随着科技的发展，电子设备在工作和生活中的使用日益增加，人们对各种视频显示终端的依赖日趋增强。眼表是视觉系统抵抗外部环境损伤的第一道屏障，长时间暴露于视频显示终端会引起畏光、异物感、眼干和眼疲劳等干眼症状，其中视频显示终端所发出的可见光中又以波长在400-500 nm的蓝光能量最高，可能是导致干眼的罪魁祸首。尤其近年所爆发的新冠疫情，让各式各样的线上活动呈爆发式增长，人们使用视频显示终端的频率和时间明显增加。这也促进了全球对视频显示终端发射的蓝光所致干眼的研究。文章就近年来长时间使用视频显示终端引起干眼的研究进展进行归纳，并从发病情况、发病机制、预防和治疗等方面进行综述。

[Abstract]
With the development of science and technology, electronic devices have become an inevitable part of our daily life and work. There has been an increase of interest in the use of various video display terminals(VDT). The ocular surface is the first barrier of the visual system to resist the damage of the external environment. In recent years, the number of patients with dry eye has consistently increased with the excessive use of VDT. Blue light produced by VDT, with wavelengths ranging from 400 to 500 nm, has a high energy in visible light. Therefore, blue light may also be an important risk factor for dry eye. In particular, the outbreak of COVID-19 has left people worldwide suffering from increased blue light, which promotes further research into dry eye caused by blue light emitted from VDT. In this review, we summarize the recent studies on the role of blue light produced by VDT in dry eye to provide reference for future related research.
