I can justify using my 45 and 25 year old frames with obsolete colors by remembering that I don't make my living shooting a shotgun. I do it for fun. Somehow, I made A class in International Skeet, AA or AAA in NSSA skeet, and carried an A class card in early day sporting clays, shooting maybe 300 birds a year. I shot them all at the same time and didn't realize that I wasn't supposed to be doing that. I guess my glasses weren't all that bad. A friend passed away not long ago and I have some of his more modern glasses. Unfortunately, I will have to have lenses made in my prescription. I guess I'll just do it.
