I first bought theblack rims and liked them so much I bought anotner pair to keep on by bike. The polarization is really great! A tip that may help some: since this style will fit precisely over the size glasses indicated in the description, I have found that the best way to put them on (at least for me) is to fit them over the sciript glasses first and them put them both on as a unit. Especially when worn under a helmet which can cause them to slip off the regular glasses.
