Myopia has rapidly increased from 23% to 34% globally from 2000 to 2020 and could reach 50% by 2050. It poses serious risks, including myopic maculopathy and retinal detachment. Genetic factors, particularly family history, significantly influence myopia onset. Increased educational demands and near work are major environmental contributors. Time outdoors acts as a protective factor, reducing myopia incidence by up to 45%. This critical public health issue requires action from clinicians and educators to mitigate risk, especially in genetically susceptible children.
