Abstract: Eyewear attachments are provided that can include a bridge pad having a base extending between terminal ends and defining a perimeter, and each terminal end having a tower extending normally from the base and forming at least a portion of a top opposing the base of the bridge pad. Eyewear assemblies are provided that can include a frame having a bridge extending between two lense housings, each of the lense housings have an upper portion opposing a lower portion of the housed lense, and a bridge pad coupled to the frame. Methods of affixing eyewear in useful configuration are provided that can include, providing eyewear having a bridge pad, the bridge pad extending away from the eyewear and toward the face when the eyewear is in the worn position, and aligning at least a portion of the bridge pad below an upper portion of the orbital bone of the face.

Abstract: The present invention provides a nose support device for eyewear, the nose support device comprising an adjustable nose pad attached to a cross piece that is perpendicular to an adjustable nose pad arm, the adjustable nose pad arm attaching the nose pad to the eyewear, wherein the nose pad rests on the crook of a nose bridge of a wearer of the eyewear.

Abstract: Eyewear which is suitable for routine wear and within masks which are sealed against noxious environmental gases or penetration by water is provided by a frame made up of resilient metal parts including wires to provide the frame with a shape, which facilitates the placement of the eyewear on the head of the user while limiting the movement of the eyewear when in use so as to avoid breaking the seal of a mask inside of which the eyewear is disposed when the mask is donned by the user. The eyewear has a lens holding frame for holding lenses adjacent the eyes of the user's head and connected by a bridge across the user's nose.

Abstract: A lens connecting device and a method of connecting lenses for rimless glasses. Connecting means comprises a base plate to which a cylindrical element is provided to project, and a detent opening provided in the base plate. By pressingly inserting a shaft element into an insertion opening of the cylindrical element in a state that the cylindrical element is inserted into a circular-shaped connecting opening, the end part and the base plate can be integrated therewith. The shaft element is provided at the end part of the bracket to project, and the connecting opening is provided in the edge part of the lens. An opening is bored in the lens using the detent opening as a guide means by rotating the end part around the axis of the connecting opening.

Abstract: Lenses are provided in an assortment of frequently used prescriptions and are preground to a desired final contour. The lenses are optionally provided with a lug, temple and modern and with a split bridge member attached thereto to provided a half eyeglass assembly. Alternately, the parts may be provided unassembled. Proper lenses are selected on the basis of a prescription by a consumer and are assembled by the consumer to form a completed pair of eyeglasses. A bridge assembled from the split bridge members is adjustable to set a desired interpupillary distance. The positions of holes for attaching the bridge and lug to the lenses are line-symmetrical with respect to a vertical axis of each lens so as to allow the lens to be used as either a right or left lens.

Abstract: Magnifying spectacles for cosmetic use including a cross piece which extends across the face of the user and projecting upwardly from which are two magnifying lenses whose size is not substantially larger than that of the human eye. The crosspiece includes a bridgepiece which extends over the bridge of the nose of the user and whose apex is situated forwardly of the lenses. The crosspiece is connected at each end of the respective side arm which extends towards a position midway up the height of the ear of the user and terminates in an ear engagement portion. The ear engagement portion includes a portion which extends upwardly along the front of the ear over a substantial proportion of its height. The eyebrows of the user are thus wholly exposed and may be plucked with the aid of the magnifying lenses and a mirror. The lenses are pivotally mounted on the crosspiece and may thus be pivoted in turn away from the associated eye to permit the application of cosmetics to that eye.

Abstract: A broadband optical fiber network for conveying signals between subscriber locations and a head end. A coherent light source is used at the head end to generate signals for transmission to the subscriber locations. Successive groups of downstream optical transmission segments followed by optical separators or splitters carry the coherent light from the head end to the subscriber locations. Non-coherent light sources providing broadband optical signals are situated at the subscriber locations. Successive groups of upstream optical transmissions segments followed by optical combiners carry the broadband optical light signals to the head end.

Abstract: A multi-purpose protective eye shield having a main lens and at least one auxiliary lens attached to a universal frame which includes two temple bars and a nose support element. The frame may include a connecting bridge extending along the brow of the wearer. The auxiliary lenses are each individually coupled to the universal frame or the main lens. Associated with each auxiliary lens are individual hinges, for rotating the lenses about the hinge axis.

Abstract: In a pair of eyeglasses having a bridge joining the edges of the lenses, the nose rest includes a one-piece bow which is secured via a spacer element to a retaining and essentially rests only on the bridge of the nose. In particular, the bow, spacer element and retaining plate are portions of a one-piece shaped part, so that a wider range of adaptation options to the individual anatomical features of the eyeglasses wearer in the nose region, on the one hand, and to the eyeglasses design used, on the other hand, is possible in a simple manner.

Abstract: An eyeglass frame with a detachable frame front is disclosed. The eyeglass frame comprises a main frame structure including a main cross bar and hinged temples at its ends, and the separate, detachable frame front comprises rims interconnected by a pair of parallel cross members defining a bridge. A fastener member or pad is secured to the underside of the main cross bar and has a pair of parallel grooves cooparable with the cross members for releasably securing the latter in position. One of the grooves is along the front surface of the fastener member and the other groove lies along the lower surface thereof. The fastener member also has one or more apertures cooperable with teats on an additional (sun) frame front for releasable securing the latter. Alternatively the additional frame front may be pivotally mounted on the fastener member.
