Fogging lenses can strike in both indoor and outdoor working conditions. Brass Knuckle Spectrum (BKFLEX-4040N) eye protection has options to fight fog no matter where work has to get done. This powerful ANSI Z87.1+ protection weighs less than 1 ounce, and the rimless lenses are manufactured with exclusive BK-Anti-FOG protection. Spectrum pops with color, too, as each lens color in the family sports a unique, corresponding temple color.

Temperature changes, humidity, sweat, rain and moisture all contribute to lens fog. Spectrum Clear Lens allows maximum light transmission, indoors or out, without changing or distorting vision or colors (91% of light passes through). Spectrum Smoke Lens provides all-over tint for normal outdoor conditions (18% of light passes through). Amber and blue lenses are also available.

BK-Anti-FOG lens protection lasts 15 times longer than EN 166/168 standards. The special coating is permanently bonded directly onto the lens surface and will not wear or wash off. Glasses retain fog-fighting properties for a longer duration with no reapplying and no maintenance needed. www.brassknuckleprotection.com
