The broad definition of an optical illusion is essentially any image perceived by your eyesight to be visually deceptive. For example, an optical illusion pertaining to color can be created when a bar of one color is surrounded by a box containing a gradation of color. The result of these two objects together cause us to perceive the bar within the box possesses a gradated color scheme as well, even though it is in actuality a single color.
An optical illusion occurs because the different cells and receptors of the eye perceive images and colors at different rates, which sometimes result in a false image being relayed to the brain. The brain receives information from receptors in the eye, but in actuality, the eye only perceives a certain quantity of visual information at any given time, while our brain continuously decodes, constructs and reconstructs visual information, giving us the illusion of continuous sight. The right combination of colors, shapes, spatial relations, and other stimuli viewed by the eyes and reported to the brain during the relays of information can achieve the effect of an optical illusion.
Ilusión óptica es cualquier ilusión del sentido de la vista, que nos lleva a percibir la realidad erróneamente. Éstas pueden ser de carácter psicológico asociados a los efectos de una estimulación excesiva en los ojos o el cerebro (brillo, color, movimiento, etc como el encandilamiento tras ver una luz potente) o cognitivo en las que interviene nuestro conocimiento del mundo (como el Jarrón Rubin en el que percibimos dos caras o un jarrón indistintamente). Las ilusiones cognitivas se dividen habitualmente en ilusiones de ambigüedad, ilusiones de distorsión, ilusiones paradójicas e ilusiones ficticias
Muchos artistas han aprovechado las ilusiones ópticas para dar a sus obras un aspecto mágico, de profundidad, de ambigüedad y contrastes.Las ilusiones ópticas fisiológicamente ocurren durante la conexión del hemisferio derecho y el izquierdo, gracias a esto tenemos la capacidad de percepción .
Optical Illusions are visually perceived objects and images that differ from reality.
