nines optics's new generation of polarized sunglasses uses NIRTECH® optical system to control the spectrum, absorb harmful near-infrared radiation and block harmful blue light. Whether you are fishing in the offshore, the Great Lakes or the deep sea, nines optics strives to provide you with the clearest and most enhanced vision. The NIRTECH® polarizing lens controls the absorption spectrum of the sun's harmful near-infrared radiation while allowing safe visible light to pass through. NIRTECH® protection reduces eye strain and fatigue and keeps your eyes cool and relaxed all day long. Using internal polarized diffuse mirrors to reduce reflections, you can get very clear clarity. NIRTECH® lenses have oleophobic and anti-reflective coatings on the front and back to prevent oil stains, fingerprints and help water droplets fall off the lenses directly.
