I have bifocals and it is the only way that I can see to shoot and I still have trouble. I have to kind of bob my head up and down to see the sights and then the target. Getting old sucks. I'm thinking about getting a pair of fixed distance shooting glasses from my optometrist. My problem is my eyes have different corrections so over the counter glasses are not an option. If you go for OTC type glasses be sure that it doesn't limit you to seeing your sights only (like reading glasses do).
