there are actually a lot of people that medically cannot use the technique, or at least for whom it is extremely difficult or less vivid. Severe astigmatism, (obviously) blindness in one or more eyes, and certain attention deficits or fidgety types often have a difficult time. I, on the other hand, 37 years later,am basically permanently crosseyed from the experience lol. It somehow became a resting state for me from all of the practice, so I’m always doing it on any kind of repetitive patterns, and even “successfully” on random ones which does some really weird stuff in your visual cortex.
- 14 2y agoSadly I was never able to gain anything from this trick other than my kids admiration. Often times kids menus at restaurants will have a spot the difference and I can see everything instantly doing this. Impressive to a kid but this girl in the video was obviously doing the same thing and does not impress me.
