Thanks, guys and gals, lots of good suggestions. I figured will all of the old farts on here I would be tapping a lot of experience.
I might have some unique, or difficult requirements on this front, owing to the stuff I like to shoot and how I shoot it. I'm hoping I can wear one set of glasses and call it "good" for both looking through peep sights and adjusting them on the fly, which is kind of a requirement for competing in some of the matches I like to shoot.
Here are the sights I use in long range black powder matches. The vertical, or elevation scale, is essentially a vernier caliper. The horizontal, or windage scale, is essentially a barrel micrometer. I need to be able to adjust both at my spotter's command - "gimme two and a half minutes right", or "gimme half a minute up", and stuff like that.
Maybe my expectations (hopes) are a bit unrealistic, and there is no "one size fits all". I'm brand new at this, however, so I'll keep exploring the different possibilities.
As far as scopes (which I actually shoot very little), I've been able to adjust those ocular bells to my satisfaction, so I shoot with just safety glasses. I was able to make the open sights on the handguns work well today, so I'm happy with that. Monday I'll bring the recently finished Hawken out and try the glasses with its open sights. Funny, I didn't have any trouble right after I finished it, and that wasn't that long ago. I think peeps are going to be the challenge. Which is a shame, because that is what I shoot in my matches, and kind of a favorite for hunting as well. So, we'll see. I'll find something that works. I'm pretty motivated...
