An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.

The embodiments disclose a modular eyeglasses apparatus including a first and second temple interchangeably lockable to a first and second eyeglasses frame end, a first and second temple lockable receiver coupled to the first and second eyeglasses frame end, a lockable lever device coupled to the receiver having a lever handle having an upward angled section at one end and having an oblong section at the opposite end, an insertable section at one end of the first and second temple having a semi-circular depression configured to accept an elongated portion of the oblong section, rotating the lever handle downward toward the temple places the elongated portion into the depression to create a friction based coupling to lock the temple in an inserted position, and rotating the lever handle upward away from the temple retracts the elongated portion out of the depression to unlock the temple for removal from the receiver.

Eyewear of the present disclosure may include a frame having left and right rims, and a central bridge portion coupling the left rim to the right rim. A lens retainer has a first end pivotably coupled to an upper member of the central bridge portion and a second end releasably latched to a lower member of the central bridge portion. A lens is disposed on a front side of the eyewear frame and clamped to the frame by the lens retainer.

Interchangeable single-lens glasses include a mount with a front lens-holding frame having a bar extended at supraciliary arches between opposed lateral ends of the frame, and means for removable retention on the bar a single-lens structure extending frontally between the ends. The means for retaining the lens structure on the bar include, at each of the lateral ends, at least a respective first magnet or ferromagnetic material element provided on the frame and a second magnet or ferromagnetic material element provided on the lens in a corresponding position, to cooperate in reciprocal magnetic attraction with the corresponding first element, and, at a central portion of the bar, proximate to a nasal rest area of the mount, a relief protruding frontally from the bar and an opening passing through the lens in a corresponding position, the relief being configured to engage the opening with relative reciprocal locking.

An eyeglass lens replacement assembly is revealed. A frame includes a lens insertion slot disposed on a lower edge and a mounting indentation communicating with the lens insertion slot. A bevel is formed on each of two sides of the front end of the mounting indentation. A movable mounting member is mounted in the mounting indentation and has two mounting pins and a concave part formed on a middle part of the mounting pin. The upper edge of a lens is inserted into the lens insertion slot while the lens includes a mounting slot corresponding to the mounting pins and two protruding portions corresponding to the concave parts of the mounting pins. The movable mounting member can turn back and remain positioned by the bevels of the mounting indentation combined with recovery elasticity of the two mounting pins of the movable mounting member. No additional elastic members are required.

An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.

Eyeglasses include rims, at least one temple member connected to the rims, and at least one lens with a perimeter edge. The perimeter edge of the lens includes an upper perimeter edge, a lateral perimeter edge, a lower perimeter edge, and a medial perimeter edge. The rims are configured to retain the at least one lens with the upper perimeter edge of the lens engaging the rims. A vent arrangement is provided between the lens and the rims. The vent arrangement includes an opening between a lateral side of the rims and the lateral perimeter edge of the lens.

User configurable eyeglasses employing retention of lenses in eyeglass frames using elastic cushion connectors may include a pair of lenses, each lens comprising at least one tab extending from the lens. An eyeglasses frame may define at least two fittings, each fitting positioned to receive one tab extending from a lens and each fitting sized larger than the tab to be received. A plurality of eyeglass lens retention cushions are each adapted to be disposed in one of the fittings and to receive one of the tabs. Each eyeglass lens retention cushion might have an elastic cushion body having a relaxed, or in situ, exterior size larger than an interior socket of the fittings and may have an interior opening with a relaxed, or in situ, size smaller than a tab extending from an eyeglasses lens.

A pair of glasses includes an upper spectacle frame, a lower spectacle frame, two temples, and two snap-fit components. The lower spectacle frame has two lateral ends detachably integrated with two lateral ends of the upper spectacle frame. At least one lens is installed between the upper and lower spectacle frames. Each temple is pivotally fitted to one of the lateral ends of the upper spectacle frame. Each snap-fit component includes a first end at which a snap-fit portion is designed and a second end coupled with a corresponding temple. The snap-fit portion of each snap-fit component, which is in a fixed position, is inserted into a fastening hole in the at least one lens to fix the lens. The snap-fit portion of each snap-fit component, which is in a separate position, is separated from the fastening hole for replacement of the lens.

A lens exchanging structure of spectacles is disclosed. The lens exchanging structure of spectacles includes a trench disposed on a lens rim for receiving a lens. An open slot is disposed in the trench and has a long through hole having a first holey section and a second holey section. A moving part is placed in the open slot and has a bump disposed in the first holey section. A positioning part is disposed in the second holey section and assembled with the moving part. Therefore, the lens can be positioned or removed by the moving mechanism of the moving part in the open slot.
