Q: My PD is 61.5 and I wear size large frames. The PD recommended for the frames I've selected is 64 - 70. I have close set eyes. Please advise
A: Dear SONYA RICE,We are sorry for this, if you can not fill your PD value, we suggest you to choose other smaller frame.
Because we can not process this frame with your PD.
Every set of prescription lenses has an “optical center”, which should align with where you look through the lens. Pupillary distance is used to determine this and should be as accurate as possible.
If you fill the incorrect PD , you will feel dizzy or fuzzy when you wear the glasses.
