21 mind-blowing optical illusions(20 Pics)

1. The reason we are perceiving one color as two different colors is because of the other colors surrounding the stripes. Each of your eyes has six to seven million cones, which are concentrated in a central yellow spot known as the macula. These cones measure color in different wavelengths, where some of which overlap. Our brain then compares by measuring the differences in wavelengths between the colors. When certain colors are combined, the brain can’t process the data from the cones correctly and we get confused.

2. Cross your eyes, and a figure you’ll most likely recognize will appear.

3. Do the shapes look like they are floating? Try concentrating on a single one.

4. Do you see someone looking directly at you, or the side profile of someone?

5. Look at the left end of the picture, how many prongs do you see? Now look at the right.

6. Scan the picture from left to right. Anything happening with the dots?

7. The lines in this picture are clearly curved right? Wrong. They are actually all straight lines.

8. The top yellow line is clearly bigger than the bottom one right? Wrong. They are both the same size.

9. Focus on one of the pillars. Now focus on the empty space. What do you see?

10. Rabbit or duck?

11. How many legs does this elephant have?

12. I don’t care what anyone says, those gears are definitely moving!

13. These two squares are the same color. Don’t believe me? Put your finger over the center line.

14. You should be seeing gray squares at the intersection of the white lines.

15. These may look like a whole bunch of lines going in different directions. It is actually nine parallel lines running diagonally through the pictures.
