• Avoid slouching forward and/or leaning backward.
• Stand up and walk around regularly to remove the strain on your leg 

muscles.

• Take short rests to relax your neck and shoulders.
• Avoid tensing your muscles or shrugging your shoulders.
• Install the external display, keyboard and mouse properly and within 

comfortable reach.

• If you view your monitor more than your documents, place the 

display at the center of your desk to minimize neck strain.

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,
