Watch as your eyes see nothing…..


This is a great illusion.  Look at the animated gif below.  You should see a rotating blue grid (if it is still, click on it to open the image in another window).  Next, simply stare at the flashing green dot.  All being well, some or all of the yellow dots will vanish!

Did it work for you?

    Yes it’s awesome. The yellow dots vanish, then come back briefly, then are gone again, etc.
    But for some of us with red-green weak vision, the flashing dot is exactly the same color as the ones that vanish – my perception is that all four are “yellow”. Doesn’t matter, “Stare at the flashing dot in the center” works just as well.

  2. CaspaB says:

    Even weirder: after staring for a while I moved my gaze to the edge of the window, and it curled around slightly into an “S” shape.

    Brilliant! How does it work?

  4. CaspaB says:

    And if you put the mouse cursor near the green flashing dot and look at it, the yellow dots also disappear. If the cursor is near a yellow dot, it disappears last. What a versatile illusion. Thanks, Richard.

    CiaraMK, Our eyes detect changes in light intensity, and if the scene does not change, our eyes jiggle a bit to stimulate the light sensitive cells (look up saccadic). The rotating background and flashing green dot supply the movement, so our eyes don’t need to jiggle. Without movement of the yellow dots, they seem to fade.

    Great illusion, and CaspaB thanks for the explanation.

    Five years ago and it is written in Spanish, we wrote about this and others optical illusions

    In this illusion it is very interesting with several people, one looking always at one point and others to others points and then… saying that they see different things…

    Nice one! It also worked for me.

    How does it work? This article from the BBC website may explain how:

    What do you think?

      We’re sorry but this site is not accessible from the UK as it is part of our international service and is not funded by the licence fee. It is run commercially by BBC Worldwide, a wholly-owned subsidiary of the BBC, the profits made from it go back to BBC programme-makers to help fund great new BBC programmes.

      What crap !

    Thanks for another fascinating one, Richard and, yep, one particular yellow dot occasionally disappeared and reappeared; and, interestingly enough, after a while, there seemed to be a subliminal broad black grid within the background, formed by the patterns between the grid itself: it’s intriguing, how the mind seems to form patterns wherever it can 🙂

    Very strong effect
    Where do those spots go?

    The yellow dots disappear without the animation. I say it has nothing to do with movement.

    Oops, the should say “The beginning of February. I signed up on the 3rd.”
