here are a bunch of eye illuisions.







Notice how the placement of blocks in this eye illusion not only makes an interesting pattern, but it makes the center of the checkboard appear to bulge out. Of course, all the lines are perfectly straight, if you move your head close to your screen, you will see that this is true.


At first when I saw this illusion, I was thinking... what the heck is this? That's a pretty funky illusion, and I'm not sure what it's supposed to be. Well, at first, you'll notcice that the vertical lines are pretty messed up. But then as you look at it longer, the thicker black lines will start to look like walls in a room, and the white square will appear to be very far away. Before this optical illusion gives you a headache, better click on, my friend!



When you keep looking at the image, it seems to be moving before your eyes. That's because the lens of you eye is not perfectly round. You can't see all of the image sharp, and your eye is constantly making small movements. When you follow the outer rim, you will see that it is impossible. There is also an illusion of depth to this image, giving it a 3-d feel.



Are you sure you really see it disappear?

If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour - pink.
However if you stare at the black “+” in the center, the moving dot turns to green.

Now, concentrate on the black “+” in the center of the picture.
After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear.
Proof enough that we don't always see what we think we see...

Keep staring at the dot and then the gray circles around it will start to disappear.

cool illusions rosy those kinda made my eyes hurt but i like the one with the dots. it was kinda cool.
