I am 65 and can shoot open barrel sights with plain lenses shooting glasses but, I have a piece of tape with a tiny hole I look through .It really clears up the sights .We shoot WW 2 military rifles out to 500 meters .Its slow shooting but it works . For my 03A3 and Garand and 1917 which have a peep hole at the rear ,I use a +1 power lenses which clears the blade to very sharp . Every ones eyes are different so experimenting and some compromise is needed .Almost every one I shoot with wears corrective lenses all the time and if I look through there scope or spotting scope I have to readjust for my eyes .Either my eyes are more normal than there's or I am the odd ball but I have won many matches and even recently .Arnie
