ABSTRACT:
FIELD OF INVENTION
This present invention relates to improved temporary glare shields for eyeglasses and the like, and more particularly to glare shields in the form of inexpensive, disposable, lightweight thin plastic film having a shape and size that fits all shapes and sizes of eyeglasses and the like. This invention is self-adhered to eyeglasses and the like, and contains properties of tint that filter harmful UV and infrared rays, and provides complete peripheral protection from all potential sources of harmful sunlight properties, glare, airborne hazards, insects, contaminants and toxins. It may also be adhered directly to the face to protect eyes of persons not wearing eyeglasses.

Lens Cover System
Of the many attempts made to convert existing eyeglasses into sunglasses, all fall short in providing complete, low-cost, practical, and convenient temporary sun shield protection, particularly in those areas of peripheral vision above and below eyeglass frames, as well as at the temporal sides. Some efforts disclose special attempts to remedy certain potential visual problems present in the workplace or resulting in prolonged computer use. One attempt has to do with half-lenses that is inadequate when applied to other lenses. And, in other cases, non-transparent “side-blinders” are employed to shield bright light, airborne objects and other contaminants. In many such efforts temporary shields are used that only protect the limited area of host eyeglass lenses, allowing other surrounding regions to be exposed to the aforementioned hazards. And, in many cases, these efforts offer impractical solutions that are unaesthetic and bulky, and prove to be highly inconvenient.
For example, U.S. Pat. No. 111,494 to E. K. Madan on Sep. 27, 1938 discloses a design for sunglasses that is permanently attached to a spectacle frame, having front and side shade members. The disadvantage with this Madan invention is that it adds a disproportionate amount of weight to the front of the spectacles and would likely cause them to slide down the nose of the wearer. This potential problem would require frequent adjustment to maintain the proper positioning of spectacles on the face of wearers. The added device is permanently attached and cannot be conveniently removed when not needed. This Madan invention appears to be costly and is obviously not disposable. Although this devise shields areas in the front and sides, there are certain areas where sunlight will impact eyesight from above and below the frames. When assembled, this device cannot be stored in a conventional eyeglass case.
Another example, U.S. Pat. No. 2,388,626 to E. I. Wilson on Nov. 6, 1945 discloses an eyeglass shield in which the shield members are attached to the top of spectacle frames by a metallic hinge that allows adjustment to any angle or tilt. This Wilson invention is described as being composed of flexible sheet material, transparent, opaque or translucent and in another instant it is described as colored transparent material that shields the wearer from undesirable light rays.
Significant differences exist between this Wilson invention and my invention. For example, the Wilson sunshield is not a temporary device, and is not disposable because of its permanent attachment to eyeglass lenses. The added cost of this permanent attachment by itself makes this device not disposable when temporarily used as a sunshade.
In addition, considerable weight is added to the front of host eyeglasses that undoubtedly would cause this assembled device to slide down the nose of wearers and require frequent adjustment to maintain its proper position. The present invention does not create disproportionate weight to be added to the front of eyeglasses.
Another example, U.S. Pat. No. 2,511,329 to E. Craig on Jun. 13, 1950 discloses a lens shield consisting of thin flexible transparent material that is stuck to a spectacle lens to reduce glare and undesirable rays of the sun. It is adhered to eyeglass lens by an adhesive on one side of said material so that it conforms to the shape of the lens. Craig's disclosure states that this shield may be removed when not needed and carried in a packet with other shields to be used again.
A tab is described that is positioned on each shield to single-out each layer of shield in the packet. But, the likelihood of these shields sticking together exists, as the adhesive needed for each shield within the packet has no differentiation to identify the top shield being removed from others beneath it in the packet. This creates a potential problem of lifting several shields from the top of the stack when only one is needed, even though the top tab is grasped,
And, since left and right eyeglass lenses are rarely the same shape, and are instead a mirrored image of each other, two such packets are required. One of these will contain left side shields and the other will contain right side shields. A potential problem of left and right shields becoming intermingled exists.
It should be noted that the present invention provides left and right side glare shields that are individually stowed in a handy pocketsize folder comprised of a set of two. There is never a problem of several glare shields sticking together. These are a shape and size that substantially fit all shapes and sizes of eyeglasses.
Yet another disadvantage with the Craig invention exists with the likelihood of glare entering eyesight from above and below eyeglass frames in the front as well as at the side temporal areas. The present invention provides complete glare protection above and below eyeglass frames and without a breach continues this protection at the sides around each temporal area.
Another example, U.S. Pat. No. 2,714,717 to A. D. Allman on Aug. 9, 1955 discloses a glare shield and eye shade for spectacles that are clipped on to eyeglasses that contain a hinge assembly that allows them to be raised or lowered when shielding glare. The Allman invention claims us
