The polarized film for Polarized Lenses is applied to the front surface of the lens. When the lens is beveled to fit into the frame groove, the front bevel may strip away some of the polarization film revealing the clear part of the lens. This may appear like a gap, but is only the film being stripped away. Although this issue is usually reduced by moving the bevel more to the back of the lens, this is not always guaranteed, especially for thicker edged lenses.
