I have shot long range out to 1200 yards for several years. Consider myself fairly decent shooter. I don't compete but love to shoot. Am going to be 53 this summer. About 3 years ago had to get glasses. Went out and shot on private farm I use today and was so disappointed. In matter of few months I struggled GREATLY to see through scope. No matter what I tried nothing worked. Tried glasses (bifocals) and can't make that work since hard to get eyes straight behind scope. And won't work well now without glasses. ANY ideas or have I hit an age and time sell out? By the way my optics are tangent theta so that's not an excuse.
