Another popular one – and quite unnerving if you’ve never seen it before! Here’s what I want you to do: close your left eye and just focus your right eye on the tiny static circle on the left of the screen. At some point the big circle will disappear as it crosses your ‘blind spot‘. If you can’t see this effect, it means you’re sitting too close/far from your monitor. Try sitting closer/further to the screen and repeat the test. So, have you managed to find your blind spot? Find Your Blind Spot!

    Why does my left eye have no blind spot?

  2. vurdlak says:

    Try openning the picture (you will get bigger picture, then it should work!)

  3. sebastian says:

    your left eye has a blind spot too. Just close your right eye and focus the moving circle with your left one. At one Point the cross will disappear. Et Voila: Your Blind Spot.

  4. Roach says:

    Umm, I put my finger where the blind spot is, but I can see it just fine. When blind my right eye, I see the circle too. On my left the cross dissapears but the finger stays. . .

  5. Farted says:

    WOW!! I am blind!!! I thought so…..JK…. this is awesome!

  6. WOW says:

    omg i have no blind spot and im not blind?:S:S:S y is this?

  7. fred says:

    i knew this one, but what’s amazing about this whole thing is that your eye let’s you ‘see’ the color which is around it, like it fills out the missing part with the right color. I tried looking at two white (/purple) dots on black (/green) backround. Where the other white (/purple) dot’s supposed to be, you just see black (/green). or better, you’re brain makes you think there’s also that color, since you can’t really see, what’s there ;)

  8. Neath says:

    This one doesn’t work so well for me….. My right eye is almost totaly blind. If I close my right eye the whle page is in my blind spot :P

  9. ~~*NIQUE*~~ says:


  10. Jee says:

    Doesn’t work for me…sorry

  11. jhop says:

    To make it work for your left eye you need to focus on a point to the right of the moving circle. This is because the blind spot (which is where the optical nerve connects to the eye) is on the left of your lef teye, and the right of your right eye (kindof)

    I recomend using a permenent marker to draw a cross on the screen….

  12. Hai says:

    aaagghhh! its gone!!!!

  13. bobo says:

    hahaha i like jhops idea

    my blind spot did show up

    but definatly if you cant see your blind spot use a PERMINENT marker

  14. y eye says:

    My left eye has a blind spot but not my right???

  15. biclops says:

    gah! more dissappearing dots, hold me

  16. A d J says:

    i guess i jus dont have a blind spot… oh well.

  17. eCass says:

    That’s very odd. My blind spot is like a strip to the right, but the spot reappears after it passes that strip of blind moving to the right. That’s very odd that your peripheral vision works in that area but you cant actually see the moving object.

  18. naofumi says:

    ya it doesn’t work for me.

  19. a Funny guy says:

    who thinks up this crap????

  20. Blind man says:

    that is freaaaaky!!!! I’m blind!!!

  21. y says:

    why does the ball dissapears and then reapear

  22. dude says:

    IF u go really close to the screen any eye will have a blind spot.

  23. circles to infinity says:

    its cool, i like it, i blame this for many car accidents and running into walls, not that i’ve ever been guilty of either, mind you. ;)

  24. Haywood Jablome says:

    I closed both eyes and didn’t see a damn thing.

  25. sam says:

    You got to move closer to the screen and focus on the cross.

    EVERYONE has a blind spot. The only time you wouldn’t have one is if you were a mutated alian

  26. Rayne says:

    It didn’t work for me with my right eye, so I tried it with my left. That didn’t work either. So I did what Vurdlak said and clicked the image. Instead of it being bigger, it was smaller so the cross looked like a dot! Oh well, nice try. :)

  27. Rayne says:

    I think it didn’t work for me because I have wierd eyes. Like when I was looking at the cross I could see my TV, which is waaaaaaaaaaay to my right and almost behined me (no it wasn’t the reflection of it on my screen). My eyes are lazy which is wierd, because for some reason I can see like an owl without turning my head!

  28. ishbu says:

    welllll either something is definitely wrong with my eyes, or the blind spot theory is wrong…
    i followed the instructions word for word, and even moved closer and further…
    but each time it was the cross that dissapeared…
    not the circle.
    and no i wasnt just focusing on the circle…
    i was definitely focused on the cross with my right eye and everything…
    but yeah…the cross disappeared.

  29. Rozz says:

    Every single Person has a blind Sopt unless you have no Optical Nerve in the back of your eye which would mean that the eye would be useless and wouldnt be able to see. So theres no point going – Ooo I musnt have a blind sopt – because you do! try moving back and forwards with your face! …idiots

  30. jhop says:

    The blind spot is the place where the optical nerve connects to the back of the eyeball. The back of the eyeball is covered with sensors (basically), but where the nerve connects, there are no sensors, so you cant see anything in that spot. I had a swollen optical nerve for a while, and my blind spot got big, about the size ofsomeones face!
    because you have two eyes, they sort of cover for each other, so you dont normally notice.

    You can also try focusing further to the left of the cross, your blind spot might be further out that the dot moves too.

