An electronic device according to an aspect of the present invention comprises a case formed of an ultra-light fabric material; a frame coupled to the case and supporting the case; and a face pad coupled to the frame, wherein ultra-light fabric material comprises an ultra-light material comprising a thermoplastic resin and a core material dispersed in thermoplastic resin; and a fabric thermo-compressed on at least one side of the ultra-light material by thermoplastic resin.

The disclosed computer-implemented method may a strap adjustment mechanism having a first strap and a second strap positioned to at least partially overlap the first strap. The strap adjustment mechanism may also include a first strap adjuster, and a proximal portion of the first strap may be coupled to the first strap adjuster and the second strap is threaded through the first strap adjuster. In addition, the strap adjustment mechanism may include a second strap adjuster, and a proximal portion of the second strap is coupled to the second strap adjuster and the first strap is threaded through the second strap adjuster. Various other devices, systems, and methods are also disclosed.

This invention relates to a device used to attach to eyewear for the purpose of providing buoyancy, securing to the head and temples, and protection from scratches.

A headband for VR goggles includes an adjustment mechanism to accommodate a wide variety of users, padding to ensure user comfort, a pivotable goggle holding element to allow the goggles to pivot relative to the user's head and a chin strap fastener to secure the headband to the user's head.

An eyewear retention device that comprises two retaining devices, each meant to be positioned on a temple member of a pair of eyeglasses. The retainer devices are meant to be positioned between the concha and pinna of the ear so that hold the eyeglasses on the nose of the wearer securely at the wearer's desired portion without any slippage of the eyeglasses along the nose.

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.

An adjustable goggle strap includes a strap body and an adjustment cord disposed on the strap body. The adjustment cord may be releasably engaged by a cord lock in order to modify a total length of the strap body. The cord lock may be located on the strap body or various elements of an attached eyewear, such as an eyewear frame, lens, or eyewear strap attachments. Some aspects of the adjustable goggle strap include a retainer to secure an excess portion of the adjustment cord.

A skin contact pad for eyeglass frames that helps increase the friction between the skin and the eyeglasses. The skin contact pad has a body with a face surface that touches the skin of a person wearing the eyeglasses. Concavities are formed on the skin contact pad. Each of the concavities has a concave surface defined within an encompassing base. The encompassing base of each concavity is independent and complete. As the concavities move across skin, the skin bulges slightly into the concavities. As the skin moves under the concavities, the bulges move and a slight suction is created within the concavities that bias the skin contact pad toward the skin. The bias that is created helps hold the eyeglasses in place on the head of a user.

Implementations of a counterweight device for eyeglasses are provided. In some implementations, a counterweight device may be secured to the backend of each temple and thereby remove some to all weight of the eyeglasses from the nose and/or cheeks of the wearer. In some implementations, a pair of counterweight devices may be used to counterbalance the weight of a pair of eyeglasses. In some implementations, a counterweight device may comprise an elastic loop attached to a weight by a connector. In some implementations, a counterweight device may include fasteners configured to removably secure a weight to an elastic loop or to another weight dangling from an elastic loop. In this way, through the use of threaded fasteners, the overall weight and/or look of a counterweight device may be changed by the wearer. In some implementations, a lanyard may be used in conjunction with a pair of counterweight devices.
