Jake, there is a term for that. Using one eye for near, the other for distance.
My former (now retired) opthamologist, and a good friend and avid shooter, told me in his experience a low percentage of his patients had success with that choice. It did work for some but the larger majority couldn't handle it. Yer choice but glasses are expensive to be experimenting with.
I did just that - made up a monofocal pair of shooting glasses. I've worn bifocals for many years, but lately just take off my glasses for closer-up work. Got my shooting eye focused out to work for both pistol and rifle sights - works great, & also good for meetings at work that involve table top distance notes and also across the room video or blackboard.
The term for that is monofocal. I have been using my monofocal contact lenses. I had my ophthalmologist use my right eye for near and the left for far. I found that my older contact lenses work fine for keeping the focus on the front sight. Especially good for my fowler as I shoot with both eyes open. My fight is in focus on the sight bead and my left eye is in focus on the target and it works just fine.
When older folks get their eyes surgically corrected, the doctor will make the adjustment for a monofocal vision. Bear in mind that sooner or later old eyes or presbyopia will catch up with us and we all will be wearing reading glasses.
