This replacement lens is designed for ESS FirePro goggles and fits a universal eyewear size. It serves professionals who need a direct, compatible spare for their existing protective eyewear. The hi-def yellow tint enhances contrast in low-light or overcast conditions. Buyers should confirm their current goggles are the FirePro model before ordering.

Practical Limits of ANSI Z87.1-2010

The lens meets ANSI Z87.1-2010 for high-impact protection and U.S. MIL-PRF-31013 for military ballistic fragmentation standards. Polycarbonate material provides 100 percent UV protection and a scratch-resistant coating. These standards define the rated impact velocities and optical clarity requirements. The lens does not address hazards outside these specific test parameters, such as chemical splash or infrared radiation.

Compatibility Check Before Ordering

Verify that your current goggles are the ESS FirePro model, as this lens is shaped specifically for that frame. Ensure the universal size designation matches your existing eyewear fit. Inspect the frame for damage that could prevent a secure lens lock. No other ESS models or third-party frames are supported by this part number.
