Abstract: A pen-shaped spectacles repair kit includes a pen-shaped body having a two-sectioned case and a cap, and a screwdriver. A rear inner end of the case opposite to the cap is formed into a space for holding some spare parts for spectacles; the screwdriver has a middle body having two blades projected from two ends thereof. The screwdriver is fitted in the case by inserting the middle body into a fixing hole provided at a front end of the case, so that the screwdriver turns when the case is turned. The cap closed to the front end of the case completely covers the projected blade, and a clip provided on the cap allows the pen-shaped spectacles repair kit to be clamped on a user's pocket and conveniently portable for tightening screws on the spectacles at any place and any time.

Abstract: A portable replacement for eyeglass nose pads and arm posts. The invention is a pair of tubes, made of flexible plastic tubing. The tubing can be padded for additional comfort. The padding can also be contoured to better fit against a user's nose. The tubing is designed to fit over the posts that remain after the nose pad is broken off, or they can be placed directly on the lens if the post is broken too. The tubes are friction fit over the lens or posts. Once the tubes are in place, the user may wear the eyeglasses until they can be brought to a repair shop. The tubes can be cut to any desired length as needed. Moreover, several diameters of tubing can be provided to ensure a proper fit on any given lens or set of posts.

Abstract: A clamping tool includes a clamping member with a tubular body and resilient clamping jaws extending integrally from the tubular body and cooperatively defining a clamping hole. The clamping jaws have inclined outer surfaces which incline radially and outwardly in a direction away from the tubular body. An adjustment sleeve is sleeved on the tubular body, and has a depressing section disposed proximate to the clamping jaws, and a threaded section that is formed with an internal screw thread which engages an external screw thread on an outer surface of the tubular body. Due to the engagement between the internal screw thread and the external screw thread, the depressing section is moved along the inclined outer surfaces of the clamping jaws, and depresses the clamping jaws to permit adjustment of size of the clamping hole when the adjustment sleeve is rotated about the clamping member.

Abstract: A folder has rectangular walls that have a length and width that are approximately the same as the length and width of a credit card. An interior surface of one of the walls has a mirrored surface. Nested within an interior surface of the other wall are a screw driver, a magnifying glass, a cleaning fluid container and a tube with hinge screws therein. Additionally, a pair of nose pads are adhesively connected to the other wall.

Abstract: A method for applying a bus bar to the peripheral edge region of a shaped substrate is disclosed. The method involves: 1) applying a protective coating to a blank substrate; 2) edging the blank substrate to shape; 3) applying a conductive coating to the peripheral edge region of the shaped substrate; and 4) removing the protective coating, along with excess conductive material.

Abstract: An optical non-contact method of reading the three-dimensional shape of a profile in accordance with the luminous section principle consists of scanning the profile with a plane light beam intersecting the profile transversely, simultaneously reading the trace of the plane light beam on the profile by means of an optical receiver having an optical pointing axis at a constant non-zero pointing angle to the light beam at a series of positions along the profile, and deducing the three-dimensional shape of the profile from the readings effected at these various positions. On each reading, the light beam whose trace on the profile is read by the optical receiver is chosen from a plurality of predefined light beams which can be activated alternately. The non-contact optical reading method is particularly suitable for reading the three-dimensional shape of the inside edge of a spectacle frame rim, known as the bezel. A specific device is used to implement the method in this particular application.

Abstract: A beveling operation is applied to a spectacle lens to blunt the sharp edges of its contour. Compensation means having a capacity for elastic deformation are operative between an active periphery of a beveling tool and its support shaft during the beveling operation. Applications include numerically controlled grinding machines.

Abstract: An eyeglass screwdriver has a generally cylindrically shaped body having a first end and a second end with a driver head attached to the first end of the body for screwing in and out screws. A swivelable and rotateable head at the second end allows pressure to be transmitted to the body and driver head. The swivelable and rotateable head includes a ball, a retainer, and a cap to affix the head to the body. The preferred embodiment has the cylindrical body with a bore on axis to the body and a bore perpendicular to the axis of the cylindrical body located so that it intersects the bore on axis of the cylindrical body and further includes a spherical depression on the opposite end of the cylindrical body. There is also a magnet located in the bore to help hold the driver head.

Abstract: An assembly jig, and method for assembling a clip-on eyeglass accessory, such as clip-on sunglasses, which is custom-made for a pair of eyeglasses, such as prescription eyeglasses. The accessory is made from two lenses, a lower clasp attached to the edge of each lens, and a unitary upper bridge piece which further includes an elastic bridge with an upper clasp on either end. The clasps are hook-shaped to hold onto eyeglasses by the spring force of the bridge. No accessory frame is needed because the four clasps attach directly to the lens. To assemble the accessory with the bridge and lower clasps in the correct assembly positions the jig makes use of lens holders. These lens holders are the same as those on which the accessory lenses have already been shaped in outline so as to match the outline of the eyeglasses. The lens holders are mated with respective lens mounts on the jig, and the jig permits adjustment of the distance between the mounts and the angles of the mounts.

Abstract: Adjustable pairs of eyeglasses are disclosed which retain the precise adjustments during long periods of wear. Apparatus and methods are provided for so adjusting rim separation at the bridge of the frame of the eyeglasses and for so adjusting the effective length of temples between shoulders and bow of the frame.

Abstract: A technique for correcting defects in lens surfaces caused during lens formation. During the formation of a plastic lens, a low melting point alloy block is applied to the convex surface of the lens to hold the lens for working and machining. Upon removal, a defect in the lens surface, such as distortion, warping or aberration may appear in the area which was beneath the low melting point alloy. Accordingly, the lens is treated by subjecting it to microwave energy until the defect is removed from the lens surface, thereby reducing waste in the lens forming process.
