Abstract

Visual display terminal (VDT) work has become a major part of operation in majority of workplace. This study aimed to eye fatigue in video display terminal users and its relation to sleep disorders. This cross-sectional study was done on 209 computer users who work more than one year in this field. All participants completed a questionnaire about their age, sex, BMI, years of experience, and hours of daily computer use. A standardized visual fatigue questionnaire was used for detection presence and severity of eye strain. Sleep quality was used to assess Pittsburg Sleep Quality Questionnaire (PSQI) , and the Epworth Sleepiness Questionnaire (ESS) to assess daytime sleepiness in participants. Insomnia was assessed by Insomnia Severity Index (ISI).
The most common eye symptoms including eye fatigue (65.5%), eyelid heaviness sensation (69.4%), eye irritation (67.2%), dry eye (67.8%), blurred vision (68.5%), and tearing (68.1%) were significantly higher in participants who were working more than 8 hours with DVT in day. There was a significant correlation between scores of eye fatigue and insomnia severity (Rho=0.32, P<0.05).
According to results, the prevalence of eye symptoms particularly eyelid heaviness sensation and blurred vision was high. However, eye fatigue was more affected insomnia severity in VDT users. Therefore, it is needed to protect computer users from the adverse effects of VDT. Implementing proper ergonomic programs to the workplace are important for achievement to good physical and mental health among VDT users.
