hypnotic eye illusion

test your eye ability by viewing and shaking pictures

Optical illusion is an illusion that occurs because of the mistake of catching the human eye. There is a conventional assumption that there is an illusion that is physiological and there is a cognitive illusion. Optical illusion has amazed humans throughout history. Greek architects use optical illusions to make sure that the poles look straight (they make them with swabs) and we are all impressed with the mental twist involved in the case of a young woman / girl's face. New research published in the open access journal BioMed Central, BMC Neuroscience shows a more serious use of these illusions in understanding how the brain assesses relative size. Researchers from University College London use two famous illusions: the Ebbinghaus illusion, where an object surrounded by small circles looks larger than the same thing when surrounded by large circles, and the illusion of Ponzo, where an object in a centered line (such as rail or tunnel) look larger than the same object near the observer. Physiological Illusions Physiological illusions, such as those that occur in afterimages or images that occur after seeing a very bright light or seeing certain patterns of images for a long time. This is thought to be the effect that occurs on the eyes or brain after getting certain excessive stimuli. Cognitive Illusion Cognitive illusion is assumed to occur because of the thought of something outside. In general, cognitive illusion is divided into an ambiguous illusion, illusion of distortion, paradoxical illusion and fictional illusion. In an ambiguous illusion, images or objects can be interpreted differently. Examples are: Necker's cube and Rubin vase. In the illusion of distortion, there is a distortion of the size, length or nature of the curve (straight curve). Examples are: the illusion of cafe walls and the illusion of Mueller - Lyer. The paradoxical illusion is caused because objects are paradoxical or impossible.
