It REALLY helps when you have an eye doctor (Opthi...what ever the hell they call it) who is a shooter. When I described my problem, he immediately knew what to do.

I use bi-focals that work really well for seeing as well as shooting, Close range reading requires extra lenses, but sights are not a problem. I discovered my sight problem when I ran out of adjustment in my scopes. Damned....you think that was a problem??

Just recently....in my back yard (I have a 100 yard range in my back yard).....I found I could clear 10 beer cans quicker than my younger cousin with open sights. I can't see the righting on the cans like I used to but I can still see the cans just fine (30 years younger doesn't make enough difference).

At 100 yards...minute of beer can is good enough..... and it's good enough on game too.
