High Definition Video Solutions 4

As early as the 1830'S, Sir David Brewster noted in his Treatise on Optics, "The best position for microscopical observations is when the observer is lying horizontally on his back . . . . The worst of all positions is that in which we look downwards vertically."  Sitting or standing for hours on end, bent over a microscope eyepiece is not an activity for which the body is well adapted.  Poor posture and awkward positioning are the primary risk factors  that can affect full-time microscopists, who often experience pain or injury to the neck, wrists, back, shoulders, and arms.

Monitor Height and Position Guidelines

What height should my monitor be relative to my eyes?

There are several competing schools of thought on this issue, however, it is recommended that the top of the viewable screen of your monitor should be at the same approximate height as your eyes. Since most of the time you are focused in the middle of your monitor, you will be looking slightly downward at a 10° - 15° angle, on average. And the monitor should be slightly tilted back (about 10° - 15°) so that when you are looking at the center of the screen your line of sight is perpendicular to the surface of the screen. At the very most the bottom of the viewable area of your monitor should never be more than 25° - 30° below your line of sight.

How far away should my monitor be relative to my eyes?

This depends on an individuals visual capabilities, a good rule of thumb is you should be a minimum distance equal to the diagonal monitor width (i.e. for a 20" monitor, your eyes should be at least 20" away from the monitor).


1. Center Your Monitor For most workstations, the best position for your monitor is directly in front of you. Putting the monitor off-center (i.e., to the left or right of your body) can cause neck and shoulder pain due to twisting and awkward posture.

2. Sit Arms' Length Away Your monitor should be about arm's length away when you're sitting back in your chair. (Sitting too close or too far fromyour screen can cause eyestrain). If you have a large monitor - 20" or larger - you should sit slightly further back.

3. Position the top of your screen level with your eyes. The ideal viewing height is to have your eyes level with an imaginary line across the screen, about 2"-3" below the top of the monitor. This can be accomplished in one of two ways - either by either lowering your monitor or raising your chair. If your screen is too low, you'll find yourself tilting your head forward to view the monitor (a common cause of neck pain). If it's too high, you may have to tilt your head back, leading to neck and shoulder pain - and increasing the likelihood of glare from overhead lights (a common cause of headaches). Exception: If you use a large monitor (20" or larger), position your monitor so that the top of the viewing area is about 3" above eye level.

4. Tilt your monitor slightly upward. Tilt the screen so that the base is slightly closer to you than the top. This enables you to view the entire screen and the display more clearly. Tilting the monitor downward isn't recommended unless necessary to reduce the glare of overhead lights or if your monitor is too high and can't be adjusted.
