most everyone gets cataracts sooner than later. that's the prime issue seeing gun sights. getting that fixed these dayze is easy and medicare and most plans pay for it. i had mine done in may of this year and i shudda got it done a decade or so ago, because after the first eye was done it was like seeing a whole new world, the difference was that great. the op is a piece of cake and my 72yo eyeball lenses got swapped out for a pair of implanted acrylics that are perfectly good for life. amazing difference. there is no need to put up with the blurriness of cataracts, not in this millennium. don't wait, no need to complain about gun sight issues, y'all have had a cure that's been around for years.
