     Patent Literature 1 describes eyeglasses without nose pads, in which “eyeglasses without nose pads include a front portion and temple body parts attached to the front portion; auxiliary temple pieces are attached to the temple body parts; and the temple body parts and the auxiliary temple pieces are supported by the zygomatic bones and the back of the head. 
     CITATION LIST 
     Patent Literature 
     [Patent Literature 1] JP 2015-38608 A 
     SUMMARY OF THE INVENTION 
     Technical Problem 
     In general eyeglasses, the lens portion is supported in front of the eyes by applying loads to nose pads and temple tips. Excessive load from the nose pads puts a strain on the skin above the nose. 
     In the technique described in Patent Literature 1, instead of having no nose pads, the eyeglasses are supported by installing auxiliary temple pieces on the temples. However, one end of the auxiliary temple piece is located just beside the eye, and the appearance when wearing the eyeglasses is not preferable. Moreover, the temple body parts are elastically bent to open and close the eyeglasses, so the eyeglasses are supported in a form of pressing and holding onto the head from both sides, which causes a headache in a case where the elasticity is strong. Even in a case where the elasticity is not strong, a load is applied from one end of the auxiliary temple piece on the side of the eye, which causes a burden on the skin at that location. 
     In view of the situation described above, an object of the present invention is to appropriately disperse the load of eyeglasses. 
     Solution to Problem 
     In order to solve the problem described above, the eyeglasses according to one form of the present invention include: a front portion having lenses; a pair of arm portions extending substantially perpendicularly from both ends of the front portion; a pair of eyeglasses support members connected to each of the arm portions: wherein each of the pair of eyeglasses support members has a zygomatic arch contact portion that comes in contact with a temporal region so as to engage with a zygomatic arch; and a parietal bone support portion that comes in contact with a position on an outer side of the parietal bone and supports the eyeglasses from above. 
     Each of the pair of eyeglasses support members may be composed of a long, thin member having the zygomatic arch contact portion at one end and the parietal bone support portion at the other end, and extends diagonally from below to above the arm portion and from the front to the back of the head. 
     Any of the eyeglasses above, wherein the pair of eyeglasses support members may be connected to each other at each of the parietal bone supports. 
     Any of the eyeglasses above, further including connecting members that connect the arm portions and the eyeglasses support members; wherein each connecting member has a plurality of fitting portions, and one of the fitting portions and the arm portion are detachably fitted. 
     Any of the eyeglasses above, further including connecting members that connect the arm portions and the eyeglasses support members; wherein each connecting member may be rotatably provided with respect to the eyeglasses support member. 
     Any of the eyeglasses above, wherein each eyeglasses support member may have a protrusion on an upper side of the connecting member that protrudes further in a width direction than the connecting member. 
     Any of the eyeglasses above, wherein each eyeglasses support member may have a covering portion that covers at least a part of an outer surface of the connecting member. 
     Any of the eyeglasses above, wherein each arm portion may have a detachable member that fits into a fitting portion provided on the connecting member. 
     Any of the eyeglasses above, wherein each eyeglasses support member may have a hook-shaped member on a surface opposite to the zygomatic arch contact portion. 
     Any of the eyeglasses above, wherein each arm portion may have a slit extending in a longitudinal direction or a plurality of through holes continuously arranged in the longitudinal direction; and each eyeglasses support member may be fixed at an arbitrary position in a longitudinal direction of the arm portion by a fixing member penetrating through the slit or the through hole.

     DESCRIPTION OF THE EMBODIMENTS 
     Hereinafter, embodiments of the present invention will be described with reference to the drawings. 
       FIGS. 14A and 14B  are views (No. 1) illustrating an example of the appearance of conventional eyeglasses  8  without nose pads.  FIG. 14A  is a right side view of the worn eyeglasses  8 , and  FIG. 14B  is a plan view of the worn eyeglasses  8 . The eyeglasses  8  have a front portion  811  and arm portions  812 . The front portion  811  is a portion that holds the lenses, and the arm portions  812  are so-called “stems”. 
     The arm portion  812  has a temple  813  and a temple tip  814 . In typical eyeglasses with nose pads, the temple  813  and the temple tip  814  are connected in a straight line, and one end of the temple tip  814  is curved downward and is formed along the curve of the back of the ear. The temple tip  814  of the eyeglasses  8  illustrated in  FIGS. 14A, 14B  has a shape extending not only toward the rear of the attachment portion e with the temple  813  but also toward the front. 
     When viewed from above, the temple tips  814  have a curved shape along the head on both the left and right sides, and are formed so as to be in close contact with the side surface of the head. When viewed from the side, the temple tip  814  is divided into two forks at the front and rear of the attachment portion e with the Temple  813 . The front of the temple tip  814  comes in contact in the vicinity of the eye orbit so as to be secured by the zygomatic bone. Therefore, the front of the temple tip  814  extends beyond the hairline to the skin portion of the face, and the front of the temple tip  814  is visible when the face is viewed from the front. 
     In addition, the rear of the temple tip  814  extends toward the rear to the temporal bone. The load previously applied to the nose pads is distributed to the front and rear of the temple tip  814 . 
