History
Headgear mounted mirrors were first developed in the early 1970s as a bicycle safety accessory by a dentist, Dr. Jack Greenlaw,[1] who suggested using small, round dental mirrors mounted on headgear as safety devices. Demand for the mirror exceeded his ability to manufacture them by hand, resulting in outsourcing the manufacturing to that of injection molded plastic. Several other brands followed, initially designed for the bicycle industry then later as an industrial and tactical device. The success of mirrors mounted on bicycle helmets continued for decades, finally being adopted by construction and industrial workers as a safety device, on helmets of snowmobilers (3), and in tactical environments like Airsoft and SWAT applications adding a similar level of safety as mirrors on vehicles.

Hard hat mirrors are typically very small due to the close visual proximity and are made of
They are used in dangerous workplace environments by pedestrian workers or by operators of small equipment like
In 2000, Washington State's Department of Labor and Industries carried out a study of hard hat mounted mirrors' effectiveness as a run-over and back-over safety device, entitled "Optical Properties of Plane and Convex Mirrors: Can Mirrors Be Used to Enhance Construction Flaggers' Safety?" The report concluded that: "Given that image perception is a problem with small-radius-of-curvature
