Tough issue to deal with, I've struggled too, though my vision is just the opposite of yours.
My bifocal lenses exactly back-out my vision correction, I can take my glasses off and see just at well out to a few feet.
A switch I've made recently (2 yrs) is to Varilux brand lenses. You pay a slight premium, but the transition of the lens is so smooth that when I first put them on I started complaining that the glass company had forgot to provide me with progressive lenses.
It works great most days, though I have to admit that there are some days where I just seem to lose the recipe - I suspect that is just me and has nothing to do with my (purchased) equipment.
For shotgunning, I bought just a straight distance correction lens. I'm a fairly decent shotgun shot, if I ever have any strong awareness of barrel or bead I'm going to have a bad day.
