For use by firefighters or workers who must wear corrective lenses, the spectacle kit ( eyeglass kit ) can be easily inserted into the facepiece. The kit includes a wire support, rubber guide and pair of metal-frame spectacles. Desired adjustment is obtained by moving the spectacle in and out of the rubber guide and up and down the wire support.
Ultra-Elite kit uses an S-7 shape, 48 mm lens size with universal bridge.
