Understanding Perception: Optical Illusions and Your Eye


Your brain and your eyes work together to see and know the world around you. For example, your eyes see your friend's face, but it's your brain that remembers who they are. It's easy to think that you see things exactly as they are, but it's just as easy for your eyes and brain to be tricked by what they see. The direction you look at something, the way part of a picture is drawn, and even the colors you see can all change the way something looks to you. They can also change the way an object looks to someone else. For instance, you might see a different color than your friend does, even if you're looking at the same object. Optical illusions and eye tricks are pictures, sculptures, and sometimes even words that are made to try to trick your brain into seeing something. Testing your eyes with optical illusions can be a lot of fun.
