Optical illusions are images that are perceived visually different from what they are reality. They force the eye to gather information wrongly which is then processed in the brain which results in a perception that differs from the reality. These are just some of hundreds or thousands of illusions found all over the internet  Stare at the red dot on the girl's nose for 30 seconds. Then look at the blank white space and blink really quickly a few times. You will be amazed to see a colorful girl. The rods and cones in your eyes lose sensitivity from over-stimulation, and for a short period afterwards, colors are interpreted as their paired primary color. This is an example of after-image illusion  As you stare into the black dot in the middle, the brain adjusts for its surroundings and erases all the fluff around the edges. This is called Troxler's effect, and shows what amazing things extreme focus can do!  This is a bistable illusion where you can see movement both clockwise and counterclockwise.  Surface color of both A and B parts is identical. Just use a finger to cover the place where both parts meet and you'll see.  You probably see angry face on the left and calm face on the right. Now step away from your computer screen. You should see the two faces swap over! It proves that we may not be seeing what's actually there, all the time.  Keep an eye on one of the yellow dots and the other yellow dots vanish.  The circling green dot you see when you focus on the middle cross actually exists only in your mind.  This Image is actually a still image. And this -  And this -  Which of these do you find most amusing? |
