Description

Technical Field

[0001] This disclosure pertains to the field of eyewear technology, and more specifically, relates to eyeglasses. Background Technology

[0002] Eyeglasses typically consist of a lens, frame, and temples. In some situations, eyeglasses need to accommodate multiple different lens types. For example, safety glasses are often required when entering a factory environment or engaging in certain sports. However, standard safety glasses do not correct vision. People with nearsightedness who need to wear safety glasses must wear contact lenses or wear protective covers over their regular glasses, which is less comfortable.

[0003] In addition, current eyeglasses have the problem of insufficient lens strength. When subjected to impact, the lenses are prone to cracking or even breakage, posing a safety hazard.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this disclosure is to provide eyeglasses with strong impact resistance.

[0006] Eyeglasses consist of the lens and the frame, among which,

[0007] The lens body includes two lenses and a lens connector that connects the two lenses;

[0008] The eyeglass frame includes a frame and a nose bridge. The frame is arranged around a portion of the side of the lens, and the nose bridge is arranged adjacent to the lens connection.

[0009] The lens includes an optical part and an outer edge part. The outer edge part surrounds the optical part entirely or partially outside the optical part and is connected to the lens connecting part.

[0010] The outer edge is thicker than the optical part.

[0011] In one exemplary embodiment of this disclosure,

[0012] The thickness of the outer edge increases from the inner side adjacent to the optical part to the outer side away from the optical part.

[0013] In one exemplary embodiment of this disclosure,

[0014] The optical part includes a main body, an inner canthus extension, an inner canthus extension, and an outer canthus extension, all of which are integrally formed.

[0015] The main body is elliptical in projection along the thickness direction of the optical part. The inner canthus extension protrudes towards the lens connection on the side of the main body closer to the lens connection. The outer canthus extension protrudes away from the lens connection on the side of the main body away from the lens connection. The inner canthus extension is located between the inner canthus extension and the outer canthus extension, and the inner canthus extension protrudes in the main body in a direction perpendicular to the line connecting the two lenses.

[0016] In one exemplary embodiment of this disclosure,

[0017] The lens has an inner surface, and a top surface and a bottom surface adjacent to the inner surface. The lens connecting part is located on the inner surface, and the top surface and the bottom surface are opposite to each other.

[0018] The extended portion of the eye protrudes towards the bottom surface.

[0019] In one exemplary embodiment of this disclosure,

[0020] The width of the outer edge at the point adjacent to the outer corner of the eye is the maximum width of the outer edge.

[0021] In one exemplary embodiment of this disclosure,

[0022] The entire lens body protrudes in the direction of lens thickness;

[0023] The curvature of the end of the lens near the lens connection is less than the curvature of the end of the lens away from the lens connection.

[0024] In one exemplary embodiment of this disclosure,

[0025] The lens and the lens connection part are integrally molded.

[0026] In one exemplary embodiment of this disclosure,

[0027] A first insert is provided on one side of a lens, and the first insert is made of metal.

[0028] A second insert is provided on one side of the other lens, and the second insert is also made of metal.

[0029] The first insert and the second insert are welded together to form the lens connection.

[0030] In one exemplary embodiment of this disclosure,

[0031] The curvature of the lens body is continuous at the junction of the lens and the lens joint.

[0032] In one exemplary embodiment of this disclosure, the eyeglasses further include a first temple and a second temple connected to opposite ends of the frame;

[0033] The first temple is connected to the frame via a temple adjustment mechanism, which includes a first pivot, a second pivot, a first fork, and a second fork. The first pivot and the second pivot are perpendicular and fixedly connected.

[0034] The first fork is located on the frame, and the second fork is located at one end of the first temple. The first fork is hinged to the first pivot, and the second fork is hinged to the second pivot.

