Keith, I have the same problem. I use the Merit shooting eye (Brownells,Dixie,gun books) with a high degree of success. If you want to remain authenic then a piece of black tape with a small hole drilled in it and adjust with different size drills until you get a clear picture of the sights attached to your glasses. Also get another sight blank that will allow you to drill a peep sight in it will also work. Not much for hunting but you will certainly make the youngsters sweat. Tryit.
