This will be a controversial response. I'm 66 years old and like you I have a hard time seeing the sights and target. I've tried them all.....reading glasses of 1.0-1.25-1.5-1.75-2.0. Finally I went to my eye Dr. And had glasses made to the focal length to focus on the front sight.....real clear but you can't see the target. At 25 yards can't see the rings and on a good day I can bairly see the numbers. It's like you have to guess at where the X ring is. At 50 yards all you can see is the silhouette that's it. Yes....I know ...neck hold. I've tried it and don't like it. Yes I also know I'm in the minority. Any way I used these prescription glasses for a whole season and did pretty well with them. This winter when I moved inside to practice I started experimenting. I tried shooting with my everyday progressive style glasses and shot just as well ....bobbing my head up and down to find a happy medium of partial focus on the sights and the target. To make a long story short I went back to reading aviator style glasses of 1.25 strength. Wala the sights are not dead clear but good enough and I can see the target very well. I'm scoring much better. Can't believe it .......it's amazing. I know we have always been told........focus on the front sight but that may not be the best advice for older shooters that don't have The Eye of the Tiger. Try it you'll like it.
