Description

The invention relates to ophthalmology, in particular to devices for training vision, and can be used to restore or improve the vision of people with myopia by training the muscular apparatus of the eyes.

A device for training vision is known (RF patent No. 2077253, class A61B 3/00, publ. 1997), including eyepieces with a viewing hole.

In the known device, the inspection openings are made in eyepieces of opaque materials.

A disadvantage of the known device is that it is difficult to work saccade automation in natural mode - large saccades cause discomfort due to the opacity of the eyepiece. The eye is forced into saccade mode of small amplitude (micro-saccades), while saccades of large amplitude (macro-saccades) carry the visual axis out of the visible field, which leads to intense static fixation of the eyes. This, in turn, leads to rapid fatigue of the muscular apparatus of the eyes, and prolonged static stay of the eyes in one position reduces the effectiveness of the training process.

The objective of the present invention is to develop a tool that eliminates these disadvantages, namely, to reduce the fatigue of the oculomotor apparatus, to create natural conditions for the manifestation of saccade automation, to expand the scope and environment of use, thereby increasing the effectiveness of treatment.

The technical result consists in increasing the efficiency of the training process by minimizing the amplitude of saccades in a gentle mode and providing visual orientation by bringing the treatment process closer to natural visual perception by using a translucent eyepiece and creating conditions for the manifestation of saccade automation in a natural mode, combining saccades of small amplitude (microsaccades), and saccades of large amplitude (macroscades).

The result is achieved in that in the device for training vision, including eyepieces with a viewing hole, the eyepieces are made of darkened transparent material, the distance between the viewing holes in the eyepieces is comparable (equal) to the interpupillary distance of a particular patient, while the diameter of the viewing hole is made in the range of 0.5 -3.0 mm, and the fact that the intensity of the darkening of the eyepieces is different, and the fact that the eyepieces are made with diopters, and the fact that the eyepieces are made without diopters.

The eyepieces are made of convex glass or plastic with a degree of obscuration of 50 to 75%, with or without diopters, with holes whose diameter is made in the range from 0.5 to 3 mm, the distance between the holes in the eyepieces should be equal to the interpupillary distance of a particular patient . All these indicators of Owl glasses allow them to be used to treat myopia.

The device is shown in the drawing and contains a frame 1 with eyepieces 2 with viewing holes 3. In the frame 1 inserted eyepieces 2 made of glass with blackout, in the center of which holes 3 are made with a diameter of 0.5 to 3.0 mm, the distance between which is equal to interpupillary distance of a specific patient. The doctor writes a prescription to the patient indicating the interpupillary distance and the percentage of blackout. For example, the average dimming is 50% or the maximum dimming is 75%, with or without diopters. The patient, as usual, chooses a frame and gives it along with the prescription to the optician, who immediately makes Filin’s glasses and passes them to the patient.

Instructions for using glasses is as follows. At the end of the day or in his spare time, the patient takes off his glasses and puts on the owl’s glasses, looks into the distance through the holes with two eyes, trying to examine small objects. You can watch TV. These glasses are designed to train the muscles of the eye. After training, the patient can use his glasses. It should be noted whether it became better or worse in their glasses after a 10-minute workout. During the day, the patient can wear training glasses several times.

In stationary conditions, the doctor uses these glasses in conjunction with other methods to treat myopia and relieve spasm of accommodation. The results of the study of visual acuity in 10 patients before and after applying the owl glasses are shown in the table.

The table shows that the use of Owl glasses improves vision.

Thus, Owl glasses have a therapeutic effect, improve visual acuity, increase the reserve of accommodation. In 10 patients the increase in visual acuity was 0.1-0.4, and in only two cases there was no increase in visual acuity. Owl glasses received a positive rating from patients. Of the 10 people, 7 noted some relief after applying glasses, and 4 disappeared fatigue. It should be noted that this is after short-term use - no more than one month. There is reason to believe that prolonged use will give great results.

Thus, the use of Filin's glasses allows to increase the efficiency of the training process by minimizing the saccade amplitude in a gentle mode and providing visual orientation by using the natural amplitude of saccade automation and simplifying the training process by bringing the treatment process closer to natural visual perception.
