An eyeglass structure includes a bridge, a first frame portion, and a second frame portion. The bridge includes a first lateral bridge column and a second lateral bridge. The first frame portion includes a first leaf spring having a distal portion configured to reach around and rotate about the first lateral bridge column. A first tab configured to engage the bridge to limit rotation of the first frame portion is further included in the first frame portion. Likewise, the second frame portion includes a second leaf spring having a distal portion configured to reach around and rotate about the second lateral bridge column, and a second tab configured to engage the bridge to limit rotation of the second frame portion.

Described is a wearable item, such as eyewear, that is formed to be stored and worn on a user's wrist. The eyewear includes a pair of lenses separated by a nose bridge assembly. Arms are affixed with each of the lenses. Notably, the pair of lenses are foldable between an open configuration in which they can be worn as eyeglasses and a collapsed configuration in which they fold toward one another and can be worn on the user's wrist.

Eyeglasses are provided for folding into a substantially flat configuration to be fitted inside a compact case. The eyeglasses include a frame surrounding a pair of lenses, and a pair of temples which extend from respective outer edges of the frame. A first hinge connection positioned on each temple allows outer parts of the pair of temples to be folded horizontally inwards from the unfolded configuration into a first folded configuration. Respective inner parts of the temples are rotatable downwards relative to opposite side edges of the frame about respective second hinge connections into a fully folded condition substantially coplanar with the frame. In some embodiments, the frame and tips or earpieces of the temples are of rigid plastic material while the temples and hinge connections are of metal.

An eyeglass apparatus comprises left and right eyeglass portions and a link. The link is configured to permit the eyeglass apparatus to transition between an extended configuration and a collapsed configuration. In the extended configuration, the eyeglass apparatus is adapted to be worn by a user in a conventional eyeglass wearing orientation. In the collapsed configuration: an inwardly facing lens face of one of left and right lenses faces an outwardly facing lens face of the other of the left and right lenses; a medial edge portion of the left lens is closer to a medial edge portion of the right lens than to a lateral edge portion of the right lens; and the lateral edge portion of the left lens is closer to the lateral edge portion of the right lens than to the medial edge portion of the right lens.

A retaining device for reading glasses comprises a lanyard and counterweights slidable engaging the lanyard. The counterweights are movable by sliding such that the counterweights hang in behind a user's ears to retain glasses on the user, when foldable temple pieces do not include ear pieces, such that the temple pieces do no rest on a user's ears. Instead, the lanyard extends over the user's ears and the counterweights apply a force, due to gravity, that acts opposite to the force of gravity on the glasses, retaining the glasses on the user's nose. For example, the glasses may be foldable into a pendant and may be retained on the user's neck until needed.

A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.

Eyeglasses (10), in particular of the folding type, composed of a front part (11) including respective lens elements (12, 12) and elements (14, 14) for hooking to the wearer's face, the front part (11) including first and second lens elements (12, 12) which are connected to each other by corresponding bridge members (16) including a respective bridge body (18) and elements (20, 20) for fastening the bridge body to the respective first and second lens element (12, 12). The elements for fastening the body to the respective first and second lens elements (12, 12) include, or are in the form of, corresponding wire-like members, in particular metal wire (20, 20), which are adapted to define respective elements for articulating and rotating the bridge body (18) relative to the lens elements (12, 12).
