Abstract
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.
