Abstract

   Objective: To investigate the prevalence of computer vision syndrome (CVS) and associated factors of CVS among office workers in three factories. Material and Methods: A cross sectional study was conducted. One hundred and fifty seven office workers were investigated from three factories in Phrapradaeng District, Samutprakarn Province during September to October 2019. Demographic data, symptoms of CVS and its associated factors were collected by self-administered questionnaires. Logistic regression analysis was performed. Results: Of 157 factory workers, mean age was 40.99 10.19 years and 66.9% of the subjects were females. The prevalence of CVS was 86.0%. The ocular symptoms (at least one symptom of headache, blurred near vision, blurred distant vision, dry eyes, sore or irritated eyes, red eyes, excessive tearing, double vision, eyelid twitching or changes in visualizing colors for at least 1 week in the past 12 months) were found in 146 (93.0%). The most prevalent ocular symptom was sore or irritated eyes (69.2%). The extraocular symptoms (at least one symptom of wrist pain, neck pain, shoulder pain or back pain for at least 1 week in the past 12 months) were found in 145 (92.4%). The educational level at least Bachelor’s degree (OR 4.21), using computers for 2 to 4 hours/day (OR 5.38), using computers for 4 to 8 hours/day (OR 6.87) and using computers for more than 8 hours/day (OR 4.72) were significantly associated with CVS (p-value<0.05). Conclusions: The investigation showed high number of CVS among office workers in three factories. The educational level at least Bachelor’s degree and using computers for more than 2 hours/day were significantly associated with CVS. To prevent CVS, education on ergonomic knowledge, optimizing exposure time, regular visual break, improving awareness on CVS and management support should be provided for the office workers and other related departments in the factories.
