Yes! Welcome to the fuzzy world of presbyopia...a 'now that you're in your 40s' thing. I've been wearing lineless bi (actually there's a sliver of a third magnification) focals for years and never had any trouble with using any kind of camera other than to sometimes have to take the glasses off entirely to see the entire screen on my P67.

The real PITA is trying to play tennis. The ball comes at you in your upper distance portion and then you drop your gaze to follow the ball into your racket when...$#%@$^^^!!!!....the focus changes completely to the close-up part....where? what ball? d'jou hit a ball? Grrrrrrrr....
