Abstract: A protective glasses assembly has an integrally formed designed lens, a frame made of a soft material and fitted in with the designed lens and a band. A plurality of spaced apart male portions extend rearward from edges of the designed lens for being inserted into sockets of corresponding covering elements extending forward from edges of the frame, and a number of air-passing grooves are located on upper and lower edges of the frame. The designed lens has engaging blocks respectively formed on left and right sides for engaging with boundary holes of connector members connected with both ends of the band, and through holes for receiving inner inserting sections of the connector members. Thereby the designed lens and the frame can be assembled promptly and kept in a stable position.

Abstract: An eyeglass assembly having a secondary eyeglass frame combined with a main eyeglass frame by a protection strip is provided. A pair of eyeglass temples connected to the main eyeglass frame is adjustable to an angle as desired. When the eyeglasses are used for sport purpose, a strap may be fastened to the eyeglass temples by inserting a stopping portion of an engaging member of the strap into a preset hole on the eyeglass temple and allowing the stopping portion engaged with a crossed inner groove adjacent the hole by rotating at a direction such that the strap and the eyeglass temples can be quickly fastened to achieve stable positioning or quickly disassembled when not in use.

Abstract: A positioning structure for auxiliary eyeglasses comprises an auxiliary eyeglass frame of auxiliary eyeglasses with an additional function, having a bridge provided with a receiving space and a through hole formed on a back wall of the receiving space. A protective strip combined to the auxiliary eyeglass frame is provided with an inserting portion extending downwardly from a central portion and having a first projection projected rearward so that the inserting portion can be inserted into the receiving space with the first projection being engaged with the through hole. A pair of second projections are provided on each end of the protective strip for being inserting into a recess formed on each end of a main eyeglass frame. Hereby the auxiliary eyeglass frame with the protective strip can be stably and speedily attached/detached to/from the main eyeglass frame.

Abstract: A fixing structure for lenses and a frame of eyeglasses is provided. A combining element integrally formed on a top of said styled lenses is concavely provided with a containing groove facing inwardly at a segment corresponding to styled lenses. Two sides of the containing grooves are provided with a wider distance at the outer end and narrow in toward the inner end. A hole is provided at a center and two sides on an upper flange of the combining element, respectively, so as to contain the strip on the two sides of the frame formed wider on the outer end and narrower on the inner end. The strip of the frame with the middle portion extended into a nose pad portion is provided with a protrusion corresponding to the hole opened on the combining element on top of the lenses, such that the two may be engaged together when assembled. A concave portion is provided at a bottom of a leg connecting element on the two sides of the frame, so as to support the two ends of the lenses when assembled.

Abstract: A headband fastening structure for ski goggles includes a lens fitted in a goggle frame and a headband. The lens and having a pair of extending segments on opposite sides, each extending segments is provided with a wedge portion upwardly sloped toward the front thereof and a recess on one side adjacent the goggle frame. A fixing hole is provided on each of the fastening segments, wherein each of the inset segments extending along the inner side of each of the fastening segments with a predetermined interval. The insert segments are inserted into the respective recesses of the extending segments of the lens. Each fixing holes is pushed toward the corresponding wedge portion smoothly and gradually along the slope of the wedge portion until the fixing hole retains the wedge portion firmly. The ski goggles and the headband are thus assembled together and positioned in a prompt and steady manner.

Abstract: An angle adjustment mechanism for eyeglasses comprises a connection device including a rear engagement member, an outer cross aperture, an inner cavity, a front bar, an outer recessed portion, and a ridged section; a temple including a connection section, a front cut-out member, a hole through cut-out member, a transverse rhombic aperture abutted on inner end of hole, a recess on a shoulder between cut-out member and connection section, and a peg projected from a front end of cut-out member; and a dumbbell shaped snapping device passed through the apertures wherein engagement member is engaged with cut-out member with bar received in recess to communicate cross aperture with rhombic aperture, snapping device is inserted into hole to pass its end abutment member through the apertures to be flush with cavity, abutment member is rotated to urge against cross aperture, and peg is slidably engaged with ridged section.
