What is Pupil Distance?

Posted by Kristina on

I have been receiving many inquires about what Pupil Distance (PD) measurement means when it comes to ordering prescription sunglasses. I decided to explain what PD measurement really is. PD measurement is a must for all prescription orders for it insures that your prescription lenses in your glasses are aligned properly in front of the eyes. It is the distance between your 2 pupils. Usually, you can call your doctor for that measurement if it is not written on your prescription. However, sometimes doctors don’t give out that information. In that case you can simply measure it yourself while you are looking straight at yourself in a mirror. PD is usually measured in millimeters. So, next time your order prescription sunglasses you do not have to wonder what PD measurement is that we will be asking for.
