ABSTRACT:
The inner sides of left and right lens rims constituting the main body of a frame for multifocal spectacles are provided with respective guide portions extending downwardly from a bridge connecting the rims together. Left and right nose-pads of a nose-pad member are secured in the guide portions under tension using left and right resilient pieces configured to gradually curve away from each other. This makes it possible to move the nose-pads up and down smoothly and reliably.
