Getting Started
Selecting a place to work
Sit with your back straight so that your knees, hips, and
elbows form approximately 90-degree angles when you work.
Do not slump forward or lean back too far.
Lighting
Proper lighting can improve the readability of the display and
reduce eyestrain.
Position the display panel or external monitor so that sunlight
or bright indoor lighting does not reflect off the screen. Use
tinted windows or shades to reduce glare.
Avoid placing your computer in front of a bright light that
shines directly into your eyes.
If possible, use soft, indirect lighting in your computer work
area.
Arms and wrists
Avoid bending, arching, or twisting your wrists. Keep them in
a relaxed, neutral position while typing.
Exercise your hands, wrists, and arms to improve circulation.
Work habits
The key to avoiding discomfort or injury from strain is to vary
your activities. If possible, schedule a variety of tasks into your
working day. Finding ways to break up the routine can reduce
stress and improve your efficiency.
Take frequent, short breaks to change position, stretch your
muscles, and relieve your eyes. A break of two or three
minutes every half hour is more effective than a long break
after several hours.
Avoid performing repetitive activities for long periods.
Intersperse such activities with other tasks.
