No, it's one lens width plus the entire bridge width. If you want your pupils to center in the lenses, then between them you'll have half of one lens, the bridge, and half of the other lens. > If so, the lens > width of the frame I've (mostly) decided upon at Zenni is 50mm + the > bridge 18mm / 2 = 59mm.

If your PD is around 60, than you should be looking for frames with (for instance) 18mm bridge and 42mm lenses, or thereabouts. That will keep the edge thickness of your lenses to a minimum all the way around. > For whatever it's worth, I think I just have a little larger face > overall than some.

Look for frames that extend past the outer edges of the lenses before bending back towards the temples. That increases the total width of the frames without moving the lens centers farther apart.
