Method for efficiently optimizing progressive addition ophthalmic lens based on Zernike polynomial

The invention provides a method for efficiently optimizing a progressive addition ophthalmic lens based on a Zernike polynomial. Firstly, a Zernike polynomial is used for fitting a preliminarily designed progressive multi-focus ophthalmic lens to obtain Zernike coefficients, all the coefficients are set as optimization variables, a conventional optimization algorithm is used for optimization, and a preliminary optimization direction is obtained. Under the condition that the optimization direction is basically unchanged, dimension reduction is carried out on optimization variables, the optimization time is shortened, and the optimization efficiency is improved. According to the method, the optimization efficiency of optimizing the progressive addition ophthalmic lens by adopting the Zernike coefficient can be greatly improved. 本发明提出一种基于泽尼克多项式高效优化渐进多焦点眼用镜片的方法。首先采用泽尼克多项式对初步设计的渐进多焦点眼用镜片进行拟合得到泽尼克系数，将所有系数设为优化变量，采用常规优化算法进行优化，得到初步优化方向。然后在保证优化方向基本不变的情况下，将优化变量降维，缩短优化时间，提高优化效率。本发明可以大幅度提高采用泽尼克系数优化渐进多焦点眼用镜片的优化效率。
