To find your pupilary distance (P.D.) take an ordinary ruler and rest it on the top of your nose and measure the distance, in millimetres, between the centres of your two pupils (black spots in the centre of your eye). The number should be somewhere between 40-90 millimetres.Most peoples PD is 63. Enter the P.D on the prescription page. To see how wide your face is, just look in the mirror with an ordinary ruler resting on the top of your nose and measure the total width of your face

The Pupillary Distance (PD) is the distance between your pupils (centre of your eyes). It ensures that the lenses are accurately positioned in the frame. Please ask your optometrist to measure your PD when you obtain your prescription. Alternatively, you may choose to use the average PD provided by our optical dispensers which is 65mm for distance vision and 62mm for reading vision. See similar questions...

This is the distance between the centre of your pupils. The measurement helps us to correctly position the lens within the frame. We recommend that you ask your optician to write this measurement on your prescription.If however you do not have this measurement, we will fill the order using an average Pupillary Distance of 63mm for a man and 60 for a woman See similar questions...

Please ask your optician to measure your PD when you have a sight test. The optician who supplied your last pair of glasses will also have your PD measurement. Alternatively you can send in an old pair of glasses to us from which we can measure your PD. See similar questions...

PD, or pupillary distance, is the distance from the center of the pupil (the black spot in the eye) of one eye to the other. This measurement refines the positioning of your lenses within the frame you have chosen. It can be provided in minutes by your optician or doctor, and so we recommend that you ask for it when you have your vision checked. Alternatively, you may ask someone to measure it for you but advise them to be at about an arm's length away from you. See similar questions...

Inter-pupillary distance (PD) is the distance from the center of the pupil in one eye to the center of the pupil in the other eye. A PD measurement ensures that the center of the lenses line up with the center of your pupil. Before your prescription lenses are cut into the shape of your frame, the pupillary distance needs to be measured. This measurement is then used so that the optical center of each lens can be lined up with your pupils in order to give optimal visual clarity. See similar questions...

The distance from the centre of one pupil (black spot in the middle of your eye) to the centre of your other pupil is your pupilary distance. Having a correct measurement for this improves the positioning of the lenses within your chosen frames. See similar questions...

Your pupilary distance (PD) is the distance between the centres (pupils) of each of your eyes, measured in millimetres. Your PD measurement is used when we take a lens with your prescription and customise it to both fit your frame and you. To be effective, a lens must be cut so the centre is directly in front of your pupil. Without your PD it is difficult to work out where that point is for you. See similar questions...

No, we must have a PD, and it should be a number in millimeters normally between 54 to 70 and for kids between 41 to 55. Contact us if your adult PD is below 50 or above 70. Please remember prescription goggles / prescription sunglasses / RX adapters orders will NOT be processed without PD. See similar questions...

Some prescriptions do contain more than one pupil distance. In some cases two PD is due to different measures for the right eye (OD PD) and the left eye (OS PD). Another reason for more than one pupil distance is the need to correct both distance and near vision. In this case your prescription will state either PD near or PD dist. Please contact your optician and decide whether you require progressive/bifocals or single vision eyewear. See similar questions...

Pupillary distance (PD) is the distance between the center of your right pupil (the black circle that contracts and expands depending upon available light) and the center of your left pupil. This measurement is necessary to precisely center the lenses in a specific frame. See similar questions...

If your optician or optometrist provided two numbers, they are either distance and reading pupillary distance (PD), or right (OD) and left (OS) PD. Let’s say your numbers are 63 and 60. The former, which is always higher, is for distance, and the latter, which is always lower, is for near-vision reading only. Another example: If your numbers are 33.5/32.5, your PD was taken monocularly, meaning one eye at a time. See similar questions...

It is the distance from one pupil to the other. You can get your PD from the last place you ordered glasses. See similar questions...

PD is the distance from the centre of one pupil to the centre the other (the pupil is the black spot in the middle of your eye).
