Abstract

Some of the vision problems associated with the use of computers have been attributed to poor ergonomic factors compliance. The aim of this study was to investigate the ergonomic factors that might lead to computer vision syndrome (CVS) among non-presbyopic computer users in a University staff population. A complete eye examination was performed on each participant before he or she was interviewed using a structured questionnaire probing into demographic status and factors that could lead to CVS. Eighty seven participants were included in the study. An observation and measurement of the participant's computer workstation was then made in order to identify the risk factors leading to CVS. Data were analysed with descriptive statistics. 72% of participants reported taking breaks after 2 hours while 28% reported taking breaks after every hour of computer use. Eye strain and visual fatigue (89%), headaches (81%), neck and back pains (77%) were the most severe and frequently reported symptoms among the participants. In general, the computer workstations were not ergonomically designed and users were not aware that they were not adhering to ergonomic requirements for computer use. This suggests the need for awareness campaigns on ergonomic factors that can prevent computer vision syndrome among computer users and early intervention programs for computer users that experience computer vision syndrome.
