When outdoor light conditions change, the Brown Polarized lenses of the Radius Sunglasses from Tifosi change, too - automatically darkening in brighter light to ease eye strain and allow you to enjoy your ride, run or other outdoor adventure. The Radius' Fototec lenses adjust from 28.7% visible light transmission in shade or cloudy weather to 9.4% in bright sunshine.
The scratch- and chemical-resistant, shatterproof polycarbonate lenses offer full protection from harmful UVA and UVB rays, and the vented design promotes air circulation and prevents fogging. The aerodynamic crystal brown frames are made of lightweight, durable Grilamid TR-90 nylon material, and feature adjustable, hydrophilic ear and nose pieces for a snug, custom fit. A hard zippered case and a soft microfiber bag are included. Note: Fototec lenses do not transition when inside vehicles because the UV protection in the windshield prevents the process.
Fototec technology quickly adjusts lens darkness as needed
Polarized lenses sharply cut glare and enhance color
