The aim of the study was to measure the prevalence and intensity of eye symptoms in office workers who use computers on a regular basis, and to find out if the symptoms depend on the duration of computer use and other work-related factors.
Office workers employed at large social services companies in two cities (Warszawa and Katowice) were invited to fill in a questionnaire (cross-sectional study). The questions included work history and history of last-week eye symptoms and eye-related complains. Altogether 477 men and women returned the completed questionnaires. Between-group symptom differences were tested by the chi-square test and verified by the results of multivariate logistic analysis. The examined effects included the role of daily computer use and lighting conditions at work stations.
The examined persons complained of such eye symptoms as eye strain, visual acuity impairment and mucosal dryness or eye burning. The following values of symptom prevalence were found in women and men, respectively: eye strain 50.7% and 32.6%, disturbed visual acuity 38.3% and 21.2%, mucosal dryness and eye burning 46.5% and 24.2%. The results of multivariate analysis confirmed the statistically significant effects of lighting intensity and screen flickering on the occurrence of symptoms.
Frequent occurrence of eye symptoms and their associatation with some characteristics of the work environment point to the need of observing ergonomic standards of work stations and of the usage of computers at work.
本研究旨在测量经常使用电脑的办公室职员眼部症状的患病率及严重程度，并探究这些症状是否取决于电脑使用时长及其他与工作相关的因素。
邀请了两个城市（华沙和卡托维兹）大型社会服务公司的办公室职员填写问卷（横断面研究）。问题包括工作经历以及上周的眼部症状和与眼睛相关的抱怨。共有477名男女返回了填写完整的问卷。组间症状差异通过卡方检验进行测试，并通过多因素逻辑分析结果进行验证。所研究的影响因素包括每日电脑使用情况和工作场所的照明条件。
受调查者抱怨出现眼疲劳、视力下降以及黏膜干燥或眼睛灼痛等眼部症状。女性和男性的症状患病率分别如下：眼疲劳50.7%和32.6%，视力受损38.3%和21.2%，黏膜干燥和眼睛灼痛46.5%和24.2%。多因素分析结果证实了照明强度和屏幕闪烁对症状发生有统计学意义上的显著影响。
眼部症状频繁出现及其与工作环境某些特征的关联表明，需要遵守工作场所和工作中使用电脑的人体工程学标准。
