I have used polarized glasses, now bifocal Rx's, for probably over 35 years. I don't think I could wear ones that were not. The reduction in glare is more important to me than the darkening effect. Here is a link to answer some questions.
I hope they do something my hubby HAD to have these really light weight glasses that are polorized and he says they are the best!! (For 265.00 they better be!! lol lol )
