Monitor height
The maximum height of your viewing range is established by your horizontal
line of sight when you are comfortably and properly seated at your work
station.
A monitor that is set too high will cause you to tip or tilt your head
back to look up at the monitor. Over time, neck, shoulder, and upper back
pain may result. You may also notice dry eyes because there is a tendency
to blink less when looking up.
Monitor distance
Placing the monitor at a comfortable distance varies with each person.
In general, the closer you are to the monitor, the harder your eyes work
to keep the image in focus. You may experience eye fatigue, blurred vision,
or headaches if your monitor is placed too close. On the other hand, if
you lean forward to see the monitor, pull it closer to you.
If your monitor
is properly adjusted
10a. It is in front of you
and the top line of print is at or below your horizontal line of sight
or even lower if you wear bifocal, trifocal or progressive lenses.
10b. You can sit against
the back of the chair and read the monitor screen from a comfortable
distance, without experiencing eye fatigue, blurred vision, or headaches.
10c. The monitor screen
is free of glare.

Try these techniques
1. Periodically shift your view to something in the
background (behind the monitor). Give your eyes a chance to relax.
2. Periodically rest your eyes by closing them for
five seconds.
3. Adjust the monitor’s contrast and/or brightness
(light background, dark font).
4. Zoom in to increase the display percentage.
5. Blink!