     In this embodiment, the eyeglasses  8  are supported by the temple tips  814  pressing against and holding onto the head from the left and right, so a load is applied from the front of the temple tips  814  located on the skin portion of the face, which causes a burden on that skin portion. Moreover, the front portions of the temple tips  814  are located at positions so as to be visible when looking at the face, which also hinders the appearance. 
     Furthermore, in a case where the zygomatic bone of the user does not have a shape that supports the front of the temple tips  814 , or in a case where the temple tips  814  apply weak to press against and hold onto the head, the eyeglasses  8  slide downward. On the other hand, in a case where the temple tips  814  apply a strong force to press against and hold onto to the head, there is a possibility that headaches may occur. 
       FIGS. 15A and 15B  are views (No. 2) illustrating an example of the appearance of conventional eyeglasses  9  without nose pads.  FIG. 15A  is a right side view of the worn eyeglasses  9 , and  FIG. 15B  is a plan view of the worn eyeglasses  9 . The eyeglasses  9  have a front portion  911  and arm portions  912 . The front portion  911  is a portion having lenses, and the arm portions  912  are “stems”. 
     The arm portion  912  has a temple  913  and a temple tip  914 . Similar to the temple tips  814  illustrated in  FIGS. 14A and 14B , the temple tip  914  of the eyeglasses  9  illustrated in  FIG. 15  has a shape extending not only toward the rear but also toward the front of the attachment portion f of the temple  913 . Note that the front and rear of the temple tip  914  are different from those of the eyeglasses  8  in that they are not divided into two forks. 
     Similar to the temple tip  814  in  FIGS. 14A and 14B , the front of the temple tip  914  extends to the vicinity of the eye orbit so as to be secured by the zygomatic bone, and the front of the temple tip  914  is visible when the face is viewed from the front. In addition, the rear of the temple tips  914  extend toward the rear of the temporal bones, and the eyeglasses  9  are such that by the left and right temple tips  914  pressing against and holding onto the head therebetween, the front portion  911  is supported in front of the eyes. However, as in the case of the eyeglasses  8  illustrated in  FIGS. 14A and 14B , the eyeglasses  9  may slide downward when conditions are not met. In particular, when the center of gravity of the eyeglasses  8  or the eyeglasses  9  is closer to the front portions  811  and  911 , there is a high possibility that the front portions  811  and  911  will not be supported and fall downward. 
     First Embodiment 
       FIGS. 1A and 1B  are views illustrating an example of the appearance of eyeglasses  1  according to a first embodiment.  FIG. 1A  is an example of a right side view of the eyeglasses  1 , and  FIG. 1B  is an example of a plan view of the eyeglasses  1 . The eyeglasses  1  have eyeglasses support members  100  and an eyeglasses main body portion  110 . 
     The eyeglasses main body portion  110  has a front portion  111  having lenses and a set of arm portions  112  extending substantially vertically from both ends of the front portion  111 . The front portion  111  is provided with one or more lenses. Preferably, the front portion  111  does not have nose pads. 
     The arm portions  112  have a temple  113  and a temple tip  114 . The temple  113  is made of metal, resin, or the like. The temple tip  114  is a member that comes into contact with the upper portion of the base of the outer ear, and is formed of a resin such as silicon, rubber, or the like. The temple tip  114  may be integrated with the temple  113 , and the material of the temple  113  and the temple tip  114  is not limited. 
     The eyeglasses support member  100  is a set of members connected to each arm portion  112 , and each has a zygomatic arch contact portion  101  and a parietal bone support portion  102 . As an example, the eyeglasses support member  100  is composed of a pair of long, thin members having a zygomatic arch contact portion  101  at one end and a parietal bone support portion  102  at the other end. When worn on the head, the eyeglasses support member  100  extends in a direction from below to above the arm portion  112 , and extends in a direction from the front toward the rear of the head. In addition, the eyeglasses support member  100  has a curved shape that curves inward along the head (see  FIGS. 3A to 3C ). 
     As an example, the eyeglasses support member  100  is partially or entirely formed of resin. However, the material of the eyeglasses support member  100  is not limited to this. 
     The zygomatic arch contact portion  101  is provided on the inside of the eyeglasses support member  100  (the side that comes in contact with the head) and comes in contact the temporal region. The zygomatic arch is a bone that extends substantially horizontally toward the outside of the eye orbit. The zygomatic arch contact portion  101  comes in contact with the temporal region so as to engage with the zygomatic arch. 
     The parietal bone support portion  102  is provided inside the eyeglasses support member  100  and comes in contact with an outer position of the parietal bone to support the eyeglasses  1  from above. As an example, the parietal bone support portion  102  has a surface that extends in close contact along the surface of the head (including the scalp and hair) located on the outside of the parietal bone when worn, and applies a load to the surface of the head in a direction from top to bottom. As a result, the parietal bone support portion  102  supports the eyeglasses  1  from above. 
     The eyeglasses support member  100  is connected to the temple tip  114  or the temple  113  in the vicinity of the zygomatic arch contact portion  101  or above the zygomatic arch contact portion  101 . Hereinafter, an example in which the eyeglasses support member  100  is connected to the temple tip  114  will be described. The eyeglasses support member  100  and the temple tip  114  may be rotatably or detachably connected, or may be fixed so as not to be detached or rotated. The eyeglasses support member  100  and the temple tip  114  may also be integrally molded. 
