Abstract: A tripod light includes a frame supporting a light assembly, and a support assembly coupled to the frame and configured to support the frame on a surface. The support assembly includes a first leg, a second leg, and a third leg. The support assembly is pivotable relative to the frame about a first axis between a stowed position in which the support assembly including the first leg, the second leg and the third leg is adjacent the frame, and a deployed position in which the support assembly including the first leg, the second leg, and the third leg extends away from the frame. Each of the second leg and the third leg is configured to rotate relative to the first leg about a second axis between a collapsed position and a respective extended position of the second leg and the third leg.

Abstract: A pair of rimless spectacles includes two lenses, a frame including two temple units and a bridge, and a connection mechanism. The connection mechanism includes a plurality of first connectors spacedly provided at the lenses at a predetermined location and a plurality of second connectors provided at a predetermined location of each of the temple units and the bridge respectively, wherein the second connectors are coupled with the first connectors respectively to couple the temple units at two outer sides of the lenses respectively and to couple the bridge between two inner sides of the lenses respectively in a tool-less manner.

Abstract: A spectacle frame includes two lenses, a frame body holding said two lenses in position, and an interchangeable decorative arrangement which includes one or more personalizing elements detachably and interchangeably affixing at a personalizing portion of the frame body, wherein the personalizing element, having a shape corresponding to the personalizing portion of said frame body, forms an add-on personal decorative item to personify the frame body so as to enhance an aesthetic appearance of the spectacle frame.

Abstract: A spectacle frame set includes a detachable spectacle frame and a utility spectacle frame. The detachable spectacle frame includes two hangers, a lens supporter extended between two inner sides of a pair of optical lenses, two first connectors provided at two front ends of the hangers respectively to detachably couple with two outer sides of the optical lenses respectively. The optical lenses are selectively assembled with the detachable spectacle frame or disassembled from the detachable spectacle frame to detachably mount the optical lenses behind the utility spectacle frame at a position that the optical lenses are overlapped aligned with the utility lenses of the utility spectacle frame respectively.
