School-Based Myopia Prevention Effort—Reply

Abstract

Time spent outdoors is well recognized as a factor preventing the development of myopia onset, and measures including adding an outdoor class, locking classroom doors during class recess, or glassed roof and walls incorporated in a classroom have been developed. But promotion to increase time spent outdoors as a school-based intervention program remains challenging especially in East Asia. • Near work activity has been suggested as a risk factor for myopia although the evidence is not entirely consistent. The total duration of near work activity may not be as important as the type of near work activity. Core techniques to implementing interventions of near work activities include effective measures of near work-related parameters, real-time data analyses, and alert systems.
