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,
