I asked an optometrist one time. The optical center/focal point/whatever of the glasses is in an average place in your glasses lens. I have forgotten what he called it. Anyway, when you are measured for glasses they do they thing with the little ruler and see how far apart your pupils are right? Same thing just a different dimension. See if the optometrist can raise the optical center up in your field of view. This might mean a pair of "shooting only" glasses, but it might help. The biggest thing that I notice after screwing around with Leupold, Bushnell, and Simmons and all of the flavors of multi-coatings is that you need the antiglare or antireflective coating on your glasses. The newer version isn't so smudge sensitive either. I had the old coating and HATED it for the smudging. So I opted not to get the coating. Big mistake. Bright sunlight means reflections between the scope lens (on cheap scopes) and my glasses and between my glasses and my eye.
