What is Pupillary Distance (PD)
Hint: It's not the latest version of LOL or ROFL. PD stands for pupillary distance and it's the distance from the center of the pupil in one eye to the center of the pupil in the other. Don't worry, it sounds a lot more complicated than it really is.
Most prescriptions don't have PD included and often times, your doctor may not even have it on file. If you are one of the lucky ones, please provide your PD as part of your prescription.
