About

An optical illusion involves "tricking" your vision by taking advantage of how the eyes and brain work together to interpret the visual stimuli in our environment. Such illusions can be helpful for learning more about how the brain works.

The three main types of optical illusions are literal illusions, physiological illusions, and cognitive illusions.

Literal illusions are those where two images are combined so that more than one image may be perceived.
Physiological illusions overstimulate the brain with light, shapes, and colors.
Cognitive illusions are like logical paradoxes that present inherently contradictory information.

This digital collection contains images of some common illusions and explanations of how they work. Most of the pages are intended for general audiences. Academic papers are included for further investigation.
