WD Measurement

Working Distance

Optimal view and complete work ergonomics start with accurate measurement. The working distance is the point where the optics are sharpest and your posture is most natural. To ensure the complete fit of your individual loop, We ask that you make the next measurement in preparation for the appointment.

This is how you do the preparation and measurement correctly:

1. Take a position: Sit or stand in the position where you do your job normally. If you wear glasses at work, keep them in your head.

2. Take the instruments: Simulate the actual work situation with the instruments in your hand. This ensures that shoulders and elbows settle in the natural corner.

3. Use your assistant: Ask a colleague to measure the distance in millimetres from the surface of the eye (or from the surface of your glasses) directly to the target.

4. Confirm posture: Keep your back straight and neck in neutral position. Don't reach for the tape, let the optics bring the object to your eyes.

5. Select the comfort range: Try moving a few inches forward and back. Write down the distance where the position feels the most free.

Expert tip: If you are between two measures, we recommend choosing a distance of 1-2 cm. This helps to keep the back straight and prevents bending towards the patient.

Why is this preparation important?

Each pair of loops is manufactured individually (TTL - Through-They-Lens) according to the working distance and the pupil distance (PD) indicated. By doing this preconditioning, we ensure that:

• In the event of a settlement, we'll get straight to fine-tuning.

• The field of vision is wide and sharp up to the edges, just as you do.

• The neck-shoulder load will decrease and your working comfort will be maximised.

• Our expert will verify and check the measured distance with you during the arrangement.