[0035] The eyeglasses disclosed herein have two lenses connected as a single unit via a lens connector, which can disperse the impact force throughout the entire lens body upon impact. Simultaneously, while ensuring good optical visibility, the outer edge of the lens has minimal impact on visual effect and imaging accuracy. The outer edge of the eyeglasses disclosed herein is thicker than the optical element, significantly increasing lens strength without significantly affecting visual effect. Furthermore, in an exemplary embodiment of this disclosure, the outer edge can increase in thickness from the inner side adjacent to the optical element to the outer side away from the optical element; that is, the overall thickness of the lens can increase from the center to the edge, resulting in higher overall lens strength.

[0052] The technical solutions in the exemplary embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. The exemplary embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure. Therefore, it should be understood that various modifications and changes can be made to the exemplary embodiments without departing from the scope of protection of this disclosure.

[0053] Unless otherwise specified or stated, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] Furthermore, it should be understood that the directional terms such as "upper," "lower," "inner," "outer," "top," and "bottom" described in the exemplary embodiments of this disclosure are merely for convenience, describing the position and state when conventionally wearing glasses, or describing the angles shown in the accompanying drawings, and should not be construed as limiting the exemplary embodiments of this disclosure. Those skilled in the art will understand that after rotating or changing the direction and angle of observation in the exemplary embodiments of this disclosure, "upper" may also become "lower," "left," or "right," and such changes will not hinder the understanding of those skilled in the art.

[0055] Furthermore, the terms "first" and "second" are used only as markers and are not a limitation on the number of objects they represent.

[0056] Eyeglasses typically consist of a lens, frame, and temples. Currently, eyeglasses come in various types and are worn in different scenarios. For example, nearsighted individuals need glasses with vision correction functions; those who need to enter environments such as factories need protective and impact-resistant glasses. However, typical safety glasses do not correct vision. Nearsighted individuals need to wear contact lenses or protective covers over their regular glasses, which is uncomfortable and aesthetically unappealing. If a day's itinerary involves multiple scenarios, carrying multiple pairs of eyeglasses is necessary, which is very inconvenient.

[0057] Furthermore, when nearsighted individuals engage in some intense sports activities, their glasses have poor impact resistance and low structural strength. When subjected to impact, the lenses are prone to cracking or even being damaged, posing a safety hazard and affecting the effectiveness and motivation of the sport.

[0058] To address the aforementioned problems, this disclosure provides a pair of eyeglasses, for reference. Figure 1 As shown, the device includes a lens body and a frame. The lens body includes two lenses 1 and a lens connecting part 2 connecting the two lenses 1. The frame includes a frame 3 and a nose bridge 4. The frame 3 is arranged around a portion of the side of the lens 1, and the nose bridge 4 is arranged adjacent to the lens connecting part 2. (Reference) Figure 2As shown, the lens 1 includes an optical part 13 and an outer edge part 14. The outer edge part 14 surrounds the optical part 13 entirely or partially outside the optical part 13. The outer edge part 14 is connected to the lens connecting part 2. The thickness of the outer edge part 14 is greater than that of the optical part 13.

[0059] refer to Figure 1 and Figure 2 As shown, the two lenses 1 of this disclosure are connected as a whole by the lens connecting part 2, which can disperse the impact force to the entire lens body when subjected to impact. Meanwhile, while the optical part 13 can ensure a good optical transmission range, the outer edge 14 outside the optical part 13 has little impact on visual effect and imaging accuracy. The outer edge 14 of the glasses of this disclosure is thicker than the optical part 13, which can significantly increase the strength of the lens 1 without significantly affecting the visual effect. Furthermore, in an exemplary embodiment of this disclosure, the outer edge 14 can increase in thickness from the inner side adjacent to the optical part 13 to the outer side away from the optical part 13; that is, the overall thickness of the lens 1 can increase from the center to the edge, resulting in higher overall strength of the lens 1.

