Abstract
The invention concerns method and system for determining a lens of customized color, said method comprising the steps of determining a target colorimetric data set; providing access to a database comprising data representing colors; using a plurality of simulation modules to calculate, based on said data from the database, a plurality of simulated colorimetric data of the lens substrate combined with a mixture of dyes of determined dye(s) combination, composition and amount or with a multilayer stack as a function of determined layers composition and thicknesses; and, color matching the plurality of simulated colorimetric data with the target colorimetric data set so as to determine one or a plurality of combinations of said lens substrate with a determined mixture of dyes or with a determined multilayer stack.
