ABSTRACT The present invention relates to the use of shape memory material in engaging or otherwise coupling various separate elements of eyeglasses into a single structure, such as an eyeglass frame including at least one shape memory rim which recovers to a memory configuration from a deformed state in response to templerature changes thereof. Each such shape memory rim retainably engages or, alternatively, releases a respective lens as such rim recovers to its memory configuration from its deformed state. A method of fabricating the frame is also included. Moreover, a fastener for coupling a temple to a lens--or a rim surrounding a lens--and a fastener for coupling a nose bridge between two lenses--or the rims thereof--are provided. Each temple may be recovered from a deformed configuration with the applying of sufficient heat thereto.
