Progressive multifocal spectacle lens and design method thereof

The invention discloses a progressive multi-focus spectacle lens and a design method thereof. The design method comprises the following steps: dividing the surface of the spectacle lens into a spherical surface and a disturbance surface by using a linearization method; the disturbance surface is optimized; overlapping the optimized disturbance surface and the spherical surface to obtain the optimized surface of the spectacle lens, and performing Zernike polynomial fitting on the optimized surface of the spectacle lens to obtain lens data; and smoothing the lens data, and processing according to the smoothed lens data to obtain the progressive multi-focus spectacle lens. The method is suitable for design of most progressive multi-focus spectacle lenses, the design process is more flexible and efficient, the overall optical performance of the progressive multi-focus spectacle lenses can be effectively improved, and the whole optimization design process is more personalized. 本申请公开了一种渐进多焦点眼镜片及其设计方法，包括以下步骤：运用线性化方法
