Performance Fog Technology (PFT) is a water washable, hydrophilic anti-fog coating that is cured and permanently bonded to the lens of select safety eyewear from YourGGS. These PFT lenses absorb moisture and spread it consistently over the lens to further reduce fogging effects compared to standard anti-fog lenses. These eyewear styles are also impact, abrasion, UV, and chemical resistant. Click here for more information about Performance Fog Technology Eyewear
