Measure your PD

PD is the distance between your pupils, and it is used to help center your prescription in your frames. Your PD tells us where you look through the lens of your glasses and this number should be as accurate as possible. Your PD information is really important and helps us make sure your frames and prescription lenses are comfortable. To measure your own PD, follow the steps on our NYBK PD Measurement Guide.
