Description

  The present invention relates to sunglasses with a degree that is excellent in design, lightweight, and capable of changing appearance.

  In recent years, there has been an increasing need for sunglasses with excellent design properties. For example, various sunglasses with excellent design properties are commercially available, such as sunglasses curved with a large curvature toward the front along the shape of the face. In recent years, sunglasses that can be superposed on prescription glasses are commercially available so that nearsighted and presbyopic people who use prescription glasses can use sunglasses while using prescription glasses. . However, when sunglasses are superposed on prescription eyeglasses, the design of the sunglasses and prescription eyeglasses is impaired, and the weight of the eyeglasses as a whole increases, resulting in discomfort and fatigue to the user.

Therefore, for the purpose of solving such a problem, the sunglasses described in Patent Document 1 and the glasses described in Patent Document 2 have been proposed. The sunglasses and glasses described in these publications are configured such that a sunglass lens with no opening formed inside is fixed to the frame, and a lens with a degree is fitted into the opening of the sunglasses lens. Yes. Such sunglasses and glasses can be used as sunglasses when a user views an object through a sunglasses lens, and can be used as graded glasses by looking at an object through a graded lens.

  However, since the sunglasses and eyeglasses described in the above document have the sunglasses lens fixed to the frame, the sunglasses lens is replaced, and the user's preference and TPO (Time, Place, Occasion) There is a problem that it is not possible to change the appearance according to.

  The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide sunglasses with a degree that is excellent in design, lightweight, and capable of changing the appearance.

  In order to solve the above-mentioned problems, the present invention provides a frame connected to a pair of left and right temples, and a detachable attachment to the frame, as defined in claim 1 of the utility model registration claim. A flexible sunglasses lens having an opening formed therein, and a lens with a degree fitted to the opening of the sunglasses lens, and at least in the vicinity of the fitting part of the lens with the degree, The sunglasses with degrees are characterized in that the front surface of the lens with degrees is substantially flush.

  The sunglasses with the degree of the present invention has a configuration in which the degree lens is fitted into the opening of the sunglasses lens, so there is no need to superimpose the lens with the degree lens. It is possible to avoid the problem that the design is impaired by overlapping the glasses. In addition, since there is no need for such superposition, it is possible to avoid an increase in weight due to superposition. Furthermore, since the sunglasses with a degree of the present invention are detachably attached to the frame, the appearance can be changed by replacing the sunglasses lens. In addition, since the sunglasses with the degree of the present invention is substantially flush with the front surface of the sunglasses lens and the front surface of the degree lens in the vicinity of the fitting part of the degree lens, there is no difference in level between the sunglasses lens and the degree lens. Is visually recognized as being integrally formed, and thus the appearance is good.

  As a specific configuration for fitting the prescription lens to the opening portion of the sunglasses lens, any one of the outer peripheral edge of the prescription lens and the inner peripheral edge of the opening portion as in claim 2 of the utility model registration claim It is possible to adopt a configuration in which a convex portion is provided on one side and a concave portion that fits the convex portion is provided on either the outer peripheral edge of the lens with degree or the inner peripheral edge of the opening. .

  According to such a configuration, by fitting the convex portion and the concave portion, the prescription lens can be reliably fitted to the opening.

  Preferably, as in claim 3 of the utility model registration claim, the convex portion is partially provided on either the outer peripheral edge of the prescription lens and the inner peripheral edge of the opening, and / or The said recessed part can be set as the structure provided in any one of the outer periphery of the said lens with a degree, and the inner periphery of the said opening part.

  According to such a preferable configuration, since the concave portion and the convex portion are partially provided, a part of the inner peripheral edge of the sunglasses lens and a part of the outer peripheral edge of the prescription lens are fitted. Thus, if it is set as the structure which only a part fits, compared with the structure which the whole fits, it will become difficult to apply high stress locally with respect to a prescription lens. Therefore, according to such a preferable configuration, it is possible to prevent the prescription lens from being broken or cracked due to high local stress.

