Computer Vision Syndrome (CVS) is developed among computer workers due to long time working with computers or viewing of the video display terminal (VDT). The objective of this study is to determine the magnitude and determinants of CVS symptoms among IT officers.
A cross sectional study of IT office workers was conducted at Kathmandu from March to April 2019. Self-administrated questionnaire and observation of researcher was applied to collect information. CVS defect was considered if the participants were having minimum of one symptom during /following use of VDT. The proportion of CVS and its association with different independent factors was carried out.
The prevalence of CVS reported by 263 participants was 82.5% (95% CI: 81.3% - 83.6%), of them 163(62.0%) were not aware about bad effects of computers to the visual apparatus. Goggles were used as protection against CVS by 140(53.2%) participants. CVS symptoms included headache 127(48.0%), tired eyes 123(47.0%) and eye strain 114(43.0%). Use of computer for more than 4.75 hours/day experienced CVS. The mean office work included 7.7 ± 2.02 hours computer work. The video display gadgets usage in home was 2.7 ± 2.35 hours/ day. Not taking breaks (OR:7.3; 95% CI:2.2 - 24.9), not massaging eyes (OR:7.5; 95% CI:1.2 - 47.7), unusual viewing distance (OR:9.0; 95% CI:2.0 - 44.5), improper posture (OR:3.6; 95% CI:1.3 - 10.3), computer usage for more than 10 hours/ day (OR:5.4; 95% CI:1.6 - 18.2) and not aware of CVS (OR:7.2; 95% CI:2.6 - 20.3) were significant predictors of CVS in IT workers.
Most of the IT workers had CVS. Health education and care of IT workers based on predictors found need to be strengthened in the study area.
计算机视觉综合征（CVS）是由于长时间使用计算机或观看视频显示终端（VDT）而在计算机工作者中发展起来的。本研究的目的是确定 IT 人员中 CVS 症状的严重程度和决定因素。
2019 年 3 月至 4 月，在加德满都进行了一项 IT 办公室工作人员的横断面研究。应用自我管理问卷和研究者观察收集信息。如果参与者在使用 VDT 期间/之后至少有一种症状，则认为存在 CVS 缺陷。进行 CVS 的比例及其与不同独立因素的关联。
263 名参与者报告的 CVS 患病率为 82.5%（95%CI：81.3%-83.6%），其中 163 名（62.0%）不知道电脑对视觉器官的不良影响。140 名（53.2%）参与者使用护目镜作为预防 CVS 的措施。CVS 症状包括头痛 127 例（48.0%）、眼睛疲劳 123 例（47.0%）和眼睛疲劳 114 例（43.0%）。每天使用计算机超过 4.75 小时会出现 CVS。平均办公时间包括 7.7±2.02 小时的计算机工作。在家中使用视频显示小工具的时间为每天 2.7±2.35 小时。不休息（OR：7.3；95%CI：2.2-24.9）、不按摩眼睛（OR：7.5；95%CI：1.2-47.7）、不寻常的观看距离（OR：9.0；95%CI：2.0-44.5）、不正确的姿势（OR：3.6；95%CI：1.3-10.3）、每天使用计算机超过 10 小时（OR：5.4；95%CI：1.6-18.2）和不知道 CVS（OR：7.2；95%CI：2.6-20.3）是 IT 工作人员 CVS 的显著预测因素。
大多数 IT 工作人员都患有 CVS。需要加强基于研究区域中发现的预测因素对 IT 工作人员进行健康教育和护理。
