I've had progressives and regular bi-focals for years and I still have trouble with progressives no matter how many times I get things adjusted or change lenses. I'm constantly taking my glasses off or moving them around on my nose. I've even tried bi-focal contacts. I'm used to it by now except when I'm at the shooting range when I'm trying to get perfect vision at a distant target and at my gun's site at about the same time. Other than that, I've just accepted things as they are. All in all, I'm glad I've still got great vision, even if I'm blind as a bat without my glasses. I have a couple friends losing their sight to macular degeneration, and I simply can't imagine what that must be like.