  Further, as a specific configuration for securely fitting the prescription lens through the opening, as described in claim 4 of the utility model registration claim, the outer periphery of the prescription lens and the inner periphery of the opening are convex. A concave portion is provided on the outer peripheral edge of the prescription lens, and the concave portion is fitted to the convex portion provided on the inner peripheral edge of the opening portion. The outer periphery of the prescription lens is provided on the inner peripheral edge of the opening portion. The structure provided with the recessed part fitted to the convex part provided in the periphery can be mentioned.

  According to such a configuration, the fitting between the convex portion provided on the prescription lens and the concave portion provided on the sunglasses lens, and the concave portion provided on the prescription lens and the convex portion provided on the sunglasses lens. By fitting, the lens with degree can be securely fitted through the opening.

  Preferably, as in claim 5 of the utility model registration claim, the convex portion is partially provided on the outer peripheral edge of the prescription lens and the inner peripheral edge of the opening, and / or the concave portion is It can be set as the structure provided partially in the outer periphery of the said lens with a degree, and the inner periphery of the said opening part.

  According to such a preferable configuration, since the concave portion and the convex portion are partially provided, a configuration in which the concave portion and the convex portion are provided on the entire outer peripheral edge of the prescription lens and the inner peripheral edge of the sunglasses lens. As compared with the above, it is difficult to apply high stress locally to the prescription lens. Therefore, according to such a preferable configuration, not only can the prescription lens be securely fitted to the opening, but the prescription lens can be broken or cracked due to local high stress. Can be prevented.

  Further, as a specific configuration of the sunglasses lens, as in claim 6 of the utility model registration claim, the sunglasses lens includes a pair of left and right rim portions each having an opening formed therein, and the pair of left and right rim portions. And a pair of bridge parts integrally formed with the pair of left and right rim parts, and the pair of left and right rim parts and the bridge part are configured to be detachable integrally with the frame. Is possible.

  According to such a configuration, since the rim portion and the bridge portion are detachable as a unit, the sunglasses lens can be easily attached and detached.

  Further, as another specific configuration of the sunglasses lens, as in claim 7 of the utility model registration claim, the sunglasses lens includes a pair of left and right rim portions each having an opening formed therein, and the pair of left and right lenses. The rim portions may be detachable from the frame independently of each other.

  According to such a configuration, the pair of left and right rim portions are independently detachable, so that each rim portion can be replaced independently. Therefore, for example, the combination of the colors and shapes of the left and right rim portions can be freely changed, and the appearance of the prescription sunglasses can be finely changed.

  The sunglasses with the degree of the present invention has a configuration in which the glasses with the degree are fitted into the opening of the sunglasses lens, so it is not necessary to superimpose the lens with the degree lens, and it is equivalent to normal sunglasses. It is possible to have a good design. In addition, since it is not necessary to superimpose the sunglasses lens and the lens with a degree, the problem of an increase in weight can be avoided and the weight can be reduced. Furthermore, since the sunglasses lens is detachably attached to the frame, the appearance can be changed by replacing the sunglasses lens.

(Embodiment 1)
Hereinafter, with reference to the accompanying drawings, a sunglasses 1 with a degree according to an embodiment of the present invention will be described. FIG. 1A is a front view of the prescription sunglasses 1, and shows a state in which a sunglasses lens 3 fitted with prescription lenses 4 is attached to the frame 2 (see FIG. 1B). (B) is a plan view thereof.

  The sunglasses with degree 1 includes a frame 2 connected to a pair of left and right temples 7, a flexible sunglasses lens 3 that is detachably attached to the frame 2, and has an opening formed inside, and a sunglasses lens 3. And a lens 4 with a degree fitted in the opening.

  As shown in FIG. 1B, the sunglasses lens 3 is formed in a thin plate shape curved with a predetermined curvature toward the front (in the direction of arrow X in FIG. 1B) along the shape of the face. . The material of the sunglasses lens 3 is not particularly limited, but a flexible material such as polycarbonate can be used.

