Pupillary Distance (PD) is the distance, in millimeters, between the center of one pupil to the center of the other. The PD is needed to manufacture your eyeglasses because it determines the exact optical center of the lens, which is the point where you look through the lens. PD is especially important for manufacturing progressive lenses.
Once you have your PD, you can upload your photo to the Frame Fit tool and begin trying on glasses. The Frame Fit tool allows you to see exactly what the glasses look like on you and how well they fit the size and shape of your face. If you don't have your PD.
Single Vision lenses are the standard eyeglass prescription. These glasses are for one field of vision across the entire lens. Single vision glasses can be prescribed for distance vision, near-vision reading glasses, or computer-distance glasses. There are no lens height requirements for single vision prescriptions.
Progressive lenses includes three fields of vision, without lines. 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.
