Free Optical Illusions

Check out our free optical illusions, and find out whether your eyes are deceiving you with the best visual illusions online. An optical illusion occurs when our visual system interprets an image or scene in a way that diverges from the actual physical properties of the objects involved. These illusions can lead us to see things that aren’t truly there or perceive familiar shapes and patterns in unexpected ways. This happens because our eyes and brain work together to interpret visual information. However, sometimes the brain relies on shortcuts or assumptions, leading to perceptual discrepancies. Clues related to depth, shading, lighting, and position help us make sense of our three-dimensional world.

In this optical illusion, can you see the beans move? If yes, that's impossible because it's a fixed picture. It's the way your brain is processing the image that gives the illusion of movement. Spooky!

At first glance the smaller squares inside this image appear to be a bit "wonky" but that's just an optical illusion. In fact, they're perfect squares!
