Unitary spherical flexible eyewear pane having two separate individually optically compensating lens elements and eyewear for sportsmen having such a pane

摘要

The spherical flexible sheet lens is releasably secured to and within the channel of an eyewear frame. The lens defines two distinct lens elements and a bridge part spacedly integrally interconnecting the first and second lens elements. The bridge part includes a nose opening for free passage of the wearer's nose. A transverse lip forms the top of said lens to be inserted within the channel and secured to the frame. Each lens element: is of generally spherical shape; is thickest in its center portion and gradually thinner towards its edgewise portion to control the optical distortion brought about by a curved plastic lens; is adapted to register with a corresponding one of the two eyes of a wearer; defines an interior surface in facing register with the wearer's face and an exterior surface; includes an inturned web interconnecting the top and inner sides of each lens element to the lip and bridge part, respectively, the lens element being outwardly offset relative to said lip and bridge part.
