Here is something you don’t see every day. In my view this illusion is totally mind-boggling. We all know how Ponzo illusion works, and why this phenomenon occurs, but in this particular example it’s really hard to settle that both red lines are exactly the same – I measured them. Still, I can’t deal with the fact that the further line isn’t little bolder and little longer. Can you convince yourself? How can “what we see” and “what our mind is telling us” exist in harmony? Share you thoughts, please.
My flu isn’t gone yet. I’m little better, but have really strange headache. When I try to move my eyes from one corner to another, intolerable pain strikes. If I want to look at something left of me, I have to close my eyes, turn my head and then open them again. Same goes for any other direction except straight forward. The good thing about having so many readers, is that some you may be doctors. Before I go to see my own doctor, what would your diagnose be?

Nice modern version of an old illusion. First?
It’s easier to see if you fog your vision a bit (don’t know how to describe it in another way).
But this one’s certainly well done.
I think the illusion is somewhat increased by the fact that the right line is slightly higher than the left.
ha! thats neat! this is definately the best ponzo illusion ive ever seen!
btw, first comment.
Awesome illusion, sorry about your cold. I’ve had headaches like that, they’re the worst…

checked it with photoshop….
the right line is a little bit bolder through image-resizing but they are both the same lenght oO
it all has to do with depth perception. the depth in the ‘hallway’ emphasized by the tiles. if you have 2 identical objects, one close by and the other further away, the latter one seems smaller. that’s logical, because the further away, the smaller stuff gets. if you have 2 identical things and you lay them on a picture with depth, one on a spot that is further away (in the picture) it should be (in real life) smaller. because that isn’t the case, it looks bigger. especially with these big depth differences. the red stripe closer by is barely the size of one tile, the other one covers the total length of 5 tiles. so your mind tells you that the further one has to be a lot bigger, so it looks bigger.
I think…
IMHO, i’m not a doctor.
However, if it is just when your eyes physically move (head movement as a whole notwithstanding) I would suggest your REM stage is lasting for far too long, perhaps stay up longer? ;-) Or you’re playing to many games with a VR Headset.
Well, I can convince myself that the lines are exactly the same. Perhaps it is because I overlaid (um, spellcheck that?) a grid on top of the image after seeing what it was.
YEAH!!! im the first person to comment also i recommend not moving your eyes
Indeed, its quite a good one that!:)
Thanks for posting even though you’re ill :) and i know the exact feelign that you are on about with your eyes! … if i move my eyes now i can imagine the pain because i’ve had it before!:P …. of course, sleep and plenty of fluids is the best option :)
Yeah!!! im the first person to comment! WOOHOO
Love it!
To see the same picture with out all the extra stuff go here,
Thewtf.org/REDLINE.psd
As I said before, it’s all about perspective, man…..
euh.. i just don’t see any illusion.. where should i look?
This has freaked me out. I was convinced they were different sizes. Weird
I had the flu recently, too. I had a head-splitting headache and similar conditions with my eyes.
Bed-rest helped me the most. I also had a fever so I wrapped myself in a few blankets and slept for about 36 hours. Also, get carbs and constant fluids in you. Advil or Tylenol help too, and the doctor will probably say the same thing.
Wow this is diffrent normally it looks taller but this one is really bolder, its just the way the brain works. Hope you get better soon take some pain killers, you may have high blood pressure near the eyes or damaged a vain/vein.
This is like you say a great example, you can actually ’see’ the change in focus/adjustment of your eye when you look from one to the other. fantastic!
First comment? Dubious. This is a good one. In spite of your flu you’re putting out some very good illusions lately. Get well soon! Wait…I mean now.
(I personally love nyquil by the way and tea+honey works miracles as well…though I’m probably regurgitating things you already know.)
As far as what we see and what our mind is telling us I think that if we did not perceive these as different lines we would have no depth perception and wouldn’t be the same species…and probably would have died off because we thought those lines were the same but one was actually closer and killed us :-P
