Objective This study aimed at evaluating refractive changes in German school-aged children before and after the COVID-19 pandemic.Design Cross-sectional study.Setting 414 eye care professional centres from Germany.Participants Refractive data from 59 926 German children aged 6–15 years were examined over a 7-year period (2015–2021).Primary and secondary outcome measures Spherical equivalent refraction was assessed as a function of year, age and gender. The refractive values concerning 2020 and 2021 were compared with those assigned to prior years (2015–2019).Results The refractive data associated with 2020 and 2021 showed a myopic refractive shift of approximately −0.20D compared with the 2015–2019 range. The refractive change was statistically considerable in the 6 to 11-year range (p |
