Optical illusion
The optical illusion leads to perceiving reality in a distorted way through sight. This distortion can be caused by physiological reasons (through excessive stimulation in the eyes or in the brain) or cognitive (depending on the way we perceive the world).
Among the most significant and famous optical illusions we would have to highlight, for example, the mirages. These are produced as a consequence of the perception of objects that we see far away and that, when reflected in a smooth surface, give rise to a liquid surface that does not really exist. The clearest example of mirage is the one that takes place in the deserts where the circumstances to which the individual is subjected and the characteristics of the place cause him to see things that do not really exist.
He hologram is another important type of optical illusion. We can say that this is the result of a photographic technique that allows the development of three-dimensional images. However, we cannot forget other illusions of this type, such as the irradiationthe grid illusion or the stereogram.

mentalism and magic
The mental illusion, also called mentalism, is, for its part, that science or art that makes the person who develops it use suggestion, mental agility or stage magic to be able to undertake mental control, psychokinesis, clairvoyance or precognition. We can also establish that that is a branch within the known as illusionism.
It is known as illusionism (either Magicin colloquial language) to the scenic art that consists of using various means to create the illusion that something impossible is happening from the logical point of view: “Last night I saw on television an illusionist who cut a girl in half”.
Many are the characters that throughout history have become a benchmark in illusionism. However, among all of them, French acquires special relevance. Jean Eugène Robert-Houdin, who has been described as the father of modern magic. Among the tricks that he carried out throughout his career and that later became generalized, the one in which a person from the public shot him and he not only was not injured but appeared with the bullet between his teeth stands out.

The illusion according to psychology
For the psychologythe illusion is a hope that has no foundation. In a symbolic sense, an illusion can be said to be a mirage (something that seems real but isn’t): “I had the illusion of solving things with her but I realized that it is impossible”, “I thought I could win the race, although it was just an illusion”.
