How to measure pupillary distance at home

Excited for your new Pair? We are too!

Pupillary distance (PD) is the distance (measured in millimeters) between the centers of the pupils in each eye. This measurement is used when preparing to make prescription glasses.

1

Find a metric ruler

And grab a friend so they can measure your pupillary distance in millimeters. Have them hold the ruler just under you eyes keeping the ruler exactly horizontal and line up the ruler’s (0) measurement with your right eye pupil (as show below).

2

Keep still

That means your head, eyes and ruler as still as possible. Have your friend read the millimeter line that lines up with the center of your left pupil. This number is your PD measurement.

3

Repeat

The above steps a couple times to ensure you get the same measurement. Let’s get this right for the best prescription possible.

4

Let us know

Write the PD number on your prescription and upload the picture at checkout or email the PD number with your order number to us at hello@paireyewear.com with the subject line Pupillary Distance
