Printable Pupillary Distance Ruler
Pupillary distance (PD) is the distance between the centres of your pupils. It’s an important measurement for getting the right fit for your glasses or contact lenses. You can get your PD measured by an optician, or you can use a printable PD ruler to measure it yourself.
To use a printable PD ruler, you’ll need a ruler and a mirror. First, print out the PD ruler. Then, hold the ruler up to your face so that the 0 mark is lined up with the centre of your left pupil. Close your left eye and look straight ahead with your right eye. Read the measurement on the ruler that is lined up with the centre of your right pupil.
Repeat the process with your left eye closed and your right eye open. The PD is the distance between the two measurements.
