Abstract
Spectacles comprising a reslient frame and lenses with cutouts along their periphery. The frame has two frame sections. Each frame section has two frame parts defining an upper frame part and a lower frame part. The upper frame part and the lower frame part are hinged together so that they can pivot relative to each other. At least one of the frame parts in each frame section has an opening to receive a lens. The lens is inserted in a space defined by the associated upper frame part and an additional frame section which extends parallel to the associated upper frame part. The additional frame section has two short bent ends received within a respective lens cutout. These short ends are joined to the associated upper frame part. Each frame part can be displaced relative to its corresponding other frame part to widen the opening defined by the both frame parts for receiving a lens.
