Apple Workgroup Server 8150/110 - Manual (Page 107)

m Arrange the monitor so that the top of the screen is slightly below your eye
level when you’re sitting at the keyboard. The best distance from your eyes
to the screen is up to you, although most people seem to prefer 18 to 28
inches (45 to 70 cm).
m Position the monitor to minimize glare and reflections on the screen from
overhead lights and windows. You may want to use a tiltable monitor stand.
The stand lets you set the monitor at the best angle for viewing, helping to
reduce or eliminate glare from lighting sources you can’t move.
Avoiding fatigue
m Change your seated position, stand up, or stretch whenever you start to feel
tired. Frequent short breaks are helpful in reducing fatigue.
m Use a light touch when typing or using a mouse and keep your hands and
fingers relaxed.
m Some computer users may develop discomfort in their hands, wrists, or
arms after intensive work without breaks. If you begin to develop chronic
pain or discomfort in your hands, wrists, or arms, consult a qualified health
specialist.
m Allow adequate workspace so that you can use your keyboard and mouse
comfortably. Place papers or other items so that you can view them easily
while using your computer. A document stand may make reading papers
more comfortable.
m Eye muscles must work harder to focus on nearby objects. Occasionally
focus your eyes on a distant object, and blink often while you work.
m Clean your screen regularly. Keeping the screen clean helps reduce
unwanted reflections.
