摘要
本文研究高屈光度眼用透镜消除离轴像散的非球面化模式。借助数字例子的设计计算结果表明，眼用透镜的非球面化，不仅使“西林”椭圆曲线的图解技术得到了扩展，而且能利用非球面的偏心率有效控制高级像散，提高视觉成像质量。
In this paper, model of aspherisation for higher-dioptry spectacle lens is investigated.By design of numerical examples, it is demonstrated that aspherisation of spectacle lens not only extendes diagrm technic of Tscherning's elliptic curve but more controls higher-order astigmatism by using aspheric eccentricity, and increases imgae guatity for visual sense.
