Abstract
The invention relates to a method for manufacturing an ophthalmic lens having at least one optical function, comprising the step of providing a starting optical system of the lens, having a basic optical function and the step of additively manufacturing an additional optical element of the lens, by deposition of multiple predetermined bulking components made of at least one material having a predetermined refractive index, directly onto the front surface and/or the rear surface of the starting optical system; wherein the additive manufacturing step comprises the step of determining a manufacturing guideline for the additional optical element on the basis of the characteristics of said at least one optical function to be provided to the lens, the characteristics of said at least one basic optical function, the geometric characteristics of the starting optical system, and the predetermined refractive index of the material.