  2A is a front view of the sunglasses lens 3, and FIG. 2B is a cross-sectional view taken along the line AA in FIG. 2A. The sunglasses lens 3 includes a pair of left and right rim portions 31 each having an opening 30 formed therein, and a pair of left and right rim portions 31, and a bridge portion formed integrally with the pair of left and right rim portions 31. The pair of left and right rim portions 31 and the bridge portion 32 are configured to be detachable as a unit with respect to the frame 2. A convex portion 30b formed along the inner peripheral edge 30a is provided on the inner peripheral edge 30a of the opening 30 of each rim portion 31. The convex portion 30b may be provided on the entire circumference of the inner peripheral edge 30a or may be provided partially. In the present embodiment, as shown in FIG. 2A, the convex portion 30b is partially provided at four locations on the upper, lower, left, and right sides of the inner peripheral edge 30a. In addition, when providing the convex part 30b partially, the position of the inner periphery 30a in which the convex part 30b is provided is not specifically limited, For example, it is two places on the upper and lower sides of the inner periphery 30a, or right and left. Also good.

  Furthermore, the sunglasses lens 3 according to the present embodiment includes a mounting portion that is mounted on the frame 2. The mounting portion includes a magnetized portion 33 that is magnetically attached to the frame 2 and an engaging portion 34 that is engaged with the frame 2. The magnetized portion 33 is formed by fitting a magnetic material such as a magnet or stainless steel into a hole drilled in the sunglasses lens 3. The magnet and the magnetic material are exposed on both the front surface and the rear surface of the sunglasses lens 3. In the present embodiment, the magnetized portion 33 is formed outside the opening 30 of each of the left and right rim portions 31 as shown in FIG. As described above, when the magnet or magnetic material used for the magnetized portion 33 is exposed on the rear surface of the sunglasses lens 3, the rear surface of the sunglasses lens 3 can be strongly magnetized on the front surface of the frame 2. . In addition, as long as the rear surface of the sunglasses lens 3 can be strongly magnetically attached to the front surface of the frame 2, the magnet or magnetic material used for the magnetic attachment portion 33 may not be exposed on the rear surface of the sunglasses lens 3. As a case where the magnetic attachment can be performed firmly without exposing the magnet or the magnetic material to the rear surface of the sunglasses lens 3, for example, the magnetic attachment between the sunglasses lens 3 and the frame 2 is performed using a strong magnet. Cases. In such a case, the design of the rear surface of the sunglasses lens 3 may be improved by covering the rear surface side of the magnet or magnetic material used for the magnetized portion 33 with a decorative member or the like.

  Moreover, if the magnet or the magnetic material is exposed on the front surface of the sunglasses lens, the design of the front surface of the sunglasses lens 3 may be deteriorated. In order to avoid this, instead of fitting a magnet or magnetic material into the hole drilled in the sunglasses lens 3, the magnet or magnetic material is adhered to the rear surface of the sunglasses lens 3 with an adhesive or the like. The wearing part 33 may be formed. When a magnet or a magnetic material is bonded to the rear surface of the sunglasses lens 3, it is not necessary to make a hole in the sunglasses lens 3, so that the magnetized portion 33 can be formed relatively easily. Note that the position and number of the magnetized portions 33 are not particularly limited, and can be determined in consideration of ensuring the user's field of view and design.

  On the other hand, in the present embodiment, the engaging portion 34 is constituted by a notch cut upward from the lower portion of the bridge portion 32 as shown in FIG. The position and number of the engaging portions 34 formed are not particularly limited, and can be determined in consideration of securing the user's field of view, designability, and the like, similarly to the magnetically attached portion 23.

