[0026] To further illustrate the embodiments, the present disclosure is provided with the accompanying drawings. These drawings form a part of the present disclosure and are included to further explain the embodiments and to demonstrate how to make and use the same. With reference to these drawings, those skilled in the art will appreciate other ways of implementing the present disclosure and its equivalents. The elements in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the embodiments. Like reference numerals are generally used to refer to like elements throughout.

[0027] Reference is made to Figure 1 , which shows a schematic view of the impact-resistant eyewear of the first embodiment of the present disclosure. Figure 1 The appearance of the impact-resistant eyewear 1, such as the shape, size, proportion, etc., is only for example and is not intended to limit the present disclosure. The impact-resistant eyewear 1 mainly includes a wearing unit 10 and a lens unit 12. The materials of the wearing unit 10 and the lens unit 12 are not limited, but preferably made of materials with good toughness to improve the impact resistance of the impact-resistant eyewear 1. Toughness is a comprehensive property including mechanical strength and ductility. The wearing unit 10 is assembled with the lens unit 12, and the wearing unit 10 can be pivotably or non-pivotably assembled with the lens unit 12 as needed. The former is assembled by, for example, pivoting, twisting, snapping, etc., the latter is, for example, made by integrally forming the wearing unit 10 and the lens unit 12 to be firmly assembled, or assembled by structures such as buckles, perforations, etc. to assemble the wearing unit 10 in the form of a headband with the lens unit 12, etc. The present embodiment exemplarily pivots the wearing unit 10 and the lens unit 12 to assemble the two, so that the user can pivot the wearing unit 10 to become a folded state convenient for storage, or pivot the wearing unit 10 again to become an unfolded state convenient for use.

[0028] In the present embodiment, the wearing unit 10 includes two wearing parts 11 to facilitate wearing the impact-resistant eyewear 1 on the user's face. The wearing parts 11 exemplified herein are two temples extending a predetermined length along a first linear direction, which can be hung over the user's ears to wear the impact-resistant eyewear 1. In other embodiments, the wearing parts 11 can be designed in different structures or include more elements to improve the stability, comfort, convenience, safety, etc. of wearing, such as: the wearing parts 11 can be designed as a headband with adjustable length, which has good stability and comfort, or has additional auxiliary supports to improve safety, and the ends of the temples or headband are preferably symmetrically assembled on the opposite sides of the impact-resistant eyewear 1.

[0029] The lens unit 12 includes at least one assembly portion 13 and at least one impact-resistant lens 14, in this embodiment, two impact-resistant lenses 14 are taken as an example, and the assembly portion 13 is exemplified as a full-frame lens frame, but the present application is not limited thereto. The impact-resistant lens 14 can be a polarized lens with a curved surface effect, such as a toric lens, and the shape, size, and proportion of the impact-resistant lens 14 are only examples, and the present application is not limited thereto. The assembly portion 13 and at least a portion of the assembly portion 13 corresponding to the outer side of the impact-resistant lens 14 can be assembled by fitting, clamping, locking, or the like, so that the impact-resistant lens 14 is fixed to the assembly portion 13, thereby the impact-resistant lens 14 is symmetrically assembled with the wearing unit 10 by the assembly portion 13. In other words, in this embodiment, when the two impact-resistant lenses 14 are fixed to the assembly portion 13 and assembled with the wearing unit 10, the two impact-resistant lenses 14 and the wearing unit 10 as a whole have a symmetric center line. Each impact-resistant lens 14 includes at least one curved surface region extending along a second linear direction and a third linear direction, respectively, and the curved surface region is curved with different curvatures in the second and third linear directions. The curved surface region is preferably a toric surface. The second linear direction is, for example, a horizontal direction perpendicular to the aforementioned symmetric center line, and the third linear direction is, for example, a vertical direction parallel to the aforementioned symmetric center line. It should be noted that the aforementioned first, second, and third linear directions can be straight line directions, curved line directions, or other linear directions, and are not limited to Figure 1By having different curvatures in different linear directions, such as: a smaller curvature in the second linear direction than in the third linear direction, or a larger curvature in the second linear direction than in the third linear direction, etc., the curvature of the curved area of the impact-resistant lens 14 in different directions can be controlled, thereby increasing the coverage and flexibility of the impact-resistant lens in the inner, outer, or upper, lower lateral directions, and improving the range and tolerance of the impact-resistant glasses against impact. Preferably, the curvature of the curved area in the second linear direction is smaller than its curvature in the third linear direction, thereby adjusting the coverage and flexibility of the impact-resistant lens 14 corresponding to the inner, outer, or upper, lower lateral contour of the user's eye when the impact-resistant glasses 1 are worn on the user's face, to better block impacts or splashes from the inner, outer, or upper, lower lateral directions, and to provide the user with a better range of vision and a more comfortable feeling without pressure. More preferably, the radius of curvature of the curved area in the second linear direction is between 87-74mm, and 82-86mm is preferred, and the curvature converted by the optical constant Φ523 divided by the radius of curvature is about 6-7 degrees (curve), and 6.081-6.378 degrees is preferred; the radius of curvature of the curved area in the third linear direction is between 174-137.6mm, and 174-149mm is preferred, and the curvature converted by the optical constant Φ523 divided by the radius of curvature is about 3-3.8 degrees, and 3-3.5 degrees is preferred. The impact-resistant glasses 1 can be industrial safety glasses, and the impact-resistant performance under a certain impact speed, such as an impact speed of 42-725 FT / S, can meet the ANSI standard, CSA standard, AS / NZS standard, EN standard or military standard.

