OPTICAL ILLUSIONS The Art of Deception of Perception Essay

â€Å"Our senses can be trusted, but they can be easily fooled†(Aristotle 1) What is an optical illusion? For most of us, the term brings to mind images of a unique arrangement of vibrant contrasting colors, and geometric shapes that deceive the eye, and violates our expectations in a myriad of ways â€Å"about representation, about shape, about color, and so forth†(Sekel). Figure 1 is one common example of this definition. In this image the circles appear to be expanding when in fact the image is static. Another example of an optical illusion would be Claude Monet’s painting Rue Montorgueil in Paris, Festival of 30 June 1878(Figure 3), which illustrates a scene of a festive street, but most people do not†¦show more content†¦First light enters the eye and is refracted by the cornea through the pupil, which is â€Å"the circular opening in the centre of the iris†(Eye Anatomy 1).The light then travels through the lens - located right behind the iris- which completes refraction by â€Å"fine-focusing† the light onto the thin layer of tissue which lines the inside of the eye called the retina. In the retina light is converted into electrical impulses which are carried via optic nerves to the brain -as shown in Figure 3. The brain then interprets these impulses (Refractive Surgery 1). The visual information from the eyes initially enters the brain at an area of the cerebral cortex known as the primary visual cortex (V1) as shown in Figure 4, where there are groups of cells which â€Å"break down these stimuli and respond to them†( MIT Research- Brain Processing of Visual Information 2). The primary visual cortex is not the only area of the brain devoted to visual information. There are many cell clusters in various parts of the brain that â€Å"cooperate to process different components of visual information† including color, movement, shape, size, and many other components ( MIT Research- Brain Processing of Visual Information 2). Several case studies have suggested that â€Å"the brain divides a visual scene into sub-dimensions such as color, depth, movement and form and works on each aspect simultaneously†Show MoreRelatedExperience, Perceive And Interact With The Sites Through Our Senses And Body4205 Words   |  17 Pagespresenting haptic and optic as binaries, but as modes of perception that switch and synergise with one other to ‘restore a flow between the haptic and the optical’ (Marks, 2002: xiii).

Films also referred to as motion pictures, involves projecting a series of images into the screen to create an illusion of motion. It is one of the most popular forms of entertainment, enabling people to immerse in an imaginary world for a short period (Olaleye, 2007).
