Students of a special medical group for vision during regular physical training with using special exercises with a shuttlecock and the use of badminton elements are able to improve and stabilize actuty of vision.

Introduction
At the present stage of development of society, the major attention is paid to the development of information technology, global computerization. To be in demand in society, profession and training, it is necessary to comprehensively develop and constantly be in the process of self-education, and getting new knowledge. Large flows of information pass through the visual analyzer [2].
In order to remain competitive throughout life, it is necessary to provide constant recreational activities for the whole organism, but also pay special attention to maintaining the ability to sharply see and quickly process the data [2, 3].
Due to this, the development of technologies and techniques for physical recreation with the ability to train and restore vision is especially relevant. For the correction and prevention of visual impairment, badminton in combination with special exercises with a shuttlecock is considered the most affordable and effective means [1, 4].
Research methods and organization.
The study involved 12 university students aged 17-22 years assigned for health reasons to a special medical group of vision correction.
Diagnosis of vision was carried out on a Tonoref II autorefkeratotonometer. Statistical analysis of the results of the study was carried out using the program IBM SPSS Statistics 25.
Results and its discussion.
Students were examined twice: once at the beginning of the experiment, the second after three months of training in a special group at training sessions in the discipline of applied physical education using special exercises with a shuttlecock and corrective elements when playing badminton. Classes were held 3 times a week for 45 minutes. After the first examination, the following results were found in a group of subjects: V OD / OS, 0.3 / 0.3, ± V OD / OS, 0.5 / 0.5. The differences between the indicators are significant at p <0.01.
At the end of the experiment, the following indices were found in the examined group: V OD / OS, 0.6 / 0.6, ± V OD / OS, 0.8 / 0.8 (p <0.05). A high increase in the level of dexterity revealed during the pedagogical testing using the ball for tennis was also noted. Hitting the target and catching the ball, both with the leading hand and the secondary one, was estimated. Testing results before the experiment (4.1 ± 0.3 points), after (7.2 ± 0.5 units), which characterizes a high level of development of motor potential with increasing of visual acuity.
The analysis of the materials showed that out of 12 students involved in physical exercises with badminton elements, six students increased their visual acuity by 10% from the initial level, four students by 20%. At the same time, vision was restored in one subject and stabilization of the process was observed in two individuals (differences were significant at p <0.05).
Conclusion
The results of the study suggest that it is advisable to use special exercises with a shuttlecock and badminton elements at least three times a week when combined with other developing physical exercises to improve vision.
