Selection of glasses for vision. Prices, reviews, ratings
General information
Using special glasses for vision correction is also a medical procedure, which, although not an intervention in the internal work of the eye itself, significantly affects the implementation of the visual function. There are many indications for the use of glasses, as well as many target applications:
- reading glasses;
- computer glasses;
- glasses that allow you to correct myopia or hyperopia;
- glasses for drivers.
For medical use, glasses are united by one main function - to provide the patient with maximum acuity of stereoscopic and binocular vision.
An experienced ophthalmologist selects glasses taking into account all the nuances of certain pathologies of the patient, since even the same eye disease can proceed completely differently.
Contact lenses have become no less popular now, which have a number of advantages: they do not limit peripheral vision, do not fog up, and also perform a cosmetic function. But glasses are still relevant due to their ease of use and the absence of direct contact with the eyes, which is unpleasant for the patient.
The essence of vision correction, which is carried out with glasses, is to artificially focus light rays on the retina, compensating for the patient's vision defects thanks to the shape of the lenses. The eye disease itself, whether it is myopia or hyperopia, does not go away, but glasses compensate for the harmful effect of these diseases, preventing their progression (vision loss due to a decrease in the visual part of the brain) and helping the patient maintain a normal rhythm of life.
Procedure
Preparation
Preparation for this procedure is a comprehensive vision diagnosis, during which the ophthalmologist must not only make sure of the need for a particular type of vision correction, but also learn all the nuances of the patient's visual system, including:
- checking the refractive power of the ocular apparatus;
- identifying the dominant eye;
- studying the patient's accommodation and convergence;
- analysis of binocular vision patient.
The process of selecting glasses
Having accurately determined the diagnosis and all its accompanying subtleties of an individual nature, the ophthalmologist begins to select lenses for glasses using an experimental method. In fact, all the preparation was reduced to narrowing the search field for the most optimal lenses for glasses in terms of their effectiveness. During the process of selecting lenses, the patient is given a choice of several options, and he, having assessed the corrective effect of each, chooses the best one. In addition, a frame for glasses is selected, which should be comfortable and aesthetically pleasing.
Rehabilitation period
As a rule, the selection of glasses does not require a rehabilitation period, but when correcting astigmatism, cylindrical lenses used require getting used to.
Complications after the procedure
The correct selection of glasses does not carry the risk of complications. However, an inexperienced ophthalmologist may make a mistake in the procedure, which may lead to eye fatigue, great strain or even deterioration of vision.
Indications
The selection of glasses is indicated for diseases of the ocular apparatus, the essence of which lies in the incorrect focusing of light rays, for example:
- farsightedness;
- myopia;
- astigmatism.
Contraindications
There are no special contraindications for the selection of glasses, but the patient's age, individual tolerance of the frame and the appropriateness of this type of vision correction should be taken into account.
Prices and clinics
Glasses are selected by an experienced ophthalmologist either in a specialized clinic or in a city hospital. There is a practice in which an ophthalmologist selects lenses, writes a prescription, and the patient buys glasses with the correct lenses and the necessary frame in a specialized optics store. Prices depend on the frame and the location of the procedure.
