Abstract: A replacement structure of eyeglasses lens is disclosed. A frame comprises two circular openings corresponding to each other, at least one recess at the periphery of each circular opening, and a sliding slot connected with the recess. A lens rim is around the lens periphery, wherein the rim shape is circular to correspond to the circular opening for assembling the rim in the circular opening, and a projection is protruded from the rim periphery to correspond to the recess and embedded in the recess. When the rim is rotated, the projection is moved into the sliding slot to fasten the lens. Accordingly, the assembly and disassembly of the lens with the frame does not require any tools, being simpler, easier, and faster. Furthermore, the different color and style of the rim is used to match with the frame, so the use is richer and more is varied to attract consumers' attention.

Abstract: An interchangeable frame for eyeglasses comprises an upper frame and a lower frame, which are respectively formed corresponding lens-assembling portions. The connection site between the upper frame and the lower frame has a connection block and a connection notch, corresponded to connect to each other, and the both sides of the connection block and the connection notch have a ditch and a flange, engaging upon each other, making the upper frame and the lower frame connect to form in one. Therefore, according to the required, the upper frame and the lower frame can be assembled and disassembled freely to form the semi-rim eyeglasses or the full-rim eyeglasses.

Abstract: Eyeglasses with a changeable frame are revealed. The eyeglasses include an upper frame and a lower frame. The upper frame and the lower frame have a lens assembly portion and a lens assembly part, respectively. The upper frame and the lower frame are disposed with locking slots and projections respectively. The projections are corresponding to and joined with the locking slots. The upper frame and the lower frame are connected into one part by locking protrusions of the projection into the concaves of the locking slots correspondingly. Thus users can assemble or disassemble the upper frame with the lower frame for changing the eyeglasses into half-frame eyeglasses or full-frame eyeglasses.

Abstract: A spectacle structure with transformable frames is disclosed. In the spectacle structure, an upper frame and a lower frame have corresponding lens assembling parts, as well as corresponding latched holes and latches to combine the upper frame and the lower frame to one spectacle frame. When the upper frame and the lower frame are going to be separated, push resistant blocks of the upper frame can be pushed to move the latches away from the latched position. Accordingly, the upper frame and the lower frame can be separated or assembled to form half-rimmed or full-rimmed spectacles according to the user's needs.

Abstract: This invention is related to a spectacle structure with transformable frames. An upper frame and a lower frame of the spectacle structure mainly have corresponding lens assembling parts. A fixing part is pivotally connected to an assembling rod of the upper frame. A connection section against the assembling rod of the upper frame is disposed in the lower frame. A carrying part of the fixing part support the bottom of the connection section. A positioning flange stops in front of the connection section to combine the upper frame and the lower frame to be as one frame. Accordingly, the upper and the lower frames can be detached to transform between a half-rimmed spectacles and a full-rimmed spectacles depending on needs.

Abstract: This invention is related to an eyeglasses temple structure. Two assembly slots are formed at two ends of a frame for assembling with a positioning element, respectively. A pivot element is pivoted on the assembly slot through a hinge part of the positioning element. A protruding part at a wearing portion is inserted into the assembly slot through an end opening of the frame, and the protruding part has a pit for embedding and fixing an embedding part of the hinge part. Therefore, when the wearing portion is assembled with the frame, the wearing portion is positioned via the positioning element which is pivoted on the frame. When replace the wearing portion, the positioning element is pressed to enable the wearing portion to separate from the frame, so the replacement of the wearing portion is more quickly, easy, and convenient.

Abstract: This invention is related to a lens and frame assembly structure for glasses. A lens assembly slot for assembling a lens is formed on a frame. Two sliding grooves are corresponded to the two side of the lens assembly slot respectively for assembling the fastening elements. Long slots are formed on the top and bottom surface of each sliding groove respectively for embedding retaining blocks which are formed on the top and bottom surface of each fastening element, thereby allowing each fastening element sliding in each sliding groove without separation. Furthermore, an embedding part projects out from each fastening element toward the lens assembly slot for embedding the embedding part into the recess of the lens. Therefore, the fastening elements on the frame are pushed to assemble or separate the lens and the frame without using any tools.

Abstract: A lens assembly structure of half frame spectacle mainly comprises a half frame having at least one lens mounting portion. At least one lens is to be assembled to the corresponding lens mounting portion with its projections fitted into inlay grooves of the lens mounting portion. Two link assembly cavities are respectively provided on both sides of the half frame within which links can be respectively assembled. Each link has a limit hole provided for passing-through of a fastening member. Each temple is pivotally connected to the corresponding link. The lens can be fixed firmly in the half frame and replaced very easily.

Abstract: An eyeglasses assembly structure is revealed. It comprises a lens having a groove and an orientation trough on both peripheral edges thereof and a pair of temples. Each of the temples has a concave slot for engaging with the lens, and the concave slot has a pivot for pivotally connecting to the groove and a positioning rod for engaging with the orientation trough.

Abstract: An assembly structure of spectacle is provided, in which one end of a connecting member of a wearing element (such as a temple) has a cut-out portion, which is fitted with an inverse cut-out portion provided on a frame connector. Each of the connecting member and the frame connector has a bore and an integral guiding slot provided beside the bore. A coupling member having an axle rod and a fixing block is used to couple the connecting member and the frame connector together. By the assembly of the connecting member, the frame connector and the coupling member, user can assemble different style of wearing elements such as temples or strap according to his preference or dressing as required.

Abstract: A foldable frame of eyeglasses includes two fronts pivotably connected two ends of a bridge. Each front has an installation portion so as to accommodate a lens therein. A first plate extends from the top edge of each front and toward the rear side of the front. Two temples are respectively and pivotably connected to the two fronts and each temple includes two sections which are pivotably connected to each other. A second plate and a shade respectively extending from the top edge and the bottom edge of the section that is pivotably connected to the front corresponding thereto. The second plate extends inward and toward the other temple and the lower edge of the shade reaches the lower edge of the front corresponding thereto. The foldable frame is mounted to the existed frame and protects the user's eyes from wind, dust and ultra-violet rays.

Abstract: A ventilation structure of eyeglasses is revealed. It comprises a spectacle frame having a lens assembly portion, a concave slot extended from a peripheral edge of the lens assembly portion for engaging with a lens, and a plurality of air guide channels formed in the concave slot, wherein each of the plurality of air guide channels is extended from an opening of the concave slot, pass front and rear sidewalls of the concave slot and towards a base of the concave slot for communicating with the concave slot.

Abstract: An eyeglass lens structure is disclosed herein to a substrate, a polarizing layer, a photochromic layer, a reinforcing layer, an isolation layer all on a top surface of the substrate of a lens, and an antifogging layer on a bottom surface of the substrate, for effectively reducing eye hurts by glare, protecting eyes from glare, preventing the lens against scratches. from sticking dirt and water, and from fogging.
