No offense taken at all. I'm a young 67, need my cheaters for up close but can still see far good.Old age? Only Kidding! At 77 I understand. I had to resort to a circle of tape with a hole punched in it. Worked great .
I put a ghost ring sight on my deerhunter rifle, what a difference it made for me. The iron sights on my Tennessee rifle are difficult to focus on at distance.
