Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Ouchi Optical Illusion

The Ouchi illusion, illustrated below, is an illusion named after its inventor, Japanese artist Hajime Ouchi. Notice how the circular disk seems to float above the checkered background as your eyes scan the image. This effect can be heightened by grabbing the scroll bar and sliding it up and down while viewing the image.

I am enjoying your optical illusion posts. Have you explored any concepts relating to how psychological factors, innate wiring, and other factors affect our visual perception? This can be quite important in many occupations and situations (Radiology) where there are many optical illusions that affect how we interpret an image.
