When you purchase a pair of eyeglasses, the manufacturer needs several measurements to ensure the frames and lenses will properly correct your vision. One of these measurements, pupillary distance, allows the manufacturer to ensure your lenses are centered on your pupils.
What Is Pupillary Distance?
Pupillary distance, also called interpupillary distance or PD, measures the distance between your pupils. You can read more information about pupillary distance in our recent blog post.
What Is the Best Way to Measure Pupillary Distance?
While you can visit an eye doctor to ask them to measure your pupillary distance, many clinics charge a fee to take this simple measurement.
Instead, you can measure the distance on your own at home by using a ruler or a pupillary distance app like PDCheck. We recommend using a pupillary distance app because it will usually provide a more accurate measurement.
