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
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.
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.
