Combination Glasses and Glass Case

The instant invention is directed to compact cases for conventional and foldable glasses, and more particularly to a case that is non-intrusive and easy to carry on the person.

Spectacles or as commonly referred to as glasses have been around for a considerable length of time for the visually impaired. Glasses have been made as small as practical or have various foldable elements to reduce the physical size for carry around convince.

Foldable glasses include frames that fold in the middle and temples that fold at one or more locations along their length to reduce the physical size of the glasses for transport.

Typical state of the art compact folding glasses can be found in the following United States Patents: U.S. Pat. No. 2,419,303 issued to inventor W. G. Vasey on Apr. 22, 1947 which includes folding frames and temples; U.S. Pat. No. Des. 165,721 issued to M. Rand on Jan. 22, 1952 which shows folding frames and temples; U.S. Pat.
