Publication number: 20040049826Abstract: An apparatus for shielding a human eye of a patient while allowing the human eye contact with the air. A lens of the apparatus is fashioned to one or both of the eyes and is optically clear and optically correct in that it does not distort the patient's vision. The optically correct aspect of the lens is achieved by either polishing a mold for the lens or alternatively, by die-cutting the lens from an optically correct material. The lens may be held in place by an adjustable strap. A plurality of vents to allow the eye contact with the air are a plurality of apertures in the lens or a plurality of spaces or holes in a cushioning structure, where the cushioning structure is coupled to the perimeter of the surface of the lens facing the eye.Type: ApplicationFiled: July 18, 2003Publication date: March 18, 2004Inventors: Henry Welling Lane, Ronald L. Underwood

Patent number: 5423712Abstract: An apparatus for custom cutting clip-on sunglasses includes a first holder for securely holding eyeglasses and a second holder for securely holding clip-on sunglasses. A first locator assists in positioning the eyeglasses on the first holder. A second locator is used for positioning the sunglasses on the second holder. A support carries a guide for tracing the perimeter of the eyeglasses and a cutter for cutting the clip-on sunglasses. To custom cut the clip-on sunglasses, the eyeglasses are positioned on the holder and each lens of the eyeglasses is marked at a point aligned with a respective locator on the holder. The clip-on sunglasses are then clipped onto the eyeglasses, and the points on the sunglasses positioned over the marks on the eyeglasses are marked. The clip-on sunglasses are then positioned on a second holder. The guide is then moved around the perimeter of the eyeglasses. The cutter moves with the guide such that the cutter cuts the sunglasses into the shape of the eyeglasses.Type: GrantFiled: August 11, 1993Date of Patent: June 13, 1995Inventors: Ronald L. Underwood, Alan W. Brown
