Abstract: The invention relates to a method for manufacturing an ophthalmic lens having at least one optical function, comprising the step (200) of providing a starting optical system of the lens, having a basic optical function and the step (500) 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.

Abstract: Method for determining optical equipment comprising at least one optical lens and a spectacle frame. Wearer data relating to the wearer's optical requirements, wearer's face morphology and optical equipment position on the wearer face are provided. An optical cost function is provided related to an optical function of the at least one optical lens when worn by said wearer. A light protection cost function is provided related to a spectral irradiance estimation over the wearer eye and/or wearer skin in a peri-orbital zone of the wearer eye under a given condition when said optical equipment is worn by said wearer. The optical equipment that minimizes the difference between a global cost function and a target value of the global cost function is determined, the global cost function being a function of the optical and the light protection cost functions.
