Brass Knuckle Spectrum has comfort, anti-fog for all-day wear
Fogging lenses and an overall lack of comfort are the two main reasons that workers remove their eye protection. Spectrum helps prevent this issue with N-FOG anti-fog lens protection. It permanently bonds to the lens and will not wear off or wash off. Its anti-fog protection exceeds European EN 166/168.
For comfort, Spectrum features bowed, super-flex rubber temples that ratchet for custom fit. They touch the wearer only behind the ears, eliminating all pressure points. These ratcheting flexible temples offer a face-hugging design. The second-generation PivotEase nosepiece slides up and down and pivots on a hinge for added secure fit.
Spectrum brings all this to bear while also retaining its anti-scratch, anti-static, and UV protection properties.
Clear lens allows maximum light transmission without changing or distorting vision or colors. Smoke lens provides all over tint for normal outdoor conditions. Amber lens sharpens contrast and provides greater clarity in low-light conditions. Amber filters out blue light from computer screens and other electronic devices.
There are also two mirror lens finishes available. Indoor/outdoor clear mirror lenses provide all-around tint for protection from the glare of bright artificial lighting and sunlight, ideal for workers who change environments throughout the day. Blue mirror is a sunglasses style that reduces glare. (Note that the two mirror options do not include N-FOG technology.)
