What is an optical illusion?

An illusion of optics comes from the perceptions or views that one has on an image or pattern. The mental load created from our eyes can make us see a whole bunch of shapes, colors, dimensions, or movements. Whether from a photo or an image (black and white or color), these optical effects are real puzzles! The brain is deceived for a few seconds. And our brain is done so: the mental photo, the information and the reading we do are analyzed but sometimes poorly decrypted.

Thus, even if your eye is well sharpened, you will feel like you don’t understand any illusions! Lama, dog, animals, colors, faces, lines… the list is long and Internet users love to have fun. Ready? Appointment available and test with our optical illusions! Eureka! You will enter the mysteries of science: watch out that these games do not become your new Lubie…

In addition, you can read articles on optical illusions to understand how the brain or eye works. Enjoy your brain with Youtube video channels dedicated to these science phenomena. You even create your own optical illusion!
