ABSTRACT
There is little or no evidence that operators who have worked on VDUs for many years show any permanent damage to their eyes. The evidence, however, suggests that the use of VDUs leads to problems of discomfort rather than problems of health. Many different studies have shown that VDU operators have reported the following symptoms of eye strain or eye fatigue: loss of visual sharpness; difficulty in focusing; seeing colour fringes; double vision; grittiness; dryness; burning; redness; watering; and aching.
