25 Incredible Optical Illusions

Things aren’t always the way they appear. Although our mind is constantly trying to make sense of the world around us it can sometimes get a little out of control and make us start to see things…literally. While, some of the optical illusions on our list are relatively famous, others are a bit more obscure but all of them give us a glimpse into our amazingly complex minds. There is no magic involved, no strings attached, its all in your head. Here we go.

Rotating Rings

Rotating RingsIf you stare at the dot in the center and move your head away from the screen the rings will start to rotate. Now gradually get closer again…they change direction!

Hermann Grid

Hermann GridThis is a classic illusion named after Ludimar Hermann who discovered it in 1870. At every point where the white lines intersect our eyes perceive a gray, shadowy blob. If you look directly at one of the intersections though, the blob disappears.
23

Fading Image

Fading PictureStare at the image for about half a minute without moving your eyes and watch as it gradually disappears. This is a variation of Troxler’s effect which essentially says that if you fixate your eyes on a certain point, stimuli near that point will gradually fade.
22

Kanizsa Triangle

Kanizsa TriangleThe Kanizsa Triangle was named after the psychologist Gaetano Kanizsa who first described its effect. When you look at the image your brain creates contours (outlines) of a triangle although none exist. In reality it is an illusion created by the the wedges and the angles.
21

Blivet

BlivetThis is a rather famous illusion of an impossible object. It has two rectangular prongs at one end that morph into three cylindrical prongs at the other.

    So fucking dizzy..

    the spinning silhouette actually DOES change direction. if you watch it long enough, it “glitches” briefly before spinning in the opposing direction. spins longer clockwise than it does counter-clockwise.

    • Steve Adams

      Actually, it does not. Your mind makes you think that, I studied this in Psychology at university.

      The mind is a wonderful and ridiculous thing.

    • Akiero

      Steve is correct. You just need to force your mind to stop giving depth to the image and you can actually start to see her leg just wobbling back and forth. After you achieve this, you can make her spin whichever way you want for however long you want.

    • Teresa Breuer Page

      I agree 100% with Rebecca that the dancer actually changes direction, because you can tell if she is leading with her left arm and leg or her right arm and leg, and you can actually see the switch (maybe the illusion is in the fact that we can actually change her direction) but either way, she is literally moving in 1 direction or the other.

    • Frank Reese

      I fully accepted what Rebecca was saying until I actually pulled the gif apart. There’s no hoccus pocus, it’s a 25 frame (or around that amount) image all all 25 are seen ever lap. There’s no hidden trick.

      It’s your mind. You hear that? That’s your mind blowing.

    For the lady moving in a rotation either left or right clock wise or counter clock wise….if u want her to change…think about art work and how you would draw a picture…to make her switch…. start counting numbers and doing math

  4. The last one? No way!

    • d_ryan1122

      HAHA yup! its an ocular/brain relationship…Art and creativity is one side of the brain were as math and science is another.

  5. as to the spinning lady: Just blink your eyes rapidly and she will stop and spin in the other direction.

    • Tyler

      That worked! I see her clockwise most of the time, but when i started thinking about Starry Night, she went counterclockwise. Switched her back by doing derivatives in my head :D Ive never seen her go counterclockwise before now, thank you!

      • Phoebe

        !!!!!! That totally works! When I thought of my favorite song, she turned counter-clockwise and when I added simple numbers, she turned clockwise. SO COOL.

  6. John TheShark DeLeon

    this shit cray

  7. Robigus

    Per the spinning lady, nothing I try makes her spin counter clockwise. I tried blinking my eyes rapidly, sang songs in my head, sang songs outloud…started the math with simple addition, moved onto multiplication, shifted to square roots, then Fibonacci sequences….am artistically challenged so didn’t bother trying to figure out how to draw or paint anything.

  8. Danny

    For the spinning shadow, watch the REFLECTION of the foot briefly. It will help you switch direction almost at will once you understand what you’re doing.

  9. Amber

    I like your illusion collection, however, in the green and blue illusion the green and the blue ARE different, I did just check in Photoshop.

  10. 16 is wrong.

    The green shifts between R: 113 G: 255 B: 255 and R: 114 G: 255 B: 255 while
    the blue varies from R: 110 G: 255 B: 255 to R: 121 G: 255 B: 255.

    While the principle of the illusion is proven, the image shown in this instance does not have the blue and green as being precisely the same.

    • Absolutely correct.
      Close colors, but not exact

  11. ahh i keep seeing jesus every time i blink

  12. Vedette

    im getting dizzy by the minute.

    Silhouette – To change the direction, I’ve found that it helps to gesture with my hands. Plus, it makes me feel like a wizard. =3

  14. The “spinning silhouette” doesn’t move at all for me…actually, half of these didn’t work.

  15. i can get her to “spin” in the opposite direction if I stare at her knee very hard for a minute or so

  16. Jorja

    I finally got it! Every time I’ve seen that stupid dancing woman, I’ve only been able to see her going clockwise, but pretending you’re a wizard really helps! Thanks!
