Glare And Lighting - IBM NetVista A22p Quick Reference

Sitting in the same position for a long time can cause fatigue. A good chair can
make a big difference. The backrest and seat should adjust independently and
provide good support. The seat should have a curved front to relieve pressure
on the thighs. Adjust the seat so that your thighs are parallel to the floor and
your feet are either flat on the floor or on a footrest.
When using the keyboard, keep your forearms parallel to the floor and your
wrists in a neutral, comfortable position. Try to keep a light touch on the
keyboard and your hands and fingers relaxed. You can change the angle of the
keyboard for maximum comfort by adjusting the position of the keyboard feet.
Adjust the monitor so the top of the screen is at, or slightly below, eye level.
Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to
24 in.), and position it so you can view it without having to twist your body.
Also position other equipment you use regularly, such as the telephone or a
mouse, within easy reach.

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Even reflected light from shiny surfaces can
cause annoying reflections on your monitor screen. Place the monitor at right
angles to windows and other light sources, when possible. Reduce overhead
lighting, if necessary, by turning off lights or using lower wattage bulbs. If you
install the monitor near a window, use curtains or blinds to block the sunlight.
You might have to adjust the Brightness and Contrast controls on the monitor
as the room lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare
filter placed over the screen might be helpful. However, these filters might
affect the clarity of the image on the screen; try them only after you have
exhausted other methods of reducing glare.
