摘要

渐进多焦点镜片的面形设计是在镜片表面初始矢高模型基础之上进行的，设计的关键在于镜片子午线曲线的选择。通过对渐进多焦点镜片的渐变区面形分析，对镜片变化的曲率中心的方位准确定向，分析了曲率渐变对镜片像散和棱镜度的影响，提出了一种采用渐开线作为渐进多焦点镜片子午线曲线的设计思路，并建立了基于渐开线作为渐变区子午线的渐进多焦点镜片表面初始矢高模型。

Abstract

The face shape design of progressive addition lenses is based on the original vector height model of the lens surface. The key of the design lies on the choice of the meridian curve of the lens. Based on the analysis of surface shape in gradient zone of progressive addition lenses, accurate orientation of the center of curvature of the lens is made. The influence of the gradient curvature on the lens astigmatism and prism degree is analyzed. A design idea of using involute as the meridian of progressive addition lens is presented. The initial vector height model of the surface of the progressive addition lens is established based on the involute as the meridian in gradient area.
