Mike just sent us this optical illusion. The question is – Are the purple lines straight or bent? I know the answer, from my experience messing with this kind of illusions every day. But it’s up to you to solve this one.

    STRAIGHT!! DuH! everyone knows these ones…

  • Mike

    No, they’re bent! I bent them myself before I snapped this picture. Trust me!

    • Ryanna

      the lines are straight

  • christina


  • HAnkkepoo

    They look bent but they are straight!!!

  • Graeme

    They are sraight, just like me.

  • Rayne

    They are straight. I saved the picture and on paint shop pro I put a straight black line in the middle of the purple ones, and it fit perfectly. Nice try though. :)

  • chetu

    they look straight

  • Baycan

    Well if youll look at the black spot in the middle for a short time , and then stair at a white piece of space , youll see perfectly that its straight and blue with black lines .

  • yemoja

    they are straight

  • BurninRubber

    I AGGREE with uh… MMM. They are straight. They look bent because…. I have 2 theories.
    1. The affect of the black circle in the middle and lines
    2. The lines are 3D, Giving off the ‘bulging’ affect.

  • alana

    i agree 100% with BurninRubber and MMM Straight and those stupid lines cause a “bulge”

  • B34ST

    This is just like the space theory where a massive object distorts time! You can see a star behind the star/planet/black hole because the massive object bends your line of sight around the object! just like the black spot makes the lines do!

  • Garrow

    They are straight. The circle in the middle is also in the center of a thin straight black line which causes a bulging appearence on the larger purple lines. The background is yellow, which on the color scale is the opposite of purple, causing distortion in the smaller color. If you also look closely, the purple line has small distorted dots. The purple lines are STRAIGHT!!!!

  • Q_TPIE

    weird comments, but the lines are definatly strait. if you hold a piece of paper up to the purple lines you will see that they are perfectly strait.

  • A random person

    Very clever…. but they’re straight…..

  • XxXCarlyXxX

    there straight, put a piece of paper underneath the line n you’ll se its perfectly straight

  • Manda

    MIR4CL3 its called the space button
    seriously its annoying when ppl do that
    its the long one on the bottom just in case you didn’t know and yes they are straight

    5mm out off square butt straight

  • Prashant

    Well, its a gud one, & I know the reverse sort of effect, which makes u think the lines have bulged in together, I’ll post it.

  • hiya

    Stare at the black dot for about 5 seconds [counting like this: 1001 1002 1003 etc.] and then the purple lines start looking straight but don’t take your eyes off the black dots. My servants told me this. [I'm a princess living in a palace in India.]

  • Matt

    the lines are straight. to see it, look at them from either side of the screen. As if you were looking along a wall. the illusion is revealed. wasn’t this one in my elemenary school library?!? :)

    my eyes hurt!!

    course there straight other wise it wouldn’t be an illusion if they were bent

  • Anonymous

    The line is straight.
    There is a reason why:
    The pixels in the picture are very big as you can see on the diagonal lines. The Purple lines don’t have any pixels out of place, so theyre straight.

    It looks bent sometimes to me, then straight.

    It is definitely mind-boggling, but they are strait.

  • Dolphin
