Pupillary Distance Measurement

Pupillary distance (PD)

You'll need to know your PD if you want to order replacement lenses from Always Eyes. Don’t worry if your prescription doesn’t include your PD, we can definitely show you how to measure it your self. 


Measure PD yourself!!

1. Print our downloadable PD ruler. 

2. Place the ruler directly over the center of your right pupil so that the ruler is horizontal. Place against forehead for added stability. Stand in front of a mirror, or ask someone else to measure for you.

3. While looking straight ahead, measure the distance from the center of your right pupil to the center of your left pupil.

4.Repeat a couple of times for accuracy and use an average for your final measurement.