       FIG. 2  is a view illustrating an example of a perspective view of eyeglasses  1 . The pair of eyeglasses support members  100  have a left-right symmetrical shape. The eyeglasses support members  100  in this example is located on the inner side of the temple tip  114 . In  FIG. 2 , the eyeglasses support member  100  and the temple tip  114  are connected by a small screw; however, the method of connecting the eyeglasses support member  100  and the temple tip  114  is not limited to this. 
     The inner surface of the eyeglasses support member  100  may have a shape having a plurality of grooves having a non-slip function. The grooves may be provided over the entire inner surface of the eyeglasses support member  100 . In addition, comb teeth for securing the eyeglasses support member  100  to the hair may be provided on all or a part of the inner surface of the eyeglasses support member  100 . The comb teeth may be provided so as to stand erect on the inner surface of the eyeglasses support member  100 . The comb teeth may also be provided so as to extend from the rear side surface or the front side surface of the eyeglasses support member  100  toward the rear or front of the user. 
     Moreover, the eyeglasses support member  100  does not have to have a linear shape as illustrated in  FIG. 1A  when viewed from the side, and may have a wavy shape in the front-rear direction. In addition, the eyeglasses support member  100  may have a jagged shape having a plurality of corners such as saw blades in the front and rear. Furthermore, the eyeglasses support member  100  may be shaped like an elongated ring when viewed from the side. 
     By increasing the contact area with the surface of the head as compared with the case of a linear shape, it is possible to prevent the eyeglasses support member  100  from becoming displaced from the surface of the head. Moreover, by increasing the degree of freedom in the shape, the design becomes more diverse and the design is improved. 
       FIGS. 3A to 3C  are views illustrating an example of the appearance of eyeglasses when worn on the head.  FIG. 3A  is an example of a right side view of the eyeglasses  1  when worn on the head, and  FIG. 3B  is an example of a plan view of the eyeglasses  1  when worn on the head.  FIG. 3C  is an example of a front view of the zygomatic arch contact portion  101  of the eyeglasses support member  100  located on the left side of the person wearing the eyeglasses  1 .  FIG. 3C  illustrates only a cross section of the temple tip  114 , and the other parts of the temple tip  114  are not illustrated. 
     As illustrated in  FIG. 3  (A), as a result of coming in contact with the temporal region so as to engage with the zygomatic arch, the zygomatic arch contact portion  101  is located further on the rear side than the general hairline. In addition, the eyeglasses support member  100  extends at an incline in a direction from below to above the arm portion  112  and from the front toward the rear of the head. Furthermore, as is evident from  FIGS. 3  (A) and  3  (C), the eyeglasses support member  100  in this example is located further on the inner side (head side) than the temple tip  114 . The eyeglasses support member  100  in this example has a recess  115  having front and rear openings on the outer surface, and the eyeglasses support member  100  and the temple tip  114  are connected by fitting a part of the temple tip  114  into the recess  115 . 
     Note that the eyeglasses  1  according to the present embodiment have eyeglasses support members  100  extending to the parietal bone, so that the center of gravity is located at the rear side as compared with the eyeglasses having no eyeglasses support members  100 . With this configuration, the front portion  111 , which tends to apply a load because of having the lenses, is appropriately held in front of the eyes. This is especially useful in a case of eyeglasses  1  that do not have node pads. 
       FIGS. 4A to 4C  are views illustrating an example of the appearance of eyeglasses  1  when worn on the head.  FIG. 4A  is a right side view of another example of eyeglasses  1  when worn on the head, and  FIG. 4B  is a plan view of another example of eyeglasses  1  when worn on the head.  FIG. 4C  is another example of a front view of the zygomatic arch contact portion  101  of the eyeglasses support member  100  located on the left side of the person wearing the eyeglasses  1 .  FIG. 4C  illustrates only the cross section of the temple tip  114  as in the case of  FIG. 3C , and the other parts of the temple tip  114  are not illustrated. 
     In this example, the eyeglasses support member  100  has a recess  115  on the inner side surface, and the eyeglasses support member  100  and the temple tip  114  are connected by fitting a part of the temple tip  114  into the recess  115 . In order to maintain an appropriate distance between the temple tip  114  and the head, the zygomatic arch contact portion  101  of the eyeglasses support member  100  may have a shape bulging further inward than illustrated in  FIG. 4  (C). 
     First Modification 
       FIGS. 5A and 5B  are views illustrating an example of the appearance of an eyeglasses support member  100  in a first modification.  FIG. 5A  is an example of a view as seen from the front of the eyeglasses support member  100  located on the left side of the person wearing the eyeglasses  1  in the first modification.  FIG. 5B  is a diagram illustrating a usage state of the eyeglass support member  100  illustrated in  FIG. 5A . Hereinafter, points that differ from the embodiments described above will be described. Note that unless otherwise specified, each of the pair of eyeglass support members  100  has a left-right symmetrical shape. Moreover, the x-axis indicates the left-right direction of the head, the y-axis indicates the vertical direction of the head, and the z-direction indicates the front-back direction of the head. The same applies to other figures as well. 
     The eyeglasses support member  100  has a through hole  103  and the temple  113  or the temple tip  114  penetrates through the through hole  103 . In the example illustrated in  FIGS. 5A and 5B , the temple tip  114  penetrates through the through hole  103 . The through hole  103  may have a plurality of recesses on the inner peripheral surface thereof, and the temple tip  114  may have a plurality of protrusions on the outer peripheral surface thereof, each of which may into the recess. 
