Optical Illusions: How The Brain Tricks Vision
Optical illusions are tricks that show how our brains sometimes misunderstand what our eyes see.
Simple drawings can look 3D, still pictures can appear to move, and colors can be misinterpreted.
One example is the Pac-Man illusion, which tricks your brain into seeing a green dot that isn't there.
Another is the dress illusion, where the color of a dress is seen differently based on lighting.
These illusions happen because our brains quickly try to make sense of visual information and can sometimes make mistakes.
Optical illusions demonstrate a disconnect between what we see and what our brain interprets.
The Pac-Man illusion creates the illusion of a dancing green dot using the phi phenomenon.
The color of 'the dress' illusion is based on how our brains adjust colors based on lighting.
The scintillating starburst illusion creates bright rays of light that don't actually exist.
Various illusions, like the Asahi and cube color illusions, can trick the eye.
