Illusions teach us all about our visual perceptions and its limitations. Colour, light and patterns are used to create images that can be deceptive or misleading to our brains. Information gathered by our eyes is processed by the brain, 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. Our illusion posts and products area fun way to explore your visual perception.
