i'm sure there are a lot of four-eyed nerds here so maybe someone will know the answer to this question. is it possible to get glasses resurfaced? i've had this pair for a long time and my prescription hasn't changed but they're covered in crap and very scratched. obviously these aren't thin lenses in the ideal sense but they're not coke bottle class either so i can't decide if changing the thickness by w/e ( a micrometer? ) would affect their focal lengths? actually do you guys think i could polish them myself with a soft dremel tool or something?
