    • Describes a multifocal optical article, e.g., an ophthalmic article such as a lens, in which the article includes (1) a rigid optical substrate, e.g., a transparent polymeric substrate, such as a thermoset or thermoplastic substrate, adapted to possess at least one light influencing property on at least a portion of at least one surface of the substrate, e.g., a photochromic and/or polarizing layer, and (2) a multifocal layer of an optical quality material on said substrate having the light influencing property. Describes also the aforedescribed optical article having an abrasion-resistant coating on the multifocal layer, e.g., an abrasion-resistant coating comprising an organo silane. A method for preparing the multifocal optical article comprising curing optical quality material between a multifocal mold and a preform comprising an optical substrate possessing the light influencing property is also described.
    • 描述多焦点光学制品,例如眼镜制品如透镜,其中制品包括(1)刚性光学基底,例如透明聚合物基底,例如热固性或热塑性基底,适于具有至少一个 在基板的至少一个表面的至少一部分的光影响特性,例如光致变色和/或偏振层,以及(2)具有光影响性能的所述基板上的光学质量材料的多焦点层。 还描述了在多焦点层上具有耐磨涂层的上述光学制品,例如包含有机硅烷的耐磨涂层。 还描述了一种制备多焦点光学制品的方法,其包括在多焦点模具和包含具有光影响特性的光学基底的预成型件之间固化光学质量材料。
