MEASURING YOUR PUPILLARY DISTANCE
PD or Pupillary Distance measures the distance between the centers of your pupils and is used to center a prescription lens accurately in your frames. The distance is measured in millimeters between the centers of each pupil. Your eye doctor might use PD to check parts of your vision or eye function, but it's not usually important for managing your vision treatment. That's why it may not be included with your prescription even though you need it when you're ordering glasses. What can you do?
ASK YOUR DOCTORS OFFICE
Your doctor's office may provide you with your PD if they have it on file.
DO IT YOURSELF
No worries, you can measure your PD at home using this step-by-step guide.
