Abstract: A flexible auxiliary clip-on frame for tension mounting to a mating or primary spectacle frame. The clip on may be used to house sunglasses or any other frames necessary. The primary spectacle frame does not have to be constructed with any special features in order to mate with the auxiliary clip-on assembly. The primary spectacle frame assembly has the typical eyewear components including the eyerim, end pieces, rimblocks, bridge, temple, and optionally, nose pieces. Due to its flexible nature, the entire body of the auxiliary clip-on assembly acts as a spring. The spring-like qualities of the auxiliary clip-on assembly are used to securely fit the auxiliary clip-on assembly onto the primary spectacle frame assembly through the use of end piece retainers, without the need for magnets or any other fixture.

Abstract: An eyeglass device for magnetically and securely attaching an auxiliary lens frame to a primary eyeglass frame. The relative motion of the auxiliary lens frame and the primary eyeglass frame is limited even when the wearer of the engaged and attached lenses is active due to the attractive magnetic forces of the engaged lenses and the flanges incorporated on the primary lens frame.
