Abstract: Disclosed herein is a method and apparatus for forming on-site tinted and coated optical elements from a mold. The apparatus is a mold having a polymer release layer; an optical coating, such as an anti-reflective coating; a coupling agent layer to bind to the optical coating and having unreacted chemical groups; and, optionally, a tinted hard coat layer having unreacted chemical groups. The mold can be shipped to a lab that prepares optical elements, such as ophthalmic lenses, after the coupling agent layer is added or after the tinted hard coat layer is added. When using the mold with a lens resin having unreacted chemical groups, the coupling agent layer, tinted hard coat layer and optical element all crosslink as the optical element is cured to form, on-site, a durable and stable lens with chemically bound optical coatings.

Abstract: An abrasion resistant, radiation or heat curable dual composition is applied to a polymer substrate, such as an opthamlic lens. An abrasion enhancement layer is deposited on a surface of the substrate. The abrasion enhancement layer has a modulus of M.sub.1 and a Shore A value of 50 or less. A top coating is deposited on the abrasion enhancement layer. It has a modulus of M.sub.2 that is greater than M.sub.1. The top coating has an abrasion resistance Bayer Haze Gain ratio of 1.0 or greater.

Abstract: A dual coating is provided for tinting a plastic material such that the plastic material is tinted and rendered scratch resistant. Also provided is tintable, scratch resistant plastic materials and tinted, scratch resistant plastic materials. The dual layer coating includes a dye reservoir layer formed over a surface of the material to be tinted and a hard coating layer formed over the dye reservoir layer. The dye reservoir layer includes between about fifteen and eighty percent by weight of a flexible acrylated oligomer or acrylated oligomer/acrylate monomer blend resin, and between about one and seventy percent by weight of a mono vinyl functional reactive diluent.

Abstract: A polymerizable composition for the production of high quality ophthalmic lenses is disclosed that includes:a) between 20 and 90 weight percent, and preferably, at least 50 weight percent, of urethane, epoxy, or polyester oligomers end terminated with acrylate or methacrylate (or mixtures of acrylate and methacrylate);b) between 5 and 50 to 80 percent, preferably between 10 and 40 percent, by weight of an optional diluent, such as a hydrocarbon diol end terminated with acrylate or methacrylate, or mixtures thereof, or a crosslinkable tri-, tetra-, or poly-acrylate or methacrylate, or mixtures thereof; andc) conventional optional additives, including but not limited to free radical initiators, UV absorbers, mold release agents, stabilizers, dyes, antioxidants, and wetting agents.The invention also includes ophthalmic lenses prepared from this composition and an apparatus for the production of lenses using sequential polymerization.

Abstract: Plastic lenses are provided wherein a tinting agent is provided within the coating to impart color to the lens. Methods are provided whereby such coatings can be applied to plastic lenses using radiation or thermal curing techniques with a plastic coating.

Abstract: A method is provided for applying a coating to an ophthalmic device by applying a coating to a face of the mold used to make the device and partially curing the coating, or, if the viscosity is sufficiently high, leaving the coating uncured. Then the liquid used to form the lens is poured into the mold and the liquid and coating are concurrently cured.
