Computer and visual display terminals syndrome is a constellation of symptoms ocular as well as extraocular associated with prolonged use of visual display terminals. This syndrome is gaining importance in this modern era because of the widespread use of technologies in day-to-day life.

2020年2月5日 · This cross-sectional study estimated computer vision syndrome (CVS) prevalence and analysed its relationship with video display terminal (VDT) exposure, as well as sociodemographic, refractive, environmental, and ergonomic characteristics in 109 presbyopic VDT workers wearing progressive addition lenses (PALs).

2024年11月7日 · This study evaluated the effect of VDT on visual fatigue through a meta-analysis system, aiming to guide prevention of visual fatigue caused by VDT and regulating VDT operation. A total of 16 research articles were included, designed to provide deeper insights.

The present study showed that VDT usage at work was associated with an increased risk of headache/eyestrain. Additionally, the use of VDT increased the risk of suspected CVS patients in white-collar workers and pink-collar workers.

什么是VDT？ Visual Display Terminal（VDT）综合征，全称为“视频显示终端综合征”，是由于长时间使用VDT操作（电脑、电视、手机、iPad屏幕等）而影响眼睛和身心健康的一组疾病，又被称为“技术紧张性眼病”或“电脑视力综合征（Computer Vision Syndrome，CVS）”。

近年来，随着科技的发展，视频终端视疲劳综合征（VDTS）的发病率不断上升。 大部分视频终端操作者在长时间注视屏幕后，常以"眼干、眼痛、头昏、视物模糊"等症状就诊。 目前，VDTS的发病机制尚不清楚，可能是多种因素共同作用的结果，比如工作环境、显示器画质、操作姿势等。 随着使用者的低龄化，VDTS的危害日益严重，因此如何采取相应的预防和治疗措施是当前亟待解决的问题。 本文归纳总结了近年来国内外关于VDTS治疗的相关研究，提供了改善视频终端操作 …

2023年1月9日 · In this study, we explored the relationship between the usage of VDT including various devices, and symptoms related to CVS in a large population including pink-collar workers and blue-collar workers.

In this study, sex, body posturing, use of electronics devices out of work, habit of taking breaks, visual display terminal (VDT) use in hours, distance from the screen, knowledge, and general ergonomic practice were factors associated with CVS.

2015年6月1日 · The results obtained show that the CVS questionnaire (CVS-Q) has acceptable psychometric properties in VDT workers. The questionnaire includes 16 symptoms that are scored using two rating scales, one for frequency and the other for intensity.

2023年7月3日 · The final version of the Chinese scale to measure CVS was obtained (the CVS-Q CN©). The mean age of participants was 31.3 ± 9.8 years, 47.6% were women, and 57.1% used VDTs to work for more than 8 h/day. The CVS-Q CN© can be considered an easy tool to assess CVS in workers exposed to digital devices in China.
