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.

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.

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 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.

The present disclosure relates to a novel eyewear system and a method to configure the same. An eyewear system consistent with the present disclosure comprises an eyewear frame and a lens casing attached thereto. The eyewear system comprises a set of insertable lenses fitted between said eyewear frame and said lens casing. The lens casing comprises a pliable material to receive the set of insertable lenses. Further, the present disclosure provides a method for a consumer to design and order a pair of eyewear using an online system. The method may include prompting a user to choose from a plurality of unique frame options. Based on the user's selection of the frame, display to the user a plurality of lens casing options. In addition, based on the user's selection of the lens casing options, associate the selected frame and the selected lens casing with a customer order.

The present invention provides a screwless eyeglass frame, comprising a rim support, a temple support and a a pivoting clip. The rim support comprises a first end face and an engagement slot recessed inwardly from the first end face. The temple support comprises a second end face, two extending walls extended outwardly from two corresponding sides of the second end face, respectively, and a shaft rod provided between the two extending walls. The pivoting clip comprises a C-shaped buckle with appropriate resilience, two connecting legs connected with two ends of the C-shaped buckle, respectively, and an opening located between the two connecting legs. In this case, the C-shaped buckle is allowed for pivotally connecting to the shaft rod. The two connecting legs are tenoned into the engagement slot, and the temple support is capable of rotating with respect to the rim support around the shaft rod and the C-shaped buckle.

A spectacle structure with transformable frames is disclosed. In the spectacle structure, an upper frame and a lower frame have corresponding lens assembling parts, as well as corresponding latched holes and latches to combine the upper frame and the lower frame to one spectacle frame. When the upper frame and the lower frame are going to be separated, push resistant blocks of the upper frame can be pushed to move the latches away from the latched position. Accordingly, the upper frame and the lower frame can be separated or assembled to form half-rimmed or full-rimmed spectacles according to the user's needs.

Connection hinge for spectacles frames of the type adapted to connect the lateral sidearm of a spectacles frame to the front part of the same spectacles frame; the connection hinge being characterized by comprising: a cup-shaped body, which is structured so as to be fixed cantilevered in a rigid manner onto the lateral side of the front part of a spectacles frame, and is provided with a central cavity of substantially cylindrical shape and with a transversal, oblong, pass-through slot or cut, which extends along the lateral side of the cup-shaped body while remaining on a lying plane locally substantially perpendicular to the reference axis of the central cavity, and penetrates in the cup-shaped body up to said central recess; a central pin which has a cylindrical shape substantially complementary to that of the central cavity of the cup-shaped body, and is inserted in axially rotatable manner in the central cavity of the cup-shaped body; and a transverse locking plug which has an end rigidly fixed to the body of the central pin, and is structured so as to protrude cantilevered from the cup-shaped body engaging in pass-through and sliding manner the pass-through slot or cut present on the lateral side of the cup-shaped body, and to be rigidly fixed or incorporated on the proximal end of the lateral sidearm of the spectacles.

A rear-viewing mirror assembly for a pair of glasses having an arm, the mirror assembly includes a housing forming an inner area and configured to secure to the arm; a locking mechanism disposed within the inner area of the housing; an elongated rod extending partially outside the housing and engaged with the locking mechanism; and a mirror rigidly attached to the elongated rod.

Aspects of the present invention relate to ear horn assemblies for head worn computers.
