Claim:
Eyewear comprising: a frame; a lens configured to be fitted against the frame; an engagement mechanism comprising a gate, a hinge pin, and a latch member, the gate being coupled to the frame and being operative to move along a first path between an open position and a closed position, the latch member being functionally connected to the gate and being constrained to move along the first path together with the gate upon movement of the gate, the latch member further being movable relative to the gate along a second path between a disengaged position and an engaged position to disengage or engage with at least one of the lens and a portion of the frame to prevent movement of the gate relative to the frame when the latch member is in the engaged position to maintain the lens fitted against the frame, wherein the first path is different from the second path, the first path being a rotational path, wherein the hinge pin defines a generally vertical axis about which the gate and the latch member rotate when moving between the open position and the closed position.