[0060] The inventors also discovered that when making glasses with vision correction function, since the optical parameters of the lens 1 need to match the wearer's vision, the usual method is for the wearer to send the corresponding optical parameters of the lens 1 to a lens processing factory after their vision is accurately measured through an eye exam. Professional technicians then use optical processing equipment to process the left and right lenses 1 separately, and then assemble the lenses 1 into the finished frame 3, with the left and right frames 3 connected by a nose bridge 4. This method is rather cumbersome and complex, and consumers sometimes need several days to receive complete glasses. Moreover, glasses assembled in this way have relatively low strength. As for glasses with protective functions, although they have higher strength, they usually do not have vision correction function. They are mass-produced and sold by factories, and their appearance is usually bulky, with no choice in size or appearance.

[0061] Therefore, the purpose of this disclosure also includes improving the versatility of eyeglasses, making them suitable for daily wear as well as most labor protection scenarios and outdoor work scenarios, facilitating lens replacement, and providing strong impact resistance so that the lenses are not easily detached from the frame.

[0062] The following is in conjunction with the appendix Figures 1 to 12 The eyeglasses disclosed herein are described in further detail.

[0063] refer to Figure 3As shown, lens 1 has an inner surface 101 and a top surface 102 and a bottom surface 103 adjacent to the inner surface 101, with the top surface 102 and bottom surface 103 facing each other. When wearing the glasses of this disclosure, the inner surface 101 of lens 1 is the side of lens 1 closest to the wearer's bridge of the nose, and the top surface 102 and bottom surface 103 are the sides of lens 1 closest to the wearer's forehead and cheek, respectively. The inner surface 101, top surface 102, and bottom surface 103 of lens 1 can all be non-optical surfaces. Lens connecting portion 2 is provided on the inner surface 101 of lens 1. Specifically, the width of lens connecting portion 2 can be smaller than the width of lens 1, and lens connecting portion 2 can be connected to the top, middle, or bottom of the inner surface 101 of lens 1; lens connecting portion 2 can also have a curvature adapted to the wearer's bridge of the nose, which is not specifically limited in this disclosure.

[0064] In one exemplary embodiment of this disclosure, reference is made to Figure 8 As shown, the eyeglass frame includes a frame 3 and a nose pad 4. The frame 3 is arranged around a portion of the side of the lens 1, and the nose pad 4 is arranged adjacent to the lens connecting part 2. One lens 1 has a first hook 11 extending away from the lens connecting part 2, and the other lens 1 has a second hook 12 extending away from the lens connecting part 2. The lens connecting part 2 has a protrusion 21, the extension direction of which is perpendicular to the direction from the first hook 11 to the second hook 12. (Reference) Figures 3 to 7 As shown, where, Figure 3 The first hook 11 and the second hook 12 are shown. Figures 4 to 7 The protrusion 21 is shown, and the first hook 11 and the second hook 12 are in... Figures 4 to 7 Not shown in the image. (See reference.) Figure 8 As shown, the frame 3 has a first opening 31 and a second opening 32, and the nose bridge 4 has a recess 41; the lens body is connected to the frame, the first hook 11 cooperates with the first opening 31, the second hook 12 cooperates with the second opening 32, and the protrusion 21 cooperates with the recess 41.

[0065] refer to Figures 3 to 7 As shown, the lens body and frame are detachably connected and secured by the engagement of the first hook 11 and the first opening 31, the second hook 12 and the second opening 32, and the protrusion 21 and the recess 41. When the glasses are impacted in a certain direction, for the frame and lens body to detach, the frame needs to open to the left and right sides of the lens 1; simultaneously, the nose pad 4 and the lens connection 2 need to move away from each other, allowing the protrusion 21 to disengage from the recess 41. Since the extension direction of the protrusion 21 is perpendicular to the direction from the first hook 11 to the second hook 12, an interlock is formed in the two directions in which the frame detaches from the lens body, preventing the lens 1 from dislodging from the frame when the glasses are impacted, thus improving the quality and safety performance of the glasses.

