Abstract:
Objective:To investigate the effects of online learning on children's vision. Methods We collected the vision data of children from the Huainan area recorded during December 1-31, 2019 (before online learning) and from December 31, 2020 to January 31, 2021 (after online learning) in Affiliated Ophthalmic Hospital of Anhui University of Science and Technology. These data were divided into three groups according to different age brackets: primary school (6-12 years, n = 1 124), middle school group (> 12-15 years, n = 552), and junior high group (> 15-18 years, n = 554). The change in vision after online learning relative to before online learning was analyzed using SPSS 22.0 software. Results Before online learning, the overall incidence of myopia was 52.70%, the incidence of myopia was 25.31% for 6-12 years old, 71.89% for > 12-15 years old, and 88.34% for > 15-18 years old. After online learning, the overall incidence of myopia was 62.40%, the incidence of myopia was 40.25% for 6-12 years old, 78.60% for > 12-15 years old, and 91.88% for > 15-18 years old. There were significant differences in the prevalence of myopia in each age bracket between before and after online learning ( χ2 = 21.44, P < 0.001). Conclusion Online learning greatly affects the vision of adolescents. Corresponding measures should be formulated to strengthen the prevention and control of myopia in children.
