A multiple degree of freedom hinge system is provided, which is particularly well adapted for eyewear, such as spatial computing headsets. In the context of such spatial computing headsets having an optics assembly supported by opposing temple arms, the hinge system provides protection against over-extension of the temple arms or extreme deflections that may otherwise arise from undesirable torsional loading of the temple arms. The hinge systems also allow the temple arms to splay outwardly to enable proper fit and enhanced user comfort.

An eyeglass with angle of lens adjustable depending on multi focus lens includes a frame and two lenses. The frame is provided with a rim and two temples. The rim is provided with two rotating portions located at two opposite outer sides of the rim. Each temple is provided with a mounting portion pivotally connected to one of the rotating portions. The lenses are mounted to the rim symmetrically. In this connection, each lens is provided with a regular-prescription area having vision zones. The vision zones include a short-range vision zone, a middle-range vision zone and a long-range vision zone. When the present invention is used, the rotational cooperation of the short-range vision zone, middle-range vision zone and long-range vision zone with the temples is utilized, so as to solve the problem of incapability of aligning lenses in the conventional practice with eyes suffering from presbyopia.

Spectacles (1) comprise a front frame (2) and a pair of arms (10), wherein each arm extends between a first end (11) attached to the front frame and a second, longitudinally opposed end (12). Each arm comprises a first portion (20) associated with the first end and extending along a first axis (X), and a second portion (30), associated with the second end and extending along a second axis (Y), these portions abutting one another at a first bearing plane (A) which is not perpendicular to the first and second axes, and being selectively rotatable about (20) an adjustment axis (K) perpendicular to the first bearing plane (A) to vary the inclination between the first and the second axis. The first portion comprises a first element (21) and a second element (22), abutting one another at a second bearing plane (B) perpendicular to the first axis, the elements being selectively rotatable about the first axis. The second portion (30) comprises a third element (31) and a fourth element (32), abutting one another at a third bearing plane (C) perpendicular to the second axis (Y) and selectively rotatable about the second axis.

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.

A protective eyewear with dual-mode sidearms allows the eyewear to be worn in the presence or absence of earmuff-type hearing-protection apparatus. The protective eyewear comprises: an eyeshield; a first sidearm that is pivotally connected to the eyeshield by a first primary pivotal connection that is located proximate a first major end of the eyeshield; and a second sidearm that is pivotally connected to the eyeshield by a second primary pivotal connection that is located proximate a second, opposing major end of the eyeshield, wherein at least a rearward portion of a second, rear part of each sidearm comprises a laterally-outward-and-downward-facing major surface that is a concave surface, wherein the primary pivotal connection of each sidearm is configured so that each sidearm can be pivotally moved between at least a first, lowered configuration and a second, raised configuration, and wherein the sidearms are configured so that when the protective eyewear is worn in combination with an earmuff-type hearing-protection apparatus and when both sidearms are in the second, raised configuration, the rearward portion of the rear part of each sidearm rests atop a junction between an uppermost portion of a compliant seal of an earmuff of the hearing-protection apparatus, and a side of a user's head.

An apparatus includes a frame, a left temple, a right temple, a left end piece, a right end piece, a left hinge, and a right hinge. The frame includes a left side and a right side and the frame may support a plurality of lens. The frame of the apparatus that improves vision may be tilted to provide the lenses at varying angles and lock into place via a latching mechanism. The effect of the tilted lens provides significantly increased clarity and definition of vision, with no expensive custom lenses or magnification.

A slip-resistant eyewear system comprising an eyewear frame generally comprises a nosepiece comprising a nosepiece material configured to couple to a bridge of an eyewear frame. The frame comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second spring-loaded tension adjusters. First and second bows are coupled to first and second tension adjusters. A unitary eyewear retainer comprises 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.

A multiple degree of freedom hinge system is provided, which is particularly well adapted for eyewear, such as spatial computing headsets. In the context of such spatial computing headsets having an optics assembly supported by opposing temple arms, the hinge system provides protection against over-extension of the temple arms or extreme deflections that may otherwise arise from undesirable torsional loading of the temple arms. The hinge systems also allow the temple arms to splay outwardly to enable proper fit and enhanced user comfort.

The present application provides a pair of spectacles, an assembly of a spectacles temple and an endpiece, and a spectacles hinge. The guide member (30) is provided with a first guide groove (31) and a second guide groove (32) that are vertically intersected, the first connecting portion (11) and the second connecting portion (21) are respectively extended into the first guide groove (31) and the second guide groove (32) and hinged in the guide member (30), so as to realize that the spectacles hinge (100) can rotate in two mutually perpendicular directions; the bottom surface of the first guide groove (31) on the guide member (30) is provided with a first inclined surface (351), such that the first connecting member (10) can be rotated between the open position and the closed position without jamming.

A pair of eyeglasses includes a glasses frame, two connecting members, and two temples. The glasses frame includes a first end and a second end spaced from the first end in a lateral direction, each of which forms a coupling base extending inward in a longitudinal direction perpendicular to the lateral direction. Each connecting member includes spaced first and second segments, and the first segment is detachably connected to a corresponding coupling base of the glasses frame. Each temple performs upward/downward pivotal rotation relative to the glasses frame according to an axis defined by a pivot which connects the front end of each temple with the second segment of one of the connecting members. The pair of eyeglasses allows each temple to be removed from the glasses frame easily.
