CWT, I've experienced the same thing. I went from excellent vision my whole life to needing progressive tri-focals two years ago. I can't use my regular prescription to shoot. I did something similar as to what Swifty52 mentioned. I got shooting glasses with 1.5 magnification (I think). I can read reasonably well and I can shoot using them. If there is a better solution, I'm in. Right now, that's what works for me.
