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 groups.

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 regularly.,

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
