List, I wear progressive focus lenses (just got a new pair Friday). Over the years, I've also had lined and never had any problem switching back and forth. Lucky, I guess. For a number of years, until the prescription got too out of date, I had what they call "Double D" lenses which I used for mostly for regulation. They have a D shaped bifocal area below _and_ above centerline. I REALLY loved them when I was doing grand dampers. As I understand, plumbers and electricians use them a lot because of a lot of overhead, but close, work. I had them in a HARD clamshell case in my regulation toolkit.