[0030] Please refer to Figure 2 , which shows a schematic view of an impact-resistant lens of a second embodiment of the present application. As Figure 2 shown in the figure, the impact-resistant lens 24 of the present embodiment can be assembled in an impact-resistant glasses, and its outer contour can be designed as required, without limitation, and the shape of the impact-resistant glasses it is suitable for is also not limited. The impact-resistant lens 24 includes at least a hyperbolic-shaped curved area extending along a first linear direction, a second linear direction, respectively, within an upper boundary line B1, a lower boundary line B2, a left boundary line B3 and a right boundary line B4. The impact-resistant lens 24 of the present embodiment can be taken as a hyperbolic lens. Please note that the aforementioned first and second linear directions can be straight line directions, curved line directions or other linear directions, and are not limited to Figure 2The curved surface region is curved in the first and second linear directions with different curvatures CI and C2, and CI can be less than C2 or CI can be greater than C2. In this embodiment, CI is less than C2. The curved surface region is preferably a double curved surface. In detail, the curved surface region can include a first extending section Al and two second extending sections A2. The second extending sections A2 are adjacent to the inner side and the outer side of the first extending section Al in the first linear direction. The first extending section Al is adapted to correspond to the blocking of a front impact from the impact-resistant lens 24, and the second extending sections A2 are adapted to correspond to the blocking of an inner side impact and an outer side impact from the impact-resistant lens. Since the curved surface region of the impact-resistant lens 24 is curved in the first and second linear directions with different curvatures, the coverage and the toughness of the impact-resistant lens 24 in the first or second linear direction are increased, thereby improving the range and the tolerance of the impact-resistant eyewear against impacts.

[0031] Preferably, as exemplified in this embodiment, the first and second linear directions can be perpendicular to each other, and can be horizontal and vertical directions, respectively. The reference coordinate axes are based on the impact-resistant eyewear to which the impact-resistant lens 24 is applied. The curvature CI of the curved surface region in the horizontal direction between the upper boundary line B1 and the lower boundary line B2 is different from the curvature C2 of the curved surface region in the vertical direction between the left boundary line B3 and the right boundary line B4. For example, the curvature CI of the curved surface region in the horizontal direction can be less than the curvature C2 of the curved surface region in the vertical direction, or the curvature CI of the curved surface region in the horizontal direction can be greater than the curvature C2 of the curved surface region in the vertical direction, and so on. In this embodiment, the curvature CI of the curved surface region in the horizontal direction is greater than the curvature C2 of the curved surface region in the vertical direction, i.e., the curvature in the horizontal direction is greater than the curvature in the vertical direction, so that the curved surface region of the impact-resistant lens 24 has a greater curvature in the horizontal direction, thereby fitting the profile of the user's side face and increasing the coverage and the toughness of the impact-resistant lens 24 to the profile of the user's eye, thereby improving the range and the tolerance of the impact-resistant eyewear against impacts from the side, and providing the user with a wider field of vision and a more comfortable feeling without pressure. Preferably, the radius of curvature of the curved surface region in the horizontal direction is between 87 and 74 mm, and is preferably between 82 and 86 mm. The curvature calculated by dividing the optical constant Φ523 by the radius of curvature is about 6 to 7 cal, and is preferably about 6.081 to 6.378 cal. The radius of curvature of the curved surface region in the vertical direction is between 174 and 137.6 mm, and is preferably between 174 and 149 mm. The curvature calculated by dividing the optical constant Φ523 by the radius of curvature is about 3 to 3.8 cal, and is preferably about 3 to 3.5 cal. More preferably, the impact-resistant lens 24 can meet the ANSI standard, the CSA standard, the AS / NZS standard, the EN standard, or the military standard at a certain impact speed, such as an impact speed of 42 to 725 FT / S.

