Abstract
Disclosed is a method of manufacturing an ophthalmic lens having at least one optical function, including the determination of a transmission spectrum in a wavelength range from 280 to 2000 nm, the determination of a matrix including at least two compounds absorbing light having a wavelength from 280 to 2000 nm, with regard to the determined transmission spectrum, and additively manufacturing the matrix.
