How to measure your P.D (Pupillary Distance)
- On your prescription
PD value ranges between 57 mm to 65 mm with most common being 63 mm.
You may find your PD presented as 63/61. This means the Distance PD is 63 and the near PD is 61. When ordering single vision lenses, only the distance PD is required. For bifocals and progressives, please also provide the near PD.
Do it yourself!
- Step – 1
- Place a simple mm ruler on your nose so that the starting point of the ruler is exactly at your left or right eye pupil. Keep the scale straight.
- Step – 2
- Stand in front of a mirror or ask a friend to measure the distance between the pupils while you look straight ahead.
- Step – 3
- Repeat this three times for accuracy.
- Use an average
Your final option is simply to use an average PD measurement which is the least accurate method. Most adults have a PD distance ranging between 57-65mm. For single vision lenses, adults have an average pupillary distance of 62mm. In the event that you cannot obtain your own pupillary distance from your optician or measure it yourself, it's satisfactory to use this average PD measurement but please remember that this is the least accurate option.
For those requiring bifocal or progressive lenses, we strongly recommend you get this information directly from your optician. After you receive your PD from the optician, you may notice there are two different values. If you have the numbers '65/60' for example, the first PD is usually for distance vision and the second number is for near vision or reading.
