The CONTOUR glasses have a durable polycarbonate frame with TIPGRIP temples made from nylon and thermoplastic rubber, so they are non-slip and provide a secure fit. The glasses also feature a non-slip nose bridge, allowing them to sit comfortably on the user’s face. The impact resistant polycarbonate lens uses Bolle’s PLATINUM technology. This permanent coating is applied to both surfaces, making the lens highly scratch-resistant. It also makes them resistant to aggressive chemicals and helps to prevent fogging. Bolle CONTOUR Safety Glasses are one of our best-selling forms of eye protection. The glasses are sturdy, comfortable, lightweight (21g) and above all effective, providing superb all-round protection. For example, the glasses provide protection from mechanical risks and ultraviolet light, and are anti-fog, anti-static and scratch resistant. Tested and certified to EN 166 and EN 170 standards.
