Abstract
An elastic strip member is interposed between the inner peripheral surface of a spectacle or sunglass frame and the outer peripheral surface of a spectacle or sunglass lens so as to prevent the lens from colliding with the frame, and further, ridges raised from opposite side surfaces of the strip member are inserted into a groove formed on the inner peripheral surface of the frame and a groove formed on the outer peripheral surface of the lens so as to prevent the lens from falling off the frame.
