The Science Of Optical Illusions

Optical illusions are more than just a bit of fun. Scientist Beau Lotto is finding out what tricking the brain reveals about how our minds work. Sight, hearing, taste, touch, smell. We believe what our senses tell us but most of all we trust our eyes. But our brains are extraordinarily powerful organs.

Without us realizing it, they are instantly processing the information they receive to make sense of the world around us. And that has been crucial to our evolution.
