Determinants of Computer Vision Syndrome among Bank Employees in Minia City, Egypt

Background: There is growing body of evidence that use of computers can adversely affect
the visual health. Objective: To study the frequency and risk factors of computer vision
syndrome (CVS) among bank employees in Minia. Method: Community-based crosssectional
study of 218 bank employees who work on computer for at least one year preceding
the date of the study. Two hundred and eighteen (218) computer workers working in seven
different banks were selected randomly. Subjects were asked to fill a pre-tested structured
questionnaire, and other relevant information was obtained by personal interview and
inspection of workstation. Results: Among the 218 subjects studied, 85.2% suffer from ocular
complaints. Headache (24.8%), eye strain (20.2%), diminution of vision (16.9%) were the
most common ocular complaints and they have significant associations in subjects working
for more than 4 hours, keeping a distance less than 20 inch from the computer, who do not
take breaks and do not adjust the brightness. Conclusions: Prevalence of CVS was noted to
be quite high among bank employee. Headache, eye strain, diminution of vision, blurred
vision, double vision, itching and burning sensation were the factors independently associated
with CVS.
