Abstract: The present invention discloses an eyeglasses structure which comprises a frame and a lens assembly. The frame comprises a groove for engaging with the lens assembly, an inner groove wall having plural first recesses and an outer groove wall having plural second recesses staggered with the plural first recesses. The lens assembly comprises a concave portion corresponding to the plural first recesses and the plural second recesses and engaged with the groove to form at least one ventilation area and plural guiding chutes corresponding to the plural second recesses and communicated with the at least one ventilation area and the plural first recesses.

Abstract: A nasal mask structure for eyeglasses is disclosed herein. It comprises a main body having a clamping part corresponding to a bridge of the eyeglasses and two engaging parts at two sides thereof for connecting two frames of the eyeglasses.

Abstract: An eyeglasses assembly structure is disclosed herein. It mainly comprises an upper frame having a first connecting part and two upper connecting parts; and a lower frame having a second connecting part and two lower connecting parts. The first connecting part has a receiving slot, two protrusions and two engaging slots disposed in the receiving slot, and each of the two upper connecting parts has an engaging hole. The second connecting part has two inserting blocks for correspondingly inserting into the receiving slot, two engaging blocks disposed on outer sides of the two inserting blocks for engaging with the two engaging slots, and two concave slots disposed on outer sides of the two inserting blocks for receiving the two protrusions, and each of the two lower connecting parts has an engaging member for engaging with the engaging hole of each of the two upper connecting parts.

Abstract: A glasses structure comprises a main body and a sub-frame assembled at the rear of a lens of the main body. The inner surface of a frame body of the sub-frame is attached with a pad, which pad is formed with an upper contact portion and a central contact portion corresponding to the upper edge and the central shape of the frame body. Two nose pieces are formed at the both sides of the central contact portion of the pad, and the upper contact portion of the pad are respectively contacted with the user's nose and forehead to avoid pain when the user wears the glasses. Furthermore, the colored and patterned frame body of the sub-frame is shown from the transparent lens of the main body, whereby the glasses with suitable color and pattern being chosen to dress with the user's clothes and style, increasing the user's fashion and beauty.

Abstract: The invention relates to a lens exchanging structure. Lens-frame assembling parts of a glasses frame of a main spectacle frame are assembled with lens frames. Intercalating flanges on one sides of the lens frames are correspondingly intercalated by intercalating concave parts of the lens-frame assembling parts. Positioning slots on another sides of the lens frames are inserted by positioning bumps of the fixing parts in sliding slots of the glasses frame. Therefore, when the main spectacle frame or the lens frames are needed to be exchanged, it only needs to fiddle the fixing parts to separate the positioning bumps of the fixing parts and the positioning slots of the lens frames. Then, the lens frames can be removed from the main spectacle frame. The removed lens frames can be assembled with other main spectacle frames having other styles and colors.

Abstract: The invention relates to an assembled structure of a main spectacle frame and an assistant lens frame. Sliding slots having fixing parts are disposed on inner sides of the lens frame of the main spectacle frame. Through holes are disposed in front of the lens frame and positioned to correspond to the sliding slots. The assistant lens frame is disposed on the front side of the lens frame of the main spectacle frame. Positioning bumps are protrudingly disposed on inner sides of the assistant lens frame to correspond to the through holes on two sides of the lens frame of the main spectacle frame. Tip holes are disposed on lateral sides of the positioning bumps to be inserted by tip rods for positioning correspondingly.

Abstract: An assembly structure for eyeglass lens is disclosed herein to include a one-piece lens and a frame. The frame has a connection portion in the middle thereof, from two sides of which two nose pads extend downwardly and obliquely in two opposite directions. The connection portion has a joining hole, and the lens further has a flexible snap-in element in the middle thereof for corresponding engagement with the join hole. In such a case, the lens can be easily and conveniently detachable from the frame by merely pressing the flexible snap-in element.
