What do you mean by transition lenses? Do you mean like bifocals or the lenses that turn dark when you’re out in the sun? I’ve worn glasses since my early 20s and yeah, they’re paying to use with binoculars, but they’re not a big deal as far as using a rifle, scope or spotting scope. The key is getting the frames fit so that you are looking through the center of the lens in whatever position you were shooting. when I’m shooting prone in Competition, I have a set of Knoblocs, which are fully adjustable for the position of the lens, but I just wear my regular glasses when I’m in the deer stand and make it work.
