Brass Knuckle Spike Glasses provide both long-lasting anti-fog performance and UV protection with BK-Anti-Fog+, a molecularly fused layer that resists heat, humidity, and repeated cleaning, exceeding the EN 166/168 anti-fog standard by 45 times, and blockage of 99.99% of UVA and UVB rays with UV 6 protection. Fit is highly adjustable, including a five-step ratcheting temple, flexible rubber tips, a floating reinforced-rubber nosepiece, and a soft integrated brow guard, allowing technicians to wear them comfortably all day while maintaining clear vision in harsh conditions.
