Field of View Anatomical

The anatomical field of view (abbreviated as PZA) is the area of ​​space that our eye can cover while at rest. This concept is used in the anatomy of the eye and plays an important role in the study of the human visual system.

The PZA can be described as a cone-shaped volume that is formed by the eye at rest. It has the shape of a torus, the upper part of which is wider than the lower part. The upper border of the PZA corresponds to the upper edge of the visual field, and the lower border corresponds to the lower edge of the visual field.

The size of the PZA can vary from person to person and depend on factors such as age, gender, and the presence of eye diseases. Typically, in a healthy person, the vertical PZA angle is about 60 degrees, and the horizontal angle is about 90 degrees. This means that a person can see objects with a width of up to 90 degrees horizontally and up to 60 degrees vertically, located at a distance of 1 to 6 meters.

It is important to note that PZA refers to the concept of relative vision, that is, the area of ​​​​space that a person can cover with his vision without moving his eyes. However, with eye movement, the PZA can expand significantly, reaching a diameter of up to 180 degrees.

Studying PZA allows us to better understand how the human visual system works and what capabilities a person has to perceive information from the surrounding world. This knowledge can be useful in medicine, in diagnosing eye diseases, as well as in technical areas related to the development of devices for improving vision, for example, in the creation of virtual and augmented reality.

Thus, the anatomical visual field is an important concept in the study of the human visual system. It defines the area of ​​space that our eye can cover at rest, and is of great importance for understanding the capabilities of human vision.

The anatomical field of view is the space that the eye sees when the head and eyeballs are stationary. It is limited by the limits of the light cone, i.e. a cone emanating from the middle of the field of view with its apex in the eye of the observer, and called the polarizing sphere. This sphere is created by the refractive media of the eye, the accommodative system of the eye and the lens. In the center of the visual field is the optical center or image of the macula, as well as the blind spot.

The field of view is anatomically considered to be relatively equal triangular, with an angle of 60 degrees at the apex. Within this triangle, three separate areas can be distinguished. In this case, horizontal lines form an isogonal figure, which helps when considering the shape of the field of view from the periphery to the center. Let's depict it using posters, which are ideal symmetrical images using isoconic and isolateral transformations.
