EMF Radiation Level and Asthenopia Prevalence among Computer Users in Uyo Urban, South-South, Nigeria

Abstract

In this study, a cross-sectional survey design was used to investigate the prevalence of asthenopic symptoms among 354 computer users with respect to the level of EMF radiation from computer monitor screens. The results of the study revealed a significant association between the risks and the radiation level as well as a significant increase in angle of gaze between those affected and unaffected users. It was found that frequent/severe headache (59.1%) was the most complained symptom followed by chronic eye irritation (41.5%). The findings in this work, if properly taken into consideration, will help to create social awareness and also help relevant authorities as well as individuals in the policy formulations regarding their ergonomics.
