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 every 5-10 minutes for every 1 hour of viewing.
• 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.
