Hi Beaugrand, Hope you'r not minding my thoughts on your subject ;)
You"r wishing for a "little knob" on your glasses to accommodate " on the spot" perfect sight? Search and wish no further. Put ordinary and bifocals in the treasure chest, and switch to progressives. I'm a happy wearer of progressives and have been so for years. They do it all for me, far, near, midfield, sidefield whatever I wish for and all of that in just one frame. Last year I became a first time online buyer and ordered a pair of Kam Dhilon frameless glasses at Coastalcontacts. On top of the perfect lenses they put in the frame, the frame ls a-ma-zing! It can be over stretched, sit on, stand on, twisted, folded, etc etc. They are like a pair of eyes on sticks, and they do the trick for me. Because the frame is light, I forget I'm wearing glasses and so do others when I'm at "close encounters" if you get my drift..... Some people have problems adjusting to progressives, I think the secret is not choosing a frame with large lenses. Ah well, just pondering over the subject on a sunny morning sipping my coffee.
