Abstract: A very low inventory method of making eyeglasses. Two lens elements having special complementary surfaces are provided. These lens elements can be positioned relative to each other to provide wide ranges of focus correction and astigmatism correction. Various preferred embodiments of the invention are described. In one embodiment the required inventory is only identical sets of two complementary lenses for providing correction for almost all needed eye correction for a typical population. In this embodiment, the lens units are first adjusted relative to each other to provide a desired focusing power. Astigmatism may be corrected by a small adjustment in a second direction perpendicular to the first direction followed by a rotation of the two lenses about the axis of the two lenses. When the adjustments have been made the two lenses are fixed with respect to each other and installed in eyeglass frames. Cutting to the shape of the eyeglass frames can occur either before or after the fixing.

Abstract: In a particular embodiment, an eyeglass device is disclosed that includes a first frame member including a first frame member front that will often hold at least one corrective first lens and including a first end portion adapted to couple to a first temple. The eyeglass device further includes a second frame member having a second frame member front to hold at least one corrective second lens. The second frame member is adapted to associate with the first frame member via a magnetic coupling associated with the first end portion to secure a position of the at least one second corrective lens relative to the at least one first corrective lens to achieve a desired focal power.

Abstract: Adjustable focus eyeglasses with two lens units, each lens unit having two lens elements. The eyeglasses are focused by adjusting the position of at least one of the two lens elements relative to the other in a direction generally perpendicular to a viewing direction. The relative motion can be linear or pivotal about a pivot location outside the lenses.

Abstract: A nose pad assembly is slidably mounted to an eyeglass frame by which a pair of multifocal lenses are held. The nose pad assembly includes a pair of oval nose pads within which elongated guide grooves are defined. Two pairs of upper and lower magnets are coaxially and fixedly mounted in the upper and lower ends of the respective nose pads. A pair of slides are slidably moved along the guide grooves and attached to a pair of pad arms of the eyeglass frame. The slides include a corresponding pair of slide magnets positioned within the respective guide grooves. The slide magnets are selectively attracted to the upper and lower magnets to hold the eyeglass frame in its upper and lower positions, respectively. A bridge member extends between the upper end of the nose pads. The bridge member is configured to resist a substantially vertical force which may be applied thereto when the eyeglass frame is moved between its upper and lower positions.

The mechanism generally includes a boss attached or hooked onto the bi-focals, said boss comprising a hollow sleeve aligned vertically. An elongate slider is slidably carried in the boss, and a nose rest is attached at the lower end of the slider. A set screw is threaded frontally into the boss and is tightenable against the slider. The slider can be adjusted along a continuous range of elevations and locked into any of said positions by tightening the set screw, thereby facilitating adjustment of the nose rest. A mechanism for temporarily attaching a singularly adjustable nose-rest to any standard bi-focals, comprising an internally threaded tube, adjusting yoke, and spring support member.

Abstract: A method and apparatus for protecting removable markings on an optical lens during grinding thereof to a desired prescription. A mask is placed over the markings prior to application of an adhesive tape, to which a low temperature alloy block is bonded for holding of the lens during grinding. The mask preferably covers only the markings, and is transparent to allow alignment thereof. Preferably the mask is held in place on the lens surface without the use of an adhesive, although a low tack adhesive may be used which does not remove the markings when the mask is peeled away from the lens. A preferred material for the mask is a static cling vinyl.

Abstract: Multi-focal prescription composite lenses having at least two corrections are made by adhering a first-part lens having a predetermined positive or negative diopter correction realized by a cylinder correction prescription on a rear surface and a preselected front surface, to a second-part lens having a predetermined prescription correction at a portion of a front surface and a preselected rear surface that is complimentary to the front surface of the first lens. A lens attachment feature, normally a tab, is integral with at least one of the first- and second-part lens, and persists in the multi-focal prescription composite lens. An eyeglass frame has and presents a complimentary feature, normally a channel within a front piece to the frame, that engages and holds the multi-focal prescription lens to the frame at an adjustable pupillary distance. Two composite lenses are assembled, and permanently mounted in and to the frame, totally without power tools.

A pair of movable magnets are attached to the sliding members. A pair of fixed magnets are attached to the upper ends of the nose pads and adapted to cooperate with the movable magnets so as to lock the eyeglass frame or lenses in a raised position. Another pair of fixed magnets are attached to the lower ends of the nose pads and adapted to cooperate with the movable magnets so as to lock the eyeglass frame or lenses in a lowered position.

Abstract: A device positioned on the nose of a wearer of eyeglasses with bifocal lenses having the lens lower parts corrected for near vision. The device includes a housing that defines a nose cavity having an inner surface defining a matrix for receiving the upper nose portion of the nose of the wearer of the eyeglasses.

The housing includes a convex surface for supporting the lens bridge and the inner sides of the two lens rims. A keeper structure connected to the housing holds the eyeglasses in position relative to the housing.

Abstract: Adjustable bifocal spectacles having at least one pair of lenses mounted in an upper frame vertically movable in relation to a lower frame so that the focal length may be changed by raising and lowering a pair of lenses in the sight line of the viewer. Means are provided for applying a pressure to the upper and lower frames either at opposite ends of the frames or at the nose support and bridge to raise or lower the upper frame in relation to the lower frame, the pressure being symmetrical with respect to the nose and bridge. Vertical movement of the lenses is accomplished by actuating a mechanism at one side or at opposite sides of the lens frame, either mounted directly to the lens frame or mounted in modified temples so that the spectacles may be adjusted without placing the hand in front of the face.

Abstract: The eyeglasses include a pair of rims carrying bifocal lenses and interconnected by a bridge to define a nose-receiving space therebetween and further includes a nose piece, mounted between the rims, either as an integral part of the bridge or as part of a separate, detachable unit. The nose piece is connected to a push-push mechanism which is arranged so that a wearer, with the nose piece resting on his nose, can conveniently move the lenses up and down between a normal position and raised a position where the lower reading portions of the lenses are in front of the eyes by simply applying a momentary downward force on the bridge, the rims or the temple pieces.

Abstract: This invention relates to spectacles' frame wherein its wearing position relative to the face of the user can be adjusted accurately by moving the nose pads vertically. When this frame is used for spectacles embodying multifocal lenses, including the portions for long distance viewing and the portions for near distance viewing, its wearing position can be changed upwardly so that the portions for near distance viewing are in alignment with the eyes of the user, thereby to afford the user longtime viewing with reduced fatigue. When the said frame is used for spectacles with monofocal lenses, its wearing position can be adjusted upwardly or downwardly so that the focal points of lenses are in correct alignment with the eyes of the user.
