New Brass Knuckle Spectrum safety eyewear

March 9, 2021  By Rock to Road

Brass Knuckle Protection says fogging lenses and an overall lack of comfort are the two main reasons that workers remove their eye protection. Brass Knuckle Spectrum (BKFLEX-4040N) safety glasses are flexible and offer anti-fog protection.

Spectrum offers 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 true face-hugging design that inspires compliance. Capping it off, the second-generation PivotEase nosepiece slides up and down and pivots on a hinge for added secure fit.

This collection also pops with colour, inspiring the Spectrum name itself. Each lens colour in the family sports a unique, corresponding temple colour.


Clear lens allows maximum light transmission without changing or distorting vision or colours. Smoke lens provides allover 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 trendy and cool sunglasses style that reduces glare.
