Re: Baby boomer eyes
Well, most good scopes have sufficient adjustment range of the ocular lens - the one closest to your eye - to allow shooting without glasses.
A relevant question, though, is what kind of shooting you do.
If you are a tactical rifle competitor or hunter, then surely you will want to have your glasses on when you are shooting.
If you are a benchrest or square range competitor, where all that will matter is your ability to observe the target through the scope, then you may not need your glasses.
However, I wear glasses with progressive lenses. In almost all shooting positions, I'm looking at the scope reticle through the part of the lens ground for distance vision, and there is no issue. I just focus the ocular lens so that the reticle is clear and sharp, and I have no other issues.
