Fototec Lens information:  The Tifosi Fototec lenses are the most premium lenses Tifosi Glasses offers & come in Polarized & non Polarized options. Tifosi Fototec lenses are a Polycarbonate lens with variable tint technology ( photochromic ) that adjust to rapidly changing light conditions with superior clarity & protection. Polycarbonate is known for being strong, lightweight & shatter resistant.  Tifosi Fototec lenses have microscopic photochromic particles embedded in the lens that reacts to UV rays, so in bright sun, or cloudy conditions the lens changes tints to allow more or less visible light transmission. Tifosi Fototec lenses are industry leaders because of their lightweight, durability & fast transmission speed. All Tifosi Glasses lenses offer 100% protection from the suns harmful UVA UVB UVC rays.
Included With Purchase:  1 complete Tifosi Mast Lens set tint of your choice ( 2 lenses 1 right & 1 left ).
Understanding VLT - Visible Light Transmission:  Visible Light Transmission is the amount of light that is let through the lens, the lower  the VLT percentage the better  the performance in bright conditions by blocking more light , a high VLT percentage lets more light through the lens improving your optical clarity in low light condition
