Disclosed is a method for determining at least one fitting parameter of an optical equipment configured to equip a user, the method including: providing an imaging device; taking a plurality of images of the user equipped with the optical equipment when the user takes successively at least two distinct positions; among the at least two distinct positions, identifying at least one period when the user is in a favorable position to determine the at least one fitting parameter, wherein the at least one period is manually identified by an operator; recording the at least one identified period and at least one image taken during the at least one identified period; determining the fitting parameter on the basis of the at least one recorded image.

A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.

The disclosed transparent circuit board may include a transparent substrate, a first conductive trace coupled to the transparent substrate, and an electrical component having a bottom surface facing the transparent substrate and a top surface facing away from the transparent substrate. The bottom surface may include a first electrical contact coupled to the first conductive trace, and the top surface may include a second electrical contact. The transparent circuit board may also include a second conductive trace electrically connected to the second electrical contact and a transparent encapsulation layer coupled to the transparent substrate and encapsulating the electrical component. Various other ophthalmic devices, systems, and methods are also disclosed.

An accessory for eyeglasses that functions as a combined hearing aid and/or eyeglasses retention device which can maintain housings of behind the ear (BTE) hearing aids in place on a user's ears. The combined hearing aid and/or eyeglasses retention device can also maintain eyeglasses from slipping down the nose of a user which also maintains the device at its optimal position to retain housings of BTE hearing aids in place. The combined hearing aid and/or eyeglasses retention device also prevents displacement of BTE housing(s) off a user's ears when a user removes a mask. The combined hearing aid and/or eyeglasses retention device can also be a ‘standalone’ eyeglasses retention device when a user does not wear BTE hearing aids.

A lanyard for securing a mixed reality device or a smart frame to a body of a user, is provided. The lanyard includes a first connector and a second connector, at least one of the first connector or the second connector configured to couple to a first leg and a second leg in the mixed reality device by at least one of a mechanical, a magnetic, or a chemical fitting. The lanyard also includes a cord separating the first connector from the second connector, and a power circuit configured to transfer a power between the mixed reality device and the lanyard through the first connector or the second connector. The cord includes an energy transfer component providing one of a digital signal to a processor in the mixed reality device, or the power from the power circuit to the processor of the mixed reality device.

Systems, devices, media, and methods are described for capturing a series of raw images by portable electronic devices, such as wearable devices including eyewear, and automating the process of processing such raw images by a client mobile device, such as a smart phone, such automation including the process of uploading to a network and directing to a target audience. In some implementations, a user selects profile settings on the client device before capturing images on the companion device, so that when the companion device has captured the images, the system follows the profile settings upon automatically processing the images captured by the companion device.

An eyewear retention apparatus is configured for use with an eyeglass frame having a pair of temples, each temple having a first extremity configured to attach to a lens holder and a second extremity configured to rest behind an ear of a wearer. The eyewear retention apparatus includes a strap formed of a flexible material and having a length extending between first and second ends, wherein each of the first and second ends includes a first hole extending through the strap. The eyewear retention apparatus also includes first and second fittings, each of the first and second fittings includes an end region having an opening configured to receive a respective one of the second extremity of the pair of temples and a tab having a second hole. The eyewear retention apparatus further includes a fastener extending through the first hole and the second hole.

A frame for a head mounted device including: a front part; a first temple configured to be electronically connected to the front part via a first connection and including a battery providing electrical power arranged in a cavity in the first temple and connected electrically to the first connection; a second temple configured to be electrically connected to the front part and having a cavity therein configured to receive therein at least one electronic module; and a second connection configured to connect electrically the battery of the first temple to the at least one electronic module of the second temple via the front part to receive power therefrom.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Embodiments of the disclosure include an integrated eyewear and headgear system, including retrofitting existing headgear and eyewear, allowing the eyewear to remain attached, affixed to, or connected with headgear while not in use (not covering the eyes), as well as when in use (covering the eyes). A headgear and eyewear system may comprise eyewear configured to be worn on the face of a user; headgear configured to be worn on the head of the user; and at least one retaining mechanism configured to attach the eyewear to the headgear, wherein the eyewear comprises a first position in front of the user's eyes, wherein the eyewear comprises a second position upon the headgear and not in front of the user's eyes, and wherein the retaining mechanism is configured to retain the eyewear with respect to the headgear in at least one of the first position and the second position.
