Abstract:
A method for curing a lens-forming fluid, comprising the steps of:a. placing the lens-forming fluid in a molding cavity from a supply of the lens-forming fluid, the molding cavity being defined by a front mold, a rear mold and a gasket, wherein the gasket has a first end and a second end, a body portion joining the first end and the second end and having an outer surface, a bore extending axially through the body portion for receiving the front mold and the rear mold, the bore having a longitudinal axis, and at least one port formed intermediate the outer surface of the body portion and the bore, the port being separated from the ambient air by the outer surface of the body portion and being in fluid communication with the molding cavity, and wherein the lens-forming fluid from the supply of the lens-forming fluid is placed into the molding cavity through the port;b. terminating fluid communication between the supply of the lens-forming fluid and the port; andc. exposing the lens-forming fluid to an ultra-violet light for a desired time, thereby curing the lens-forming fluid.