     By fitting together the recesses of the through hole  103  and the protrusions of the temple tip  114 , the rotation angle of the eyeglasses support member  100  about the axis of the temple tip  114  is determined. In other words, taking an axis parallel to the z-axis illustrated in  FIG. 5  (A) or  FIG. 5  (B) (in other words, an axis corresponding to the temple tip  114 ) to be a p-axis, the rotation angle of the eyeglasses support member  100  about the p-axis is determined. In a case where the eyeglasses  1  are worn on the head, and in a case where the wearability is not preferable such as when there is insufficient adhesion between the parietal bone support portion  102  and the head, the rotation angle of the eyeglasses support member  100  may be adjusted by fitting the protrusions of the temple tip  114  into other recesses of the through hole  103 . Note that it is also possible for the through hole  103  to have protrusions, and the temple tip  114  to have recesses. 
     Note that the eyeglasses  1  are not limited to this structure as long as the rotation angle of the eyeglasses support member  100  about the axis of the temple tip  114  can be fixed. For example, the structure may be such that the through hole  103  has claws on the inner peripheral surface that are hooked on the protrusions of the temple tip  114 , which prevents rotation in one direction (for example rotation to the right in  FIG. 5A  or  FIG. 5B ), and allows rotation in the opposite direction. 
     Second Modification 
       FIG. 6  is a view illustrating an example (No. 1) of a perspective view of eyeglasses  1  in a second modification. In this modification, the pair of eyeglasses support members  100  are connected to each other by their respective parietal bone support portions  102 . In other words, the eyeglasses support member  100  is a long, thin member that has a zygomatic arch contact portion  101  on one end that comes in contact with temporal region on the right side and a zygomatic arch contact portion  101  on the other end that comes in contact with the temporal region on the left side. The eyeglasses support member  100  has a parietal bone support portion  102  near the center. 
       FIG. 7  is a view illustrating an example (No. 2) of a perspective view of eyeglasses  1  in a second modification. As illustrated in  FIG. 7 , the eyeglasses support member  100  in the second modification may have one or a plurality of protrusions  104  on the inner side surface. The contact between the protrusions  104  and the hair makes it easier for the eyeglasses support member  100  to be secured near the outer side of the parietal bone. 
     Note that the eyeglasses support member  100  of the eyeglasses  1  in the second modification does not have to have a linear shape when viewed from the side, and needless to say, may have a wavy shape in the front-rear direction, or may have a shape in which there is plurality of corner portions such as saw blades in the front-rear direction. 
     Second Embodiment 
       FIGS. 8A and 8B  are views illustrating an example of the appearance when eyeglasses  2  according to a second embodiment are worn on the head.  FIG. 8A  is an example of a right side view when the eyeglasses  2  according to this second embodiment are worn on the head, and  FIG. 8B  is an example of a plan view when the eyeglasses  2  according to this second embodiment are worn on the head. Hereinafter, points that differ from the first embodiment described above will be described. 
     The eyeglasses  2  have eyeglasses support members  200  and an eyeglasses main body portion  210 . The eyeglasses main body portion  210  has a front portion  211  and arm portions  212 , and the arm portions  212  have temples  213  and temple tips  214 . The eyeglasses support member  200  is different from the first embodiment in that, together with having a zygomatic arch contact portion  201  and a parietal bone support portion  202 , also has a connecting member  203 . 
     In the example illustrated in  FIGS. 8A and 8B , the connecting member  203  is provided on the outer side of the eyeglasses support member  100 . Note that the connecting member  203  in  FIGS. 8A and 8B  has an elliptical shape when viewed from the side of the user; however, the shape of the connecting member is not limited to this. The shape may also be circular or polygonal. 
       FIGS. 9A and 9B  are views for explaining in detail the eyeglasses support member  200  according to this second embodiment.  FIG. 9A  is an example of a view of the eyeglasses support member  200  and the arm portion  212  located on the left side of the user when worn, as viewed from the left side, and  FIG. 9B  is a front view of a part of the eyeglass support member  200 . 
     The connecting member  203  has a plurality of fitting portions  204 , and any one of the fitting portions  204  and the arm portion  212  are detachably fitted to each other. The connecting member  203  is provided so as to be able to rotate with respect to the eyeglasses support member  200 . Presuming that the axis parallel to the x-axis illustrated in  FIGS. 9A and 9B  is a q-axis, the eyeglasses support member  200  is able to rotate about the q-axis with respect to the connecting member  203 . In other words, the arm portion  212  is fixed by wearing the eyeglasses  2 , and the connecting member  203  that fits with the arm portion  212  is also fixed in the same manner; however, it becomes possible for the eyeglasses support member  200  to rotate about the q-axis with respect to the connecting member  203 . 
