3M Smart Lens Protective Eyewear, 13407 Photochromatic Lens, Black Frame
3M™ Smart Lens™ Protective Eyewear features photochromic lenses that lighten and darken as outdoor lighting conditions change. That means changing outdoor light conditions doesn’t require changing eyewear or carrying several pairs of safety glasses anymore. Designed for comfort, the glasses come with spring adjusted temples that provide a customized fit on either narrow or wide faces, a soft adjustable nose bridge, and a nylon brow that’s gentle on the forehead. The impact-resistant polycarbonate lenses absorb 99.9% UVA and B rays.
