Conforming face shield and frame system

Abstract

The present invention relates generally to safety face shield devices and more particularly to face shield devices comprising a single lens piece that conforms to the curvature at approximately the midpoint of wearer's frontal bone extending bilaterally around the wearer's face towards the temporal bones. In preferred embodiments, the safety face shield devices comprise a single lens piece (i.e., one piece) that is removably, or permanently, attached to a one piece substantially u-shaped supporting frame member through a plurality of attachment points (e.g., press fit tapered knobs). The present face shield protects the wearer's eyes, nose, mouth, and ears from direct as well as arching splashes, sprays, spatters and droplets of various liquid and semiliquid materials, and more particularly, from biological derived materials, liquids, and semiliquid materials, such as saliva, blood, mucus (e.g., nasal discharge and rhinorrhea), urine, and the like.

What is claimed is: 
     
         1 . A face shield comprising:
 a perforated lens piece; and   a frame.
