Wizard-like photochromic lenses are now available for the Performance Lazer SLIM. These adaptive lenses adjust from a clear to dark tint depending on the light intensity in your environment and boast a wide VLT range at 75%-17% Introducing a complete evolution in product - We’ve taken the unmistakable Lazer Face® frame and given it a complete overhaul, making them Z87+ out of the box, featuring new performance arms, with an integrated Quick-Latch side-shield system. In the comfort department you will find rubberized touch points throughout the frame also ensuring that the frames stay in place on your face. The cherry on top of the performance line is a lens matched side shield melds form and function together for a look that is flat out stunning and is entirely unique to the performance line. Performance line features include 2 mm thick lenses that meet ANSI Z.87 mass impact requirements plus an all-new extended length arm, specifically designed for our standard frame range, with new beveled emblems. The all-new Quick-Latch side-shield system provides lateral protection from debris and unwanted side light meeting ANSI Z87+ standards with side shields installed. Rubberized Hytrel® inserts are strategically placed in the arms and nose for a fit that is not only more comfortable, but grips and stays in place. Lens Technology: The variable tint range of these lenses adjusts from a very clear 75% to a very chill 17% VLT of darkness, all in under 30 seconds. So when you're inside your garage grinding off all the bubblegum welds from a sweet barn find C10, you'll have crystal clear, z87 protection. When it's time to jam outside for the 5th Home Depot run of the day, the lenses will smoothly transition from clear to grey in a matter of seconds. While these will NOT get as dark as our standard Black lenses. We picked a transition lens to provide ideal clarity indoors and as dark as possible outdoors to maximize the wearer's utility of this eyewear. 2mm thick Polycarbonate lens meets or exceeds mass impact requirements for Z87 standards, injection molded to the highest standards and tested to ensure optimal clarity, along with color and light transmission standards.
