Eyewear for releasably receiving a lens has a joint sleeve for holding the lens in place.

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.

Eyewear can be provided that comprises at least one lens, at least one earstem, and a frame with components that interconnect two or more components of the eyewear. The components can include an engagement structure of the lens and a coupling mechanism attached to the frame. The coupling mechanism can include a housing configured to receive the engagement protrusion and a lever mechanism being operative to move between open and closed positions for disengaging or engaging with the engagement protrusion.

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

A head-wearable device includes a center support extending in generally lateral directions, a first side arm extending from a first end of the center frame support and a second side arm extending from a second end of the center support. The device may further include a nosebridge that is removably coupled to the center frame support. The device may also include a lens assembly that is removably coupled to the center support or the nosebridge. The lens assembly may have a single lens, or a multi-lens arrangement configured to cooperate with display to correct for a user's ocular disease or disorder.

The invention relates to a lens exchanging structure. Lens-frame assembling parts of a glasses frame of a main spectacle frame are assembled with lens frames. Intercalating flanges on one sides of the lens frames are correspondingly intercalated by intercalating concave parts of the lens-frame assembling parts. Positioning slots on another sides of the lens frames are inserted by positioning bumps of the fixing parts in sliding slots of the glasses frame. Therefore, when the main spectacle frame or the lens frames are needed to be exchanged, it only needs to fiddle the fixing parts to separate the positioning bumps of the fixing parts and the positioning slots of the lens frames. Then, the lens frames can be removed from the main spectacle frame. The removed lens frames can be assembled with other main spectacle frames having other styles and colors.

An eyeglass lens replacement assembly is revealed. A limiting slot is formed on each side of a frame and a limiting stopper is arranged in the limiting slot. A temple pivot member is mounted in the limiting slot. A lens is mounted to a lens connection portion of the frame and two sides of the lens are inserted into insertion slots of the temple pivot members. Each side of the lens is provided with a positioning dent which is locked with a positioning bulge of the insertion slot. A limiting bulge of a positioning portion pivoted on the temple pivot member is limited in a limiting notch of the lens while a locking recess of the positioning portion is locked and positioned by an inner wall surface of the insertion slot. Thereby the frame, the temple pivot members and the lens are combined with and connected to one another firmly.
