“…Chang et al reported accelerated myopic progression during the COVID-19 pandemic lockdown in children and teenagers, which was partially reversed after lockdown, suggesting that both accommodative spasm and structural changes contributed to this accelerated rate ( 32 ). However, digital eye strain is a result of the current restriction measures that have led to an imposed home confinement ( 33 ). Visual fatigue can also induce acute acquired concomitant esotropia, which was reported during the COVID-19 pandemic ( 34 ).…”

This study aimed to review the consequences of increased online learning, which was precipitated by the coronavirus disease 2019 (COVID-19), on visual function, as well as the methods for preventing the associated visual impairment. The recent finding implies that a higher incidence of myopia may be observed during the pandemic than that before. The myopia prevalence was 59.35% in COVID-19, which was higher than that in the normal period. COVID-19-related influence of developing myopia among students should be addressed and under control. Online learning precipitated by COVID-19 is likely to increase the global burden of visual function impairment. This review highlighted useful measures to prevent online learning-related visual function impairments, including the following: (1) desktop illumination of no >300 lx, online learning time for primary, and middle-school students of no more than 20–30 min per session; (2) daily video time for preschool children not exceeding 1 h, and for school-age children and adolescents not exceeding 2 h; (3) after every 30–40 min of online learning, moving eyes away from the screen or closed for 10 min; (4) engaging in outdoor activities for ≥ 2 h a day; (5) suitable screen and learning environment settings and correct postures for reading and writing; (6) sufficient sleep and proper nutrition. Preventing online learning-related visual impairment during and after this unprecedented pandemic will facilitate future ophthalmic practice.

“…If excessive exposure to technologies predisposes to negative consequences during the pandemic [31], their conscious use could be quite beneficial for maintaining the health of the population. In this sense, the effective implementation of telehealth services is a useful tool for physical and mental well-being, especially for patients with chronic conditions [32].…”

Numerous preventive measures of social distancing and lockdowns have been imposed by governments and health authorities in order to reduce severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. This, in turn, has significantly impacted upon physical activity levels and other healthy habits in different countries around the globe, which may precipitate several negative sequalae on the health of the world population. Here, we briefly discuss the current scientific evidence on the subject and propose relevant recommendations moving forwards.

“…Во время пандемии COVID-19 c 2020 года школьники вынужденно были переведены на дистанционное обучение, соответственно увеличилось время их пребывания за компьютером, телефоном и другими гаджетами. Связанные с пандемией коронавируса ограничения и постоянный контакт с мониторами негативно сказываются на зрении детей, особенно отрицательная динамика отмечена при миопии [9][10][11][12]. Исследования, проведенные в Гонконге, доказывают, что, чем меньше времени дети проводят на свежем воздухе и больше занимаются делами, требующими напряжения глаз, тем сильнее у них ускоряется развитие близорукости.…”

Введение. В последние годы в нашей стране и за рубежом отмечается тенденция к увеличению частоты миопии, которая приобретает в некоторых странах характер эпидемии. Связанные с пандемией коронавируса ограничения и постоянный контакт с мониторами негативно сказываются на зрении детей, особенно отрицательная динамика отмечена при миопии.Цель исследования. Провести анализ динамики миопии у школьников после дистанционного обучения во время пандемии COVID-19.Материалы и методы. Проведен анализ 500 амбулаторных карт пациентов с миопией. Возраст детей – от 7 до 13 лет. Анализировались показатели рефракции по сфероэквиваленту, биометрия глаза. Полученные данные были разделены на два периода наблюдения: I – до пандемии 2018–2019 гг., II – во время дистанционного обучения при пандемии – 2020–2021 гг.Результаты. При всех степенях миопии отмечена отрицательная динамика по увеличению годичного градиента прогрессирования после начала дистанционного обучения. Средняя продолжительность онлайн-занятий (r=−0,27, P<0,0001), количество онлайн-уроков в день (r=−0,33, P<0,0001), а также время воздействия цифрового экрана (r=−0,20, P<0,0001) отрицательно коррелировали с полученной рефракцией (сфероэквивалент) и средним временем пребывания на открытом воздухе.Выводы. Увеличение длительности пребывания за цифровым экраном способствует прогрессированию миопии у детей и подростков во время пандемии COVID-19. Рекомендованы назначение более строгого зрительного режима с перерывами каждые 30–40 минут и прогулка на улице не менее 2 часов во время светового дня, чтобы предотвратить пандемию миопии. In recent years, in our country and abroad, there has been a tendency to an increase in the frequency of myopia, acquiring the character of an epidemic in some countries. The restrictions associated with the coronavirus pandemic and constant contact with monitors negatively affect the vision of children, especially negative dynamics were noted in myopia.The purpose of the study. To analyze the dynamics of myopia in schoolchildren after distance learning during the COVID-19 pandemic.Materials and methods. An analysis of 500 outpatient records of patients with myopia was carried out. The age of children is from 7 to 13 years old. Spheroequivalent refractive indices and eye biometrics were analyzed. The data obtained were divided into two observation periods: I – before the 2018–2019 pandemic, II – during distance learning during the pandemic 2020–2021.Results. For all degrees of myopia, negative dynamics was observed in increasing the annual gradient of progression after the start of distance learning. Average duration of online lessons (r=−0.27, P<0.0001), number of online lessons per day (r=−0.33, P<0.0001), and digital screen exposure time (r=−0.20, P<0.0001) negatively correlated with the obtained refraction and the mean time spent outdoors.Conclusions. Increasing the length of time spent behind a digital screen contributes to the progression of myopia in children and adolescents during the COVID-19 pandemic. It is recommended to prescribe a stricter visual regime with breaks every 30–40 minutes and walk outside for at least 2 hours during daylight hours to prevent a myopia pandemic.
