TIPS FOR COMFORTABLE COMPUTING
When using a computer as part of your job--or even for personal tasks--it's
easy to spend a long time sitting in one position
looking at the screen. Just as the best running shoes can't prevent physical
problems if you run too much, even an ideal computer setup can't prevent
fatigue and soreness if you sit at your desk for hours at a time.
It may take some conscious effort and discipline on your part, but it
is important to take frequent breaks- even if they're only of short duration-
to rest your eyes and move your body. Stand up and stretch. Walk around.
And try to organise your work throughout the day so that you alternate
using your computer with other activities that don't use the same muscle
If your eyes feel dry while you're using the computer, blink them a number
of times or close them tightly for several seconds. As with any visually
intensive activity, to prevent muscle fatigue that can lead to blurred
vision and headaches, occasionally look at objects much further away than
the display--6 metres or more. Of course, make sure you're wearing the
right glasses or contact lenses if you need them, and have your eyes examined
And always, if you experience persistent pain while using your computer,
consult a qualified health professional. Better yet, ask your health advisors
for suggestions on developing healthy work habits now to prevent problems
in the future
