What is optical illusion?
An optical illusion is characterized by visually perceived images that, at least in common sense terms, are deceptive or misleading.
The information gathered by the eye is processed by the brain to give a percept that does not tally with a physical measurement of the stimulus source.
There are two main types of illusion:
Physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type - brightness, tilt, color, movement.
Cognitive illusions where the eye and brain make unconscious inferences.
Optical illusion occur for two basic reason-
1. The brain often relies on past experiences to make assumption about what you being seen.
2. The functioning of the eye-brain system can be disturbed and the eye is fool or tricked.
