How many faces can u see in this optical illusion? An optical illusion is characterized by visually percieved images that differ from objective reality. The information gathered by the eye is processed in the brain to give a picture that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images 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, and cognitive illusions where the eye and brain make unconscious inferences.
