ABSTRACT:
A spectacle frame assembly comprises a primary spectacle frame (100) and an auxiliary spectacle frame (200). The primary and secondary spectacle frames (100, 200) each have a pair of rims (113, 213) for receiving a pair of lenses, a bridge (114, 214) separating the rims (113, 213) and arms (112, 212) secured to laterally outer portions of each of the rims (113, 213). A primary frame lug (130) is secured to each of the primary frame arms (120) and an auxiliary frame lug (230) is secured to each of the auxiliary frame arms (212). The auxiliary frame lugs (230) are each engageable with a corresponding primary frame lug (130) with the auxiliary frame lug (230) disposed on top of the primary frame lug (130) so as to secure the auxiliary spectacle frame (200) to the primary spectacle frame (100). The primary frame lugs (230) are each provided with a magnetic member (131) receivable in an open cavity (231) provided in the respective auxiliary frame lug (230). An alternate assembly utilises rimless primary and auxiliary spectacle frames (300, 400).
