Optical Illusion an experience of seeming to see something which does not exist or is other than it appears.The information gathered by the eye is processed in the brain to give a perception that does not tally with a physical measurement of the stimulus source.Optical Illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains.


Throughout history, curious minds have questioned why our eyes are so easily fooled by these simple drawings. Illusions, we have found, can reveal everything from how we process time and space to our experience of consciousness.


This impressive illusion was created by Edward H. Adelson from the Massachusetts Institute of Technology. In it, the two squares marked with “A” and “B” appear to be two different shades of gray. In reality, they are actually identical in color.Yet, if you still trust your eyes more than those words, there are a few simple tests and scientific principles that will help you realize that your eyes are lying to you.


This optical illusion, known as the checker shadow illusion work because of the way the brain understands contrast and shadows. The human brain uses relative color and shading to determine the color of objects in an image (and in the real world).

In the above checker shadow illusion, Although our eye can see two identical shades of gray, our brain reasons that if the square in the shadow reflects the same amount of light as the square outside of the shadow, then it must be a much lighter shade of gray. In effect, our brain alters our perception of the image so that we see the colors as they would likely appear in the real world.

Square A appears to still be darker than square B. But it’s not

To test for yourself, pull up Photoshop or another photo editing software that has the capability to pull colors from an image. You will find that both squares have the same exact color profile.
