## Background
BACKGROUND
For a medical professional examining or performing surgery on a patient, being able to clearly see the area of interest is critical. For this purpose, many different illumination devices and vision enhancing devices are available. Illumination devices include many different types of medical headlamps, some powered by a battery pack worn at the waist, while others are powered by a battery pack worn on the headband of the headlamp. For vision enhancement, there are eyeglasses that not only correct vision but that also magnify the area of interest. Although efforts have been made to twin eyeglasses with a light source, these devices tend to be somewhat cumbersome and expensive, with battery placement a challenging issue in design.
Although it is known to clip a flashlight to a pair of eyeglasses, the result has been suboptimal. Ideally, the light source should be positioned directly between the user's eyes, and projects light straight ahead from this position. But because the bridge of a pair of eyeglasses is generally above eye level, a simple flashlight attached to this bridge if pointed down so that the front of the flashlight is at eyelevel, will project a beam of light downwardly. Generally, and particularly in a medical setting, this is undesirable because the further a light source is from the user's interpupil region, the larger shadows it creates, thereby failing to adequately light the region of interest.
SUMMARY
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope. In various embodiments, one or more of the above-described problems have been reduced or eliminated, while other embodiments are directed to other improvements.
In a first, separate embodiment, the present invention is a lighting device, for attachment to an object structured to be worn on at least one facial feature of a human user, having a releasable fastener adapted for attachment to the above-noted object and a pole, having a first end pivotably connected to the clip, and a second end, opposed to the first end. An electric lamp is pivotably connected to the second end. Further, the pole defines an internal cavity and has battery contacts positioned to contact a battery set placed in the internal cavity. A conductive assembly is electrically connected between the battery contacts and the electric lamp, so as to power the electric lamp.
In a second, separate embodiment, the present invention is a method of providing light to an area in front of the eyes of a human user, utilizing an object structured to be worn on at least one facial feature of said human user and a light device that includes a releasable fastener and a pole, having a first end pivotably connected to the releasable fastener, and a second end, opposed to the first end, and containing a battery set; an electric lamp, pivotably connected to the second end; and a conductive assembly, electrically connected between the battery set and the electric lamp, so as to power the electric lamp. The method includes clipping the releasably fastening light device to the object and placing the object on the face of the user; and using the lamp to provide light to the area in front of the eyes of the user.
In a third, separate embodiment, the present invention is an assembly for assisting the vision of a user and including an object structured to be worn on at least one feature of the face of a human user; and a light device attached to this object, and further including a pole, having a first end pivotably connected to the bridge, and a second end, opposed to the first end and containing a battery set. Further an electric lamp is pivotably connected to the second end and a conductive assembly is electrically connected between the battery set and the electric lamp, so as to power the electric lamp.
In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following detailed descriptions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the context of this application, a “set” may include multiple elements or a single element.
In a preferred embodiment, a vision enhancing assembly 10, includes a clip 12, adapted to permit attachment to a bridge 14 of a pair of eyeglasses 16. A pole 18 is hinged (pivotably attached in one plane of movement) at a first end to clip 12. In turn a lamp 20 (which may also be referred to as a bezel) is hinged to second end of pole 18, which is opposed to the first end. Pole 18 holds a battery set 24, which is electrically connected by way of battery contacts 32 and 34, and a conductive assembly 36 to lamp 20, so as to power lamp 20. In one embodiment, an actuator 22 is available to activate lamp 20, and adjust light intensity, is present on the lamp 20. A return conductive assembly (not shown) is connected between lamp and battery contact 32, in accordance with well-known principles of electrical lighting design.
In one embodiment, conductive assembly 36 may include a pair of wires passing between pole 18 and lamp 20, to conduct electricity to lamp 20 and back to battery set 24. Alternatively, Pole 18 or lamp 20 may include a socket that accepts a mating jack from lamp 20 or pole 18, respectively. Referring to FIG. 3, in another embodiment, a contact 30 on a first portion of the hinge between pole 18 and lamp 20, makes contact with a facing arcuate contact 28 on an adjacent portion of that hinge. As the hinge is rotated, electrical connection is maintained.
In one embodiment battery set 24 is a stack of cell batteries, of the type commonly used to power watches and other articles where space is at a premium, and having a diameter of between 8 mm and 14 mm, depending on the exact type of cell battery. In one embodiment, more specifically, ANSI 1166A(L) batteries are used. In an additional embodiment, a AAA battery is used. In one embodiment batteries 24 are rechargeable, with, for example, the socket for connecting to the jack from the lamp also serving as a recharging port. In an additional embodiment pole 18 opens to permit replacement of batteries. In yet another embodiment, pole 18 is produced integrally with the battery set, and is made for a single use only. In one variant of this embodiment the hinges are made to snap apart (or otherwise come apart), to permit easy replacement of pole 18. In a further embodiment, assembly 10 further includes a set of alternative lamps 20, to provide differing light intensities, colors and other varying light characteristics, per user choice. This is particularly efficient in the embodiment in which the lamp 20 snaps off pole 18. Lamp 20 generally includes a high efficiency light source, such as a light emitting diode (LED).
In one embodiment, assembly 10 does not include a clip 12, but is integral with the pair of eyeglasses 16, and is defined as including eyeglasses 16. Many different clip 12 types fall within the scope. For example, in one embodiment, clip 12, includes a threaded element that can be tightened to press against the bridge 14, to keep the assembly 10 securely in place. In another clip 12 type, metal that is resiliently deformable is used, to grip the bridge 14. Further, instead of clip 12, a magnet may attach assembly 10 to a magnetic spot on eyeglasses 16. In further embodiments, assembly 10 is attached releasably in some embodiments, permanently in others, to some object other than a pair of eyeglasses, that is structured to be worn on at least one facial feature of a human user, an ear harness, for example or a headband.
While a number of exemplary aspects and embodiments have been discussed above, those possessed of skill in the art will recognize certain modifications, permutations, additions and sub-combinations thereof. It is therefore intended that the following appended claims and claims hereafter introduced are interpreted to include all such modifications, permutations, additions and sub-combinations as are within their true spirit and scope.
