ABSTRACT:
A lens holder for visual correction within a safety mask. The bridge between the two lenses is bendable to allow contouring of the lenses to fit a person's face and a curved face plate on the mask. A hole in the bridge serves to receive a post on a bracket fixed in the mask. A hinged carrier allows a variety of brackets to be used, and the hinge is bifurcated to facilitate bending of the bridge. The lens holder is formed of an elastomeric thermoplastic, so portions of the carrier assembly are easily removable for use of the lens holder in a variety of different brackets for different safety masks.
