PD (Pupillary Distance) is the distance between your two pupils in millime-ters. PD should be included on your prescription.

If there is no PD on your prescription, checking with your eye doctor is recom-mended, or measure your PD with PD Ruler

Download Printable PD Ruler

Which one should I choose, Single vision or Progressive?: Take a close look at your prescription from the Optometrist. If you don’t have Addition (ADD), please choose Single vision. If you have Addition (ADD), please choose Progressive.
Single Vision: Single Vision lenses are the standard eyeglass prescription. These glasses are for one field of vision across the entire lens. Correct one field of vision (near, intermediate, or distance).
Progressive: Progressive lenses correct near, intermediate, and distance in one lens. In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or mushroom. The top portion is used for distance vision, the middle portion (corridor) for mid-range vision, and the bottom portion for the near-vision or reading.
Non-prescription: Non-prescription lenses offer protection and style with no vision correction.