[0066] In one exemplary embodiment of this disclosure, a first hook 11 is disposed on the top surface 102 of one lens 1, and a second hook 12 is disposed on the top surface 102 of another lens 1, with the ends of the first hook 11 and the second hook 12 extending in a direction away from each other. The first hook 11 and the second hook 12 may be symmetrical with respect to the lens connecting portion 2. In other exemplary embodiments, the first hook 11 and the second hook 12 may also be selected in various sizes or shapes for the purposes of ease of manufacturing, ease of fitting and assembling with the frame 3, and a more secure connection. This disclosure does not impose special requirements on the specific shape of the hooks, for example, as shown in the attached... Figure 3 The figure shows a specific embodiment of the shape of the first hook 11 and the second hook 12.

[0067] The lens body includes two lenses 1 and a lens connecting portion 2 connecting the two lenses 1. Specifically, the lens body can be integrally molded, that is, the two lenses 1 and the lens connecting portion 2 can be integrally molded. The lenses 1 can be made of materials with good light transmission and high mechanical strength, such as plexiglass or PET plastic. For example, for eyeglasses without myopia correction function, the lens body can be integrally injection molded from high-transparency plastic, thus having strong impact resistance. In an exemplary embodiment, the strength of the integrally injection molded lens body is approximately 60-65 MPa. Alternatively, the lens body can also be integrally injection molded, combined with a small amount of machining of the first hook 11 and the second hook 12 protrusions 21 to obtain the lens body.

[0068] In another exemplary embodiment, lens 1 may also have vision correction function. The two lenses 1 can be welded together using a plastic welding process. For example, to improve the overall strength of the lens body, in yet another exemplary embodiment, the two lenses 1 have a first insert and a second insert made of metal on adjacent sides, which are then welded together to form a lens connection portion 2. Specifically, the first insert may be located on the right side of the left lens 1, and the second insert may be located on the left side of the right lens 1. The first insert and the second insert may be austenitic stainless steel sheets, firmly connected to the left and right lenses 1 respectively, with the metal parts exposed. During the assembly of the glasses, the exposed metal parts of the first insert and the second insert are first laser welded, and then the exposed parts after welding can be covered and welded with the same plastic sheet material as the lens 1. Since the overall injection molding strength of PET plastic is approximately 60-65 MPa, while the welding strength of austenitic stainless steel can reach 350 MPa, as long as the cross-sectional area of ​​the welded joint reaches about 20% of the overall injection molding area, the connection between the left and right lenses 1 can be strengthened by the metal fitting, making the strength of the lens body basically consistent with the overall injection molding solution. Furthermore, using laser welding with metal inserts can avoid defects such as bubbles and blackening that are easily caused by simple plastic welding, improving aesthetics and preventing a decrease in lens body strength and protective capability due to these defects. In other exemplary embodiments, the first and second inserts can also be made of other high-strength alloy materials.

[0069] In one exemplary embodiment of this disclosure, reference is made to Figure 2 As shown, the optical unit 13 includes a main body 131, an inner canthus extension 132, an in-eye extension 133, and an outer canthus extension 134, all of which are integrally formed. The projection of the main body 131 along its thickness direction can be approximately elliptical. The inner canthus extension 132 protrudes towards the lens connector 2 from the side of the main body 131 closest to it. The outer canthus extension 134 protrudes away from the lens connector 2 from the side of the main body 131 furthest from it. The in-eye extension 133 is located between the inner canthus extension 132 and the outer canthus extension 134, and protrudes from the main body 131 in a direction perpendicular to the line connecting the two lenses 1. The inner corner extension 132, the middle eye extension 133, and the outer corner extension 134 expand the range of optical perspective at the inner corner of the wearer's eye, the center of vision, and the outer corner of the eye, respectively. This is consistent with human visual observation habits and helps the wearer obtain a larger field of vision.

