I've worn glasses since I was in the 4th grade. Now, I have to wear bifocals. I've had to make a few adjustments here and there, but whether shooting 3-D or hunting, I have no issues with them. This past year, my darling bride of 33 years insisted that I become a little more "stylish" in eyeglass frame selection. So, I got some that have holes drilled through the lens and the bridge and eyepiece are mounted with screws through these holes in the lens. BIG MISTAKE. The screw in the right lens lines up perfectly with the eye when I'm trying to shoot. I can't pick a spot on the target because the spot is covered with the screw that holds the bridge in place.
Point is, be careful of your frame selection and try them on and tilt your head to pretend you are shooting. If anything interferes with your vision, don't get them.
