Working in Comfort
Further Suggestions
•
Have your eyes checked on a regular basis and ensure your eyeglass
prescription is suitable for working on a display screen.
•
Look away from the screen from time to time to help reduce eye
strain. Focus on distant objects briefly. Also, blinking periodically
helps lubricate the eyes.
•
Avoid holding your muscles tensed for long periods of time. Keep
your fingers and body relaxed.
•
Changing tasks frequently will help prevent muscle stiffness. For
example: alternating between using the keyboard, writing, filing, and
moving around in your work environment, helps keep muscles loose.
•
When prolonged screen work is required, take frequent short breaks.
As a rule of thumb, a five or ten minute break every hour is a good
idea. Short frequent breaks are more beneficial than longer less
frequent breaks. Data shows that people who work for long lengths
of time without a break are more prone to injury.
•
Occasionally stretch the muscles in your hands, arms, shoulders,
neck and back. You should stretch at least as often as you take your
breaks, that is, at least once per hour.
•
Discomfort, if any, may be alleviated by use of alternative ergonomic
designs and accessories such as: ergonomic personalized chairs,
wrist rests, keyboard trays, alternative input devices, non-
prescription eye glasses, glare screens, and more. Seek additional
information from the sources available to you, including your
employer, doctor, local office supply store, and the bibliography
provided at the end of this section.
•
If you experience any discomfort, discontinue use and see a doctor
as soon as possible. If you want additional information on VDT setup,
ergonomics and related topics, consult your employer and the
sources listed at the end of this section.