[0070] In one embodiment, reference Figure 2As shown, the eye extension 133 can be located on the side of the main body 131 near the bottom surface 103 of the lens 1 and protrude towards the bottom surface 103 of the lens 1, thereby expanding the range of optical vision below the wearer's center of vision, which conforms to human visual observation habits. Simultaneously, the top surface 102 of the lens 1 can be relatively flat, facilitating the arrangement of the first hook 11 and the second hook 12, as well as the assembly of the frame 3 and the lens 1. In another embodiment, the eye extension 133 can also simultaneously include a portion protruding upwards, i.e., towards the top surface 102 of the lens 1, and a portion protruding downwards, i.e., towards the bottom surface 103 of the lens 1, thereby expanding the range of optical vision in both the upper and lower directions above and below the wearer's center of vision. Beyond the optical part 13, there can be a gradual transition to a thicker outer edge 14, until the edge of the lens 1, where the outer edge 14 can gradually taper to form a smooth edge of the lens 1, improving impact resistance.

[0071] Further reference Figure 9 As shown, the entire lens body can be shaped to protrude in the thickness direction of the lens 1. That is, the entire lens 1 can be arched when viewed in the thickness direction. On the one hand, it matches the curvature of the wearer's face, and on the other hand, it is also conducive to distributing the impact force to the entire lens body and frame when subjected to an impact from the direction directly facing the face, so as to achieve uniform force distribution.

[0072] In one exemplary embodiment, in the width direction of the wearer's face, the portion of the lens near the center of the face has a relatively large radius of curvature and protrudes forward; the portion of the lens near the sides of the face can have a relatively small radius of curvature and tends to bend backward towards the wearer. This can protect the wearer's side face and vulnerable areas such as the temples when facing side impacts from areas with narrow vision. Moreover, it can fit the wearer's facial shape more closely, reducing the space occupied by the glasses on the outer side of the wearer's front, making the structure of the glasses more compact, and less likely to be bumped or knocked by the external environment during the wearer's activities.

[0073] In one exemplary embodiment of this disclosure, the width of the outer edge portion 14 at the adjacent outer corner extension portion 134 can be the maximum width of the outer edge portion 14, so that the outer corner extension portion 134 has a targeted protective effect against impacts from the side of the wearer, without the need to add a protective structure such as a shield to the side; at the same time, compared with increasing the area of ​​the lens 1 as a whole, or making the lens 1 into an integrated eye mask, the solution of the exemplary embodiment of this disclosure can be more lightweight and aesthetically pleasing.

[0074] In one exemplary embodiment of this disclosure, reference is made to Figure 9As shown, the entire lens body can be a continuous curved surface protruding forward towards the face. The curvature of the lens body at the junction of lens 1 and lens connection 2 is continuous. When any part of the lens body is subjected to an external impact, the force is easily distributed in all directions in the manner of a curved arched beam, which is beneficial for resisting the damage caused by impacts from external directions. Tests have shown that the impact resistance of the lens body of this exemplary embodiment can be significantly improved. In experiments, when the lens body of this exemplary embodiment is impacted by a 6 mm diameter, 0.86 g steel ball at a speed of 45 m / s (162 km / h), lens 1 did not crack; when impacted by a 22 mm diameter, 43 g steel ball dropped from a height of 1.3 meters (equivalent speed 5 m / s, 18 km / h), lens 1 did not shatter or fail.

[0075] Furthermore, the thickness of the outer edge portion 14 near the outer corner extension portion 134 can be the maximum thickness of the outer edge portion 14. Since the outer edge portion 14 adjacent to the outer corner extension portion 134 is already at the edge of the wearer's field of vision, increasing its thickness will not have a significant impact on the wearer's field of vision. At the same time, since this part is at the edge of the wearer's field of vision, impacts from this direction are easily ignored by the wearer. Therefore, providing a thicker outer edge portion 14 at this part is beneficial to protect the wearer from damage caused by impacts from this direction.

