ABSTRACT:
Front and rear lenses of a composite eyeglass lens are laminated together by holding the front lens in an X, Y adjustable stage on a laminating axis, holding the rear lens in a predetermined position relative to the laminating axis, and moving the two lenses together on the laminating axis to spread an adhesive between them. The rear lens holder is rotatable around a laminating axis and has an adjustable center foot adhesively tacked to the rear lens and an array of surrounding pressure feet for pressing the rear lens uniformly against the front lens in a process that can be observed by the operator. Then, the adhesive between the pressed-together lenses is cured by UV radiation directed through the front lens before the lenses are removed from the laminator.
