The 3M™ Visitor safety glasses are safety glasses for your visitors, which can be worn over spectacles, but also alone. The protective goggles are a flexible solution to provide protection to guests in your plant, regardless of whether they wear spectacles or not. They have a light, transparent polycarbonate glass with a moulded integrated side plate and eyebrow protection for additional safety. The glass, with the optical class 1, only minimally disturbs the view and protects your visitors in different environments.
