Abstract: A lens mold cavity is formed and then evacuated via a vacuum channel contained within a mold member. A fluid valve is opened to expose the lens mold cavity to liquid lens material, whereby a vacuum of the lens mold cavity draws the liquid lens material to fill the lens mold cavity. The fluid valve is then closed and the liquid lens material within the lens mold cavity is cured to obtain an opthalmic lens such as a contact lens.
