    • An improved method for creating a multi-layered optical lens structure which appears, from an observer's point of view, to have a brushed metal finish, matte finish, decorative pattern, image or logo on the surface of a sunglass lens, but which is optically transparent from a wearer's point of view. The present method for creating a lens structure does not require the use of epoxies or adhesives and allows the lens structure to be made as a polarized lens. The present method offers vast improvements over previously disclosed methods in that it simplifies assembly of the lens structure, allows for greater repeatability, and significantly improves the optical clarity of the final lens structure.
    • 一种用于创建多层光学透镜结构的改进方法,从观察者的角度来看,在太阳镜透镜的表面上具有拉丝金属表面,无光饰面,装饰图案,图像或徽标,但是光学上 透明度从佩戴者的角度来看。 用于产生透镜结构的本方法不需要使用环氧树脂或粘合剂,并且允许将透镜结构制成偏光镜片。 本方法相对于先前公开的方法提供了巨大的改进,因为它简化了透镜结构的组装,允许更大的重复性,并且显着地改善了最终透镜结构的光学透明度。
