Digital eye strain (DES) is a growing occupational and public health problem and one of the most frequent reasons for seeking medical care. The objectives of this study are to identify the prevalence and to study some associated personal, ergonomic, and environmental factors of DES among information technology (IT) professionals at Tanta University, Egypt. An interview questionnaire was used to collect data related to socio-demographic, job, ergonomic and environmental characteristics. Computer vision syndrome questionnaire (CVS-Q) was used for the assessment of DES. It was used to measure ocular and visual symptoms related to computer use. CVS-Q includes 16 symptoms that are scored using two rating scales, one for frequency and the other for intensity. A total of 108 IT professionals were included. Prevalence of DES was 82.41%. The most common symptoms were headache (81.5%), burning of the eye (75.9%), and blurred vision (70.4%). Significant predictors of DES were female gender (OR = 2.845), age ≥ 35 years (OR = 1.112), daily computer use more than 6 h (OR = 1.351), duration of work more than 10 years (OR = 1.793), wearing corrective glasses (OR = 5.009), distance from the monitor less than 20 in. (OR = 4.389), not using antiglare screen (OR = 0.214), no brightness adjustment of screen (OR = 0.015), not taking break time during computer work (OR = 0.007), exposure to air pollution (OR = 5.667), use of the air conditioner (OR = 23.021), and exposure to windy environments (OR = 3.588). Prevalence of DES was found to be high among IT professionals. Significant predictors of DES were female gender, older age, wearing eyeglasses, long duration of computer use, unadjusted ergonomic workstation, and dry environment. DES is a problem that can be prevented by increasing knowledge and awareness about DES by providing computer users with eye health education, periodic training on a proper ergonomic computer workstation, and adjustment of the suitable comfortable workplace environment.
数字眼疲劳（DES）是一种日益严重的职业和公共卫生问题，也是寻求医疗的最常见原因之一。本研究的目的是确定埃及坦塔大学信息技术（IT）专业人员中 DES 的流行程度，并研究一些与个人、人体工程学和环境相关的因素。使用访谈问卷收集与社会人口统计学、工作、人体工程学和环境特征相关的数据。使用计算机视觉综合征问卷（CVS-Q）评估 DES。它用于测量与计算机使用相关的眼部和视觉症状。CVS-Q 包括 16 种症状，使用两种评分量表进行评分，一种用于频率，另一种用于强度。共有 108 名 IT 专业人员被纳入研究。DES 的患病率为 82.41%。最常见的症状是头痛（81.5%）、眼睛灼热（75.9%）和视力模糊（70.4%）。DES 的显著预测因素包括女性（OR=2.845）、年龄≥35 岁（OR=1.112）、每天使用计算机超过 6 小时（OR=1.351）、工作年限超过 10 年（OR=1.793）、戴矫正眼镜（OR=5.009）、显示器距离小于 20 英寸（OR=4.389）、不使用防眩光屏幕（OR=0.214）、不调整屏幕亮度（OR=0.015）、在计算机工作期间不休息（OR=0.007）、暴露于空气污染（OR=5.667）、使用空调（OR=23.021）和暴露于多风环境（OR=3.588）。研究发现，IT 专业人员中 DES 的患病率很高。DES 的显著预测因素包括女性、年龄较大、戴眼镜、长时间使用计算机、未调整的人体工程学工作站以及干燥的环境。通过为计算机用户提供眼部健康知识教育、定期进行适当的人体工程学计算机工作站培训以及调整舒适的工作场所环境，可以预防 DES 这一问题。
