Apparently the DWP lenses are manufacturer by Oakley/Luxottica. So the quality of lenses should be similiar to the OEM lense. Its just a shame about the brown tint as the DWP do look super bling bling but I don't know if I can put up with the tint. Thanks for the information.No worries, although I have to say that the Prizm lenses make the greens much greener compared to mu non-prizm oem lenses, in case you're interested with that.
