Computer-related vision problems in Osogbo, south-western Nigeria
Widespread use of computers for office work and e-learning has resulted in increased visual demands among computer users. The increased visual demands have led to development of ocular complaints and discomfort among users. The objective of this study is to determine the prevalence of computer related eye problems and their associations among computer users in Osogbo, South Western Nigeria. A written semi-structured questionnaire was used to collect information on computer related symptoms among bankers, office workers and students in Osogbo, South Western, Nigeria. A total of 416 respondents completed and returned the questionnaire. All the respondents had at least one computer related symptom. The most prevalent symptom was neck and shoulder pain which was reported by 62% computer users. Backache and headache were reported by 60.8% and 58.4% of the respondents respectively. Blurring of vision while working on the computer was the commonest symptom that stopped respondents while using computers. No significant association was found between symptom scores and gender, duration of computer use, type of computer screens, and use of screen filter. Symptom scores were significantly related to presence of pre-existing eye problems. Symptoms were also related to ergonomically inappropriate workstation environments of respondents. Computer related vision symptoms occur frequently among computer users in South Western Nigeria. Improvement in workstation environments of computer users and treatment of pre-existing eye problems require attention to prevent occurrence of epidemics of computer related visual problems in this part of the world.
