Optical Illusions

Optical Illusions can use color, 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, 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.

*There are three main types:
Literal optical illusions that create images that are different from the objects that make.
Physiological illusions that are the effects of excessive stimulation of a specific type (brightness, colour, size, position, tilt, movement),
Cognitive illusions, the result of unconscious inferences. Pathological visual illusions arise from a pathological exaggeration in physiological visual perception mechanisms causing the aforementioned types of illusions.

They also teach us about our visual perception, and its limitations. Emphasis here is on beauty, interactive experiments, and attempts at explanation of the visual mechanisms involved.

Personal Opinion: The optical illusions are awesome at the same time that confuses us.
