NINES® Heat-Shielding Lens Technology

NINES lenses feature NIRTECH®, built to shield your eyes from sun heat and harsh glare. Standard sunglasses block UV, but NIRTECH® filters out near-infrared heat rays before they reach your eyes. This keeps your eyes cool, cuts eye strain, and stops that dry-eye feeling during long days in the sun. Core polarization wipes out blinding reflections from water and roads, giving you a clear, comfortable view.   

NIRTECH® also sharpens every detail in front of you. Color tuning separates muddy tones to boost depth perception, so trails, road bumps, and underwater structures pop into focus. Add in blue light filters that cut outdoor haze and a backside coating that stops reflections from your own face, and you get crisp vision built for any outdoor adventure.
