An elastic rim lock without screws for eyeglasses operating as hinge and temple is described, comprising: a spring, a first front frame part, a second front frame part and a cut, the spring being tensioned between a head of the wire and a surface of a first seat of the second front frame part separated by the cut, the rim lock further comprising a wire, a first segment of the wire passing through the spring, the first seat, a second seat of the second front frame part and a seat of the first front frame part, while a second segment of the wire is in permanent contact with a surface of the first front frame part and has the function of defining the length of the first segment, a section of the wire being configured for being a temple or a temple core.

An assembly structure for eyeglass lens comprises a lens and a connection component. The lens is formed with an insertion section at one end which end toward to the connection component and at least one engaging hole in the insertion section. The connection component is formed with a slot at one end which end toward to the lens, and connected to a temple at the other end which end far away the lens. The slot is formed with a pin on the wall. After the insertion section of the lens is inserted into the slot of the connection component, the pin on the slot wall is engaged with the engaging hole of the insertion section, assembling the lens and the connection component together.

A modular eyewear system is disclosed that comprises a plurality of bridges and at least one of a plurality of left lens holders and a plurality of right lens holders. Any one of the bridges can be assembled with any one of the left lens holders and/or the right lens holders. Further embodiments of the modular eyewear system, methods of assembly, and uses thereof are disclosed herein.

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.

Eyeglass frames include a face member and two temple members connected to the face member. The face member includes a rim with a brow configured to retain at least one lens. A nose member is connected to the face member and supports the rim separated from a face of a wearer by a gap. A vent passage is provided in the brow and extends from a front portion of the brow to a rear portion of the brow. A vent adjustment member provided on the brow directly above the at least one lens. The vent adjustment member is configured to move between a first position wherein the vent passage is substantially closed and a second position wherein the vent passage is open. The vent adjustment member is substantially flush with a medial portion and a lateral portion of the brow when the vent adjustment member is in the first position and offset from the medial portion and lateral portions of the brow when the vent adjustment member is in the second position.

A hinge device for eyeglasses includes an accommodation body provided with engagement seats for gripping and locking a hinge body to an end piece of an eyeglass frame. The hinge body includes a central body that is adapted to engage within the accommodation body. The central body is further configured to engage in turn a temple of the eyeglass frame.

An article of eyewear may include a frameless, rigid lens configured to cover both eyes of a wearer when worn. The lens has a generally cylindrical curvature in a side-to-side direction, such that lateral ends of the lens are rearward of a central nose bridge. A pair of temples are attached to the lens, each temple including a mounting portion configured to releasably mate with the lens and a temple arm pivotably coupled to the mounting portion. In some examples, a vertical cross section taken at the nose bridge of the lens has an S-shaped profile, and a vertical cross section taken in an area between the nose bridge and a lateral end of the lens has a C-shaped profile.

The present invention relates to a snap-fit structure for spectacle lens and temple, which comprises a spectacle lens with a buckle hole on a side thereof, and a temple with a lens assembly element. A latching member is pivotally connected in a groove of the lens assembly element. When the spectacle lens and the temple are assembled, the side of the spectacle lens is correspondingly engaged with an embedded opening of the lens assembly element, so that the buckle hole of the spectacle lens is put between an elastic piece and a pressing piece of the latching member, and is coupled with a block of the elastic piece correspondingly. When the spectacle lens is separated from the temple, the pressing piece of the latching member is pressed to deflect the latching member by an angle, so that the elastic piece is separatable from the buckle hole of the spectacle lens.
