Impact of various types of near work and time spent outdoors at different times of day on visual acuity and refractive error among Chinese school-going children

摘要

BackgroundVarious types of near work have been suggested to promote the incidence and progression of myopia, while outdoor activity appears to prevent or retard myopia. However, there is a lack of consensus on how to interpret these results and translate them into effective intervention strategies. This study examined the association between visual acuity and time allocated to various activities among school-going children.
