Monitor position with single vision lenses for computer work (Computer single vision lens)

Your lenses for computer work include an optical power for a certain distance from the eyes to the monitor. Even if you do not know this viewing distance, you can easily find it out by shifting the monitor back and forth.

Monitor position with single vision lenses for computer work

Quick Start Guide

Adjust the height of the monitor to have a comfortable head position, not too high and not too low. You should always be able to look straight above the monitor beyond into the room. Adjust the tilt of the monitor so that you are looking at right angle to the screen surface: the more you look down, the more the monitor should be tilted backward.

Shift the monitor back and forth to reach clear vision on the screen. Many computer vision lenses have optimal vision at about 60-80 cm, but you better find out your individual optimum.

Detailed instruction: Monitor position with Computer Single Vision lenses

Before you start, you should adopt an ergonomic sitting posture (FIRST STEP).

Use the following steps to adjust the height of the monitor so that the head tilt is not strenuous but feels comfortable.. However, always make sure that your look can still go straight above the monitor if you try to look behind it:

  1. Tilt your head with eyes closed significantly up and down. Find with decreasing head movements your individually comfortable head tilt, which you please retain for the next step .
  2. With the retained comfortable head tilt and closed eyes, move now only the eyes up and down . Start with distinct tendencies of the eyes up and down movement and you will find the pleasant eye inclination.
  3. If you now open your eyes and look through the distance portion of your bifocals on the top third of your monitor, the height is correct . Otherwise, adjust the height position of the monitor accordingly.

Shift the monitor stepwise from a long viewing distance (about 100 cm) to a short viewing distance (about 50 cm) while you observe text characters on the screen with a size of about 3 mm that can easily be seen (a colleague may help you). Your computer vision glasses is usually set to a fixed distance (mostly between 60-80 cm). You will notice that the clarity of the text changes and you can find out at which monitor position the text appears most clearly and vision is comfortable:

  1. If clear vision is found very near (at about 50 cm), then your computer lenses may be too strong: computer work at such a short viewing distance is stressful for the ocular muscles in the long run. Check with an optician / optometrist whether these glasses are suitable for working at a computer work place.
  2. If clear vision is found near 100 cm, this is often relaxing for the ocular muscles. But long viewing distances require larger text characters of about 5 mm that cannot always be achieved.
  1. If, in this range, you do not reach clear vision at the monitor, as you know it from distance vision, then your computer lenses may not be appropriate. Then, you better have your vision tested.

When you have worked with the chosen position for some days, you may experience whether the monitor position is really optimal for you. If not, you may change the monitor position again. For the fine adjustment, you may tilt the monitor in a way so that you look perpendicularly onto the screen surface: the more you look down, the more the monitor has to be tilted.
