I needed a pair of glasses to use at the firing range. When you get to the age of not being able to focus on close up items, i.e. hard sights on a rifle, reading, yada yada yada….then something needs to be done. What I needed was a custom pair of “shooter glasses.” Adair Eyewear accomodated me just fine, as I tried more than a few optical shops that just could not do “custom” work. I can now sight in a rifle with reflex red dot, as well as the hard sights, I can read what I write down, and I can see perfectly fine in distance as well. All in one pair of glasses! Great job Adair!
