【摘要】 近视在我国发病率较高，是影响儿童视觉健康的重要因素。现有的研究表明，过长的屏幕使用时间和过少的户外活动是儿童近视的重要诱因，这些危险因素都与光照参数，如光照强度、时常、频率、光谱有关。并且，不当的夜间照明也会对儿童的昼夜节律、睡眠产生影响并导致近视。现对屏幕时间、户外活动、光照属性以及昼夜节律的临床研究以及流行病学资料进行综述，为儿童近视预防提供一些建议与指导。更多还原

【Abstract】 The prevalence of myopia is substantial in China, significantly impacting children’s visual health. Current research indicates that extended screen time and inadequate outdoor activities are pivotal factors contributing to childhood myopia. These risk factors are closely associated with light parameters, including intensity, duration, frequency and spectrum. Moreover, inappropriate nighttime lighting can disturb children’s circadian rhythms and sleep and contribute to myopia development. This study reviews clinical research and epidemiological data on screen time, outdoor activities, light properties and circadian rhythms, aiming to offer recommendations and guidance for preventing myopia in children.更多还原
