Introduction
Seeing is a very complex process that has not yet been fully explained in detail. Light is transmitted to the brain in electrical form as information and processed accordingly. In order to understand vision, some terms should be known, which are explained briefly below: What is light?
What is a neuron? What is the visual pathway? What are the optical visual centers?

What is seeing?
Seeing with the eyes is the visual perception of light and its transmission to the visual centers in the brain (CNS). This is followed by the evaluation of the visual impressions and a possible subsequent reaction to them. The light triggers a chemical reaction in the eye on the retina, which produces a specific electrical impulse that is transmitted via nerve tracts to higher, so-called optical brain centers.
On the way there, i.e. already in the retina, the electrical stimulus is processed and prepared for the higher centers in such a way that they can handle the information supplied accordingly. In addition, the psychological consequences resulting from what has been seen must also be taken into account. After the information has become conscious in the visual cortex of the brain, an analysis and interpretation takes place.
A fictitious model for the representation of the visual impression is created, with the help of which the concentration is directed to specific details of what is seen. The interpretation is strongly dependent on the individual development of the viewer. Experiences and memories involuntarily influence this process, so that each person creates his or her “own image” from a visual perception.
