Here's an optical illusion that will mess with your brain. There's a picture going viral that looks like a bunch of random color blobs. But if you stare at it for a little while . . . it DISAPPEARS.
It's because of something called the Troxler Effect. When you stare at something long enough, it causes your eyes to adjust and makes some parts fade out of your vision. And the way this picture is designed, it makes the colors fade.
