Abstract

The global burden of myopia continues to expand, and the prevalence of myopia in East Asian populations is of particular concern. With the substantial increase in screen-based electronic devices, screen time has emerged as a potential risk factor. This review examined the relationship between screen viewing duration and myopia risk and public health strategies to reduce screen exposure among children. We conducted an evidence-based review of only meta-analyses investigating screen time and myopia association, searching PubMed from inception to January 20, 2025. Four of the six meta-analyses reviewed supported an association between prolonged screen use (> 2 or 3 hours/day) and increased myopia risk. However, methodological limitations include the predominance of cross-sectional study designs, self-reported screen time measurements, and the lack of cycloplegic refraction in some studies within the meta-analyses. Current public health strategies focus mainly on banning mobile phones in schools and limiting screen time. Technology-based solutions, such as anti-addiction systems, support and complement these strategies. Healthcare providers play a crucial role in assessing screen time patterns in children and providing evidence-based recommendations. Future studies should employ objective screen time measurements, conduct longitudinal analyses with cycloplegic refraction, and evaluate the effectiveness of screen time interventions in myopia prevention through randomized controlled trials. In addition, examining the combined effects of traditional near-work activities and screen time may provide more comprehensive insights into myopia risk factors.
从证据到行动:减少屏幕时间和减轻近视风险的公共卫生方法。
全球近视负担持续扩大,东亚人群的近视患病率尤其令人担忧。随着屏幕电子设备的大量增加,屏幕时间已成为一个潜在的危险因素。本综述探讨了屏幕观看时间与近视风险之间的关系以及减少儿童屏幕暴露的公共卫生策略。我们进行了一项基于证据的荟萃分析,调查了屏幕时间和近视之间的关系,检索了PubMed从成立到2025年1月20日的数据。6项荟萃分析中有4项支持长时间使用屏幕(每天2小时或3小时)与近视风险增加之间的关联。然而,方法学上的局限性包括横断面研究设计的优势,自我报告的屏幕时间测量,以及在meta分析中的一些研究中缺乏睫状体麻痹性屈光。目前的公共卫生战略主要侧重于禁止在学校使用移动电话和限制屏幕时间。以技术为基础的解决方案,如反成瘾系统,支持和补充了这些战略。医疗保健提供者在评估儿童屏幕时间模式和提供基于证据的建议方面发挥着至关重要的作用。未来的研究应采用客观的屏幕时间测量,对睫状体麻痹性屈光进行纵向分析,并通过随机对照试验评估屏幕时间干预在近视预防中的有效性。此外,研究传统的近工作活动和屏幕时间的综合影响可能会为近视的风险因素提供更全面的见解。

期刊介绍: The Asia-Pacific Journal of Ophthalmology, a bimonthly, peer-reviewed online scientific publication, is an official publication of the Asia-Pacific Academy of Ophthalmology (APAO), a supranational organization which is committed to research, training, learning, publication and knowledge and skill transfers in ophthalmology and visual sciences. The Asia-Pacific Journal of Ophthalmology welcomes review articles on currently hot topics, original, previously unpublished manuscripts describing clinical investigations, clinical observations and clinically relevant laboratory investigations, as well as .perspectives containing personal viewpoints on topics with broad interests. Editorials are published by invitation only. Case reports are generally not considered. The Asia-Pacific Journal of Ophthalmology covers 16 subspecialties and is freely circulated among individual members of the APAO’s member societies, which amounts to a potential readership of over 50,000.
