Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest,
or raising your sitting height to achieve maximum comfort. Observe the following tips:
refrain from staying too long in one fixed posture
avoid slouching forward and/or leaning backward
stand up and walk around regularly to remove the strain on your leg muscles

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.
For displays with glossy bezels the user should consider the placement of the display
as the bezel may cause disturbing reflections from surrounding light and bright
surfaces.
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, such as open windows, for extended periods
of time.