I have no idea what I’m saying…or rather I don’t think I verbalized it well.
I guess what I’m trying to say is that these optical illusions are a sort of regression to our abilities of perception. They would not be so obvious if we had less advanced visual systems
PS it sort of looks more believable with one eye closed :-)
this one is crazy cool, I can usually see that they are the same, but I can’t filter out those tiles.
I’m no doctor but I’ll bet you have sinus pressure on a nerve leading to you eyes. Hydrate and rest. feel beter soon
Headaches can be worsened by eye stimulation, as light, eye movement, reading, etc. If you have a flu it’s normal to have headaches… so it seems no to be nothing to worry about.
Anyway, if it persists, see your doctor. ;)
btw, great illusion, although not original.
what the heck this tottally sucks there is no illusion to this what so ever. LAME!
I measured these lines as well but I can’t get over the fact that the second line isn’t actually bigger! Maybe because the picture uses a real life background?
If you put your hands in front of the tiles, the red lines are obvious the same. If you pull your hand back, the right line “grows” :) Weird…
You have a migraine. Go see your doctor, because there are an infinite number of reasons why people get them.
I like the illusion. I’m no doctor, in fact, I’m only 13 (today is my b-day!) but I think that you should get it checked right away. Have you had any history with problems with your sight? Do you wear glasses? When did you start seeing these symptoms? At school or work, is this virus or “flu” going around? Do you know anyone else with these same symptoms?
Back to the illusion. I think this is because the lines are parallel, but not at the same height. My theory is that they are in fact congruent. Also, the red lines are next to a different amount of tiles.
I’m not a doctor, but I have a very similar symptom when I get migraines. Moving my eyes in the sockets to look around is actually very painful. My doctor prescribed some prescription medication that works wonders, no idea what it is specifically though.
i would recomend….see a doctor dude haha nice image by the way hope you get better dude god bless…
My diagnosis is that you have been looking at too many optical illusions :)
OMG SO OLD!
It’s not so mind boggling. It’s only the depth perception that we see. If from your point of view something in the distance is the same height as something in the foreground. It means that the one in the distance is larger. It’s common sense.
FIRST!!! THE BIG BRAIN AM WINNING I’M THE GREETEST, I WILL NOW LEAVE EARTH FOR NO RAISIN!!!
Very nice one. I can’t get it right in my mind either.
And I sure hope you get well soon :-)
Like my Doctor always says ‘Well, dont do it then’.
Other than that, either sinus trouble, eye strain, brain tumor, or the black death.
Striking example of that old illusion.
very nice optical illusion today… all the better for being based on a real photo.
(is it a migraine?)
Insane, awesome and I’m the first to say it, also the first commenter!!!
first! Very Good Illusion, its awesome
Coooool
wow! first comment!! the illusion is pretty awesome!!!
Can’t believe the second line near the poster IS’NT Longer… I’ve seen lots like this but this is the most impressive
! ( 1st Post!)
The second line is longer, as it goes from the ceiling to the red tiles, but the other just spreads for one tile. Put it in Paint and then draw lines…You’ll see!
sorry about your cold, its son simple and so “illusion”
Is this Baker Street station on the London Underground?
Hi, I had the exact same headache last week and I agree it is the weirdest feeling. I was speaking to one of my lecturers who has researched migraines and he said that sort of headache is because blood isn’t being circulated through the brain properly. He also said if you also have high blood pressure you are at a higher risk of a stroke. So get it checked out!!!
Btw love the site! Keep up the fantastic work!
Go right up close to the screen that can help convince you and fog your eyes if needss be.
go see a real doctor my dear !
love your site :) ++
Take 2 of these and call me in the morning…

The illusion here has nothing to do with the red lines. The illusion is of a London subway (underground) station that appears to the untrained eye to not be littered knee deep in crap.
Yea I get that way ALOT when I’m sick, my doctor said it’s because of sinus pressure and to take a decongestant for the sinuses, it usually helps! feel better!
checked with photoshop and theyre really exactly the same, neat illusion, bravo!
also, i had the same flu and headache you’re having now… if you’d like to know mine went away with some hours of rest and juice.
What’s a headache?
