i have been using progressive lens for over 15 yrs and love them.
i tried bi-focals but had trouble reading my cars speedo, \poor intermed. distance.
i prefer to use clip-on( not the flip up stuff) as a second leyer of protection for my lens.
i tried tranistions but on a sunny day driving my car the lens won't change, not enough sunlite can in the car to change them.
