I had cataract surgery several years ago. My vision is 20/20...but the target is always more than 20' away. I have tried so many different configurations of glasses, it's almost mind boggling. I know that when I can see the target and the sights at the same time, I can hit what I'm aiming at, but that doesn't always happen. I ran across a posting about pinhole glasses yesterday. I made myself a pair out of an old, scratched pair of wrap around riding glasses. Today I went to the range with my CVA Hawken. I know this rifle is capable of really tight groups, but only when I do my part. The pictures tell the story. The two strays are from minie' balls the red dots are from using my conventional glasses, and the one hole group...well that's the thing, then....shooting at 50 yds from a rest. It was all about the glasses, today :grin: https://goo.gl/photos/NPdTyMR3MGkBvQxK9 The second hole in the lens is for pistol shooting!
