This invention is related to a spectacle structure with transformable frames. An upper frame and a lower frame of the spectacle structure mainly have corresponding lens assembling parts. A fixing part is pivotally connected to an assembling rod of the upper frame. A connection section against the assembling rod of the upper frame is disposed in the lower frame. A carrying part of the fixing part support the bottom of the connection section. A positioning flange stops in front of the connection section to combine the upper frame and the lower frame to be as one frame. Accordingly, the upper and the lower frames can be detached to transform between a half-rimmed spectacles and a full-rimmed spectacles depending on needs.

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 optical element includes an optical lens produced by an additive manufacturing method and a holder formed at least in part with the optical lens by the additive manufacturing method. The holder is adapted for cooperation with a manufacturing machine to thereby position the optical lens at a predetermined position in the manufacturing machine. A corresponding assembly and a method of manufacturing an optical element are also described.

The present invention discloses an eyeglasses structure which comprises a frame and a lens assembly. The frame comprises a groove for engaging with the lens assembly, an inner groove wall having plural first recesses and an outer groove wall having plural second recesses staggered with the plural first recesses. The lens assembly comprises a concave portion corresponding to the plural first recesses and the plural second recesses and engaged with the groove to form at least one ventilation area and plural guiding chutes corresponding to the plural second recesses and communicated with the at least one ventilation area and the plural first recesses.

A frame for spectacles with magnifying lenses includes a magnifying eyepiece for mounting on each lens. The frame includes: a front mount including, for each lens, a respective slot extending between a central region of the nose support mount and an opposite lateral region of the mount, each slot being configured to receive a portion of a respective lens-carrying support, partially surrounding a peripheral edge portion of the lens, and fixing means for fixing the lens-carrying support which is received in the respective slot to the front mount.

The lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount, and the fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play, making the orientation of each lens adjustable with respect to the front mount.

An eyeglasses assembly includes a frame and a lens. The frame includes a frame body formed with a frame groove and two engaging grooves, and a positioning column disposed in the frame groove. The lens has a main portion formed with a lens groove and a securing groove that extends perpendicularly from the lens groove. The lens further has first and second protruding portions engaging removably and respectively with the engaging grooves. The lens is movable between an initial position, where the positioning column is disposed at an intersection of the lens groove and the securing groove, and a fixed position, where the positioning column is disposed at a distal end of the securing groove such that the second protruding portion is allowed to be disengaged from the respective engaging groove.
