Note:
2)Here is a example to help you order your glasses from AMILLET Optical:
OD: Latin for Oculus Dexter, meaning the right eye.
OS: Latin for Oculus Sinister, meaning the left eye.
ADD (also NV-ADD): the Near Vision (NV) Reading ADDition correction on a multifocal Rx. Can be used for bifocalor progressive glasses, or for single-vision reading or computer (intermediate) vision glasses.
PD (Pupillary Distance): the PD is the measurement of the distance between your pupils. This is needed for the manufacturer of the eyeglasses to know where to place the optical center on each lens, so you can see well with the glasses.
How to choose the suitable lens for your rx

It usually take 5-8 days to make bifocal or progressive lenses from factory.
