Optical Illusion

Optical Illusions: When black and white appear to have color or straight lines curve or when pictures move or if you just can’t tell what it is. They’re strange and hard to wrap your head around, but to be real, these illusions are just your brain taking a couple of shortcuts. Because it’s really difficult for your brain to focus on everything, it will cut through what it perceives to help you focus. It’s like when you play a video game and the game lags. The game is performing so many commands per frame, the game is slowing down. Your brain has about a process lag of about a tenth of a second, so it needs to take short cuts. According to, “This trait helped early humans survive encounters with fast predators or at the very least avoid running into obstacles like trees.“ When your brain can’t work around it like you would expect, the images your brain sees blur together. This will create an optical illusion.
