Smart glasses are provided in the present disclosure, including a housing, a fixing bracket, a left lens barrel, a right lens barrel, an object distance adjustment mechanism including a left-eye object distance adjustment gear, a right-eye object distance adjustment gear, an object distance adjustment driving gear engaged with the left-eye object distance adjustment gear and the right-eye object distance adjustment gear and a driving motor driving the object distance adjustment driving gear to rotate and being capable of moving back and forth on the fixing bracket along a second direction; a pupil distance adjustment mechanism connected to at least one lens barrel, and configured to drive the lens barrel to move in the first direction when an external force is applied, and a linkage member arranged between the at least one lens barrel and the driving motor.

A device for mutually fixing component parts of a frame for spectacles includes a first fixing element which is connectable by a sliding coupling inside a second fixing element and locking means, active between the first and second fixing elements, transversely to the coupling direction. The first fixing element includes at least a first seat which slidingly receives a respective first magnet, the second fixing element includes a second magnet and a second seat. The second seat configured to receive, with reduced connection play, a portion of the first magnet when it is moved, with partial extraction from the first seat, by the magnetic attraction force between the first and second magnets produced by mutual positioning of the first and second magnets with opposite magnetic polarities so that the first magnet, by engaging the first seat and the second seat, prevents relative movement between the first and second fixing elements.

The rim frame and the lens are continuously restrained to each other over a range other than the gap to stabilize holding of the lens while attachment and detachment of the lens can be facilitated by expanding a gap as consolidating the gaps in the two places into one place due to the deflection of the rim frame and movement of the lens in the left-right direction, whereby the lens can be easily attached and detached without using a tool such as a screwdriver, while can achieve holding stability when fixing the lens and ease of attachment and detachment.

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.

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.

Disclosed is a spectacle frame including a pair of lens holding rims interconnected by a bridge, each rim being encircling and holding a lens in a central aperture of the rim, each rim being linked laterally to a temple, each rim having at least one cut allowing expansion of the central aperture or retraction and closure of the central aperture by closing the cut. The spectacle frame further includes a lock allowing closure and locking the cuts of the rims. The bridge attaches to the rims to allow attachment of one bridge chosen among bridges having different shapes and/or sizes and/or decorations to adapt the spectacle frame to different morphological features of wearers and/or to choices of the wearers, and wherein the rims and the bridge includes complementary bridge connector to attach and connect the bridge to each rim. A kit of parts and an eyewear are also disclosed.

Smart glasses are provided in the present disclosure, including a housing, a fixing bracket, a left lens barrel, a right lens barrel, an object distance adjustment mechanism including a left-eye object distance adjustment gear, a right-eye object distance adjustment gear, an object distance adjustment driving gear engaged with the left-eye object distance adjustment gear and the right-eye object distance adjustment gear and a driving motor driving the object distance adjustment driving gear to rotate and being capable of moving back and forth on the fixing bracket along a second direction; a pupil distance adjustment mechanism connected to at least one lens barrel, and configured to drive the lens barrel to move in the first direction when an external force is applied, and a linkage member arranged between the at least one lens barrel and the driving motor.

A head-mounted display apparatus configured to be worn by a viewer. The apparatus includes a pair of display modules moveably coupled to a curved rail, the display modules configured to project stereoscopic images toward the viewer, wherein a first one of the display modules projects a first stereoscopic image and a second one of the display modules projects a second stereoscopic image, the first and second stereoscopic images creating a single unified virtual stereo image that converges at a predetermined convergence distance in front of the viewer. The apparatus further includes an adjustment mechanism configured to move each of the display modules along the curved rail symmetrically about a midpoint of the rail, thereby varying a distance between the display modules while maintaining the predetermined convergence distance.

A display apparatus includes: a first lens barrel in a bottomed barrel shape and including, at the bottom, a first display that displays an image; a second lens barrel in a bottomed barrel shape and including, at the bottom, a second display that displays another image; a support member elongated in an arrangement direction of the first and second lens barrels, and supporting, by passing through the first and second lens barrels in the arrangement direction, at least one of the first and second lens barrels to allow the at least one lens barrel to move in the arrangement direction; and temple parts respectively connected to two ends of the support member in the arrangement direction. The first lens barrel includes first and second sound pickup devices, the second lens barrel includes third and fourth sound pickup devices, and the temple parts respectively include fifth and sixth sound pickup devices.

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.
