Abstract
The present invention is directed toward the design of a holding apparatus which allows contact lens lathes to hold contact lens buttons during the contact lens manufacturing process. The holding apparatus functions to hold lenses manufactured from a different sized stock than what the lens manufacturing equipment is designed to hold. In general the holding apparatus has a circular portion having a mating surface on a one side and a cylindrical protrusion extending from the other side. A contact lens lathe can hold the cylindrical protrusion of the holding apparatus while the mating surface mates with a surface on a contact lens button. The lens button and holding apparatus surfaces can be modified to allow more efficient machining of the lens buttons.
