Abstract
A pair of spectacles includes a main frame, auxiliary frames removably mountable in the main frame, and a nose rest fixedly disposed on the main frame. The lenses are fixed in each auxiliary frame and to replace the lens, it is only necessary to remove the auxiliary frame and install another auxiliary frame with a new lens to achieve convenient lens replacement. The fixation, disassembly, and assembly of the auxiliary frame and the main frame are made convenient by connection via magnetic attraction at one end of the auxiliary frame and a positioning tab at another end thereof. For disassembly, the magnetically attracted end is first separated, followed by removing the auxiliary frame to separate the positioning tab from a positioning slot. For assembly, the positioning tab is first placed in the positioning slot, followed by fixing the magnetically attracted end.
