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 for extended periods of time.

Developing good work habits

The following work habits make 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.

Note: For more information, please refer to "Regulations and 
safety notices" on page 55.
