Abstract
Objective: To investigate health and safety risks
related to computer use among software professionals.
Methodology: This cross-sectional survey was
undertaken among Lahore software professionals. The
questionnaire has sensitivity and specificity over 70%
and achieved good test-retest repeatability both for the
scores obtained [ICC = 0.802; 95% confidence interval
(CI): 0.673, 0.884] and CVS classification (κ = 0.612;
95% CI: 0.384, 0.839). All participants were subjected
to a binary logistic regression analysis using the
dichotomous dependent variable of „presence of
computer vision syndrome‟ and the continuous/
dichotomous independent variables of age, gender,
duration of work, and daily computer usage. In
addition, the frequency, percent, cross-tabulation,
charts. Chi-square, and binary logistic regression
models were applied. The data were analyzed using
the SPSS version 25.
Results: Out of 112 subjects, 62.5% were male and
37.5% female. Mean age was 25.51 ± 4.23 (range 17 –
45). Out of 112 subjects, 68.8% had computer vision
syndrome.
Conclusion: Computer vision syndrome is common
in software professionals, which needs adjustments in
the work place.