  31. Joe T. says:

    Some have mentioned that their finger tips stay in sight when placed into their blind spot. i’ve seen another blind spot test in textbooks that demonstrates this. If you were to replace the circle with vertical bar that has a break in the middle:



    like that, when the break sits in your blind spot you’ll actually see:


    because your brain wants to fill in the “missing” information. This is why you can still “see” your fingertip. Your brain knows it is supposed to be there, so it fills it in. i did the same thing, and noticed that my fingertip was kinda blurry and a bit distorted. Perhaps i don’t know my own hands well enough.

  32. M 2 the H O says:

    vurdok wen u open it its tinsy

  33. M 2 the H O says:

    sabastian, the directions tell u to focus on the cross not the ball. focusing on both with my rite eye it dont dissapear,
    but only focousin on the ball with my left eye does the cross dissapear, O NO!!! WHAT AM I 2 DO?????

  34. M 2 the H O says:

    r both eyes supposed 2 have a blind spot i can onnly get it 2 work on my left

  35. Mal says:

    I diddnt know i am blind am blind

  36. SteakKnife04 says:

    it just mad my eye hurt

  37. some guy says:

    indeed it does work

  38. amazed says:

    that is so kool
    if u look on the other side your blind spot is in the opposite spot

  39. ;-) says:

    WOW!!!!!!!!! but it kinda makes me wonder wut else i mite be missing…

  40. hydrophobicsnails says:

    well i have 20/10 vision so that might be why i cant find my blind spot. i tried enlarging the picture i moved closer and further from the screen and i tried both eyes.

  41. no likey name says:

    i think it’s funny how some people are saying that they have no blind spot when every human eye has one.

  53. Anonymous says:

    your left eye does have a blind spot, to see it the cross would have to be on the right and the dot on the left while closing your right eye

  54. mcr rox says:

    i cant get my blind spot but its probably cause i have very bad eyesight in my right eye.

    uhh…hold ur hand on right eye and focus on right side,the cross will dissapear lol

  67. Alaar781 says:

    Perhaps it has something to do with my usually wearing glasses half the day and not wearing them now, but, when checking my right eye’s blind spot, I sometimes never see the black circle go away. As far as my left side, I can either not see or both see and not see the cross (seemingly with a very visible but ever-changing wind of white trying to hide part of it) at various states of focus.

  68. Nikki says:

    uh… i don’t think i have a blind spot…

  69. Matthew says:

    I found something interesting about this. if you place a mirror on the table under the image, you can still see the dot in the mirror but not in your blind spot.

  70. Anonymous says:

    if you concentrate on the cross with your left eye, you will not ind a blind spot because the left eye’s blindspot is on the far left side of it. The big circle is moving to the right, which is why it works on the right eye

  71. Anonymous says:

    Doesn’t work.

  72. JK says:

    Listen up: It has to work. you have to have a blind spot unless your anatomy is different from all other humans. If it doesn’t work, you’re doing it wrong.
    Like all others just said, you have to cover your left eye if you’re focusing on the cross and the moving circle should disappear at one point.
    If you’re focusing on the big circle, cover your right eye and the cross should disappear, or at least that’s how it was for me.

    what if only half of the dot dissappered? (i did indead try looking from different distances, but only time it dissapeared was the bottom half gone about five inches away from screen):?

      for the people it doesn’t work for – this doesn’t mean you don’t have a blind spot. everyone has one due to the anatomy of the human eye – the place where your optic nerve exits out of your retina (where it goes up to the brain), is your blind spot. the illusion isn’t working for me either, but I know I have a blind spot anyway :)

  110. Jazzy-J says:

    It’s no lie. Everyon has a blind spot in either eye. The backs of your eyes are covered in light-receptor cells, save for a small spot just off of the center. This is where the optic nerve connects to your eyes, and there are no light-receptors on that spot.

    • spook117 says:

      everyone has a blind spot
      if u didnt it would be because your optic nerve doesnt connect to your eye, which would make you blind

    To be honest it didn’t do anything for me either. I tried from far and near as well as both eyes, but it never disappeared to me. I think it may possibility blink lightening quick at the farthest point from the x… but I don’t know.

  149. Anon says:

    Welll…. 5 inches from the screen or 10ft from the screen.. I apparently have no ‘blind spot’ because I can see the moving dot the entire time with my left and right eye. Advanced Peripheral vision FTW.

    • KMR says:

      Just focus on the cross so you only see the dot in your peripheral vision. It is physically impossible to not have a blind spot because it is caused by your optic nerve.

  150. manuel says:

    you have to hold your face about 6 inches away from the screen.

  151. Iceman says:

    First of all you are to close your left eye.
    Close your left and eye and just focus your right eye on the tiny cross. I found my blind spot by accident one time. I asked my eye Dr about it and he said everyone has a blind spot, that I just happened to find mine.

  152. Adrian says:

    You guys are funny. EVERYONE has a blind spot. You just need to adjust your distance from the screen, 6″ to 8″ should do it.

    • Dr. J says:

      will work on the right side if you put your mouse pointer about an inch from where the large dot stops and reverses on the right side of the screen. Then look at the pointer with the left eye only.

    If you close your right eye the small circle disappears!

      You still have a blind spot in your good eye. Move about a foot away from the screen and try again. You didn’t try looking through the blind eye did you, just kidding.

  164. Dr. J says:

    The interesting thing about blind spots is that some people have larger ones then others and neurologicaly it can change with different stimulation.
