To get it right, I finally went to a local optical shop and had them custom made. Ended up with tinted, safety, shatterproof prescription glasses that work oh so good and didn't cost an arm and a leg either.
You do need to be careful, however, that they know these are for pistol shooting rather than, say, trap shooting so they can get to focal point in the right place...for pistols, out about where the front sight on a long barrel revolver when held at arms length. Some optical techs are knowledgeable but to others, shooting is shooting and they do not dirrerentiate between pistols, shotguns and 1000 yard rifle shooters.
At age 70 with aging eyes, this investment has put the fun back into shooting!!!