     The connecting member  203  has a plurality of fitting portions  204  having different heights. The connecting member  203  illustrated in  FIGS. 9A and 9B  is located on the outer side of the zygomatic arch contact portion  201 , and has three fitting portions  204  that are recessed outward. The fitting portion  204  has a recess in substantially the center when viewed from the front that is recessed more than the other portions. That shape is referred to as the fitting portion  204 A, and the shape of the fitting portion  204  will be described later. Note that in the example illustrated in  FIGS. 9A and 9B , the fitting portion  204  is provided on the surface of the outer side of the connecting member  203 ; however, the fitting portion  204  may also be provided on the surface of the inner side (the surface on the head side) of the connecting member  203 . The same applies to the modifications illustrated below. 
     Moreover, the eyeglasses support member  200  in this second embodiment has a protrusion  205  on the upper side of the connecting member  203  that protrudes in the width direction (the left-right direction of the user, or in other words, the x-axis direction in  FIG. 9B ) from the connecting member  203 . In a case where there is a gap between the main body portion of the eyeglasses support member  200  and the connecting member  203 , the protrusion  205  prevents hair from entering the gap. In addition, the protrusion  205  prevents hair from entering between the fitting portion  204  and the temple tip  214 . 
       FIGS. 10A and 10B  are views for explaining an example of a fitting portion  204 A in this second embodiment.  FIG. 10A  is a front view illustrating a part of the eyeglasses support member  200  and the cross section of the connecting member  203  located on the left side of the user when worn. The fitting portion  204 A extends in the z direction, and both ends thereof are open. Moreover, the fitting portion  204 A has a recess  207 A. The recess  207 A is a portion further recessed on the bottom surface of the fitting portion  204 A and having a recessed shape with respect to the connecting member  203 . On the other hand, the temple tip  214  has a protrusion  215 . The protrusion  215  fits into the recess  207 A to further strengthen the connection between the connecting member  203  and the temple tip  214 . 
       FIG. 10B  is an example of a plan view of the eyeglasses main body portion  210 . The protrusion  215  of the temple tip  214  of the eyeglasses main body portion  210  protrudes inward so as to fit into the recess  207 A, and extends to the front and rear. The protrusion  215  may be detachable with respect to the temple tip  214 . In that case, the protrusion  215  may be integrally molded with, for example, a resin cylinder that is removable from the temple tip  214 . 
     As described above, the fitting portion  204 A may also be provided on the surface of the inner side of the connecting member  203 . In that case, the protrusion  215  of the eyeglasses  2  protrudes outward. 
     The surface on the inner side of the temple tip  214  is brought into contact with the upper and lower edges of the opening portion in the x direction of the fitting portion  204 A, and by applying a constant force, the temple tip  214  is fitted with and fixed to the fitting portion  204 A. Note that it is desirable that the dimension s in the height direction of the opening portion of the fitting portion  204 A is smaller than the dimension tin the height direction of the inner portion of the fitting portion  204 A and the dimension u in the height direction of the temple tip. 
     The temple tip  214  may be fitted with each of a plurality of fitting portions  204 A having different heights, so the temple tip  214  may be fitted by selecting a fitting portion  204 A having a preferable height at the time of fitting. In addition, the fitting portion  204 A extends in the z direction, so the position of the temple tip  214  (in other words, the arm portion  212 ) may be adjusted by shifting as necessary. 
     Note that instead of having the fitting portion  204 , the connecting member  203  may have one or a plurality of through holes as illustrated in  FIGS. 5A and 5B . The through hole of the connecting member  203  extends in the z direction in  FIGS. 5A and 5B  in the same manner as that illustrated in  FIGS. 5A and 5B . By causing the arm portion  212  to penetrate through the through hole, not only the rotation angle about the q-axis illustrated in  FIGS. 9A and 9B , but also the rotation angle about the arm portion  212  may be adjusted. 
       FIGS. 11A to 11B  are views (No. 1) illustrating an example of a modification of the eyeglasses support member  200  according to a second embodiment.

     In a case where there is a gap between the connecting member  203  and the main body portion of the eyeglasses support member  200 , the gap is covered by the covering portion  206 , and it is possible to prevent hair from entering the gap. Moreover, the fitting portion  204  is covered, so not only is hair or the like prevented from entering the fitting portion, a neat impression is also given to the appearance. 
       FIGS. 12A to 12D  are views (No. 2) illustrating an example of a modification of the eyeglasses support member  200  according to a second embodiment. 
     Third Modification 
       FIG. 12A  is a view illustrating a third modification of the eyeglasses support member  200  according to the second embodiment. The connecting member  203  in the third modification has a fitting portion  204 B. The fitting portion  204 B differs from the fitting portion  204 A in that it does not have a recess on the bottom surface. The temple tip  214  of general eyeglasses  2  may be fitted into the fitting portion  204 B. 
     Fourth Modification 
       FIG. 12B  is a view illustrating a fourth modification of the eyeglasses support member  200  according to the second embodiment. The connecting member  203  in the fourth modification has a plurality of hole-shaped fitting portions  204 C. Moreover, the eyeglasses  2  in the fourth modification has attachments  216  on the arm portions  212 . As an example, the attachment  216  is removable with respect to the arm portion  212 . The installation method for installing the attachment  216  on the arm portion  212  is not limited. The attachment  216  has a plurality of protrusions  215 B. 
