Your pupillary distance (PD) is the measurement in millimeters between your pupils. It allows us to locate the optical center of your lenses so the prescription is correctly placed in the glasses. If your doctor didn't include this measurement with your prescription, the following options are available to you:
- Measure your pupillary distance using our online PD tool.
- Call your doctor or optical provider to request your PD measurement.
- Visit an optical location to get your PD measured. This is either free or requires a small fee. Once you learn your PD, please email it to us at firstname.lastname@example.org with your order number.
