| 摘要 | A lens for spectacles having at least one side thereof coated with a surface layer in a predetermined pattern so that transparent portions will be left on the lens. The transparent portions should have such an area that the light transmission rate will be larger than a predetermined value. The surface layer may be made of a fluorescent material, a light absorbing material or a light reflecting material. An interface layer such as a light absorbing layer may be interposed between the lens body and the surface layer. A protective layer may be provided on the surface layer. The lens may be made by bonding two half lenses with surface layers sandwiched therebetween. | ||||||