  3A is a front view of the prescription lens 4, and FIG. 3B is a cross-sectional view taken along the line BB of FIG. 3A. As shown in FIG. 3A, the prescription lens 4 is provided with a concave portion 40b formed along the outer peripheral edge 40a on the outer peripheral edge 40a. The concave portion 40b is formed in a shape that can be fitted to the convex portion 30b provided on the inner peripheral edge 30a of the opening 30 described above. In addition, the recessed part 40b does not need to be provided in the perimeter of the outer periphery 40b, and should just be provided in the position corresponding to the convex part 30b at least. For example, as in the present embodiment, when the convex portions 30b are provided at four locations on the upper, lower, left and right sides of the inner peripheral edge 30a of the opening 30, the concave portions 40b are provided at least on the upper, lower, left and right sides of the outer peripheral edge 40a. That's fine. In addition, the kind of lens 40 with a degree is not specifically limited, Even if it is a sunglasses lens with a degree, the lens with a normal transparent degree may be sufficient. Further, the degree-equipped lens 4 that is fitted to the opening 30 of each of the left and right rim parts 31 does not have to have the same degree, color, and the like. For example, the degree-equipped lens 4 that is fitted to the left and right openings 30. The combination of can be in accordance with TPO and user preference.

  FIG. 4 is a front view of the sunglasses 1 with the degree in which the sunglasses lens 3 is detached from the frame 2. The frame 2 includes an outer frame 21, a connecting member 22, and a mounting portion. The outer frame 21 has a shape corresponding to the outer peripheral edge of the sunglasses lens 3 and is curved with a curvature corresponding to the sunglasses lens 3 as shown in FIG. Although this curvature is not specifically limited, In this embodiment, the curvature whose curvature radius is 80-150 mm is employ | adopted. Curvature with a radius of curvature of 80-150mm is the size used for frames with 6-curve lenses used for sports sunglasses, etc. and lenses with large curvatures called 8-curve lenses. In addition, the curvature is larger than the curvature (curvature radius: 250 to 450 mm) employed in a normal spectacle frame.

  The connecting member 22 connects the upper and lower portions of the central portion of the outer frame 21 in the left-right direction. The mounting portion is configured to mount the sunglasses lens 3. In this embodiment, the mounting portion includes a magnet 23 that is magnetically attached to the sunglasses lens 3, and a locking portion 24 that is engaged with the sunglasses lens 3. Yes. The magnet 23 is fixed to the outer frame 21 and supported at a position corresponding to the magnetized portion 33 of the sunglasses lens 3. In the present embodiment, the magnetized portion 33 is formed on the outer side (the left and right ends of the sunglasses lens 3) of the left and right rim portions 31 of the sunglasses lens, so that the magnet 23 is located on the inner side of the outer frame 21. It is supported at the left and right ends. As described above, the magnet 23 is supported at a position corresponding to the magnetized portion 33, so that the sunglasses lens 3 and the outer frame 21 can be magnetized, and the sunglasses lens 3 is attached to the outer frame 21 by this magnetizing. It can be attached to the frame 2 in close contact with the frame 2. Therefore, it is possible to maintain an excellent design of the entire sunglasses 1 with prescription. In the case where a magnet is used for the magnetized portion 33, the magnet 23 is set so that the direction of the magnetic pole is in a direction attracting the magnetized portion 33 to each other. Further, when a magnet is used for the magnetized portion 33, it is possible to use a magnetic material instead of the magnet 23.

  On the other hand, as shown in FIG. 5, the locking portion 24 is configured by a substantially L-shaped member in side view that can be engaged with a notch constituting the engaging portion 34. In the present embodiment, the substantially L-shaped member is attached to the lower part of the central portion in the left-right direction of the outer frame 21 so as to protrude forward of the outer frame 21. In addition, as long as the structure of the latching | locking part 24 is a structure which can be engaged with the engaging part 34, it is not specifically limited.

  As shown in FIG. 4, the end pieces 5 are formed on the left and right ends of the outer frame 21 of the frame 2. In the present embodiment, the armor 5 is formed as an integral part of the frame 2. Each of the left and right arms 5 is connected to the temple 7 via a hinge structure 6 (see FIG. 1B). Further, a pair of left and right pads 8 are attached to the lower part of the outer frame 21 slightly outside the central portion in the left-right direction.

