The invention relates to filter dedicated to protect eye cone cells and method associated. The eye cone cells protecting filter is intended to be applied to a transparent surface and to filter incident light for preventing eye cone cells of a user, from damages due to illumination at physiological light levels on the eye of said user, and having spectral characteristics to i) filter light wavelengths between 405 and 465 nanometers, and ii) transmit a filtered light reaching the eye cone cells and having a harmfulness on said eye cone cells under a predefined maximum threshold.

Filter for eye cone cells protection

An optical system having a spectral transmission profile having an average transmittance Ta between 380 nm and 780 nm and an average red light transmittance Tr between a first limit L1 and a second limit L2, with Tr&#x3c;2*Ta/3 and L1=600 nm and L2=780 nm, and the optical system being configured to allow selectively retinal exposure of an eye to at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 530 nm.

Optical system for treating chronobiological disorders and/or myopia

Active optical filter adapted for a spectacle lens, the active optical filter being configured so as to filter light radiations over at least one predetermined range of wavelengths, wherein the full width at half maximum of the filtering function of the optical filter is smaller than or equal to 100 nm.

Active optical filter for spectacle lenses

An optical device including an optical substrate providing with an optical filter configured to inhibit transmission of harmful UV and/or blue light wherein the optical device is further configured to allow retinal exposure of an eye to at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 560 nm, preferably of 480 nm to 520 nm.

Optical device

An active optical filter adapted for a spectacle lens, the active optical filter configured to filter light radiations over at least one predetermined range of wavelengths, wherein the full width at half maximum of the filtering function of the optical filter is smaller than or equal to 100 nm.

The disclosed embodiments include user fatigue level analysis components, real-time visual behavior measuring devices, and methods for determining the fatigue level of a user. In one embodiment, a user fatigue level analysis component includes a memory configured to store computer executable instructions and a processor for executing the computer executable instructions. The computer executable instructions comprise instructions for receiving at least a visual behavior parameter indicative of the real time visual behavior of the user, for providing at least one sleep quality history parameter indicative of the sleep quality history of the user, and for determining the fatigue level of the user based on the analysis of the combination of the at least one visual behavior parameter and the at least one sleep quality history parameter.

User fatigue level analysis component

A monitoring system for monitoring the visual behavior of a wearer of a head-mounted device, the monitoring system includes: &#x2014;a least one wearer's visual behavior sensor configured to sense at least one wearer's visual behavior data relating to the visual behavior of the wearer of the head-mounted device, &#x2014;a communication unit associated with the at least one wearer's visual behavior sensor and configured to communicate the visual behavior data to a wearer information data generating unit, &#x2014;a wearer information data generating unit configured to: &#x2014;receive the wearer's visual behavior data, &#x2014;store the wearer's visual behavior data, and &#x2014;generate an wearer information data indicative of at least one of: wearer's vision or general health condition of the wearer or wearer's activity or wearer's authentication based, at least, on the evolution over time of the wearer's visual behavior data.

Monitoring system for monitoring head mounted device wearer
