How do illusions affect everyday life?
Optical illusions are cleverly designed to distort reality, but did you know that the same distortions occur frequently in everyday life?

Is Illusion a disorder?
Disorders. Some illusions occur as a result of an illness or a disorder. While these types of illusions are not shared with everyone, they are typical of each condition. For example, migraine sufferers often report fortification illusions.
