illusions to increase their reputations in paintings or sketches. So have architects. This essay discusses what is involved in optical illusions, how and why they occur. The types of
optical illusions is discussed as is the research about them. Optical Illusions Neuroscientists have studied optical/visual illusions for at least the last three decades. What they have learned only
confirms things that artists, illusionists, and military strategists have known through trial and error practices. The human eye, as wonderful as it is, sees with very low resolutions and has
limited scope (Kucera, 2011). The brain processes the images two-dimensionally and translates that into the vivid three-dimensional world we experience. However, the process includes shortcuts the brain has
learned and this is how the brain is deceived. It is how artists and magician trick our minds (Kucera, 2011). There are three primary types of
optical illusions: literal optical illusion, physiological illusions, and cognitive illusions (Hughes, 2011). One hypothesis is that optical illusions occur because the neural circuitry in the human visual system evolves
through neural learning to a system that can efficiently make interpretations of the three-dimensional scenes that are already stored in our brains. When those scenes do not fit what is
stored and an unusual situation occurs, an optical illusion happens. There are four specific types of optical illusions. Ambiguous illusions are objects or pictures that lead to a perceptual switch
between interpretations of the scene. Distorting illusions distort the picture or object in length, size, curvature, or position (Hughes, 2011). Paradox illusions are those that are impossible or paradoxical.
A good example is the very famous staircase illusion. It is impossible. Fictional illusions are described as perception of objects that are not there more often referred to as hallucinations
