THE PD IS THE DISTANCE BETWEEN THE CENTRES OF YOUR PUPILS.
Pupillary Distance (PD) is the distance measured in millimetres between the centres of the pupils of the eyes. We need this measurement to ensure that your prescription glasses will fit you correctly and that you're looking through the ideal spot of the lenses.
In the UK the PD won’t necessarily be included in your prescription as it’s considered part of the dispensing service.
The easier way to find out your PD is to or use an online measuring app or to ask your optician to measure it during your eye-test. This is normally done with a small ruler called a "PD stick" or with a pupillometer, a machine calibrated to help achieving a more accurate measurement necessary for bifocal and varifocal prescriptions.
You can also measure your PD at home with just a mirror and a millimetre ruler, just follow the simple steps below:
- Stand in front of a mirror with your shoulders as straight and centred as possible.
- Align the 0 mark of the ruler with the centre of your right pupil and make sure that the ruler is horizontal. Place it against your forehead on your brow-line for added stability.
- While looking straight ahead, measure the distance from the center of your right pupil to the center of your left pupil.
- Repeat the steps a few times for accuracy.
