Today, we’re going to teach you a trick to ensure your new glasses fit perfectly: knowing your pupillary distance (PD).
So, what exactly is pupillary distance?
PD is the distance between the center of your right pupil and the center of your left pupil (in millimeters). This measurement is essential when getting new glasses because it ensures you’re looking through the correct part of the lens.
How do I know my pupillary distance?
If you’re visiting any of our optical stores, no worries! Our professionals will measure your PD for you. But if you’re planning to make an online purchase and need to know your PD, here are some tips to measure it easily at home.
Tips for Measuring Your Pupillary Distance at Home
Before you start: Ask someone to help you measure with a ruler. Measure the distance between your pupils and divide it by two to calculate the PD for each eye.
Rounding off: If dividing to find the PD for each eye doesn’t give you a round number, don’t stress! It happens more often than you think. Simply round to the nearest whole number, and we’ll handle the rest.
Typical range: Your PD will typically range between 58 and 68 millimeters. If your measurement is different, or if you have a prescription higher than 6 diopters, give us a call.h
Frequently ask questions
Can I take my PD at home?

Is it necessary for any type of lenses?
Primarily for prescription glasses and sunglasses. If you wear progressive lenses, we recommend visiting our optician: we need to measure your pupil height with the frames on to ensure comfort and optimal vision.
What if my prescription is incorrect on my lenses?
It can cause eye strain, blurred vision, and discomfort in the head or temples.
Is it a free in-store service for customers?
Yes. Measuring your interpupillary distance at any of our opticians is free for customers. Our optician accurately records your PD, ensuring that future orders for lenses or glasses are precise and comfortable.
