摘要： A system and method for designing a progressive lens. Mean power is specified at points distributed over the entire surface of the lens and lens height is specified around the edge of the lens. Lens height is determined at the points consistent with the specified mean power and the lens edge height in part by solving a partial differential equation of the elliptic type subject to the lens edge height as a boundary condition. A successive over-relaxation technique may be employed to converge on the solution to the partial differential equation, and an over-relaxation factor may be determined to most efficiently relax the equation.

摘要： The invention generally relates to a lens and the method of manufacturing progressive addition lenses (PAL) to remove unwanted base out prism and minimize excessive convergence, comprising determining basic configuration of two major lens surfaces to provide a distance portion and near portion, wherein diopter power increases from the distance portion of the lens to the near portion; selecting an amount of prism reduction; and reducing base out prism that inherently occurs as diopter power increases by altering the configuration of the lens as a function of the amount of prism reduction to minimize any disruption of optical properties a lens while decreasing base out prism.
摘要翻译：本发明一般涉及一种透镜和制造渐进式附加透镜（PAL）以去除不需要的底出棱镜并最小化过度收敛的方法，包括确定两个主透镜表面的基本配置以提供距离部分和近部分，其中屈光度从透镜的距离部分增加到近部分; 选择棱镜数量减少; 并且通过改变透镜的配置作为棱镜减少量的函数来增加屈光度功率而增加固有地出现的底出棱镜，以最小化透镜同时减少底出棱镜的光学特性的任何破坏。
