Buying Glasses Online - How to measure your PD!

With lockdown taking up most of our year I needed to invest in some new glasses but did not have the luxury of being able to pop into my local optometrist. Shopping online is easy enough but the one issue I had with my personal prescription was the lace of PD listed on it!! I had no idea what mine would be and searched for any advice/info to help me measure it.  

Luckily  VisionDirect.com.au came to the rescue! I've been a huge fan of this store for years now and with some super easy steps, advice and even a detailed guide I'm able to measure my PD and order from them directly with absolute ease. 

How to measure your PD

Ready to buy new glasses online ? The first thing you’ll need is a copy of your up-to-date

prescription, but don’t forget that you’ll also need to supply your pupillary distance! Luckily

there are two easy ways to measure your PD so you can continue shopping with ease. Read

on to find out how.

What is Pupillary Distance?

Pupillary Distance (PD) is the distance between the pupils of your right and left eye. Measuring

pupillary distance is typically done by your optician so they can accurately fit your glasses. The

distance between the optical centres of your eyewear lenses should be the same as your interocular

distance to correct your vision.

What is the Average Pupillary Distance?

The average pupillary distance for most adults lies between 55 and 65mm, while the average pupillary

distance for children is usually between 42 and 54mm. However, for some people, pupillary distance

can vary outside these typical measurements.

How to measure your PD?

There are two easy ways to measure your PD- either by yourself with the help of a mirror or

with a friend and a ruler. Follow the steps in our infographic to measure your PD by a friend 

Measure your PD with a friend:

Step 1 – Hold a millimetre ruler up to the bridge of your nose.

Step 2 – Have a friend stand about an arm’s length away from you.

Step 3 – Close your right eye and ensure the ruler’s zero is aligned with your left pupil by asking a

friend.

Step 4 – Keeping the pupillary distance ruler still and look straight ahead, close your left eye and

open your right eye.

Step 5 – Have your friend read the number that aligns with the centre of your right pupil. This number

is your pupillary distance.

Step 6 – Repeat the process to ensure the most accurate result.
