Bifocals don't have to look like bifocals. The progressive lens is a special kind of lens for bi focal reading glasses. There are no lines or half-moon “cutouts” in progressive lenses. Progressive lenses for bifocal reading glasses incorporate all corrections from distance to close-up.
Alternatively, the EZ-2-Vue Lens is a round segment for bifocal glasses blended into the distance part of the lens.
Progressive lenses look great and incorporate intermediate vision, e.g. the field of vision around a computer, better than segmented, lined bifocal eye glasses.
