How Does Optical illusions show how we see | Beau Lotto Work?

Optical illusions are like puzzles that trick your eyes and brain into seeing things that aren’t really there, just like when you look at a rainbow on a rainy day and think it’s magic, but it’s actually science.

Imagine you're playing with blocks. You have two blocks that are the same size, but one is on a white background and the other is on a black background. When you look at them, the block on the white background seems smaller than the one on the black background, even though they’re exactly the same! That's because your brain uses clues from around the block to guess its size.

Beau Lotto studies how our brains interpret what we see. He shows that our brains are like detectives, they use all sorts of hints and tricks to figure out what’s going on in the world. Sometimes, those detective skills make us believe things aren’t really there, just like when you look at a picture and it seems to move even though it's still.

So optical illusions are like fun games that your brain plays with your eyes, and Beau Lotto helps us understand why we see what we do!
