Computer Vision Syndrome Before and After the SARS-CoV-2 Pandemic: New-Symptom Onset and Workplace Setup of Visual...

Area of Science:

• Ophthalmology
• Public Health
• Ergonomics

Background:

• The SARS-CoV-2 pandemic led to widespread remote work, increasing reliance on visual display terminals (VDTs).
• This shift potentially altered the prevalence and onset of computer-vision syndrome (CVS) due to varied home-office setups.
• Understanding the link between VDT setup and new-onset CVS is crucial for public health.

Purpose of the Study:

• To investigate the association between visual display terminal (VDT) workplace setup and the new onset of computer-vision syndrome (CVS) symptoms.
• To identify specific VDT setup factors contributing to CVS after the SARS-CoV-2 pandemic.

Main Methods:

• A cross-sectional online survey was conducted.
• Computer-vision syndrome (CVS) was assessed using the standardized CVS-Q questionnaire.
• VDT workplace setup was evaluated individually and via a comprehensive VDT risk score, with logistic regression used for analysis.

Main Results:

• The overall prevalence of CVS was 42.7%, with oculomotor dysfunction symptoms being particularly affected.
• Inadequate home-office equipment and higher VDT exposure were associated with increased CVS risk.
• An inadequate VDT score significantly increased the odds of developing CVS (OR = 1.78).

Conclusions:

• Inadequate home-office VDT setups are associated with a higher risk of new-onset computer-vision syndrome.
• Effective preventive strategies for CVS require addressing environmental and equipment factors in home workspaces.
• Further ophthalmological research is needed to establish targeted preventive measures.
