    • Disclosed herein is a spectacles and sunshade clip assembly using magnets. The magnets serve to detachably attach the sunshade clip to the spectacles. The spectacles comprises a pair of lens frames connected to each other by means of a nose bridge, and temple arms connected, respectively, to the lens frames by means of magnetically-induced hinges. The sunshade clip comprises a pair of sunshade lenses formed by cutting a colored plastic plate into a desired lens form, and a sunshade bridge formed by injection molding and adapted to connect the sunshade lenses to each other. Two magnet ribs are coupled to opposite outer ends of the sunshade lenses to extend in opposite directions. Each of the magnet ribs is configured to substantially coincide with the outer contour of the hinge provided at the spectacles and has a magnet mounted to face the hinge.
    • 本文公开了使用磁体的眼镜和遮阳夹组件。 磁铁用于将遮阳夹可拆卸地安装在眼镜上。 眼镜包括通过鼻梁彼此连接的一对透镜框,以及通过磁感应铰链分别连接到透镜框的镜腿臂。 遮阳夹包括通过将彩色塑料板切割成期望的镜片形式而形成的一对遮阳透镜,以及通过注射成型形成并适于将遮阳镜彼此连接的遮阳桥。 两个磁肋连接到遮阳透镜的相对的外端,以相反的方向延伸。 每个磁肋构造成与设置在眼镜处的铰链的外轮廓基本一致,并且具有安装成面向铰链的磁体。
