摘要:
Spectacles having a lens frame and arms connected thereto and a retaining strap which can be fastened to the spectacles. A receiving device is provided on the free end of at least one arm, which receiving device interacts with a connecting element to which a retaining strap is undetachably fastened, e.g. moulded on. A plurality of receiving devices can be disposed at predetermined positions between the front end of each arm and the free end thereof. This has the advantage that the retaining strap can be adapted individually to the shape of the head, the hair length and possible individual preferences of the wearer of the spectacles. Thus the retaining strap can be immovably fastened not only to the free end of the arm but also to a front end of the arm, that is to say where the arm adjoins the hinge, and all intermediate positions.
