Review on Polarized Cycling Sunglasses For Sports With TR90 Frame And 5 Lenses, UV400 Protection by Matthew Mrspeach

First a caveat. I've found no use for any but the basic three lenses of clear, dark, and amber. I use for mountain biking only. Perhaps, as a skier or boat person, I'd find the other two lenses useful.The lenses I do use have held up very well to 6 months of frequent riding. I take care of them, but still, they are in my gear bag when not in use. The case and protective sheath keep the lenses in good shape.The glasses are extremely light and comfortable. Even when I've sweated profusely, they have not slipped.Very easy to change the lenses.Very pleased with performance and even more pleased with the performance at such a reasonable price.
