Your PD Measurement

Your PD measurement is the distance between the centres of your pupils and is required to ensure you get the best possible vision from your new glasses. Measured in millimetres (mm) your pd helps us make sure the optical centre of the lens is directly in line with the centre of your pupils. Most adults will have a PD measurement of between 60-70mm.

PD Measurement (supplied by optician in mm)

Please note: your PD measurement may be written as a single number i.e 66 or as two values i.e R:33/L:33. Please supply exactly as written on your prescription

Help! What’s my PD?

All opticians are required to take your PD measurement if they have made glasses for you, but many won’t write it on your prescription. If your optician is unwilling to provide you with the information, it is possible to get a family member or friend to do it for you. For information on measuring your PD, click here.
