Foldable eyewear includes first and second lens rims, a bridge portion between the first and second lens rims, connectors between the bridge and the first and second lens rims, and at least one spring positioned at a folding hinge that rotatably joins the bridge portion and a lens rim-bridge connector. The spring-hinged mechanism that joins the bridge portion and a lens rim-bridge connector allows the user to fold one lens rim on top of the other for compact storage while preventing unwanted instability and unwanted transitions between the folded and unfolded positions. The spring-hinged mechanism allows the lens rim-bridge connector to "hyper-extend" relative to the bridge portion to absorb impact/force without breaking.
