Optical illusions

Optical illusions are illusions that occur in the sense of sight and that lead to perceive reality in several different ways. They can be physiological, when they are associated with the effects of excessive stimulation in the eyes or the brain (brightness, color, movement) or cognitive, when our knowledge of the world intervenes to create the illusion. Cognitive illusions are usually subdivided into illusions of distortion, illusions of ambiguity, paradoxical illusions and fictional illusions (hallucinations), where images are not clearly perceived by the human eye, as our brain is not capable of assimilating two images at the same time. . In short, the human brain is only capable of concentrating on one object, so when two shapes are presented in a single image, confusion occurs and the brain becomes disordered, which leads to perceiving a different vision of what has been seen. .

Optical illusions are not subject to the will of the individual and may vary from one person to another, depending on factors such as campimetry, visual acuity, color blindness, astigmatism and others. It is useful to understand these phenomena in order to understand what limitations the human sense of sight has and its possibility of distortion, in terms of the shape, color, dimension and perspective of what is observed. Optical illusions are produced physiologically when the right and left hemispheres are connected since, thanks to this phenomenon, we have the ability to perceive.

Below we show you a series of optical illusions for enjoyment and entertainment, or for use for educational purposes.
