Abstract: An optical device including an optical substrate including a first surface having a first zone provided with first selective interferential filtering element for selectively inhibiting transmission of incident light based on the wavelength spectrum of the incident light, the first selective interferential filtering being configured to inhibit, at a first rate of rejection, transmission of a first selected range of wavelengths of incident light, incident on the first zone within a first selected range of angles of incidence, wherein the first selected range of angles of incidence is determined based on at least one main line of sight of a user.

Abstract: Method of determining configuration of interferential filtering elements for an optical device having an optical substrate for a user, includes: providing a first set of parameters representative of at least one main line of sight of the user; determining a first selected range of angles of incidence based on the first parameters; providing a second set of parameters characterizing, for the user, a range of wavelengths to be at least partially inhibited; determining a first selected range of wavelengths of incident light to be at least partially inhibited, based on the second parameters; and configuring a first selective interferential filtering element and a first zone of a surface of the optical substrate based on the first selected range of angles of incidence and wavelengths such that the first selective interferential filtering elements inhibit, at a first rate of rejection, transmission of the first selected range of wavelengths of incident light.

Abstract: An optical device including: an optical substrate provided with selective optical filtering element configured to selectively inhibit transmission, through the optical substrate of at least one selected range of wavelengths of incident light in the visible light spectrum at an inhibition rate of at least 5%, the selective optical filtering element being further configured to transmit at least 8% of incident light of the visible spectrum outside the at least one selected range of wavelengths; wherein the at least one selected range of wavelengths has a bandwidth in a range of from 10 nm to 70 nm, preferably 10 nm to 60 nm centered on a wavelength within a range of between 430 nm and 465 nm.