     The arm portion  212  and the connecting member  203  are connected by fitting a part of the plurality of protrusions  215 B in the fitting portions  204 C. As an example, the attachment  216  and the protrusions  215 B are integrally molded with resin and fitted to the fitting portions  204 C of the connecting member  203  formed of resin. Moreover, the fitting portions  204 C and the protrusions  215 B are formed so as to engage with each other. As an example, the protrusions  215 B have a trapezoidal cross-sectional shape with the dimension in the height direction of the tip end being greater then the base, and the fitting portions  204 C have a shape that fits into the protrusions  215 B having the shape described above. 
     Third Embodiment 
       FIGS. 13A to 13C  are views illustrating an example of the appearance of eyeglasses  3  according to a third, fourth and fifth embodiment.  FIG. 13A  is an example of a right side view of the eyeglasses  3  according to a third embodiment. The eyeglasses support member  300  of the eyeglasses  3  in the third embodiment have recesses  320  on the outer side. The recess  320  may be through holes. 
     An accessory r having a protrusion may be connected to the recess  320 .

The accessory r is, for example, a decorative accessory and may decorate the eyeglasses support member  300 . 
     Fourth Embodiment 
       FIG. 13B  is a diagram showing an example of using the eyeglasses  3  in a fourth embodiment.  FIG. 13B  illustrates a part of the eyeglasses support member  300  and the eyeglasses  3  that are located on the left side when viewed from the user. A set of eyeglasses support members  300  have hook-shaped members  321  that are pointed upward and toward the rear on the surface of the opposite side of the zygomatic arch contact portions  301 . As illustrated in  FIG. 13B , the hook-shaped member  321  can secure the elastic band portions of a mask. 
     In a conventional mask, the cloth portion may be applied to the nose and mouth by putting two elastic band portions on the left and right ears, but the elastic force of the elastic band portions may hurt the ears. By attaching the elastic band portions to the hook-shaped members  321  in the first modification, the mask may be worn without putting a burden on the ears. 
     Fifth Embodiment 
       FIG. 13C  is an example of a right side view of the eyeglasses  3  according to a fifth embodiment. The eyeglasses support member  300  in the second modification is a set of hollow long, thin members, and by opening and closing a part thereof, contents may be put into the hollow portion. 
     Moreover, the eyeglasses support member  300  in the second modification has holes  322 , a barb  323 , and a tube  324 . The holes  322  are holes formed in the outer surface of the eyeglasses support member  300 , and air inside the eyeglasses support member  300  can be taken in and out. The barb  323  is provided on the inner portion of the eyeglasses support member  300  to prevent the contents from falling downward.  FIG. 13C  illustrates how the barb  323  holds dry ice d placed inside the eyeglasses support member  300 . 
     The tube  324  is a hollow tube, one end of which is connected to the hollow portion of the eyeglasses support member  300 . The other end of the tube  324  extends to a position reaching the user&#39;s mouth. The user can breathe through the tube  324  and the eyeglasses support member  300  by holding the end of the tube  324 . 
     When dry ice d is put inside the eyeglasses support member  300  and air is blown from the tube  324 , CO 2  vaporized from the dry ice d is ejected from the hole  322 . This is especially useful when desiring to create an interesting appearance. 
     In addition, for example, the gas emitted from the contents of the eyeglasses support member  300  may be sucked in. For example, chopped tobacco can be placed inside and inhaled. Furthermore, for example, by adding a solid chemical, the vaporized chemical can be inhaled. 
     Sixth Embodiment 
       FIG. 16  is a view illustrating an example of a perspective view of eyeglasses  4  according to a sixth embodiment. The eyeglasses  4  have eyeglasses support members  400  and an eyeglasses main body portion  410 . The eyeglasses main body portion  410  has a front portion  411  and arm portions  412 . In the arm portions  412  illustrated in  FIG. 16 , the temple tip and the temple are integrated; however, as in the other embodiments described above, the temple tip and the temple may be connected to form the arm portion  412 . The eyeglasses support members  400  have a zygomatic arch contact portion  401  and a parietal bone support portion  402 , as in the other embodiments described above. 
     The arm portions  412  in this sixth embodiment have a fixing member  431 , a slit  432 , a plurality of contact members  433 , and one or a plurality of through holes  434 . The slit  432  is provided so as to extend in the longitudinal direction of the arm portion  412 . 
     The eyeglasses support members  400  are fixed at an arbitrary position in the longitudinal direction of the arm portion  412  by the fixing member  431  penetrating the slit  432 . In other words, by changing the fixed position by the fixing member  431 , the position of the eyeglasses support members  400  in the front-back direction (z direction) with respect to the eyeglasses main body portion  410  may be adjusted. 
     In addition, the fixing member  431  fixes the eyeglasses support member  400  to the arm portion  412  by penetrating through the through hole  434  of the eyeglasses support member  400  and the slit  432 . In a case where the eyeglasses support member  400  has a plurality of through holes  434 , the vertical position of the eyeglasses support member  400  with respect to the eyeglasses main body portion  410  may be adjusted by the fixing member  431  penetrating through different through holes  434  and fixing the eyeglasses support member  400 . 
     Moreover, the eyeglasses support member  403  has a plurality of contact members  433  protruding in the width direction (x-axis direction in  FIG. 16 ) on the inside thereof. The contact members  433  protrudes further than the protrusion height in the width direction (inside) of the fixing member  431 , and prevents the fixing member  431  from coming into contact with the skin. In this example, the eyeglasses support member  400  is fixed by the fixing member  431  having a screw head on the inside; however, preferably the contact members  433  are provided on both sides of the screw head (or in other words, the through holes  434 ) so that the screw head does not come into direct contact with the skin. 
