Abstract

Background: Computer vision syndrome (CVS) is a common condition in the digital era, causing fatigue in users exceeding four hours of screen time daily. It manifests as blurred vision, itching, dryness, and eye fatigue. This study examined the prevalence and risk factors for CVS among university students.

Methods: A cross-sectional survey was conducted among 230 students using simple sampling. A structured questionnaire included: (1) demographic data, (2) digital device use and ergonomic habits, and (3) CVS symptom frequency and severity based on the validated CVS-Q© scale.

Results: A total of 76.1% of the participants were found to have CVS, with a higher prevalence among female students (80.2%) compared to male students (70.7%). 87.4% of the subjects (n = 201) experienced one or more symptoms of CVS. Most of them experience headaches (60.4%, n = 139), eye irritation (55.7%, n = 128), tearing (50.9%, n = 116), and discomfort in the eyes (49.6%, n = 114). Female students scored a higher mean of CVS than male students (p = .004). Risk factors were a lack of adequate rest between screen watching periods (p ≤ .001) and failure to observe the 20-20-20 rule (p = .015).

Conclusion: The study indicates that the prevalence of CVS is extremely high among the students, and, therefore, there is a need for ergonomic interventions to be implemented widely and used for prevention or alleviation of symptoms of CVS.

伊朗大学生电脑视觉综合症患病率及影响因素：一项横断面研究。

背景：计算机视觉综合征（CVS）是数字时代的一种常见疾病，每天使用屏幕时间超过4小时会导致用户疲劳。它表现为视力模糊、瘙痒、干燥和眼睛疲劳。本研究探讨大学生CVS患病率及危险因素。方法：采用简单抽样法对230名学生进行横断面调查。结构化问卷包括：(1)人口统计数据；(2)数字设备使用和人体工程学习惯；(3)基于经验证的CVS- q©量表的CVS症状频率和严重程度。结果：共有76.1%的参与者被发现患有CVS，其中女生的患病率（80.2%）高于男生（70.7%）。87.4%的受试者（n = 201）出现一种或多种CVS症状。其中以头痛（60.4%,n = 139）、眼睛刺激（55.7%,n = 128）、流泪（50.9%,n = 116）、眼睛不适（49.6%,n = 114）居多。女生的CVS平均得分高于男生（p = 0.004）。危险因素是在观看屏幕期间缺乏足够的休息（p≤0.001）和未能遵守20-20-20规则（p = 0.015）。结论：研究表明，大学生CVS患病率极高，因此，需要广泛实施人体工程学干预措施，预防或缓解CVS症状。