  In the sunglasses 1 with the degree having the above configuration, the fitting of the lens 4 with the degree to the opening 30 of the sunglasses lens 3 and the attachment of the sunglasses lens 3 to the frame 2 will be described. First, the fitting of the prescription lens 4 to the opening 30 of the sunglasses lens 3 will be described. The prescription lens 4 can be fitted into the opening 30 of the sunglasses lens 3 by pushing the prescription lens 4 into the opening 30. That is, as described above, since the sunglasses lens 3 has flexibility, when the prescription lens 4 is pushed into the opening 30, the opening 30 is expanded by the outer peripheral edge 40 a of the prescription lens 4. Then, when the concave portion 40b of the prescription lens 4 is pushed to the position where the convex portion 30b is provided, the opening 30 tries to return to the original size, and as shown in FIG. 6, the convex portion 30b and the concave portion 40b Are fitted, and the opening 30 and the lens with degree 4 are fitted by this fitting.

  When the opening 30 and the prescription lens 4 are fitted, the front surface of the sunglasses lens 3 and the front face of the prescription lens 4 are substantially flush with each other in the vicinity of the fitting portion of the prescription lens 4. Specifically, the vicinity of the fitting site is the vicinity of the outer peripheral edge 40a of the lens 4 with a degree and the vicinity of the inner peripheral edge 30a of the sunglasses lens 3. Further, the front surface of the sunglasses lens 3 and the front surface of the lens with degree 4 are surfaces that are located in front of the sunglasses with degree 1 (in the direction of arrow Y in FIG. 6). As described above, since the front surface of the sunglasses lens 3 and the front surface of the prescription lens 4 are substantially flush with each other, no step is generated in the vicinity of the fitting portion of the prescription lens 4 and the sunglasses lens 3 and the prescription lens 4 are formed. Since it is visually recognized as being integrally formed, the appearance of the prescription sunglasses 1 is good.

  Further, when removing the prescription lens 4 from the opening 30, the prescription lens 4 may be pushed forward or behind the sunglasses lens 3. Since the sunglasses lens 3 is flexible, when the prescription lens 4 is pushed out, the opening 30 is expanded by the outer peripheral edge 40a of the prescription lens 4 and the fitting between the convex portion 30b and the concave portion 40b is released. As a result, the lens 4 with the degree is removed from the opening 30.

  Next, attachment of the sunglasses lens 3 to the frame 2 will be described. The sunglasses lens 3 is attached to the frame 2 by bringing the lower rear surface of the sunglasses lens 3 into contact with the upper front surface of the outer frame 21 of the frame 2 and shifting the sunglasses lens 3 downward with respect to the outer frame 21. And the outer peripheral edge of the sunglasses lens 3 are overlapped. As described above, since the magnet 23 is in a position corresponding to the magnetized portion 33, when the outer peripheral edge of the sunglasses lens 3 and the frame 2 overlap, the magnet 23 and the magnetized portion 33 are in contact with each other, and the magnet 23 and the magnetized portion are in contact with each other. 33 is magnetically attached. Moreover, the notch which comprises the engaging part 34 fits into the substantially L-shaped member which comprises the latching | locking part 24 from upper direction by shifting the outer periphery of the sunglasses lens 3 below, and superimposing on the outer frame 21, As a result, the sunglasses lens 3 is supported by the locking portion 24 from below. By supporting the sunglasses lens 3 from below, the sunglasses lens 3 is prevented from slipping down.

  On the other hand, the removal of the sunglasses lens 3 from the frame 2 can be performed by a procedure reverse to the above-described mounting. That is, the operation can be performed by shifting the sunglasses lens 3 upward with respect to the frame 2 and separating the sunglasses lens 3 from the front surface of the outer frame 21.

  In addition, since the fitting of the prescription lens 4 and the opening 30 of the sunglasses lens 3 is performed by fitting the convex portion 30b and the concave portion 40b, the prescription lens 4 is securely attached to the opening 30. Can be fitted.

