What is a vision deception?

The deception of vision or, as it is also called, optical illusions arises from the incorrect visual perception of the subject. Such errors arise from the incorrectness of the processes of perception of the visual image. Optical illusions were often the object of works by abstractionists in particular Salvador Dali, Maurice Escher and others.

Reasons for the deception of sight

There are two main reasons for which there is a deception of vision (optical illusion): psychological and physiological. That is why they are studied from the point of view of the psychological perception of the visual image and physiology of the eye and the view of the person as a whole.

Classification of optical illusions

- Color perception errors . These optical illusions are based on the effect of irradiation. Those. When the perception of the color of the object is influenced by the background on which it is depicted. Of course you will not notice a radical change in color, but the optical illusion of a different key is also impressive;

- errors in perception based on contrast;

- Curved optical illusions, as well as many others, are based on the difference in the background image, for which reason the brain perceives, for example, absolutely straight lines and parallel lines - curved and intersecting;

- deception of perception of depth;

- "flip-flops", as you understand from the name of the perception of these items depends on the direction of vision, for example, it may be a young girl or an old woman - depending on which side to look at;

- Ames's room. This optical illusion is named after the author Adelbert Ames. It has become classical and its effect is to change the objects that are inside this room. To be precise, the size of the object varies depending on its location in the room;

- deception of the perception of size. This deception is based on erroneous estimates of the geometric magnitude of the object, which can be caused by the surrounding background, as well as other objects located side by side. The correct way to not make a mistake in this case is to use a ruler. It turns out that the wrong estimate of the size can be 25 percent or more;
