Designed to completely eliminate glare from the waters surface which allows the angler to peer below the ripples to spot any carp that may be lying in the depths. Slimline, fashionable frames in either tortoiseshell with brown lenses or matt-black with grey lenses. The large lenses give great coverage Polarising lenses are perhaps the single most important item of tackle that you can own. They cut down glare to allow you to see your quarry as they move around, below surface. So, it was only natural that they would release a range of their own.
