How do your bifocal style reading glasses work?

Our bifocal readers have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses. (The power choices for the bifocal will be the power in the lower bifocal portion of the lens and the rest of the lens will be unmagnified.) Our bifocals do have a visible line between the two segments of the lens.
