P.D.= PUPIL DISTANCE
We require your pupil distance (PD) to ensure you will get the best optical vision from your eyewear. We use the measurement to ensure that the prescription lens optical centre is directly in line with each of your pupils. Most adult PD’s are between 60-65mm the average being 63mm. The best and most accurate measurement of your PD will come from an optician. If you don’t have a PD measurement on your prescription form, you can always contact your optician and ask them for it. If for any reason your optician is unwilling to provide the information. You can still get a PD using one of these options.
Option 1. Using a ruler:
For the best results, we recommend you ask a friend or member of the family. Don’t try to measure your PD yourself by looking into a mirror. Ideally, if you know an engineer or joiner, someone how is used to making accurate measurements would be perfect. If you are going to use a none professional make the measurement at least 3 times. If you are getting measurements within 1 or 2 millie meters you should be fine to use the value. Take a millie meter rule and place it over the bridge of your nose. With the 0 over the centre of your left pupil, take the measurement to the centre of the right pupil.
Option 2. Is to send to us a picture via Email or WhatsApp. We would require a headshot of the person who’s PD you would like us to measure. The person should be stood up straight and be holding a credit card or same size card under their nose touching the lip. The card is used to scale the size of the face, so the PD can be accurately measured, see image below:
Note: If you do use a credit card ensure the numbers are disguised or covered over for security reasons. Send the picture by email: email@example.com by WhatsApp: 0797 3333 046 If you have already placed an order and forgot to included the PD send the order number with the picture.
