What is PD (Pupillary Distance)?
PD (Pupillary Distance) is the distance between the centers of your pupils, measured in millimeters (mm). It helps position your lenses correctly so you get clear, comfortable vision.
Why is PD important?
- Correct lens alignment
- Sharper, clearer vision
- Reduces eye strain and headaches
Types of PD
Single PD: One total number (example: 62 mm)
Dual PD: Separate measurements for each eye (example: 31 / 31)
How to measure PD at home
- Stand in front of a mirror
- Hold a ruler against your forehead
- Align zero with one pupil
- Measure to the center of the other pupil
You may also find your PD on a previous prescription or ask your optician.
