In complex words, Optical Illusions are characterised by visually perceived images that differ from
objective reality. The information gathered by the eye is processed in the brain, this gives you a different view on things, this different view is an optical illusion.
There are two main types: literal optical illusions that create pictures
that are different from the objects that make them, physiological ones that are
the effects on the eyes and brain of excessive stimulation of a specific type.
The first illusions can be based on an individual's ability to see in 3
dimensions from a 2 dimensional picture.
Just as it perceives colour and brightness constancies, the brain has the
ability to understand familiar objects as having a consistent shape or size. :)
