What can be done to make the use of a VDT more effective?
To make the most of a VDT it should be placed in an area in which the room and screen are matched for brightness; the glare from windows, lights and shiny surfaces is reduced to minimum; and the operator is seated 475 mm (19 in.) from the screen. Other factors include the placement of the work copy at a viewing angle comfortable to the operator and the use of chair with an adjustable back and seat.
What work habits should a VDT operator adopt?
Proper posture and head position are important in reducing muscle strain. Since the eye muscles must increase their workload when viewing work at close range, work breaks are also important. Generally, a fifteen minute break every two hours of VDT use is recommended. However, these relief strategies will not be as effective if the operator's visual system is not functioning at its best.
What should I do if I experience headaches, fatigue or other changes in vision clarity?
ACT! Arrange for a vision examination as soon as possible if you experience any new or persistent symptoms such as headache, fatigue, dizziness, eyestrain, eye irritation or a change in your vision.
