Photochromic lens ightens and darkens with changing outdoor light conditions. Anti-scratch coated polycarbonate lens reduces reflective glare and absorbs 99.9% UVA & UVB and meet the requirements of ANSI Z87.1-
2015 Standard as an Impact Rated spectacle.

3M™ Pressure Diffusion Technology allows temples to naturally adjust to individual head sizes reducing the need to stock multiple frames and work sites


Weighing less than 1 ounce, the durable, snug-fitting, flexible nature of the SecureFit offers a more comfortable and personal fit than the old-fashioned "one-size-fits-all" glasses that are rigid and unyielding in design. These glasses adapt to the wearer, rather than the other way around. The snug fit also helps keep the glasses securely in place as the wearer looks up and down or side to side, reducing the need for frequent repositioning of the glasses due to head movement.
