ABSTRACT:
A system for coupling lens to an eyeglass frame includes an eyeglass frame with a lens bridge that comprises a mating wall and a coupling wall. A channel is formed between the walls. The coupling wall is arcuate with a tip that projects towards the mating wall. At least one lens is provided for coupling to the bridge. The lens has a coupling region that extends from a top edge of the lens, along both surfaces, and a distance towards a bottom edge of the lens. A first surface of the lens has a groove that extends across the lens and along a bottom perimeter of the coupling region. The groove includes a recessed cavity configured to receive the tip of the coupling wall, to snap-fit the lens to the bridge. A second surface of the coupling region is configured complementary to an inner surface of the mating wall to frictionally engage the mating wall. The lens is coupled to the bridge by pressing the lens into the channel. As the lens is being pressed into the channel, the coupling wall deflects to allow the lens to pass through the aperture until the coupling region substantially resides in the channel. The tip of the coupling wall snaps into the groove, to snap-fit the lens to the bridge. The coupling region frictionally engages the mating wall to aid with coupling the lens to the bridge.
