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.

Abstract: The invention provides a method for evaluating at least one light protection level of at least one optical product intended to face an eye of a user, the method comprising the following steps: —determining at least one short-term light protection score representative of at least one short-term light protection attribute, —determining at least one long-term light protection score representative of at least one long-term light protection attribute, evaluating at least one light protection level of at least one optical product based on said at least one short-term and at least one long-term protection scores. The invention also provides an optical product comprising a frame, at least one optical system product attached to said frame and intended to face an eye of a user, a data collecting device and a controller configured to perform said evaluating method.

Abstract: This ophthalmic lens for improving vision has a light cut factor CutLED between 32% and 90%, for wavelengths ranging from 380 nm to 500 nm, defined by formula (I), where Σ is a discrete or continuous sum operator, λ is the wavelength in nm, lens T % is the spectral transmittance of the lens in % and LED emission is the spectral distribution of a white light emitting diode; a mean luminous transmittance in the visible range higher than or equal to 75%; and light transmitted through the ophthalmic lens has a colorimetric value b*, as defined in the colorimetric CIE L*a*b* with illuminant D65, lower than 25.
