Publication number: 20170027236Abstract: A shirt has a lens cloth for cleaning eyeglass lenses. The shirt is particularly useful for cleaning eyeglasses and sunglasses while boating and fishing. The lens cloth is disposed on an inside surface of the shirt so the lens cloth is not exposed to dirt, rain, and sea spray. The lens cloth can be placed on the interior of the torso of the shirt. The lens cloth extends upward from the bottom hemline of the front of the shirt. The lens cloth can reach a height that is lower than the waistline of the pants of a wearer. In this way, the lens cloth does not overly the skin of the wearer and remains clear of perspiration and sunscreen. To use the lens cloth, the front tail of the shirt is folded backward to expose the underlying lens cloth. In addition, a pocket can be formed on the shirt with a lens cloth held within the pocket. The lens cloth is kept clean by folding the lens cloth into the pocket.Type: ApplicationFiled: July 31, 2015Publication date: February 2, 2017Applicant: GOGGLE EYES, LLCInventor: David B. Smith
