My issue is not with the glasses per se but with the description.  These are advertised as polarized and I'm surprised none of the other reviews have mentioned this (unless they received different glasses). It just so happens that I ordered 2 pair of these. You can tell a lens is polarized when you hold two up in front of your face and rotate one so that they are at angles to each other. You can watch the image get darker until it totally blacks out. These absolutely do not do that. Be careful with this order if you really care about the polarization
