Pupillary distance (PD)

You'll need to know your PD if you want to order replacement lenses from Always Eyes. Don’t worry if your prescription doesn’t include your PD, we can definitely show you how to measure it your self. 

Measure PD yourself!!

  • Print our downloadable PD ruler. Download
  • Position the PD Ruler under your eyes - 0 should be under the center of your left pupil.
  • When the 0mm mark on the ruler is lined up correctly, the mark that lands in the center of the right pupil is your pupillary distance (PD).
  • Repeat a couple of times for accuracy and use an average for your final measurement.
