ABSTRACT:
A lightweight face shield which protects the face of the wearer from debris and/or hazardous materials, such as biological materials, and is particularly well suited for medical and dental applications. The face shield utilizes a two-piece tiered structure with a preferably canted retention frame joined through an inclined structure member to a shield frame member below which is retained a transparent shield, and above which a minishield. The shield frame member is retained forward of the retention frame member so as to retain the peripheral portions of the shield separated from the face of the user, providing improved ventilation and reduced fogging of the transparent shield. A trampoline style support arm is described that provides solid retention, compliant comfort, and reduced material requirements. Optional locking hinge assemblies for the support arms and a nose bridge are also described.
