Description

 The invention relates to the field of medical technology and can be used to correct visual defects and treat various eye diseases.

 An optical device is known for preoperative cataract patients, containing a frame in which an opaque mask is inserted, a horizontal transparent section crosses the mask at the eye level, below which there is a mask section with a system of circular, discrete transparent holes with diameters from 0.5 to 1.2 mm, the location of the transparent areas is such that their total aperture increases in those areas of the mask that correspond to a greater distance from the eye to the mask and a greater angular deviation from the line of sight forward (US patent N 4249803, G 02 C 7/16, publ. 10.02.81).

 A disadvantage of the known device is the location of the holes only in the lower part of the mask.

 Known are “stenopic glasses” containing a spectacle frame in which neutral light filters with a central hole or a perforated raster are installed (USSR copyright certificate N 164986, publ. 10/14/1964).

 A disadvantage of the known "stenopic glasses" is the limited size of the hole pattern and the disordered arrangement of the holes in it, thereby reducing the therapeutic effect of these glasses.

 The objective of the invention is the creation of an optical device for the correction of visual defects and the treatment of eye diseases.

 The technical result is an increase in contrast and clarity of the image, increased motor activity and refractive ability of the eye, correction of color perception.

The result is achieved by the fact that the optical device for vision correction includes a frame, inserts with a system of holes, while the inserts are painted with the ability to absorb light flux with a wavelength of 380
800 n. m. and the holes are made in the form of polygons and / or ovals and are located throughout the area of the inserts or the area occupied by the system of holes is a polygon.

 The area occupied by the holes is from 0.01 to 0.9 of the total area of the insert.

 In the proposed optical device for vision correction, the color of the inserts and the shape of the holes are selected depending on the disease and the individual characteristics of the eyes.

 So, the choice of color of the inserts is due to the color vision of a person and a specific disease, when the ability of the eye to perceive the entire spectrum of visible radiation is lost. The color of the inserts is regulated by spectral permeability, which is in the range of 380 800 nm. and provides the perception of the color of objects by persons with impaired color perception, and also eliminates the annoying effect of the spectrum bands associated with the disease.

 In the proposed optical device, the inserts are made with a system of holes through which light passes to the eye and enters the retina.

 In this case, the luminous flux entering the outer surface of the inserts splits into narrow beams according to the number of holes located on the inserts.

 The beam of light passing through the holes becomes coherent and is characterized by a high directivity and high energy density.

 Due to the high intensity of the light flux at the entrance and exit from the hole, the light beam acts like a lens, "contracting" to the optical axis, that is, it self-focuses, providing enhanced image clarity and refractive ability of the eye without accommodation.

 The use of holes in the form of polygons allows you to repeatedly enhance and regulate these phenomena due to the "uneven" surface formed by faces and vertices.

 By varying the shape of the polygons, that is, the number of faces and vertices, the preferred effect of the light flux is achieved depending on the optical aberrations (deviations from the norm) of the eye.

 The use of oval-shaped openings provides a softer effect on the retina.

 The combination of holes of various types on one insert provides the correction of visual defects of several diseases at the same time.

 The ratio of the holes of various types is selected experimentally and provides an optimal effect on the eyes.

 In FIG. 1, 2, 3 shows an optical device with holes in the form of triangles, ovals.

 An optical device for correcting vision includes: a frame 1, an insert 2 with holes 3.

An optical device for correcting vision works as follows:
The light beam entering the inserts 2 inserted into the frame 1 for ease of use, passing through the holes 3, enters the eyes. As a result of exposure to the retina of the eye with a highly directional, high-energy light beam, various physicochemical processes occur that can significantly improve vision and treat specific eye diseases.

 Using the proposed optical device allows you to correct optical aberrations, improve color perception, enhances motor activity of the muscles surrounding the eye, relieves eye fatigue, treats myopia, hyperopia, astigmatism, strabismus and other diseases.
