Growing up, optical illusions were always entertaining to me. You can't believe everything you see! Our brain applies expectations of how lines have to flow on pictures we see. Perception is manipulated by our brain. Only little of what our eyes perceive is passed to the visual cortex. Therefore, your brain creates a bigger amount of what you see from memory and expectation.
Optical illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains. It is a way of tricking the brain to see something that may not be there. A computer monitor is also an optical illusion. The screen is made up of tiny red, green, and blue dots. Believe it or not, some illusions can actually be dangerous. Our sense of equilibrium or
balance is located in the inner ear but it works closely with our visual
world. Some experiments show that some mammals are fooled by illusions in much the same way as people are. Illusions can be fun for everyone
