These glasses are not polarized and do not have any indication that they protect for UVA/UVB. They do provide some shade from the sun, but not anywhere near as much as some polarized sport glasses I have (that were, to be fair, about 8x the price). They look cool though, and are better than wearing no sunglasses at all. If you're looking for a nice looking pair of shades and don't need serious sun blocking, these are for you.
