As you get older your eyes lose their ability to focus up close. Glasses and contacts can help but they can also inhibit your ability to see at distance. My solution for my most often carried handgun around the farm and in the woods was the XS Big Dot Sight. Initially it was a custom fit only option for the Ruger Single Seven (and Single Six) but now XS is offering a front sight for this revolver and you can easily install it at home.
