·         If you bought glasses before, contact the store you got your glasses from and ask them for your PD (recommended).

·         Contact your optometrist for your PD (recommended).

·         Go to your local eyewear store or optometrist office and have them measure it for you. Most of them will charge only $5 for measuring your PD(recommended).

·         Measure the PD yourself, but not recommended.   

To measure your Pupillary Distance (PD) yourself:

Place a millimeter ruler on the bridge of your nose. You can do it yourself simply by looking in the mirror. If you need your glasses on to do this, you can draw dots on the lenses where your pupils are (using a magic marker or highlighter); then take the glasses off and measure the distance between them.

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).

 As a Guideline:

-      Your pupillary distance, or PD, is the distance between the centers of your pupils in millimeters (mm).

-      Remember, PD number is in millimeter. If your ruler has only inch, please convert inch into millimeter.

-      Most adults' PD's are between 54-70 mm

-      Most kids' PD's are between 41-55 mm. 

-      This measurement is necessary to ensure the correct positioning of your lenses within the frame you have chosen.

* You have several ways to obtain Pupil Distance, but we strongly recommend to get your PD measured by a professional. *