[0032] However, in another embodiment, when the curved surface region of the impact-resistant lens has a curvature C1 in the horizontal direction that is less than a curvature C2 in the vertical direction, the curved surface region of the impact-resistant lens can exhibit a greater degree of curvature in the vertical direction, thereby covering the contours of the user's face above and below, and increasing the coverage and resilience of the impact-resistant lens 24 to the contours of the user's eyes above and below. The impact-resistant lens of this embodiment is equivalent to the impact-resistant lens 14 of the first embodiment rotated ninety degrees, in which the curved surface region includes a first extension section adapted to correspond to blocking impacts from a front direction of the impact-resistant lens, and a second extension section adjacent to the upper side and the lower side of the first extension section, adapted to correspond to blocking impacts from an upper side direction and a lower side direction of the impact-resistant lens.

[0033] Please refer to Figure 2 、 Figure 3 , Figure 3 a schematic view showing an impact-resistant eyewear according to a third embodiment of the present application. Figure 3 The shape, size, and appearance of the impact-resistant eyewear 2 of FIG. 1 are merely exemplary and are not intended to limit the present application.

The materials of the wearing unit 20 and the lens unit 22 are not limited, but preferably are made of materials having good toughness to improve the impact resistance of the impact-resistant eyewear 1, in which toughness is a comprehensive property including mechanical strength and ductility. The wearing unit 20 is assembled with the lens unit 22, and can be pivotably or non-pivotably assembled with the lens unit 22 as needed. The former is assembled by, for example, pivoting, twisting, snapping, or the like, and the latter is made by, for example, integrally forming the wearing unit 20 and the lens unit 22 to be firmly assembled, or assembling the wearing unit 20 and the lens unit 22 in the form of a headband by means of a clasp, a hole, or the like. In this embodiment, the wearing unit 20 and the lens unit 22 are pivotally assembled, so that the user can pivot the wearing unit 20 to be in a folded state for easy storage, or pivot the wearing unit 20 to be in an unfolded state for easy use, as needed.

[0034] In the present embodiment, the wearing unit 20 includes two wearing parts 21 to facilitate wearing the impact-resistant glasses 2 on the face of the user. In the present embodiment, the wearing parts 21 are two temple stems respectively extending along a first linear direction for a predetermined length, which are hung over the ears of the user to wear the impact-resistant glasses 2. In other embodiments, the wearing parts 21 can be designed in different configurations or include more elements to improve the stability, comfort, convenience, safety, etc. of wearing, such as: the wearing parts 21 can be designed as a headband with adjustable length, which has good stability and comfort, or has additional auxiliary supports to improve safety, and the two ends of the temple stems or the headband are preferably symmetrically assembled on the opposite sides of the impact-resistant glasses 2.

[0035] The lens unit 22 includes at least one assembling part 23 and at least one impact-resistant lens 24, which is a second embodiment of the impact-resistant lens 24 in the present embodiment. The impact-resistant lens 24 is specially designed to have a single-piece lens with a single-piece outer edge contour, and the assembling part 23 is exemplified as two connecting members connected between the wearing parts 21 and the assembling part 23, but the present application is not limited thereto. The assembling part 23 and at least a portion of the impact-resistant lens 24 corresponding to the assembling part 23 on the outside can be assembled by fitting, clamping, locking, etc. so that the impact-resistant lens 24 is fixedly arranged on the assembling part 23, thereby the impact-resistant lens 24 is symmetrically assembled with the wearing unit 20 by the assembling part 23. In other words, in the present embodiment, the two impact-resistant lenses 24 are fixedly arranged on the assembling part 13 and assembled with the wearing unit 20, the two impact-resistant lenses 24 have a symmetric center line as a whole, and the wearing parts 21 such as temple stems, headbands, etc. are respectively assembled on the opposite sides of the symmetric center line, so that the two impact-resistant lenses 24 and the wearing unit 20 have a symmetric center line as a whole.

[0036] The nose pad unit 25 is assembled with the lens unit 22, which is attached to the user's nose to wear the impact-resistant glasses 2, thereby improving the stability.

[0037] As described above, since the second embodiment of the impact-resistant lens 24 is used here, the coverage range of the user's eye contour and the toughness here are improved, and the range and tolerance of the impact-resistant glasses 2 against lateral impact are improved. However, the first embodiment of the impact-resistant lens 14 or other impact-resistant lenses can also be used in the present embodiment, and the present application is not limited thereto.
