How do I find my PD on my glasses prescription?

 How to Find Your Pupillary Distance (PD) on Your Glasses Prescription

Introduction

When ordering glasses, one crucial measurement often overlooked is the Pupillary Distance (PD). This measurement ensures your lenses align with your eyes for clear, comfortable vision. So, how do you find this on your glasses prescription? Let’s unravel this mystery.



What is Pupillary Distance (PD)?

Pupillary Distance is the measurement in millimeters between the centers of your pupils–essentially, the distance between your eyes. A correct PD measurement ensures that your eyes align with the optical center of your glasses lenses.

Finding Your PD on Your Prescription

Usually, your PD is included in your prescription. The two most common formats you might see are:

- A single number (e.g., PD: 62mm), which is a binocular PD–the total distance between your pupils.

- Two numbers (e.g., PD: 31/30), which is a monocular PD--the distance from the center of each pupil to the center of your face.

However, sometimes optometrists or ophthalmologists may not include your PD on your prescription. If that's the case, there are a few ways you can obtain it:

How to Measure Your PD at Home

- Ruler Method: Using a millimeter ruler, measure the distance between the centers of your pupils while looking straight ahead.

- Mirror Method: Stand 8 inches away from a mirror. Hold a ruler against your brow and close your right eye. Align the ruler's zero to your left pupil. Then close your left eye and open your right eye. The millimeter line that aligns with the center of your right pupil is your PD.
