It sounds like you need the bifocal line moved lower. Or a dedicated pair of shooing glasses with the line way lower so you can still read with them if ya need to , like a scope adjustment or something.
For a try with contacts, monovision might be worth a looksee.
A close up lens in one eye & distance in the other. I used to wear bifocals(progressives) & was near the need for tri-focals. I got monovision Lasik's instead. The mono really confused my shotgun shooting at first, but I got used to it. Rifle shooting was fine from the start, & pistol shooting took some getting used to but not much.
