Enjoy winning style in Tifosi's Radius Fototec glasses. These lightweight shades boast Tifosi's exceptionally tough Grilamid frames and their Fototec lenses that automatically adjust to changing lighting conditions so that you can always see clearly. Plus, their impact-resistant, polycarbonate lenses and an open-frame design deliver an impressive field of view. You also get lens vents that ensure fog-free vision, while the hydrophilic rubber nose pads and adjustable temples grip even better when wet for a custom fit that stays put.
Tifosi's Fototec lenses use variable tint technology to rapidly adjust to changing light conditions for superior clarity and protection. In bright sun, photochromic particles embedded in the lens react to UV rays, darkening the optics so you'll never squint. With cloud cover, the particles return to their previous state to let in more light.