     Note that the contact members  433  illustrated in  FIG. 16  are long, thin members that extend along the longitudinal direction of the eyeglasses support member  400 ; however, the shape of the contact members  433  is not limited to this, as long as the contact members  433  protrude so as to prevent the fixing member  431  from coming in contact with the skin. For example, the contact members  433  may be a plurality of continuous protrusions connected to both sides of the through holes  434 . In this case, the contact members  433  may be configured so that a pair of protrusions face each other via one through hole  434  for one or a plurality of the through holes  434  of the eyeglasses support member  400 . 
     Note that in the eyeglasses support member  403 , instead of providing the contact members  433 , recesses having a depth for embedding the screw head may be provided on the peripheral edges of the through holes  434 . In this case, preferably recesses are provided so that the inner surface of the eyeglasses support member  403  and the surface of the screw head are flush with each other as much as possible. 
     Note that the arm portion  412  may have a plurality of through holes that are continuously arranged in the longitudinal direction instead of the slit  432 . By inserting the fixing member  431  through different through holes, the eyeglasses support member  400  may be fixed at an arbitrary position in the longitudinal direction of the arm portion  412 , as in the case of using the slit  432 . 
     Moreover, the eyeglasses support member  400  may have a protrusion that penetrates the slit  432  instead of the through holes  434 . The eyeglasses support member  400  may be fixed to the arm portion  412  by using a nut-shaped or cap-shaped member having a diameter larger than the width of the slit  432  with respect to the protrusion penetrating the slit  432 . 
     Note that as illustrated in  FIG. 16 , the eyeglasses support member  400  may be fixed to the inner side of the arm portion  412  or may be fixed to the outer side of the arm portion  412 . 
       FIG. 17  is a view for explaining an example of a fixing member  431 . The fixing member  431  has a screw  435 , washers  436  and  438 , a cover part  437 , and a nut  439 . The cover part  437  is a member that covers a part of the arm portion  412 . As illustrated in  FIGS. 16 and 17 , when the eyeglasses support member  400  is fixed to the inside of the arm portion  412 , the screw  435  is inserted from the inner side of the eyeglasses support member  400  via the washer  436  and through the through hole  434 , the slit  432 , and the cover part  437  in that order. The eyeglasses support member  400  is fixed to the arm portion  412  by placing the washer  438  over the tip of the screw  435  that has been inserted through the through hole of the cover part  437  and then tightening the nut  439 . 
       FIG. 18  is a view illustrating an example of a right side view of a part of the eyeglasses  4  according to a sixth embodiment. In this figure, the notations for the washer  438  and the nut  439  are omitted. The slit  432  penetrates through the structure so that the position of the eyeglasses support member  400  in the front-back direction (z direction) with respect to the arm portion  412  may be adjusted. 
     Note that in the eyeglasses  4  according to the sixth embodiment, preferably the center of gravity of the eyeglasses  4  comes near the connecting portion between the eyeglasses support member  400  and the arm portion  412 . Compared to eyeglasses having a center of gravity in the vicinity of the front portion  411 , the eyeglasses  4  are well balanced when worn on the head, and the eyeglasses  4  may be stably supported on the head. 
     First Modification 
       FIG. 19  is a view illustrating an example of a perspective view of the eyeglasses  4  in a first modification of a sixth embodiment. The eyeglasses support members  400  in this modification have a plurality of contact members  440  ion the inner side thereof. The contact members  440  have a plurality of protrusions  441  that are continuously arranged in the longitudinal direction of the eyeglasses support member  400 . 
     Similar to the above-mentioned contact members  433 , the contact members  440  protrude further in the width direction than the protrusion height of the fixing member  431  in order to prevent the fixing member  431  from touching the skin. The protrusions  441  are continuously arranged in the longitudinal direction of the eyeglasses support member  400  in order to prevent the eyeglasses support member  400  and the zygomatic arch contact portion  401  from being displaced. As illustrated in  FIG. 19 , for example, the protrusions  441  have a semicircular shape when the eyeglasses  4  are viewed from the front, and by engaging with the skin and hair near the temples, it is possible to prevent the eyeglasses support member  400  from moving in the vertical direction and in the front-back direction. 
       FIG. 20  is a view illustrating an example of a right side view of a part of the eyeglasses  4  in a first modification of this sixth embodiment. The slit  432  in this modification is different from the sixth embodiment (see  FIG. 18 ) in that it extends to the temple portion. Note that the length of the slit  432  is not limited to the examples shown in  FIGS. 18 and 20 , and the slit  432  may extend to the vicinity of the end (right end in  FIG. 20 ) opposite to the front portion  411  of the arm portion  412 , for example. 
     Second Modification 
       FIG. 21  is a view illustrating an example of a perspective view of the eyeglasses  4  in a second modification of this sixth embodiment. The eyeglasses support members  400  in this modification have opening portions  422  and decorative members  460 . The opening portion  422  is one or more holes drilled in the outer surface of the eyeglasses support member  400  and is connected to a cavity inside the eyeglasses support member  400  and is able to allow air to flow in and out of the cavity. In other words, the opening portion  422  has the same function as the holes  322  of the fifth embodiment (see  FIG. 13C ) described above. 
