| Abstract: |
Eyewear which is suitable for routine wear and within masks which are sealed against noxious environmental gases or penetration by water is provided by a frame made up of resilient metal parts including wires to provide the frame with a shape, which facilitates the placement of the eyewear on the head of the user while limiting the movement of the eyewear when in use so as to avoid breaking the seal of a mask inside of which the eyewear is disposed when the mask is donned by the user. The eyewear has a lens holding frame for holding lenses adjacent the eyes of the user's head and connected by a bridge across the user's nose. Flexible members bent arcuately around and in conformance with the sides of the head of the user have a kink whereby to facilitate acceptance between the sides of the head and the seal of the mask with sufficient tightness against the side of the head to limit movement of the frame and the space between the seal and the head thereby avoiding breaking of the seal when the mask is in operation.
