A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.

An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.

The present invention relates to a spectacle frame comprising: a front face, on which the at least one lens is intended to be fastened; a first temple and a second adjusting device temple each attached on one end of the front face; and a first adjusting device intended to adjust the position of the at least one lens relative to the front face of the frame, the first adjusting device comprising at least one first positioning element intended to cooperate with at least one second positioning element of a second adjusting device belonging to the at least one lens, characterized in that the first adjusting device is arranged to define a set of relative positions of the at least one second positioning element relative to the frame disposed on a curved line comprised in an inclined plane relative to a reference plane comprising the optical axes in far vision of the eyes of a user. The present invention also relates to a spectacle lens.

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.

A frame includes: a pair of temples; a connecting bar connecting respective ends of the pair of temples; at least one hanging shaft located at a middle of the connecting bar; nose pads fixed to the hanging shaft; a slide attached to the hanging shaft for a sliding movement; a pair of lens-holding frames vertically slidable in front of the connecting bar, the lens-holding frames being each configured to hold vertically arranged upper and lower lenses; and a bridge coupling the lens-holding frames. The bridge is attached at a level lower than a center of the lower lens in each of the lens-holding frames, and the lens-holding frames are slidable for a distance at least corresponding to a distance between a center of the upper lens and the center of the lower lens.
