1From the Institute for Prevention and Occupational Medicine of the German Social Accident Insurance, Institute of the Ruhr University Bochum, Bochum, Germany (T.B., I.H., S.C.); Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA), Sankt Augustin, Germany (S.G., K.W., B.W., R.E.); German Social Accident Insurance Institution for the Woodworking and Metalworking Industries (BGHM), Düsseldorf, Germany (C.C.) and German Social Accident Insurance Institution for the administrative sector (VBG), Hamburg, Germany (J.P., B.N.).
Objective:
This cross-sectional online survey investigated the associations between the setup of visual display terminals (VDT) and the new onset of symptoms associated with computer-vision syndrome (CVS) after the SARS-CoV-2 pandemic.
Methods:
CVS was assessed by the standardized CVS-Q questionnaire. Items of VDT workplace setup at home were assessed individually as well as by a comprehensive VDT risk score. New onset and exacerbation of CVS symptoms were modeled using logistic regression, adjusting for various confounders.
Results:
The overall CVS prevalence was estimated as 42.7%. Symptoms associated with oculomotor dysfunction were particularly affected. An inadequate home-office equipment, several variables related to VDT exposure, and an overall inadequate VDT score (odds ratio = 1.78; 95% conflict of interest 1.10-2.78) were associated with increased risks for CVS.
Conclusions:
To define effective preventive measures will be a major challenge for future ophthalmological research.
