What is my PD – Pupillary Distance
We require your pupil distance (PD) to ensure you will get the best optical vision from your sports eyewear. With the measurement we can ensure that the prescription lens optical centre is direct 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 make the measurement by yourself using one of the methods below.
How To Measure Pupillary Distance PD
With a ruler… to obtain a P.D. Measurement it’s best to ask a friend or member of the family to help you. Take a mm. rule and place it over the bridge of your nose with the 0 over the centre of your left pupil and take the measurement to the centre of the right pupil. If your eyes are very dark and the pupil cannot be seen clearly you can measure from the inner edge of the left iris to the outer edge of the right iris (see diagram below). Only one measurement is necessary any adjustments needed for reading or bifocal lenses will be made by us. To enter the value on our website take the total value, say 64mm and divide it by 2: 64/2 =32 and enter 32mm right eye and 32mm left eye. Take the measurement at least 3 times and achieve a measurement within 1 or 2mm
