Abstract: The disclosure relates to an analysis module having a communication component arranged to receive scene images from a scene camera mounted on a head mounted device, the scene images corresponding to images of the environment facing the user of the head mounted device when worn by the user, an image analysis component arranged to identify at least one predefined element from a list of predefined elements in a predefined analyzing zone of the images received from the scene camera and to analyze at least part of the scene images based on the identified at least one predefined element, and a feedback component arranged to generate feedback data and to send such data to the user of the head mounted device.

Abstract: A head mounted display device comprising: a light emitting source, an optical waveguide adapted to collect light emitted from the light emitting source and to guide the collected light to the eye of a wearer when the head mounted display device is being worn by the wearer, a controller device adapted to control the emitted spectrum and/or radiance and/or light level emitted by the light emitting source.

Abstract: The invention relates to the field of management systems and methods of an active device and more particularly, with said active device being an active ophthalmic lens, to a management system and method which allow a total or sufficient protection by taking into account the luminous environment of the wearer while avoiding some effects relative to permanent light filtering. According to a particular embodiment of the invention, there is also provided a monitoring of the wearer's health via active, regulated and continuous control of the active device, this control being performed for instance by a health professional via a remote monitoring system.

Abstract: 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.

Abstract: A monitoring system for monitoring the visual behavior of a wearer of a head-mounted device, the monitoring system includes: —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, —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, —a wearer information data generating unit configured to: —receive the wearer's visual behavior data, —store the wearer's visual behavior data, and—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.

Abstract: 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.
