This bad lighting condition might be a possible reason for the high
rate of eye problems/eyestrain reported in this study.
Previous studies have shown that computer users are
at greater risk of developing eye problems and visual
fatigue in relation to the position of the screen
(Ankrum & Nemeth, 1995; Ijadunola et al., 2003).
This study also revealed that only few respondents had their
computer room well lit and ventilated, thereby causing
them more strain — especially visual strain.
Only few made use of a cordless keyboard and mouse which
means they always have to be close to these tools,
thereby restricting their mobility during computer
work. This goes a long way towards igniting pain.
