3M™ SF402AF SecureFit™ Protective Eyewear, Universal, Frameless, Anti-Fog Gray Lens

3M™ Secure Fit™ Protective Eyewear Series 400 naturally adjusts the temples to individual head sizes for a customized fit to each person. This self-adjusting feature is possible through 3M's proprietary Pressure Diffusion Temple Technology, a new design with no moving parts and nothing to adjust. Designed to diffuse pressure over the ears, the glasses automatically adjust to the head of the wearer. Weighing less than 1 ounce, the durable, snug-fitting, flexible nature of Secure Fit offers a more comfortable and personal fit than old-fashion "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, eliminating the need for frequent repositioning of the glasses due to head movement. The Secure Fit eyewear 400 Series enhances comfort and security of fit with soft adjustable nose pads and dual injected padded temples. The 400 Series also feature a motion-inspired, contoured piping on the outside of the temple for an infusion of style. These versatile safety glasses help eliminate the expense of stocking multiple frame sizes at jobsites to accommodate different head sizes. The optional anti-fog coating on the lenses helps reduce the chances of fogging in hot and humid environments. Anti-fogging properties help maintain visibility and reduce the need to remove glasses to wipe away moisture from the lenses.
