Aim The aim of this study was to determine whether students’ exposure to digitally projected, multimedia teaching material under naturally varying classroom lighting conditions is associated with myopia risk and severity. Design A population‐based, cross‐sectional study in 2012 of children in grades 4–6 across 87 schools in Taiwan. Methods Students ( N = 3,686) reported demographic information, outdoor time, physical activity and near work. Parents provided their myopia status. Student‐reported multimedia teaching frequency and classroom lighting levels were confirmed with direct observation. School nurses conducted vision screening and ophthalmologist referral. Myopia status and severity were measured by spherical equivalent refraction; SE ≤−0.5 dioptres was coded as myopic. Binary logistic and tobit regression were used to estimate the contributions of classroom multimedia exposure and lighting to myopia risk and severity controlling for risk factors. Results/Findings Age, parental myopia and hours of near work increased the odds of myopia and predicted greater severity. Physical activity and outdoor time predicted lower risk and severity. Multimedia exposure in relatively bright classrooms was associated with greater odds of myopia. Classroom lighting levels during multimedia teaching were inversely related to severity; exposure frequency was unrelated. Conclusions Multimedia exposure under brighter classroom conditions may contribute to the myopia incidence in schoolchildren. Impact Teaching with digital projection technology is increasingly prevalent. This may increase children's odds of developing myopia, which has far‐reaching and lifelong deleterious effects. School nurses should raise awareness of and promote strategies that reduce this risk, including working with children, parents, school personnel and system leaders to adopt eye‐healthy behaviours, practices and policies.
