For modern eye protection designed for comfort and compatibility, use 3MTM SecureFitTM 500 series protective glasses. These protective glasses weigh just 22 g and offer an elegant and refined look. The technology for uniform pressure distribution in the time zone 3Mtm is characterized by grooved mounts that evenly distribute the pressure for greater comfort, allowing the staves to bend and self-regulate according to the size of the garment of the wearer. The design of these protective glasses provides the application of the pressure on the back of the head, less sensitive, instead of the rods, for a comfortable fit even during the quick movements of the head. Adjustable angle bars offer even greater customization, allowing the user to adapt the lenses to the characteristics of the face and to the position of the glasses. These glasses fit easily with headphones.
