When it comes to performance on the water no sailor or boater should ever settle for anything less then perfect polarizing performance. Sailors are pounded with tremendous levels of refracted light and visual noise on the water that requires both advanced lens and frame technologies. HD SPEX offers perfect polarization efficiency using a system of light management on the water. Our HD Diamond Vision polarizing lenses use our proprietary ColorTrast high definition color enhancing technology to provide optimal filtering of the harsh light and allow your eyes to focus and appreciate the crisp definition in the lenses. In addition to the distortion free lens delivery, HD Diamond Vision lenses offer 100% UV protection from the suns harmful rays. Some of our HD polarizing lenses are fit to frames that utilize our feather weight frame materials and weight just 1/2 an ounce. Both Plano and Prescription.
