If your eye doctor won't provide you your PD, don't worry! This short video tells you how you can easily measure your PD at home.
All you need is a friend or a mirror and a ruler. To download a printable ruler, click here.
An average range of adult PDs is between 54 and 74 mm. An average range of a child’s PD is between 43 and 58 mm.
Your PD should always be measured and not estimated. At a minimum the wrong PD can feel like something is wrong with your glasses, but it can also induce eye strain, fatigue, headaches and blurry vision.
If you have a high prescription and the wrong PD these symptoms can often be much worse.
If you are ordering a BiFocal or Progressive lens, even a couple of millimetres off can greatly affect how you see through your lenses
These are two different ways to measure your PD.
A SINGLE PD would be provided by one number and is the measurement of the center of one pupil to the center of the other.
A DUAL PD would be provided with two numbers and would appear and is the measurement of each pupil center to the center of the bridge of the nose, in millimetres.
Dual PD appears in the following format: "27/29".
