Computer vision syndrome and associated factors among secretaries working in ministry offices in Addis Ababa, Ethiopia

Background: Prolonged use of computers led users to risk of computer vision syndrome (CVS). CVS is one of the occupational health problems. The aim of this study was to assess CVS and associated factors among secretaries working in government ministry offices in Addis Ababa, Ethiopia. Materials and Methods: Institution-based cross-sectional study was conducted. Data were collected using interviewer administered pretested structured questionnaire and ophthalmic examinations. A total of 455 secretaries were participated in the study. Binary logistic regression analysis was applied to investigate determinants associated with CVS. Variables with p-value <0.05 were considered statistically significant. Results: The prevalence of CVS among secretaries working in ministry offices in Addis Ababa was 68.8%. The main reported symptoms were blurred vision (36.9%), eye strain (32.1%), redness of the eye (27.3%) and headache (26.4%). Average monthly income (AOR=0.453, 95% CI: 0.235–0.874), habit of frequent voluntary blinking (AOR=0.313, 95% CI: 0.150–0.655), taking regular breaks between work (AOR=0.279, 95% CI: 0.078–0.996), using computer eye/glasses/ spectacles (AOR=0.451, 95% CI: 0.245–0.830), sources of light at work place (AOR=0.009, 95% CI: 0.001–0.076), using an antiglare filter (AOR=0.216, 95% CI: 0.117–0.401) and knowledge (AOR=0.212,95% CI:0.115–0.389) were significantly associated with CVS. Conclusion: Prevalence of CVS among secretaries was high. Average monthly income, habit of voluntary blinking, taking regular break, using computer spectacles, sources of light at work place, using an antiglare filter and knowledge were significantly associated with CVS. The findings suggest the need for adjusting exposure time to computers and increase awareness on safety measures and regular eye screening.
