Abstract: Eyeglasses with a hidden bridge are revealed. The eyeglasses include at least one frame for supporting at least one lens and a bridge arranged at the frame. The frame is provided with a bridge assembly portion which is inverted U-shaped corresponding to a nose of a human face. The bridge is a U-shaped support fixed on a top of a transverse portion of the bridge assembly portion with a U-shaped opening facing the human face so that a bottom surface of the bridge is above the transverse portion of the bridge assembly portion. Thereby the bridge is hidden behind the lens. The bridge is invisible while looking at the eyeglasses from a front side. Thus value and economic benefits that come with the eyeglasses are both increased.

Abstract: A sunglasses assembly having a simulated monolithic lens is disclosed herein. It comprises a main frame; a secondary frame disposed on the main frame and having an upper portion, a lower portion, two lateral portions connected two ends of the upper portion and the lower portion, a nose bridge portion at a middle thereof, two lenses assembly holes defined by the upper portion, the lower portion, the two lateral portions and the nose bridge portion, and two first convex ribs disposed at two inner edges defined by the upper portion, the lower portion and the two lateral portions; and a shaded optical lenses assembly having two shaded optical lenses connected to each other, wherein each of the two shaded optical lenses has a connecting segment at an inner side thereof, a recessed region on an inner surface thereof, and an engaging groove at an outer edge thereof.

Abstract: A sunglasses having a simulated monolithic lens is disclosed. It comprises a shaded optical lenses assembly having two shaded optical lenses, each of the two shaded optical lenses having a connecting segment on a side thereof for correspondingly connecting to each other and an insertion segment extended from the connecting segment; a frame having an assembling groove disposed on the bottom edge thereof to engage upper edges of the shaded optical lenses for positioning; and a nose pad having a slot to correspondingly engage with middle lower edges of the shaded optical lenses assembly and a socket disposed on the slot for tightly accommodating the two insertion segments so as to stably connect the two shaded optical lenses and to form the sunglasses with a simulated monolithic lens.

Abstract: An eyeglasses assembly structure is disclosed herein. It comprises a lens having two connecting parts at two ends thereof, two assembly members, and a pair of temples respectively and pivotally connected to the two assembly members. Each of the two connecting parts of the lens has an orientation trough. Each of the two assembly members has an embedding slot for engaging with each of the two connecting parts of the lens and a button having a positioning block for correspondingly engaging with the orientation trough.

Abstract: A quick-replacement structure of glasses lenses comprises an upper frame, a lower frame, and a fastener. The upper frame comprises a groove at the middle part, and a slot formed at the bottom of the groove and forwardly penetrating the frame wall. The lower frame comprises an insert upwardly extended from a middle section and a hole in the insert. The fastener is corresponded to the groove shape, and an inserted pin is forwardly extended from the fastener wall. When the both ends of the upper frame and the lower frame are hinged on each other, the insert of the lower frame is inserted into an upper lens recess, and the hole in the insert is corresponded to the slot of the groove, then the inserted pin of the fastener is through the slot and the hole, quickly clamping the lenses between the upper frame and the lower frame.

Abstract: A lens exchange structure of spectacles is disclosed. The lens exchange structure comprises a lens frame, a lens, a pressing part, and an elastic part. A channel is disposed on the bottom of the lens frame. An intercalation hole is disposed on the inner side of the central nose bridge. The pressing part is inserted into the intercalation hole. The pressing part has hook parts and an accommodating groove for receiving the elastic part. One terminal of the elastic part is against the wall of the lens frame, and the lens has positioning holes for receiving the hook parts. Therefore, a pressing action may be used to compress or release the elastic part to let the hook parts correspondingly hook in or release from the positioning holes. The effect of easy lens assembling and exchanging as well as stable positioning can be accomplished.
