Please use the guide below to determine your working distance and inter-pupillary distance for your loupes
Traditional companies require a fitting appointment to calculate your measurements, which increases the overall cost of loupes. We have worked with opticians to develop technology that allows you to take these measurements digitally, from the comfort of your own home, with a high degree of accuracy. Our 30 day trial period allows you to purchase your loupes with complete confidence.
The working distance is defined as the distance from the loupes to the object being observed.
Equipment required: tape measure and chair
Sit in an adjustable chair, as if you were working on a patient. It is important to sit in an ideal posture, as this is the posture you will be using when wearing the loupes:
- Feet flat on the floor
- Thighs parallel to the floor
- Straight back
- Arms at a 90 degree angle
- Elbows close to the body
All Other Working Distances
If you are not a dentist, please sit or stand in your usual working position, maintaining a comfortable posture and straight back. Then proceed to step 2 to measure your working distance.
Measure the distance between your eyes and the base of the tape measure as shown.
This measurement is only required for Custom TTL Loupes and Custom TTL HD Loupes.
The inter-pupillary distance is defined as the distance between the two pupils of your eyes.
Equipment required: camera, tape measure and a ruler
We use technology to analyse your photos that calculates your inter-pupillary distance within 0.1mm.
Hold a ruler above your eyes, making sure it is parallel with the floor and touching the centre of your forehead.
Ask a friend to take a photo of you at a distance away from your face that is your working distance (measured above). Use a tape measure whilst taking the photo to ensure this distance is correct.
Repeat this step twice more so that you have a total of 3 photos.
