1. Optical Illusions

2. Why Does Our Mind See Illusions?

3. The Human brain put images together because it has learned to expect things; sometimes the data might get a little confused.
We may see an illusion because we know what we are expected to see, even though part of a picture or design may not be completely there. The basis of this is in how we perceive things.

4. That almost explains everything right there
That almost explains everything right there. If our brain and eyes did not function like they do, we would not see illusions like we do.

5. A computer monitor is one big optical illusion
A computer monitor is one big optical illusion. Sometime, when you have a chance, look at a computer screen very closely for a minute or two. You will notice that your computer screen is made up of tiny red, green, and blue dots.
The illusion here is that you see more than just red, green, and blue dots; you see thousands of different colors. Our brains put the red, green, and blue dots together to make the colors!

6. Optical illusions just trick you into seeing something else
Optical illusions just trick you into seeing something else. They are an error in our perception of the illusion.

16. It's a spiral, right?
No, these are a bunch of independent circles

17. Keep staring at the black dot
Keep staring at the black dot. After a while the gray haze around it will appear to shrink.

18. Stare at the black lightbulb for at least 30 seconds
Stare at the black lightbulb for at least 30 seconds. Then immediately stare at a white area on the screen or at a sheet of paper. You should see a glowing light bulb!

19. What does the sign say? Are you sure?

20. Do you see the face? Or an Eskimo?

21. Do you see an old man's face or two lovers kissing?

22. You probably read the word ME in brown, but
You probably read the word ME in brown, but when you look through ME you will see YOU!

23. The "illusion" is that this is just a picture of coffee beans; but it is not. Can you find a man's face among the beans? Some say that if you find the man in 3 seconds or less, the right half of your brain may be more well developed than most.
PS: This is not a trick. A man's face is really hidden among the beans.

24. The following pictures are NOT animated.

28. How many human faces can you find in this picture?

29. Two elderly faces, or a larger scene?

30. Faces or places?

33. Where does the puzzle begin and end?
