What's an Optical Illusion?
An optical illusion is "a visually perceived image that is deceptive or misleading." - American Heritage Dictionary, Second College Edition, p. 873
An illusion refers to "an erroneous perception of reality." - The American Heritage Dictionary, Second College Edtion, p. 642
An illusion is a false perception of reality; it can deal with mental or sensory processes. An optical illusion refers to a false perception of the eyes, i.e., seeing something that is not really present. Mental & sensor illusions are not uncommon in life & reveal our imperfect ability to understand reality. For instance, the ear can easily mishear a statement, especially in noisy places or when the listener is just 10 or 15 feet away from the speaker; & the eye can easily mistake a shadow for an actual object in poor lighting conditions or during moments of trauma.
