What is PD?
PD (Pupillary Distance) measures the distance between your pupils in millimeters.
This measurement helps center your lenses correctly for the best vision experience.
You may see:
- Single PD (example: 63)
- Dual PD (example: 31.5 / 31.5)
If your prescription does not include PD, contact your eye doctor or use a PD measurement app/tool.
