Abstract: A method of controlling a programmable lens device comprising a programmable lens and an optical function controller, the programmable lens having an optical function and extending between at least one eye of the wearer and the real world scene when the device is used by the wearer, and the optical function controller being arranged to control the optical function of the programmable lens, the method comprising: —an optical function data receiving step during which optical function data relating to the optical function of the programmable lens is received by the optical function controller, —an activity data receiving step during which activity data relating to the activity of the wearer are received by the optical function controller, —an optical function modifying step during which the optical function of the programmable electronic lens device is modified by the optical function controller based on the optical function data and the activity data.

Abstract: The invention provides a head-mounted display (1) comprising: —an optical module (2) containing an image source (21); —an imager (3) for guiding light emitted by the image source (21) to a wearer's eye (E) in operation; and —a light filter for filtering a portion of light emitted by the image source (21). The invention also provides an ophthalmic lens (4) intended to be mounted onto a head-mounted display (1) comprising an image source (21), wherein said ophthalmic lens (4) comprises a light filter intended to filter light emitted by the image source (21) of the head-mounted display (1) in operation.

Abstract: Method for encapsulating at least partly a light-guide optical element in a transparent capsule, the method comprising at least: —a transparent capsule providing step during which a transparent capsule is provided, —a light-guide optical element providing step during which a light-guide optical element is provided, —an adhesive deposing step during which an adhesive is deposited on at least part of a face of the transparent capsule and/or of a face of the light-guide optical element, —a positioning step during which the transparent capsule and the light-guide optical element are positioned one relative to the other so as to form an optical system, —a bonding step during which the light-guide optical element and the transparent capsule are made integral with the adhesive, wherein the method further comprises prior to the bonding step a control step during which at least one parameter of the optical system is controlled.

Abstract: A navigation method for a wearer of a see-through head mounted device, the method comprising: •—a wearer visualization parameter providing step (S1), during which at least one wearer visualization parameter is provided, •—a geo-position determining step (S2), during which the geo-position of the wearer along a route is determined, •—a geo-position comparing step during which the geo-position of the wearer determined during the geo-position determining step is compared to stored geo-positions along the route and •—a navigation visual aid function adapting step (S3) during which upon matching of the geo-position of the wearer with one of the stored geo-positions, the navigation visual aid function is adapted based on the wearer vision parameter and the geo-position of the wearer to facilitate the guiding of the wearer
