strange this happening Illusions means decieve. But in science it means wrong perception of our brain. Some illusions are induced by drugs and some are natural. Below are natural illuions. Orange Square Think you see a faint orange square? There is no square there! Cover up the circles, and you'll see that the area between the circles is white. Only parts of the circles are orange 
You understand what you look at because your brain interprets every visual aspect of an image�the color, the shape, the size, etc. Your brain understands color based on what surrounds that color. So exactly the same colors can be interpreted differently depending on what is around them. That's why some of the white on this page looks orange. The orange surrounds some of the white, and your brain "spreads" the color over the white Drifts Stare at the yellow parts of this page. Even though you're not looking at the illustration directly, you can still see it, right? (You're using your peripheral vision.) The center should look as if it's drifting down; the outer sections should appear to drift up. 
Experts think slight color changes can trick the brain into thinking that an image is moving. This illusion�discovered by vision scientist Akiyoshi Kitaoka�is called "perceptual drift" because the brain perceives parts of the image to be drifting. Black Spots Can you count black spots in this picture???? 
No because there is no black spot in this picture, when ever you try to look at black spot it will turn into white. Actually there is no black spot in it and all those shown are illusions. Invisble Look at black + and close your right eye with one hand. Your eye must be infront of + then come near to then start getting back from sceen. There will come a place where you cannot see this red X Same thing will happen if you close your left eye and look at red X and start getting back from computer screen, there would be a place where black + will become invisible 
You can also try this one
Fact about it is that you have a blind spot in your eyes where nothing is visible, when you do as stated above, X become invisible when its image falls on blind spot. |
