Mid 50s, and have been wearing glasses for years (since grad school). I've done regular single-focus glasses, contact lenses, standard bifocals, and progressive lens bifocals. At this stage of life, I wear progressive lenses most of the time, and they work well enough at the range. But for hunting, I much prefer regular bifocals. The progressive lenses play havoc with your peripheral vision. I recently tried single focus (distance) glasses for hunting, but found I really need the close-in bifocal, too, or else I have to take off the glasses for close up work. Best compromise for the deer woods seems to be traditional bifocals, which keep my distance peripheral vision sharp, and still let me see to fill out the tag!
