I have the progressive style now. Missed too many bottom steps of ladders with lined bifocals. The comment not stated is to make progressives work you will need to turn your head to get the clear focus,wide angle might help but you will find there is a sweet spot where it is the most clear.Sharing something that is being read you have to hold whatever it is because when the other person moves you have to move your head to keep up and have it clear.Driving in snow storms with progressives is almost too much visually because your peripheral vision will go bonkers with snow seemingly coming at you from all directions, I keep a pair of regular distance range glasses for that but seeing the dash is rough.With lined glasses if the area in the lower window is not moving they work the best but if you are in bleachers or stadium seating they will drive your eyes wild.Two pair only work if you are not doing close up work at the same time as needing far vision. If I am working on something too close to my head in a cramped spot the glasses have to come off because you can't get anything in focus.Size of the glass height and width dictates progressive strength.Too small and gets radical in the amount of movement it takes to get focused. Hopes this helps.
