Self-reported Computer Vision Syndrome Among Bank Workers in Onitsha, Nigeria.

Abstract

This study aimed to determine the awareness, prevalence, and pattern of ocular problems related to computer [computer vision syndrome (CVS)] use among bank workers in Onitsha, Nigeria. This was a cross-sectional study involving bank staff in Onitsha metropolis who were selected using a simple random technique. A validated CVS questionnaire was used to obtain information on sociodemographic characteristics, frequency and duration of computer use, eye symptoms, and preventive measures. There were 150 bank staff selected: 81 (54.0%) females and 69 (46.0%) males, aged 20-49 years (mean= 33.2 ± 7.2 years). All participants used computer daily. Daily computer use was 1-16 h. Seventy-nine (53.4%) workers were aware of CVS; 127 (84.7%) used preventive measures which included anti-reflective eye glasses (12.7%) and computer screen guard (22.3%). Symptoms with computer use were reported by 103 (68.7%) participants. The prevalence of CVS was 29.3%. Headache (45.4%), itching (38.6%), photophobia (38.0%), visual blur (37.3%), and eye pains (28.0%) were the commonest symptoms. There was a trend towards CVS being commoner in female gender (P = 0.059), with prolonged computer use, and failure to use preventive measures. CVS is 6-fold more likely to occur in individuals who wear corrective lenses. CVS is common among the bank workers studied. Use of protective measures that minimize exposure to electromagnetic force radiation from computer screens is suggested. A computer screen guard is recommended as a minimum preventive measure for long-term computer users.
