I'll add my two cents:
I've used variable focal length lenses for a number of years and love them,
but I recently had a discussion re them with an "expert" at Mass. Eye & Ear
Infirmiry (part of Mass. General Hospital).  He contends that bifocals are
better than variables because with variables one is constantly adjusting to
find the "right place" and the effort (of constantly adjusting) is too
tiring and makes one avoid reading.  I still stick by my variables, and it
isn't vanity (as that MD contends).
