Abstract: Eyewear having replaceable lenses, with an illustrative embodiment including a frame, two temples, temple-connecting members extending outwardly from opposing ends of the frame and affixing the temples to the frame; a nose bridge; bridge-connecting members extending outwardly from two points centrally located on the frame and affixing the nose bridge to the frame; nose pads; and a plurality of interchangeable lenses. The lenses, which may be sunglass lenses, are composed of somewhat pliable material and have a perimeter defining at least two collinear recesses, with the recesses capable of selectively and releasably coupling with the temple-connecting members and the nose bridge-connecting members, thus securing the lenses to the frame. A case with a padded interior and fitted storage recesses is used to protect eyewear and lenses not in use.

Abstract: The elastic joint for eyeglasses comprises of a one-piece flexible component that is attached to the joint between the temple and the lens frame. The one-piece flexible component has an oblong-circle profile defining a through-hole near one extremity of the oblong profile and a hinge joint at the other extremity of the oblong profile. The hinge joint on the elastic joint for eyeglasses is hinged to the joint between the temple and the lens frame with the through-hole extremity positioned at the joint between the temple and the lens frame. The elastic joint for eyeglasses will maintain a comfortable tension to retain the eyeglasses on the user.
