A magnetic end effector utilizing a switchable Halbach array includes a pair of opposing members that can move towards and away from each other. The switchable Halbach arrays are located on or near the inner surface of the opposing members. A mechanical switching system is used to control the switchable Halbach arrays by moving one or more magnets that make up the switchable Halbach arrays. When manipulated in a certain way, the switchable Halbach arrays cause the opposing members to move towards each other, and when manipulate in a different manner, cause the opposing members to move away from each other.

An embodiment includes a snap-fit temple interface of a lens. The snap-fit temple interface includes a first snap-fit feature and a second snap-fit feature. The first snap-fit feature of the lens is configured to be engaged with a first corresponding snap-fit feature of a temple assembly. The first snap-fit feature is configured to be engaged with the first corresponding snap-fit feature by a first movement of the lens in a first direction relative to the temple assembly followed by a second movement of the lens in a second direction relative to the temple assembly. The second snap-fit feature of the lens is configured to be engaged with a second corresponding snap-fit feature of the temple assembly. The second snap-fit feature is configured to be engaged with the second snap-fit feature by the second movement of the lens in the second direction relative to the temple assembly. The first direction is substantially perpendicular to the second direction.

Eyewear and eyewear structures comprising bulk-solidifying amorphous alloys and methods of making eyewear structures from such bulk-solidifying amorphous alloys are described. The bulk-solidifying amorphous alloys provide form and shape durability, the minimum use of fasteners in the eyewear structure, high resistance to chemical and environmental effects, and low-cost net-shape fabrication for intricate eyewear design and shapes.

A safety system includes safety glasses and an apparatus. The safety glasses include an electronic system having a sensor configured to detect when the safety glasses are worn by a user and a wireless communication device. The apparatus includes a body housing an electrical isolation device and a wireless communication device. The body includes a first end defining a female electrical socket, a second end defining a male electrical plug and a fastening device coupled to the body and configured to move from an open position to a closed position in which an electrical cord that is electrically coupled to the body at one of the first end or the second end is also physically secured to the body by the fastening device. The electrical isolation device is configured to prevent current flow in the line conductor included in the body when the safety glasses are not being worn by the user.

An optical device for a wearer including an optical system with an active function configured to be mounted into a frame, a wafer comprising an internal face facing the optical system, the wafer being configured to be mounted into the frame, and holding means configured to maintain the optical system and the wafer in the frame without contact at least between a part of the optical system and the internal face of the wafer.

A first side of the outer shell of a spectacle lens faces away from the inner shell and forms the front side of the spectacle lens, and the first side of the inner shell faces away from the outer shell and forms the rear side of the spectacle lens. The outer shell includes the coupling-in section, the light guiding channel and the coupling-out section. The inner shell includes an opening which extends from the second side of the inner shell, which faces towards the outer shell, in the direction of the rear side and in which the light guiding channel sits. The coupling-out section lies next to the opening such that the light bundles coupled out by the coupling-out section enter the inner shell via the second side of the inner shell, run through the inner shell and leave the inner shell via the rear side.

A glasses frame structure 1 contains: a body (10), a lens assembly (20), and a fixing element (30). The body (10) includes a fixer (11) made of elastic plastic material, two extensions (14), a connection protrusion (15), a limiting groove (151), and a positioning orifice (16). The fixer (11) has two first retaining units (12), and each of the two first retaining units (12) has a fastening space (121), wherein the fastening space (121) has a first tilted face (122) and a first engagement tab (123). The lens assembly (20) includes a top fringe (21), an affix projection (23) corresponding to the positioning orifice (16) so that the top fringe (21) retains with the limiting groove (16), and the affix projection (23) engages with the positioning orifice (16). The top fringe (21) has two second retaining units (22) corresponding to the two first retaining units individually, wherein said each second retaining unit (22) has a second tilted face (226) and a second engagement tab (221).

A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens can be constructed with several shells including an outer shell and an inner shell which is joined to the outer shell, wherein a curved channel shell, which includes a curved first reflecting surface and a curved second reflecting surface, is arranged between the outer and inner shell. The light guiding channel includes at least one section of the channel shell and the two reflecting surfaces on which the light bundles are reflected for guiding from the coupling-in section to the coupling-out section.

A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens includes a front side and a rear side, a coupling-in section and a coupling-out section spaced apart from the coupling-in section, as well as a light guiding channel which is suitable for guiding light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section of the spectacle lens, in the spectacle lens to the coupling-out section, by which they are coupled out of the spectacle lens.
