Optical illusions usually consist of visually perceived images that differ from objective reality. When viewing illusions your brain falls victim to the creator’s intentions. There are three basic categories that illusions fall into:
- Literal– these optical illusions create images that are different from the objects that make them.
- Physiological– illusions that appoint effects on your eyes/brain of excessive stimulation such as size, position, tilt, brightness, color, and movement.
- Cognitive– illusions that put out unconscious inferences.

Found in virtually every psychology textbook in the world, the two monsters in this optical illusion are in fact the same size. Your brain automatically adjusts images that it perceives to be distant in order to compensate for the fact that they are larger than they seem.
