What Is an Optical Illusion?
Optical illusions are fascinating visual tricks that confuse your brain. They make you see something that isn’t really there, or interpret a picture in a different way than reality. Your brain tries to fill in gaps, and that’s exactly why illusions feel so surprising.
One well-known example is the rubber hand illusion, where your brain can be fooled into believing a fake hand is part of your own body. Optical illusions like this show how powerful—and sometimes easily tricked—our minds can be.
