Questions we often get asked: How do optical illusions work?

Optical Illusions can use combinations of colour, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain which uses its memory to help us correctly interpret what we are seeing. However, sometimes the brain can be ‘tricked’, creating a perception that in reality, does not match the true image.

Perception refers to the interpretation of what we take in through our eyes. Optical illusions occur because our brain is trying to interpret what we see and make sense of the world around us. Optical illusions simply trick our brains into seeing things which may or may not be real.
There are many different types of optical illusion including After-image, Figure ground, Impossible Objects and Hering Illusion.
