Even if you have never really noticed them, you have seen them. Convex mirrors are used in warehouses, retail stores, parking garages, and even as traffic mirrors.
The curvature of a convex mirror, with the highest point rising to the center, enables a larger view of a reflected area than a flat mirror may provide. The lenses of a convex mirror may be constructed from acrylic, the most popular, glass, and stainless steel, the most durable. As far as backing, convex mirrors are available with a sturdy ABS plastic backing, with a treated hardboard backing, stainless steel backing, or even as a lens only, with no backing.
