Key Points Question Was myopia development in children reversed or worsened after the COVID-19 lockdown in Hong Kong? Findings In this cross-sectional study of 20 587 children, after COVID-19 restrictions were lifted, myopia prevalence was still high, and time spent outdoors, near-work time, and screen time did not return to pre–COVID-19 levels. Younger children and children from low-income families were at a higher risk of myopia during the pandemic. Meaning The study’s findings suggested that increasing time spent outdoors and reducing screen and near-work time may prevent burgeoning postpandemic myopia, particularly among younger children and children from low-income families.
