Im at the point in my life where it's hard for me to see the sights on some of my pistols. Last years eye exam. The doc said i could use what he called a small prescription. I opted out, Because i can still see well driving and spotting game and stuff off in the distance. And i could still see my sights and target. Now the sights are blurring. I do use reading glasses. 2.50 strength. How do those who wear glasses see the sights and the target? I would guess bifocals would not work? Im ok with that since i have reading glasses. Thanks Al.
