I’m not as old as you are, but about 5 years ago I started to need readers/cheaters to read things at arms length and closer. I still see fine at distance.
The same applies to my front sight which appears blurry. If I wear my cheaters, the front sight is in focus but then the target becomes blurry. After experimenting with different glasses I found a pair that is about 1/2 the power of my cheaters, which was a good balance between being able to see my front sight clearly and not make everything beyond arms length blurry. This has worked well for me to shoot iron sighted guns in competition, and having a narrow front sight (.100” wide) with a fiber optic helps me pick up the sight quickly and not obscure too much of the target as I’m not a fan of the 6 o’clock hold.
But seeing as I am unlikely to wear those special glasses all the time, for my EDC gun I switched to a RMR with 6 MOA dot. That’s been working well for me since most of the time I shoot “target focused” and press the trigger when the dot is lined up.