     Moreover, the eyeglasses support member  400  in this modification has one or a plurality of decorative members  460 . The decorative member  460 , in at least in part thereof, has a curved shape along the user&#39;s head. The decorative member  460  illustrated in  FIG. 21  has the shape of a leaf, and the vicinity of the main vein is curved inward along the head. 
     Note that the decorative member  460  illustrated in  FIG. 21  is connected to the outer surface of the eyeglasses support member  400  and is provided so as to extend toward the rear of the user. However, the connection position of the decorative member  460  to the eyeglasses support member  400  is not limited to this, and may be, for example, the rear side surface, the front side surface, or the inner side surface of the eyeglasses support member  400 . The decorative member  460  may be provided so as to extend toward the front of the user. 
       FIG. 22  is a view for explaining the eyeglasses support member  400  in a second modification of this sixth embodiment. This figure is an example of a view of a part of the eyeglasses  4  in a second modification of this sixth embodiment as viewed diagonally toward the right from the rear. 
     The decorative member  460  illustrated in  FIG. 22  has an appropriate thickness and is integrated so as to bite into the eyeglasses support member  400 . With this configuration, the contact surface with the head can be widened and friction is generated, so that the eyeglasses support member  400  may be prevented from shifting. Moreover, the load of the eyeglasses  4  exerts an outward force on the decorative member  460 , and with this configuration the strength of the decorative member  460  increases. 
     Note that the accessory r in the third embodiment illustrated in  FIG. 13A  may function as the decorative member  460  in this example by being configured to come into contact with the head. 
       FIG. 23  is a view for explaining the inside of the eyeglasses support member  400  in a second modification of the sixth embodiment. The eyeglasses support member  400  has a tubular cavity  450  in the inner portion thereof. The cavity  450  has one or a plurality of opening portions  422  that open to the surface on the outer side of the eyeglasses support member  400 , and the air in the inner portion is ventilated through the openings  422 . 
     The eyeglasses support member  400  illustrated in  FIG. 23  has four opening portions  422 , and two opening portions  422  are provided near the zygomatic arch contact portion  401  and near the lower part of the eyeglasses support member  400 . In addition, the other two opening portions  422  are provided on the surface of the outer side of the eyeglasses support member  400  near the crown of the head. The cavity  450  is substantially U-shaped and connects to each of the opening portions  422 . For example, as in the fifth embodiment (see  FIG. 13C ), a hollow tube (not illustrated) extending to the mouth of the user is connected to the lower opening portions  422  of the eyeglasses support member  400 , making it possible to breathe through the cavity  450  and the tube. 
     Note that by putting contents inside the tube, the user can suck in the gas emitted from the contents and discharge the gas from the opening portions  422 , as in the fifth embodiment. 
     Furthermore, the cavity  450  in  FIG. 22  is not connected to the through holes  434  for fixing the eyeglasses support member  400  to the arm portion  412 , and the gas inside the cavity  450  is not produced from the through hole  434 . However, the cavity  450  and the through holes  434  may be connected. 
     As described above, the eyeglasses according to the present embodiment by having eyeglasses support members, the load of the eyeglasses can be appropriately distributed on the contact surface between the zygomatic arch contact portion and the temporal region, the contact surface between the parietal bone support portion and the parietal bone, and the contact surface between the temple tip and the ear. Moreover, the eyeglasses can be supported from above by the parietal bone support portion, so the burden on the side surface of the head can be reduced as compared with the conventional technique of supporting the eyeglasses from only the left and right side surfaces of the head. 
     In other word, in a case where the support member extends to the vicinity of the zygomatic bone, design restrictions are unavoidable, such as making the support member a smooth shape in order to reduce the burden on the skin of the face. The eyeglasses are supported by pressing against and holding onto the head, so when uneven portions are added to the support members so that the eyeglasses do not slide down, not only will marks be left when the eyeglasses are removed, but there is also a possibility that the skin of the face will be damaged unexpectedly. In addition, it is necessary to consider the burden on the skin of the face because of sweating at the contact locations with the support members. 
     In the eyeglasses according to the present embodiment, the zygomatic arch contact portion does not extend to the vicinity of the eye, so the degree of freedom in shape is increased. For example, even when the zygomatic arch contact portion is provided with irregularities in order to prevent the zygomatic arch contact portion from sliding downward, the zygomatic arch contact portion is located at a less conspicuous place, so that the effect on the appearance is small. 
     In particular, in the present embodiment, the location where the zygomatic arch contact portion comes in contact is close to the position where a hairpin or the like is fastened, so the size and thickness of the hair ornament can be adopted. Even when sweating, the influence on the appearance can be reduced as compared with the case where the support member comes into contact with the skin of the face. 
     Although embodiments and modifications according to the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are included. For example, an example of the above-described embodiment has been described in detail for the sake of clarity of the present invention, and the present invention is not limited to an invention having all the configurations described here. Moreover, it is possible to replace a part of the configuration of one example of a certain embodiment with the configuration of another example. In addition, it is also possible to add the configuration of another example to the configuration of one example of one embodiment. Furthermore, it is possible to add, delete or replace a part of the configuration of one example of each embodiment with another configuration.
