It's no big deal. Most of the time I wear the Progressives. I only switch when reading or watching tv.Oh crap. That would be an expensive accident. When I first had to have the reading glasses they gave me bi-focals which were a complete nightmare pretty much as you described with have to focus. I laterally had to stay dead still to see properly. So went to two glasses and I became irritated having to change from reading to far sight glasses so have not been wearing them. But eyesight has gotten worse. The left eye went from 0.5 to 1 (cant remember if I am supposed to put a minus there or not) anyway I figure I better start wearing them before the eyes get even worse and my eyes have to adjust to the new strength. Optometrist mentioned something about stigmatism in the one eye. They are a pain but things are definitly clearer. Hadn't realised how blurry it had become. I take my hat off to you coping with three.
