Optometry: vision measurement and correction

Optometry is the branch of medicine that deals with measuring and correcting vision. She uses various methods and technologies to determine the quality of vision and identify possible problems associated with visual function. Optometry helps determine the presence of myopia, farsightedness, astigmatism, presbyopia and other eye diseases.

The main tool of optometry is an optometric device that allows you to measure visual acuity, determine the refractive error of the eye and select optical means to correct it. There are various types of optometric instruments such as autorefractometers, foreptometers, lensometers and others. Each of them has its own characteristics and is used depending on the purpose and objectives of the optometric examination.

Optometry is an important part of the diagnosis and treatment of eye diseases. It helps to identify not only refractive errors of the eye, but also other problems, such as impaired binocular vision, difficulty in shifting focus from near to distant objects and vice versa, as well as other problems associated with the functioning of the eye muscles.

In addition, optometry allows you to determine the need to wear glasses or contact lenses and select the optimal means to correct them. There is now a wide range of optical options available, including different types of spectacle lenses and contact lenses, allowing you to choose the most suitable solution for each patient.

In conclusion, optometry is an important field of medicine that measures and corrects vision. It helps to identify possible problems associated with visual function and select the most appropriate means to correct them. Optometry can preserve visual function and improve the quality of life of patients.

Optometry is a field of medicine that deals with measuring and analyzing the visual function of the eye. It plays an important role in the diagnosis and treatment of many eye-related diseases.

Eye optics studies the structure, optical properties and function of light rays perceived by the eye. The subject of its study is light energy passing through the organ of vision from the entrance hole of the pupil to the optical plane of the retina. The optics of the eye comes into contact with a number of other branches of science.

One of the main branches of eye optics is geometric optics. This section studies the properties of light rays along the path to the eye and behind the eye up to the retina in directions close to parallel. Most ophthalmological techniques for studying the refractive system of the eye are based on geometric optics methods, including techniques such as pupillography, retinoscopy, autorefractometry and keratotopography.

Another branch of eye optics is physical optics and spectral analysis of light. This section explores subtle issues of the interaction of electromagnetic radiation with molecules of eye tissue - its interaction with light is studied by biooptics, microscopy and analysis of the reflection of light from a section of the cornea of ​​the eye, making it possible to identify individual changes in the cornea, indicating disturbances in the internal structure of the eye.

When considering issues of the optics of the human eye, one should not confuse objects related to ophthalmology with optics used for scientific research purposes. They have different goals and different histories.