[0076] The eyeglass frame includes a lens frame 3 and a nose pad 4. Specifically, the frame can be made of a material with better elasticity than the lens body, such as plastic, rubber, or resin. The frame can also be formed by injection molding. In one exemplary embodiment, refer to... Figure 10 As shown, a skin-friendly layer 5 can be provided on the side of the frame away from the lens connection part 2. The material of the skin-friendly layer 5 is different from the material of the nose pad 4. For example, since the nose pad 4 needs to match the lens connection part 2 through the recess 41, the material of the nose pad 4 can be a hard plastic or rubber, resin, etc., with better tensile strength and elasticity. The skin-friendly layer 5 is located on the side of the frame away from the lens connection part 2 and can be made of softer plastic or rubber, etc., with anti-allergenic properties, to improve wearing comfort. The frame and the skin-friendly layer 5 can be manufactured by multi-material injection molding, such as by co-molding or two-color injection molding, which ensures wearing comfort and also enhances the aesthetics of the frame.

[0077] The frame 3 is set around a portion of the side of the lens 1, specifically, for example, see reference. Figure 1As shown, the frame 3 surrounds and covers the top surface 102 of the lens 1. When assembling the frame and the lens body, a method similar to drawing a bow can be used: first, the first opening 31 engages with the first hook 11; then, the frame is stretched laterally towards the second hook 12, and the second opening 32 engages with the second hook 12; then, the nose bridge 4 is stretched towards the lens connecting part 2, so that the protrusion 21 and the recess 41 cooperate to fix the lens body and the frame. In other exemplary embodiments, the frame 3 may also surround and cover the bottom surface 103 of the lens 1, the outer surface opposite to the inner surface 101 of the lens 1, etc., and this disclosure does not make any special limitations on this.

[0078] In one exemplary embodiment of this disclosure, reference is made to Figure 8 As shown, the cross-sectional area of ​​the frame 3 in the part covering the top surface 102 of the lens 1 can be slightly smaller than the cross-sectional area of ​​the frame 3 in other parts, so that the local strength of the frame 3 in this part is slightly lower, but it has higher elasticity, which is beneficial to the assembly of the first hook 11 and the first opening 31, the second hook 12 and the second opening 32.

[0079] In one exemplary embodiment of this disclosure, reference is made to Figures 4 to 7 As shown, the height of the protrusion 21 near the top surface 102 of the lens 1 is different from the height of the protrusion 21 near the bottom surface 103 of the lens 1, thus making the surface of the protrusion 21 away from the lens connecting portion 2 an inclined surface. For example, in one embodiment, while the ends of the first hook 11 and the second hook 12 extend in a direction away from each other, the first hook 11 also extends towards the bottom surface 103 of the lens 1, and the second hook 12 also extends towards the bottom surface 103 of the lens 1. The height of the protrusion 21 near the top surface 102 is greater than the height of the protrusion 21 near the bottom surface 103, so that the surface of the protrusion 21 away from the lens connecting portion 2 is an inclined surface that slopes from the top surface 102 of the lens 1 towards the bottom surface 103 of the lens 1.

[0080] When the glasses are impacted from a certain direction, for the frame and lens to detach, the frame needs to open to the left and right sides of the lens 1, and the nose pad 4 needs to move away from the lens connection 2. Simultaneously, since the ends of the first hook 11 and the second hook 12 extend towards the bottom surface 103 of the lens 1, for the first hook 11 to disengage from the first opening 31 and the second hook 12 from the second opening 32, the left and right sides of the frame need to bend downwards. The recessed portion 41 on the nose pad 4, after being compressed and deformed, detaches from above the lens connection 2. Because the height of the protrusion 21 near the top surface 102 is greater than the height of the protrusion 21 near the bottom surface 103, the recessed portion 41 is obstructed by the sidewall of the protrusion 21 near the bottom surface 103 during the upward movement of the nose pad 4 relative to the lens connection 2, making it more difficult for it to detach from the protrusion 21.

