Your PD (Pupillary Distance) is the distance between the centers of your pupils, measured in millimeters. Accurate PD is essential when ordering eyeglasses online, as it ensures the optical center of each lens aligns perfectly with your eyes, preventing blurry vision and eye strain.

At See Clear Optical, we make it easy to measure your PD at your home visit.

Pupillary Distance (PD) tells optical labs where to position the center of each lens in your glasses. There are two types of PD measurements:
1. Single PD (Binocular PD) – the distance from the center of one pupil to the other.
2.Dual PD (Monocular PD) – the distance from the bridge of your nose to each pupil individually.

Your eye doctor can include your PD on your prescription, or you can measure it yourself at home using a ruler and a mirror.

You will need:

1. A millimeter ruler

2. A mirror

Steps:

Step 1. Stand about 20 cm (8 inches) from a mirror.

Step 2.Hold the ruler against your eyebrows.

Step 3. Close your right eye and align the ruler’s zero with your left pupil.

Step 4. Open your right eye and close your left eye.

Step 5. Mark the millimeter where your right pupil aligns. This number is your single PD.

Tip: Repeat 2-3 times to ensure accuracy.
