Billy,
When I was getting my eyes examined for glasses, tri focals, the last time, they asked if I had any special needs or hobbies.
I said that I work on computers a lot and I also shoot handguns. They asked how far away my monitor was and to show them what I needed to focus on when shooting.
No, I didn't pull out my CCW, but I did assume a stance and told them, "about 4" in front of my right hand".
They adjusted the center field on my tri focals to that distance and now the front sight is nice and sharp. Made a big difference.
Talk to the people who are writing your prescription, they can help.
