A Guide to Measuring Pupillary Distance at Home for Accurate Prescription Eyewear

We understand that getting the perfect eyewear can be both essential and convenient. That's why we're here to educate you on how to measure your pupillary distance (PD) from the comfort of your own home. Armed with this knowledge, you can get an approximation of your prescription without leaving your house, making the eyewear shopping process simpler and more accessible.


What is Pupillary Distance (PD)?

Pupillary distance (PD) is the distance between the centers of your pupils, measured in millimeters. This measurement is crucial for crafting lenses that align perfectly with your eyes, ensuring clear vision and maximum comfort. Although a professional optometrist can provide an accurate measurement during an eye exam, you can also approximate your PD at home.

Why Measuring PD at Home is Important:

  1. Convenience: Measuring your PD at home saves time and eliminates the need for multiple trips to the optometrist's office.
  2. Online Shopping: With your PD in hand, you can confidently order prescription eyewear online.
  3. Privacy: If you prefer the comfort of your home, measuring your PD lets you enjoy privacy during the process.
  4. Cost-Effective: Reducing the number of visits to an optometrist can save you money.

What You'll Need:

  • A ruler or PD measuring tool
  • A mirror
  • A well-lit room


  1. Stand or sit in a well-lit room and hold the ruler or PD measuring tool up to your face.
  2. Look into a mirror, ensuring your face is evenly lit, and your eyes are at the same level. Keep your head straight and look straight ahead.
  3. With the ruler or PD measuring tool in your hand, align it with the center of your right pupil. Ensure it is parallel to the floor.
  4. While keeping your head steady, have a friend or use a digital camera to capture your image while holding the ruler. Make sure the photo is taken at eye level.
  5. Repeat the process for the left eye, aligning the ruler with the center of your left pupil.
  6. Measure the distance between the two marks on the ruler in millimeters. This is your pupillary distance.
