Dear Jeff,
Concerning your question about monitor height ....
It is indeed important to maintain as close to neutral cervical posture
as possible, thus the basis for your point. However, the natural resting
point of the eyes is 0-10 degrees below horizontal. Try it for yourself
- look straight ahead, then allow your eyes to fall to the natural
resting point.
Therefore based upon a viewing distance of 25 - 30 inches for a 14 inch
monitor, and assuming that the operator's vision is corrected to 20/20
(or 6/6 if you are familiar with the metric system), 0 degrees is the top
of the screen (not the top of the monitor) and -10 degrees is the center
I hope that this information answers your question.
