Abstract
The aim of this study: to identify and analyze changes in the lifestyle and psychological sphere of students who are undergoing online training in quarantine isolation due to the COVID-19 pandemic.
 Material and methods: 160 students were examined for the myopic refraction using the Duochrome Test, as well as shifts in the quality of vision as a result of online learning. All participants were also interviewed to ascertain living conditions and psychological status during domestic learning related to COVID-19 isolation.
 Result: it was found that 42.5 % participants have myopia, most of them students of 1 and 4 courses (26.5 % and 30.9 %, respectively). 85.6 % respondents noted deterioration in health after long-term visual work with personal computer and/or smartphone. The leading symptoms associated with work on digital displays were: decreased visual acuity and binocular vision disorders (81.9 %), headache (75.6 %), back muscle pain (71.9 %), eyes redness (55.6 %), dry and itchy eyes (45 % of respondents). It has been established what 75.6 % respondents indicated deterioration in their psychological condition as a result of quarantine restrictions: 68.1 % – stress, 48.8 % – emotional instability (irritability), 51.9 % – sleep disorders (insomnia), 16.3 % – depression. It is determined that daily average working time in the conditions of domestic online learning was 6.4±2.6 hours (compared to 4.1±1.7 hours in the pre-quarantine period).
 Conclusion: revealed deterioration in the quality of vision, general well-being and the psychological sphere of students who are undergoing online quarantine training due to the COVID-19 pandemic.

Summary
There is no doubt that the COVID-19 Acute Respiratory Disease Pandemic has serious consequences in various spheres of life, and the restrictive measures introduced to combat the spread of the SARS-CoV-2 virus have radically changed the way of life and the individual, and the world community in general. Even at the beginning of the COVID-19 pandemic, scientists and health professionals expressed reservations about the possible long-term effects of COVID-19 disease and anti-epidemiological measures, the possible negative impact of the long-term use of electronic devices on the health of all participants in the educational process. According to the results of this survey, the most common symptoms exacerbated by DED during the pandemic were: eye fatigue (84 %),
