Gamma Angle in Physiological Optics

The Gamma angle in physiological optics is an important parameter for understanding the human visual system. It determines the angle that is formed between the visual line passing through the pupil of the eye and the optical axis that passes through the center of the cornea.

The Gamma angle plays an important role in the perception of depth and distance of objects, as well as in determining the direction of eye movement. When the eye looks at an object, the Gamma angle can change depending on the distance to the object and the angle of its inclination.

Normally, the Gamma angle should be about 15 degrees. However, if the Gamma angle is too small or too large, it can lead to various vision problems such as nearsightedness or farsightedness.

To determine the Gamma angle, it is necessary to conduct an ophthalmological examination, which includes measuring the Gamma angle using a special device - an autorefractometer. During the examination, the doctor evaluates the Gamma angle and other parameters of the visual system, which makes it possible to make an accurate diagnosis and prescribe appropriate treatment.

Thus, the Gamma angle is an important indicator for understanding the functioning of the visual system and determining its disorders. Regular examination and monitoring of the Gamma angle can help prevent the development of various visual disorders and improve people's quality of life.

In optical physics, one important formula stands out, which is called the “Gamma angle”. The formula represents the relationship between different straight lines, but at the same time has a significant impact on the optics of human vision. The Gamma angle turned out to be a completely reasonable element from a physiological point of view. This angle is of great importance in optical practice, therefore it is an integral part of many studies in the field of anatomy of the visual apparatus.

The Gamma angle is equal to the ratio of the length of the segment that connects the human eye and the eyeball to the distance from the eye to the object in question. The length of the segment is visually close to 3 diagonals of a square, the sides of which are measured perpendicular to the optical axis of the eye and the visual line. Thus, the length of this segment will consist of the sum of the middle lines, which are formed by diagonals connecting each other. This amount is quantitatively close to the upper limit of up to 26 millimeters.

In a healthy person, the Gamma angle fluctuates in the range of 45 degrees. With prolonged reading, the upper limit decreases to approximately 38 degrees, and the lower one takes values ​​within the range of 54-55 degrees. For nearsighted people, both of these values ​​will decrease while reading the book.
