To measure your PD:
- Download the PD Measurement Instructions (PDF file) and open it in Adobe Reader.
- Print it at “No Scaling” or 100% scale setting.
- Fold the PD ruler along the dotted lines.
- By looking in the mirror or with the help of a friend, line up the ruler’s zero with your left pupil.
- Without moving your head or the ruler, mark the ruler where it lines up with your right pupil. This number is your PD.
- Enter your PD along with your prescription to complete your purchase.
