Computer vision syndrome (CVS) is the most pressing public health concern that affects vision and reduces quality of life and productivity, particularly in developing countries. Most of the previous studies conducted in Ethiopia focus on the knowledge and personal risk factors of bank workers. Moreover, ergonomic workstation design was not objectively assessed, which could hinder the implementation of effective intervention strategies. Therefore, this study aimed to determine CVS and ergonomic factors among commercial bank workers in Addis Ababa, Ethiopia.
An institutional-based cross-sectional study was carried out among 466 study participants from May 26 to July 24, 2022. A multistage sampling technique was applied to select the study participants. Data were collected via a standardized tool of CVS (CVS-Q). Besides, workstation ergonomics were pertinently assessed. The collected data was entered into EpiData version 3.1 and exported to SPSS version 26 for data analysis and cleaning. Multivariable logistics regression analysis was performed to identify factors associated with CVS. The variables with a -value < 0.05 were considered statistically significant factors.
Prevalence of CVS was 75.3% (95% CI: 71.2-79.2%). Blurred vision, eye redness, and headache, 59.8%, 53.7%, and 50.7%, respectively, were frequently reported symptoms. Glare (AOR = 4.45: 95% CI: 2.45-8.08), 20-20-20 principle (AOR = 1.98, 95% CI: 1.06-3.67), wearing non-prescription eyeglasses (AOR = 4.17; 95% CI: 1.92-9.06), and poor workstation (AOR = 7.39; 95% CI: 4.05-13.49) was significantly associated with CVS.
The prevalence of CVS was found to be high. Glare at work, ignoring the 20-20-20 principle, wearing non-prescription eyeglasses, and poor workstation ergonomic design were independent predictors of CVS. Therefore, comprehensive interventional activities like adhering to the 20-20-20 principle, avoiding the use of non-prescription glasses, minimizing glare, and improving workstation ergonomic setup are essential to prevent CVS.
计算机视觉综合征（CVS）是影响视力、降低生活质量和生产力的最紧迫的公共卫生问题，尤其是在发展中国家。之前在埃塞俄比亚进行的大多数研究都集中在银行工作人员的知识和个人风险因素上。此外，工作场所的工效学设计并未得到客观评估，这可能会阻碍有效干预策略的实施。因此，本研究旨在确定埃塞俄比亚亚的斯亚贝巴商业银行工作人员中的 CVS 和工效学因素。
2022 年 5 月 26 日至 7 月 24 日，采用基于机构的横断面研究方法，对 466 名研究对象进行了研究。采用多阶段抽样技术选择研究对象。通过 CVS-Q 标准工具收集 CVS 数据。此外，还对工作站工效学进行了评估。收集的数据输入到 EpiData 版本 3.1 中，并导出到 SPSS 版本 26 中进行数据分析和清理。采用多变量逻辑回归分析确定与 CVS 相关的因素。具有 - 值 < 0.05 的变量被认为是具有统计学意义的因素。
CVS 的患病率为 75.3%（95%CI：71.2-79.2%）。分别有 59.8%、53.7%和 50.7%的人经常报告视力模糊、眼睛发红和头痛等症状。眩光（AOR = 4.45：95%CI：2.45-8.08）、20-20-20 原则（AOR = 1.98，95%CI：1.06-3.67）、佩戴非处方眼镜（AOR = 4.17；95%CI：1.92-9.06）和工作场所不佳（AOR = 7.39；95%CI：4.05-13.49）与 CVS 显著相关。
研究发现 CVS 的患病率较高。工作场所的眩光、忽视 20-20-20 原则、佩戴非处方眼镜和工作场所工效学设计不佳是 CVS 的独立预测因素。因此，坚持 20-20-20 原则、避免使用非处方眼镜、减少眩光和改善工作场所工效学设置等综合干预活动对于预防 CVS 至关重要。