[0081] In one exemplary embodiment of this disclosure, reference is made to Figures 4 to 7 As shown, the lens connecting part 2 is also provided with a groove 22, which is adjacent to the protrusion 21, and the side wall of the groove 22 near the top surface 102 is coplanar with the side wall of the protrusion 21 near the bottom surface 103. This increases the drop at the side wall of the protrusion 21 near the bottom surface 103, suppressing the tendency of the nose bridge 4 to move upward relative to the lens connecting part 2. Further, refer to... Figure 8 As shown, the nose bridge 4 may also be provided with an auxiliary protrusion 42, which is adjacent to the recess 41, and the side wall of the auxiliary protrusion 42 near the top surface 102 is coplanar with the side wall of the recess 41 near the bottom surface 103. The auxiliary protrusion 42 can cooperate with the groove 22 to enhance the fixation of the frame.

[0082] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the lens connecting part 2 is provided with a limiting groove 23, and the opening direction of the limiting groove 23 is perpendicular to the extending direction of the protrusion 21. (Reference) Figure 8 As shown, the nose bridge 4 is also provided with a limiting part 43, which cooperates with the limiting groove 23. Specifically, the opening direction of the limiting groove 23 can face the top surface 102 or the bottom surface 103 of the lens 1. For example, the shape of the limiting groove 23 can be approximately "n" shaped and open towards the top surface 102 of the lens 1. The nose bridge 4 is provided with a limiting part 43 for cooperating with the limiting groove 23. When the lens body and the frame are assembled into one piece, the limiting part 43 is locked in the limiting groove 23, which can make the connection tighter and also play a role in assisting the positioning of the lens body and the frame.

[0083] The eyeglasses also need to be secured to the wearer's face. For example, they can be secured to the wearer's face by elastic straps connecting opposite ends of the frame in this disclosure. Alternatively, the eyeglasses may also include two temples 6 respectively connected to opposite ends of the frame, which are hung on the wearer's ears by hooks 60 at the ends of the temples 6. In an exemplary embodiment of this disclosure, reference is made to... Figure 11 and Figure 12 As shown, the eyeglasses also include two temples 6 connected to opposite ends of the frame, and the temples 6 are connected to the frame 3 via a temple adjustment mechanism. The temple adjustment mechanism includes a first pivot 71, a second pivot 72, a first fork 73, and a second fork 74. The first pivot 71 and the second pivot 72 are perpendicular and fixedly connected. The first fork 73 is located on the frame 3, and the second fork 74 is located at one end of the temple 6. The first fork 73 is hinged to the first pivot 71, and the second fork 74 is hinged to the second pivot 72.

[0084] refer to Figure 11 and Figure 12As shown, the frame 3 can have an arc that adapts to the side profile of a person's head and extends backward away from the lens body. An intermediate connecting member 63 can be provided between the frame 3 and the temple 6. A first rotating shaft 71 and a second rotating shaft 72 are perpendicular to each other, respectively located at both ends of the intermediate connecting member 63, and respectively hinged to a first fork 73 and a second fork 74. By rotating the first fork 73 around the first rotating shaft 71, the vertical tilt angle of the frame and lens 1 relative to the temple 6 can be adjusted; by rotating the second fork 74 around the second rotating shaft 72, the inward and outward opening angle of the temple 6 can be adjusted. Alternatively, by rotating the first fork 73 around the first rotating shaft 71, the vertical tilt angle of the frame and lens 1 relative to the temple 6 can be adjusted; by rotating the second fork 74 around the second rotating shaft 72, the tilt angle of the frame and lens 1 relative to the temple 6 can be adjusted. This exemplary embodiment of the present disclosure, through its temple adjustment mechanism, allows the glasses to adapt to different head shapes, accommodating head size in both the height and width directions, thus increasing wearing comfort. The first rotating shaft 71 and the second rotating shaft 72 can be in the form of damping pins, which can be fixed at the corresponding angle after rotation stops. The first rotating shaft 71 and the second rotating shaft 72 can be made of metal.

