I'm sure this has been mentioned sometime on this site, but to ask again. I am a long-time beginning fly-fisherman (been doing it a long time, just not often enough to get good at it) and have always used a fairly cheap pair of polarized glasses. With Xmas coming up, does anyone have any suggetions for a reasonably priced pair of polarized glasses? Does a good pair of polarized make a big difference? Thanks for any help!