  Furthermore, in this embodiment, since the convex part 30b is partially provided in the inner periphery 30a of the opening part 30 as mentioned above, a part of the inner periphery 30a of the opening part 30 and the outer periphery 40a of the prescription lens 4 are provided. A part of is fitted. As described above, when only a part of the inner peripheral edge 30a of the opening 30 and the outer peripheral edge 40a of the lens 4 with the degree are fitted, a locally high stress is higher than that of the whole of the fitted parts. It is difficult to apply to the attached lens 4, and therefore, the attached lens 4 can be prevented from being chipped or cracked by applying high stress locally.

  Moreover, as shown in FIG. 6, the convex part 30b and the recessed part 40b of the sunglasses 1 with a degree which concern on this embodiment are provided in the center part of the inner periphery 30a and the outer periphery 40a, and the longitudinal cross-sectional shape is formed in a rectangular shape. However, the position and shape in which the convex portion 30b is provided are not particularly limited, and the position and shape in which the concave portion 40b is provided are as long as they can be fitted to the convex portion 30b. It is not limited in. For example, the vertical cross-sectional shape of the convex portion 30b can be a triangle such as a right triangle or an isosceles triangle, or a semicircle. FIG. 7 is a vertical cross-sectional view in the vicinity of an inner peripheral edge 30a provided with a convex portion 30b having a right-angled triangular cross section and an outer peripheral edge 40a provided with a concave portion 40b that can be fitted to the convex portion 30b. FIG. 7A is a longitudinal sectional view when the convex portion 30b is provided from the front end portion of the inner peripheral edge 30a (portion located in the front (arrow Y direction) when wearing the sunglasses 1 with degree) to the central portion. FIG. 7B is a longitudinal sectional view when the convex portion 30b is provided over the entire front and rear direction of the inner peripheral edge 30a. The convex portion 30b shown in FIG. 7B can be formed, for example, by simply cutting the inner side of the sunglasses lens 3 in a straight line obliquely with respect to the surface thereof, so that the convex portion shown in FIG. 30b can be provided relatively easily even in the case of the sunglasses lens 3 having the thin rim portion 31 having a thickness of 1 mm or less in the front-rear direction.

  Further, when the prescription lens 4 is inserted into or removed from the sunglasses lens 3, the prescription lens 4 may be stressed, and the prescription lens 4 may be broken or broken. The convex portion 30b may be formed of a member having relatively low rigidity. For example, as shown in FIG. 8, a protruding member formed of a material having a relatively low rigidity so that a concave groove 30 d is provided at a position where the convex portion 30 b of the inner peripheral edge 30 a is provided, and the concave groove 30 d protrudes from the inner peripheral edge 30 a. 30e is fitted. A portion protruding from the inner peripheral edge 30a of the protruding member 30d forms a convex portion 30b. In this way, by using a relatively low-rigidity material for the protruding member 30e, it is possible to prevent the prescription lens 4 from being chipped or cracked during fitting or removal.

  Furthermore, although the degree sunglasses 1 according to the present embodiment is provided with the convex portion 30b on the inner peripheral edge 30a and the concave portion 40b on the outer peripheral edge 40a, the sunglasses with degree according to the present invention is provided on the outer peripheral edge 40a. It is also possible to adopt a configuration (see FIG. 9) in which the convex portion 30b is provided and the inner peripheral edge 30a is provided with the concave portion 40b. Also in this configuration, the position and shape in which the convex portion 30b is provided are not particularly limited, and the position and shape in which the concave portion 40b is provided are not limited as long as they can be fitted to the convex portion 30b. . In FIG. 9 (a), a convex portion 30b having a right triangle shape, which is formed so as to extend outward as it goes rearward of the outer peripheral edge 40a, is provided at the front (arrow Y direction) portion of the outer peripheral edge 40a. The longitudinal cross-sectional view of the vicinity of the inner periphery 30a and the outer periphery 40a is shown. FIG. 9 (b) shows the inner peripheral edge 30a when the right-angled triangular convex part 30b formed so as to extend outwardly toward the rear of the outer peripheral edge 40a is provided at the rear part of the outer peripheral edge 40a. The longitudinal cross-sectional view of the vicinity of the outer periphery 40a is shown. As shown in FIG. 9B, when the convex portion 30 b is formed so that the amount extending outwardly toward the rear of the outer peripheral edge 40 a is small, the prescription lens 4 is moved backward from the front side of the opening 30. When pushed in the direction opposite to the arrow Y, the opening 30 gradually widens and the prescription lens 4 can be easily fitted into the opening 30. FIG. 9C shows a longitudinal sectional view of the vicinity of the inner peripheral edge 30a and the outer peripheral edge 40a when the substantially isosceles triangular convex part 30b is formed in the front part of the outer peripheral edge 40a. (D) shows the longitudinal cross-sectional view of the vicinity of the inner periphery 30a and the outer periphery 40a when the substantially semicircle-shaped convex part 30b is formed in the front part of the outer periphery 40a.

