Abstract: A protective eyeglass assembly includes a unitary, decentered lens piece integrally molded from a transparent plastic material. The lens piece includes left and right lens panels connected by a central bridge portion. The left and right lens panels each have a lens body with a front surface and a rear surface, the front and rear surfaces defining a lens thickness therebetween. The front surface conforms substantially to a portion of the surface of a sphere having a first center whereas the rear surface conforms substantially to a portion of the surface of a sphere having a second center. The first center and the second center are offset from one another to taper the lens thickness. A frame supports the lens piece on a wearer. Alternatively, temple bars can be hingedly mounted directly onto the lens piece for supporting lens piece on the wearer.

Abstract: A protective eyeglass assembly includes a frame having left and right lens frame portions, lens receiving apertures in the frame portions, a central bridge portion connecting the frame portions, and left and right temple bars. The eyeglass assembly further includes an integrally formed lens piece which is adapted to be detachably secured to the frame so that a user can interchange the frame and/or replace the lens piece. The lens piece includes left and right lens panels, a central bridge portion connecting the lens panels, left and right side shields, and left and right upper shields. The lens piece is received in assembled relation with the frame with the left and right lens panels aligned in registry with the left and right lens frame portions.

Abstract: A visor for a protective helmet, the visor comprising at least one transparent panel and a frame which receives substantially the entire periphery of the panel in a groove, recess, or the like carried by the frame in a manner which permits rapid changing of the transparent panel. The frame comprises at least two frame parts pivotably connected with one another. In a closed position of the frame, these frame parts can be firmly connected to one another, while in a pivoted position of at least one frame part, the transparent panel can be removed from the groove recess, or the like.

Abstract: A protective device for protecting the face of a user includes a face shield made of flexible, shatterproof plastic and a guard pivotably mounted on the shield and at least partially covering it. The guard is made of scratch-resistant glass. The guard may be mounted over a cutout or opening in the shield and can be pivoted away.
