Measure your InterPupillary and Working Distance for Loupes

Please use the guide below to determine your working distance and inter-pupillary distance for Flip-Up and Custom loupes.

100% Accuracy

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, from the comfort of your own home. Our methods have, so far, had a 100% success rate. And our 30 day trial period allows you to buy with confidence.

Working Distance

The working distance is defined as the distance from the loupes to the object being observed.
Equipment required: tape measure and chair

Step 1

Dental Working Distance
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.

Step 2

Maintaining your position in Step 1, hold a tape measure in one hand and draw it towards your eyes with the other hand.

Measure the distance between your eyes and the base of the tape measure as shown.

Inter-pupillary Distance

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 and a credit/store/loyalty card

Step 1

Hold a card under your nose so that it is touching your lips.

You can use any card as long as it's the same size as a standard credit card eg store card, loyalty card, gift card etc

Step 2

Ask a friend to take a photo of you at a distance of approximately 400mm (40cm) from your face.

Ensure that:

The flash is turned on in all photos
The photo is taken in a well lit location, and is of good quality
The card is parallel with the floor
The phone is at eye level

Repeat this step twice more so that you have a total of 3 photos.

Step 3

Send us your 3 photos using the form below.
Alternatively you can send your photos via iMessage or WhatsApp to +44 7842 639815.

We will then determine your inter-pupillary distance for you.
