ROSSO Polarized HMC Both lenses are optical products made from high-quality material, designed for both functional and comfortable use. The Polarized technology blocks bright and harmful rays reflected from sunlight, providing a clearer and more comfortable viewing experience. HMC (Hard Multi-Coating Both) technology protects both surfaces of the lens from scratches, water, oil, and dust, facilitating cleaning and increasing the lens's longevity. ROSSO Polarized HMC Both lenses are ideal for outdoor conditions, especially for driving, at sea, or in snowy environments. There are grey, brown and green colors.
