45cm Outdoor Road Safety Convex Mirror
Curved safety glasses are made of PC, which is soft and lightweight, but highly impact resistant and shatterproof. Compared with acrylic, polycarbonate lenses have excellent reflective properties, are UV and scratch resistant, are about 30 times more impact resistant than acrylic of the same thickness, and can withstand severe temperatures from -40°F to 257°F without breaking or melting, so they are completely safe to use even under cold frost, high temperatures, strong winds, hail and solar radiation.
