    • Highly compact molded eyeglasses include a first lens portion and a second lens portion coupled via a bridge member. Each lens portion may be characterized by a reference surface and an adjustment surface. From one pair of eyeglasses to another, the reference surface exhibits a constant curvature. The curvature of an adjustment surface is designed relative to that of a reference surface to provide a lens portion having a particular dioptic power. The transition section may include a corrugation and/or a lip to secure the glasses to a wearer's nose. The bridge member acts as a flat spring coupling the lens portions. The bridge member includes an indentation segment joined by bends or curves to a first and a second arm segment. The bridge member's structure provides positional memory properties. The bridge member and the lens portions may be made from polycarbonate in an injection molding process.
    • 高度紧凑的成型眼镜包括第一透镜部分和通过桥接部件连接的第二透镜部分。 每个透镜部分的特征在于参考表面和调节表面。 从一对眼镜到另一对眼镜,参考表面呈现恒定的曲率。 调整表面的曲率相对于参考表面的曲率设计,以提供具有特定屈光度的透镜部分。 过渡部分可以包括用于将眼镜固定到穿戴者的鼻子的波纹和/或唇缘。 桥构件用作联接透镜部分的平板弹簧。 桥构件包括通过弯曲或曲线连接到第一和第二臂段的压痕段。 桥梁构件的结构提供位置记忆属性。 桥构件和透镜部分可以由注射成型工艺中的聚碳酸酯制成。
