The inner part forms the eyeglasses thereby. Then, the hanging foot is hooked on the ear so that the nose pad 1 is in contact with the side of the nose, and by holding the eyeglass at a predetermined position on the face, the field of view can be obtained through the lens. The nose pad 1 of the present embodiment configured as described above constitutes the surface 3 of the pad body 2 by combining a plurality of curved surfaces 4 to 8 having the same curvature and the same curvature, and the curvature of the curved surfaces 4 to 8 is set to substantially The surface of the nose matches the sputum. When the surface 3 of the pad body 2 is brought into contact with the side surface of the nose, the load from the eyeglasses is not concentrated on a part of the surface 3 of the pad body 2, and the load can be dispersed throughout the surface 3 of the pad body 2. Therefore, pain does not occur due to the shape trace of the pad body 2 remaining on the surface of the nose, and a comfortable wearing feeling can be obtained for a long time, and it can be used for a long time. φ Further, since the peripheral portion of the pad body 2 is formed by the curved surfaces 5, 6, and 8 having a smaller curvature than the other portions, the peripheral portion of the pad body 2 can be prevented from hanging on the surface of the nose, and a comfortable wearing can be obtained. sense. Moreover, since the pad body 2 is externally shaped, the left and right asymmetry is formed centering on the center line 35 of the core 40, so that the surface 3 of the pad body 2 does not contact the surface of the nose, and the comfortable surface can be obtained. Wear feeling. Moreover, it can also make the appearance look good.
