How to measure your PD (Pupil Distance)

Knowing your pupil distance measurement will help us ensure that your lenses are fitted into the frame in the correct position. This measurement is vital as we need to be able to position the centre of each prescription lens directly in front of your pupils. Some Opticians will gladly give you this measurement if you request it but many will refuse, as they don't want their customers taking their sigh test prescription and buying glasses on the internet. We are now hearing increasingly about some high street opticians scare mongering customers into buying glasses in-store. This mainly due to the fact that many high street opticians have been accused of over-charging their customers for lenses and frames. They are becoming increasingly concerned that more and more people are buying their glasses online.  

How to take your own Pupil Distance measurement:










1. Stand directly in front of a non magnified mirror at a distance of around 7 inches

 2. Take your measuring rule and place it just above your lower eye lids. Or, if you prefer, you can place it on your forehead just above your upper lids.

 3. Close your right eye.

 4. Align the Zero mark on the ruler directly in the middle of your left eye pupil.

 5. Now close your left eye and open your right one.

 6. Look directly into the mirror and check which number on the ruler is in line with the centre of your pupil. This is your PD measurement!


You can repeat this process a couple of times just to ensure that you get a consistant result. Most mens pupil distance measurements are between 60mm to 65mm, for most women it is usually between 58mm to 63mm.