  As a configuration capable of more reliably fitting the prescription lens 4 and the opening 30 of the sunglasses lens 3, the convex portion 40 c is formed on the outer peripheral edge 40 a of the prescription lens 4 and the inner peripheral edge 30 a of the opening 30. , 30b, and a concave portion 40b that fits with the convex portion 30b provided on the inner peripheral edge 30a of the opening 30 is provided on the outer peripheral edge 40a of the prescription lens 4, and the inner peripheral edge 30a of the opening 30 is provided with The structure (refer FIG. 10) provided with the recessed part 30c fitted to the convex part 40c provided in the outer periphery 40a of the lens 4 with a degree can be mentioned. The convex portion 40c is provided along the outer peripheral edge 40a similarly to the concave portion 40b, and the concave portion 30c is provided along the inner peripheral edge 30a similarly to the convex portion 30b.

  According to such a configuration, when the prescription lens 4 is pushed into the opening 30, not only the fitting of the concave portion 40 b of the prescription lens 4 and the convex portion 30 b of the sunglasses lens 3 but also the convex portion 40 c of the prescription lens 4. And the concave portion 30 c of the sunglasses lens 3 are also fitted, so that the prescription lens 4 can be more reliably fitted to the opening 30.

  As described above, even in the configuration in which the concave portion and the convex portion are provided on both the outer peripheral edge 40 a of the prescription lens 4 and the inner peripheral edge 30 a of the sunglasses lens 3, these convex portions and concave portions are provided on the outer peripheral edge of the prescription lens 4. 40a and the inner periphery 30a of the sunglasses lens 3 may be provided on the entire circumference or may be provided partially. When partially provided, as described above, the opening 30 and the prescription lens 4 are fitted only at a part of the inner peripheral edge 30a and the outer peripheral edge 40a, and a locally high stress is given to the preferential lens. 4, it is possible to prevent the prescription lens 4 from being chipped or cracked.

  Further, as shown in FIG. 11A, the lens 4 with a degree may be provided with a drop-off preventing portion 41 that is received near the inner peripheral edge 30 a of the opening 30. The drop-off prevention part 41 is provided so as to extend outward from a rear part (a direction opposite to the arrow Y direction in FIG. 11B) of the outer peripheral edge 40 a of the prescription lens 4. In order to fit the lens with degree 4 provided with the drop-off prevention part 41 into the opening 30, the lens with degree 4 is pushed forward from the rear side of the opening 30. As shown in FIG. 11 (b), when the prescription lens 4 is fitted into the opening 30, the drop-off prevention part 41 is received in the vicinity of the inner peripheral edge 30 a, so that the drop-off prevention part 41 pushes in excessively at the time of fitting. In other words, it is possible to prevent the prescription lens 4 from dropping out to the front of the opening 30.

  In addition, as described above, in the sunglasses 1 with the degree according to the present embodiment, the opening 30 and the lens 4 with the sunglasses lens 3 are fitted to the convex part 30b and the concave part 40b, or the convex part 30c and the concave part 40c. It has been explained that it is detachable by fitting.
