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,
