AI Thread Summary
Optical illusions occur because the brain attempts to interpret images based on visual cues and context, leading to multiple valid interpretations. These illusions often present two distinct perspectives within the same image, such as the well-known example of the faces versus the vase. Many individuals may not recognize the alternative interpretation until it is pointed out, highlighting the brain's reliance on prior knowledge and assumptions when processing visual information.

Does anyone know why we experience optical illusions?

Because the brain does its best to figure out what's in an image. Illusions are images that purposefully have two valid, yet distinct interpretations (like the famous one with either the faces or the vase). Most people won't even notice the alternative interpretation until someone tells them it's there.
