Prevalence and Associated Factors of Computer Vision Syndrome Among the Employees of a Selected University in Mangaluru, Karnataka- A Cross-sectional Study

Objectives Computer vision syndrome (CVS) refers to the physical discomfort and visual fatigue that occur from prolonged use of digital screens. Among employees, this is often caused by extended periods of computer work without adequate breaks, poor lighting, improper screen positioning, or uncorrected vision issues. This study aimed to assess the prevalence and to identify the associated factors of CVS among employees. Material and Methods A cross-sectional study was conducted at Yenepoya (Deemed to be University) in Mangaluru, Karnataka, over 1 year from August 2022 to 2023. A total of 160 employees were selected through a non-probability purposive sampling method. Data collection involved a demographic proforma, a CVS questionnaire, and a checklist on associated factors of CVS. The gathered information was analysed using both descriptive and inferential statistical methods. The association was assessed using the Chi-square test. Results Most participants were aged 25–30 years (40%) and predominantly female (60.6%); the majority were second division clerical staff (56.9%). About 25% had mild and 3.8% had moderate CVS. Inappropriate computer-use practices were common, including suboptimal seating posture, limited use of blue lens spectacles and anti-glare screens, and inconsistent blinking habits. Significant associations were observed between ergonomic visual factors and selected demographic variables ( p <0.05). Conclusion The study found that 28% of participants experienced mild to moderate symptoms of CVS. To effectively address this issue, it is essential to regulate screen exposure time, mitigate ergonomic risks linked to computer use through both on-the-job and off-the-job training programs, and ensure that safety guidelines are available and accessible to all university staff members.
