Tifosi Fototec Lenses adjust rapidly for superior clarity and protection through your changing day. In bright sun, Fototec darkens quickly so you'll never squint. Then, as light fades, they become more transparent. Microscopic photochromic particles embedded in the lens react chemically to UV rays - they change shape, expand and absorb light thus darkening the optics. With cloud cover, the particles return to their previous state letting through more light. Like all Tifosi lenses, Fototec lenses block 100% of harmful UVA/UVB rays.
