PURPOSE: To investigate the relationship between digital screen time and the development and progression of myopia during the 2019 coronavirus disease (COVID-19) pandemic.
METHODS: Children aged 7-18 years who had regular refractive measurement follow-ups before and after the COVID-19 pandemic were included in the study. They were divided into two groups according to their initial refractive status, emmetropic and myopic. The relationship between spherical equivalent refraction (SER) changes and digital screen time before and after the pandemic was analyzed.
RESULTS: A total of 255 children were included in the study. During the pandemic in the emmetropic group, digital screen time increased by 5.98 ± 2.13 h/day, and the mean SER decreased from - 0.02 to - 0.55 D (p < 0.001). During the pandemic in the myopic group, the digital screen time increased by 6.25 ± 2.36 h, and the mean SER decreased from - 1.82 to - 2.72 D (p < 0.001). A significant correlation was found between the increase in digital screen time and the change in SER in the emmetropic and myopic groups (r = - 0.261, p = 0.015, r = - 0.269, p = 0.001, respectively).
CONCLUSION: Increased digital screen time during the COVID-19 pandemic is associated with a myopic shift in emmetropic children and myopic progression in myopic children. As a result of COVID-19, increasing cases of myopia should be addressed as a public health concern.
