Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on
how to reduce eyestrain.
Eyes
Rest your eyes frequently.
•
Give your eyes regular breaks by looking away from the monitor and
•
focusing on a distant point.
Blink frequently to keep your eyes from drying out.
•
Display
Keep your display clean.
•
Keep your head at a higher level than the top edge of the display so your
•
eyes point downward when looking at the middle of the display.
Adjust the display brightness and/or contrast to a comfortable level for
•
enhanced text readability and graphics clarity.
Eliminate glare and reflections by:
•
Placing your display in such a way that the side faces the window or
•
any light source.
Minimizing room light by using drapes, shades or blinds.
•
Using a task light.
•
Changing the display's viewing angle.
•
Using a glare-reduction filter.
•
Using a display visor, such as a piece of cardboard extended from the
•
display's top front edge.
Avoid adjusting your display to an awkward viewing angle.
•
Avoid looking at bright light sources, such as open windows, for extended
•
periods of time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing
and productive:
Take short breaks regularly and often.
•
Perform some stretching exercises.
•
Breathe fresh air as often as possible.
•
Exercise regularly and maintain a healthy body.
•
Warning! We do not recommend using the computer on a couch
or bed. If this is unavoidable, work for only short periods, take
breaks regularly, and do some stretching exercises.
