This article is about visual perception. See
Optical Illusion (Album) for information about the Time Requiem album. An optical illusion is always characterized by
visually perceived images that, at least in common sense terms, are deceptive or misleading. Therefore, the information gathered by the eye is processed by the brain to give, on the face of it, a
percept that does not tally with a physical measurement of the stimulus source. A conventional assumption is that there are physiological illusions that occur naturally and cognitive illusions that can be demonstrated by specific visual tricks that say something more basic about how human perceptual systems work. They trick your eye to make it seem like there is no illusion sometimes.
