PD Measurement
-
Pupillary Distance (PD) or interpupillary distance is the distance between the centers of the pupils in each eye.
-
The industry standard is to measure in millimeters.
-
This measurement is used when preparing to make prescription glasses.
How do I measure my Pupillary Distance (PD)?
- Help from a friend:
- Place a millimeter ruler on the bridge of your nose.
- Have a friend face you about arms length away.
- Have your friend measure the distance between the center of your pupils (the black dots in the middle of your eyes).
- Measure Yourself:
- Look in the mirror while wearing glasses.
- Draw dots on the lenses where your pupils are (using a non-permanent magic marker or highlighter)
- Take the glasses off and measure the distance between the dots.
- Optometrist or Optician:
- Most eye doctors and/or opticians will take the measurement for you in exchange for a very small service fee.
- Guideline:
- Most Adults measure between 55mm -65mm.
- Most Children measure between 42mm - 54mm.
Now you know your PD Measurement!
A valid prescription with PD Measurement is required to order your new prescription glasses.
