Question

How many types of illusions are there

Answer 1

An optical illusion is characterized by visually perceived images that are deceptive or misleading. The information gathered by the eye is processed by the brain to give a perception that does not tally with a physical measurement of the stimulus source. There are three main types of illusion – literal optical illusions that create images that are different from the objects that make them, physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type – brightness, tilt, color, movement, and cognitive illusions where the eye and brain make unconscious inferences.
1. Literal Illusion

2. Physiological Illusion

3. Cognitive Illusion
