摘要：
A method of designing a lens precursor form (105B) comprising defining a lens precursor form design, the design including a lens edge (HOB) that defines the outer perimeter of the lens precursor form; a plurality of lens features selected from the group consisting of a lens edge feature that is present along at least part of the lens edge, an optic zone (125B) that is present within the outer perimeter of the lens precursor form, a stabilization zone feature (115B) that is present within the outer perimeter of the lens precursor form, and a volumator feature (120B) that is present within the outer perimeter of the lens precursor form between at least two of the said plurality of lens features; wherein each of the lens features is parametrically defined and wherein the parameters defining at least one lens feature are selected based at least in part upon the parameters defining one or more adjacent lens features and a desired lens shape.
摘要（中）：
一种设计透镜前体形式（105B）的方法，包括限定透镜前体形式设计，该设计包括限定透镜前体形式的外周边的透镜边缘（HOB）; 多个透镜特征，其选自沿着透镜边缘的至少一部分存在的透镜边缘特征，存在于透镜前体形式的外周边内的光学区（125B），稳定区特征 （115B），其存在于所述透镜前体形式的外周边内，并且存在于所述透镜前体的外周边内的体积特征（120B）形成在所述多个透镜特征中的至少两个之间; 其中每个透镜特征被参数地限定，并且其中至少部分地基于限定一个或多个相邻透镜特征和期望透镜形状的参数来选择限定至少一个透镜特征的参数。
