i find myself in a unique position. i have always used prescription glasses, clear and dark, when shooting cause i couldn't see sites/targets w/out em. had lasik done and can actually see the sites and target bare eyed. unbelieveable! am now in a position to use shooters glasses like normal people and need advice. i like the dark lens ones, but since the sites are dark AND the lenses are too, won't that make it harder to see the sites on a non sunny day? the prescription ones i wore b4 were smoke, not dark. but i see all sorts of shooting glasses for sale that look dark as all hell. so how do you see the sites on a cloudy day? will i have to buy 3-4 diff. shades of tint? THANKS
