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.
