This is a real premium set of safety glasses. They are quite comfy, and polarization works very well. It cuts haze and flare (on water, glass, snow). Enough light passes through the lenses when you are indoors (but not in complete darkness).
A previous reviewer complained about pricing discrepancy with this pair.
Hello! There are two DIFFERENT types of these glasses that feature the same frame and the same COLOR of lenses: plain blue and POLARIZED blue. Hence the price difference.
