Ever wonder how your eyes play tricks on you?
Optical illusions are images or pictures that you perceive differently than they really are.
Visual illusions occur due to properties of the visual areas of the brain as they receive and process information.
In other words, your perception of an illusion has more to do with how your brain works and less to do with the optics of your eye.
Host of The Wizard of Eyes, Dr. Robert Abel, explains this visual phenomena and why optical illusions simply trick your brain into seeing things which may or may not be real.
