Q: The PD box when entering my rx is not allowing any number below 68. Trying this site for the first time is massively frustrating. If the glasses selected cannot support PD of 60, yet are in the exact range of measurements for my face, why the f doesn’t it say that somewhere instead of not allowing me to enter my prescription????? Please go ahead and try it. I’m sure you will love the process.
A: Dear customer,
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.
