One in three children worldwide is now nearsighted, a significant increase in recent years. The study said the increase was 'notable' after the height of the COVID-19 pandemic, pointing to lockdowns that sent many children to learn online indoors. Factors contributing to this rise include increased screen time, reduced outdoor activity, and changes in lifestyle and education. Experts emphasize the importance of regular eye exams and encouraging outdoor play to help mitigate the growing prevalence of myopia, as long-term effects can impact children's vision and quality of life.