[0085] Furthermore, in one exemplary embodiment, reference is made to... Figure 11 and Figure 12 As shown, the temple 6 includes a temple body 61 and a positioning sleeve 62. A second fork 74 is located at one end of the temple body 61. A positioning boss 64 can also be provided at the other end of the temple body 61 opposite to the location of the second fork 74. The positioning boss 64 is used to connect with the positioning sleeve 62. The positioning sleeve 62 has multiple positioning grooves 621 of the same size as the positioning boss 64, and the end of the positioning sleeve 62 has a hook 60 for hanging on the wearer's ear. The positioning sleeve 62 can change its relative position to the temple body 61 by cooperating with different positioning grooves 621 and positioning bosses 64. This allows the positioning sleeve 62 to be telescopically mounted on the temple body 61, thereby adjusting the length of the temple 6 to adapt to different head sizes in the front-to-back length direction and match different head shapes. Furthermore, the inner side of the temple 6, where it contacts the wearer's skin, can also have a skin-friendly layer 5 similar to the inner side of the frame. The temple 6 can also be molded using multi-material injection molding.

[0086] In addition, the positioning sleeve 62 can be detachably connected to the temple body 61. When the wearer needs to run, jump or other activities, the positioning sleeve 62 can be removed from the temple body 61 and replaced with an elastic band with positioning grooves 621 at both ends that are the same size as the positioning protrusions 64. The opposite ends of the elastic band are connected to the positioning protrusions 64 on the two temple bodies 61 respectively, which can more firmly fix the glasses on the head and prevent the glasses from falling off the head during irregular movements.

[0087] For lenses 1 with or without vision correction function, the lens body of this disclosure can be formed into the same shape, so it can be matched with the same type of frame. Therefore, the eyeglasses of this disclosure can be easily selected and replaced.

[0088] Specifically, the lens body, frame, and temples 6 can be standardized and grouped. Based on the size and shape of a person's head and face, they can be divided into multiple standardized models, and corresponding lens bodies, frames, and temples 6 can be prefabricated according to these standardized models. In addition, they can also be standardized and grouped according to appearance, color, etc., and different models of frames and temples 6 can be prefabricated.

[0089] In particular, regarding the lens body, although there is a distinction between lenses 1 with and without vision correction function, since the frame 3 is arranged around a portion of the side of the lens 1, regardless of whether the lens 1 has vision correction function or not, the lens body of this disclosure includes two lenses 1 and a lens connecting part 2 connecting the two lenses 1, and therefore can be formed into a lens body of the same shape to match standardized prefabricated frames.

[0090] For lenses 1 without vision correction function, multiple standardized, one-piece injection-molded lens bodies can be prefabricated according to the size and shape of the wearer's head and face. For lenses 1 with vision correction function, in addition to being grouped according to the size and shape of the wearer's head and face, they can be further divided into multiple groups according to the wearer's visual range, creating individual lenses 1. When myopic consumers choose lenses, they can select the corresponding individual lens 1 according to the visual acuity of their left and right eyes, and then weld the two lenses 1 together. After the lens body is formed, it can be manually fitted into the prefabricated frame, achieving a good fixing effect. Then, the prefabricated temples 6 are installed, completing the assembly of the glasses. This method avoids the need for post-purchase processing to form the required lenses 1. Because plastic welding and metal welding are easy and fast, and require simple equipment, it allows for immediate use after purchase, greatly improving the convenience of choosing glasses.

[0091] Furthermore, in some exemplary embodiments of this disclosure, since the lens body, frame, and temples 6 can all be made by injection molding, processes such as dyeing, coating, and screen printing of injection molding materials can be applied to achieve random combinations of various patterns and colors, thereby giving the glasses a fashionable characteristic.
