Abstract: The invention relates to a device and method for directly securing at least one temple (3.1, 3.2), end-piece (3.6, 3.7) and/or bridge (3.3) of a spectacle frame (3) to at least one spectacle lens (2, 2?) of rimless spectacles (1), wherein the at least one spectacle lens (2, 2?) has at least one edge recess (5, 5?, 5?, 5??) which extends along the transverse axis (QA) of the spectacle lens (2, 2?). Particularly advantageously, in the edge recess (5, 5?, 5?, 5??) a securing body (6, 6?, 6?, 6??) is accommodated in a positively fitting manner and is firmly connected to the spectacle lens (2, 2?), wherein the securing body (6, 6?, 6?, 6??) has a bush-like receiving channel (7) extending along the transverse axis (QA), and the temple (3.1, 3.2), the end-piece (3.6, 3.7) and/or the bridge (3.3) of the spectacle frame (3) have at least one plug-like connection section (8) which can be inserted into the bush-like receiving channels (7) to produce a detachable plug-type connection.

Abstract: A rim locker for spectacle frame comprises a first portion and a second portion which are connected to two edges of lens rim in cut-off position respectively. The second portion has a screw hole for inserting a screw and the first portion is having thread to let the screw in for fastening the lens rim. The screw further has a stopping cap and the first portion further has a cylinder housing for hiding and moving the stopping cap, so that when the rim-locker is opening, the stopping cap will moving along the track of the housing, and stop at the end to prevent the screw slip off from the rim-locker and protect the screw threads not strip off easily.

Abstract: A method of calculating an individual progressive lens creates one or more basic designs for lenses based on theoretical specifications, and then creates starting designs from these basic designs. Individual progressive lenses are calculated from the starting designs corresponding to the individual data from wearing test subjects. Valid starting designs are then created for production. The individual lenses are calculated from the starting designs according to individual customer data.

Abstract: A pair of shining swimming goggles comprises a pair of swimming goggles, a shining module and an electric conducting portion. The shining module is embedded in an inner portion of the swimming goggles. The electric conducting portion is disposed on a surface of the swimming goggles. The electric conducting portion is electrically connected to the shining module, thereby when the swimming goggles are placed in water, the electric conducting portion conducts electricity to the shining module by water to make the shining module shine for showing the position of the swimmer.

Abstract: An auxiliary eyeglass is mounted frontwardly on a primary eyeglass having a primary bridge interconnecting two primary lenses. The auxiliary eyeglass includes two auxiliary lenses disposed frontwardly of and aligned with the primary lenses respectively. A coupling unit includes a hook member hooked on the primary bridge, a first threaded unit extending in a transverse direction relative to the primary bridge and the hook member and selectively connected to one of the hook member and the auxiliary lenses, and a mounting unit selectively connected to the other one of the hook member and the auxiliary lenses with the first threaded unit extending through the mounting unit. A second threaded unit is mounted threadedly on the first threaded unit and adjustably abuts against two opposite sides of the mounting unit so as to permit adjustment and positioning of the auxiliary lenses relative to the primary lenses.

Abstract: A lighted mask for underwater divers utilizing a monochromatic blue-green LED light source secured to the mask directing light to the front of the face plate of the mask and having a push button control mounted on the mask for actuating the light source.

Abstract: An eyeglass flotation assembly including a first and second resilient ear piece connector each having a curved orifice for resiliently receiving the curved end portion of an eyeglass ear piece; and a strap member secured between the first and second ear piece connectors. The ear piece connectors are constructed from a buoyant material, preferably a plastic foam. In various embodiments the strap member may include an inflatable bladder member housed within a fabric sheath; one of the ear piece connectors may include an inflation mechanism for inflating the bladder member; the other ear connector may includes a valve for adjusting the buoyancy level of the assembly by adjusting the amount of air contained within the bladder member; and the strap member may be equipped with an adjustment slide.

Abstract: Adjustable size protective eyewear in the form of visitor safety spectacles have a moveable or adjustable hinge pin coupling between the temple sidebars and the lens frame. An opening in each side of the lens frame contains multiple hinge pin sockets which are aligned at an angle with respect to the lens frame such that movement of the hinge pins from socket to socket not only increases the distance between temple sidebars but also the effective length from the lens frame to the ear piece of the temple sidebar. This arrangement allows a single pair of adjustable safety spectacles to be used by a person of a given head size with the adjustability to fit over the user's prescription eyewear where the user requires the prescription eyewear in addition to the safety spectacles.
