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!
