Measure my PD (Pupil Distance)
What is Pupillary Distance (PD)?
Pupil Distance (PD) is the distance between the pupils in millimetres. This measurement is needed when prescription lenses are being mounted in your optical frames. Most adult PD's are between 60-65mm. The average being 63mm.
No PD - Use our state-of-the-art PD tool to measure your PD. To do this, select the "Measure my PD" link in the prescription process.
2 PD's? - If you have 2 PD numbers this means that the PD for the right eye is different to the left eye. For Example, 31/33 means the right PD is 31mm and left PD is 33mm. If this is the case please click on "I have 2 PD number".
