  • Patent number: 10082607
    Abstract: The invention relates to a method of applying an anti-reflective coating to an optical surface of a mold. In one embodiment, the method includes the steps of providing a lens mold having an optical surface; forming a layer of a super hydrophobic material over the optical surface, where the super hydrophobic material contains an amount of dipodal silane that is a relative percentage of the super hydrophobic material; forming an anti-reflective coating layered structure over the layer of the super hydrophobic material; and forming a layer of a coupling agent deposited with a monolayer thickness to the anti-reflective coating layered structure using vapor deposition under aprotic conditions or by dip coating or spin coating using a solution of a coupling agent in an aprotic solvent.

  • Patent number: 9751268
    Abstract: The present invention encompasses, in part, a method and apparatus for lens casting in which two molds, preferably formed of plastic, are interconnected or joined together via a ring to form a mold cavity having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold having a ring having an interior periphery; a front mold formed of a plastic and having a lens-forming surface, an edge circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base having dimensions greater than the interior periphery; and a rear mold formed of a plastic and having a lens-forming surface.
