3M SecureFit 400 Protective glasses, black/green frame, scratch-resistant

For greater comfort and elegant design, use 3MTM SecureFitTM 400 series protective glasses. Our protection glasses weigh just 19 g and are equipped with the technology for uniform pressure distribution in the time zone 3Mtm that allows contact points on double injection padded bars to adapt naturally to the size of the head of the wearer, offering a safe and comfortable fit. The adjustable and soft hanger allows an even greater customization of fit and reduces the slip caused by head movements. The wide flexible bars above the ears offer excellent side protection and allow for use with earphones. The enveloping design offers the user a wide field of view. Polycarbonate lenses without mounting are available with anti-fog treatment and scratch coating for longer durability and visibility.
