People's minds are confused when they look at an illusion. Why does our brain play with our ability to see and think? Illusion is defined as something that confuses our mind. Illusion is something that is a distortion of all the senses, revealing our brain's process of how it organizes itself and how it interprets sensory stimulation. Sensory stimulation is a term that is described as an intervention designed to stimulate one or more senses. Illusions distort reality, they are generally shared by most people. The illusion occurs with all our human senses, a very understandable illusion. The name of this illusion is visual illusion, this illusion is intended to dominate all other senses. The optical illusion known as visual illusion is mainly characterized by many perceived images that have different goals from reality. The information gathered states that a human eye will be processed that will provide a perception that corresponds to a physical measurement of the stimulus sources. There are three basic and main types of illusions that confuse people's minds: first is the visual illusion (also known as optical illusion) which creates an image in the brain that is different from the objects that develop it, then is the illusion physiological which has an illusion effect on your eyes and brain when a specific type is used such as brightness, tilt, color, motion, last are cognitive illusions where an eye and brain make very unconscious inferences. The physiological illusion is the successive images that follow the bright light, also adapting the stimuli for an excessively long alternating pattern, are assumed to have an effect on the eyes and brain of a human being. It also has excessive stimulation such as brightness, tilt,...... half of the paper, and fiction, illusions.• "Ambiguous illusions are images or objects that elicit a perceptual "switch" between the alternative interpretations: the Necker cube is a well-known example; another example is the Rubin vase.• Distorting or geometric-optical illusions are characterized by distortions of size, length, position or curvature. A striking example is the Café wall illusion they are the famous Müller-Lyer illusion and the Ponzo illusion • Paradoxical illusions are generated by paradoxical or impossible objects, such as the Penrose triangle or the impossible staircase seen, for example, in MC's Ascending and Descending and The Waterfall. Escher is an illusion dependent on a cognitive misconception that adjacent edges must join • Feigns occur when a figure is perceived even though it is not in the stimulus.” (Brandon Trans, 2006)
