A method of manufacturing an ophthalmic lens (11) having at least one diffusing region (13) and at least one clear region (12) is provided. The method comprises the steps of: applying a material removal process to a lens blank to achieve an intermediate ophthalmic lens (11 ') having a final shape and a surface (11' b); and converting at least part of the surface (11'b) of the intermediate spectacle lens (11 ') into a transparent surface by means of a finishing process. The at least one diffusion zone (13) is formed by changing a finishing process for a first portion (13 ') of the surface that is to be the at least one diffusion zone (13) in comparison to a finishing process for a second portion (12') of the surface (11 'b) that is to be the at least one clear zone (12), such that the surface of the first portion (13') becomes a matte surface and the surface of the second portion (12 ') becomes a transparent surface. 提供了一种制造具有至少一个漫射区(13)和至少一个清晰区(12)的眼镜镜片(11)的方法。该方法包括以下步骤：将材料去除工艺应用到镜片毛坯，以实现具有最终形状和表面(11'b)的中间眼镜镜
