A plastic lens comprising a primer layer and a hard coat on at least one surface of a plastic substrate is also disclosed. The primer layer is manufactured by using the primer-forming composition. | 03-12-2009 |
20090141236 | Coatings for Ophthalmic Lens Elements - The present disclosure provides a method of forming a removable protective coating on a hydrophobic surface of an ophthalmic lens element. The method includes providing an ophthalmic lens element having a hydrophobic surface. A non-aqueous coating composition is applied so as to coat at least part of the hydrophobic surface. The composition includes a film forming coating polymer and a compatible non-aqueous solvent. A substantial portion of the solvent is removed from the composition to form a removable protective coating on the ophthalmic lens element that adheres to the hydrophobic surface. The disclosure also provides a removable protective coating, and an ophthalmic lens element having the coating. | 06-04-2009 |
20090257022 | SPECTACLE LENS AND METHOD FOR PRODUCING THE SAME - The disclosure relates to a spectacle lens comprising: a lens base member; a multi-layered anti-reflection film placed on the lens base member, and including a layer mainly made of silicon dioxide as an outermost layer; and a water-and-oil repellent layer provided in contact with the outermost layer of the multi-layered anti-reflection film, and made by using, as raw materials: at least one kind of a first fluorine-substituted alkyl group-containing organosilicon compound and a second fluorine-substituted alkyl group-containing organosilicon compound. The disclosure also relates to methods of producing a spectacle lens that is capable of retaining a sufficient water-and-oil repellency over an extended period, and having sufficient edge processability. | 10-15-2009 |
20090273756 | Process To Mold A Plastic Optical Article With Integrated Hard Coating - Disclosed is a process for molding plastic optical articles with a hard coated film, comprising steps of coating one side of an optical film with a hard coating, pre-curing the hard coating to a tack free state while still maintaining the coating flexibility, making an insert from the coated film for the desired optical article, molding the plastic resin onto the insert through insert injection molding, and post-curing the molded article. The utilization of the pre-curing and post-curing steps have been found to eliminate hard coating cracks during the insert making and the molding step, while providing a hard coating with desired properties. Such an optical article possesses a hard coating integrated on its surface, thus, eliminating the need to further coat the optical article. | 11-05-2009 |
20100007847 | PROCESS FOR MANUFACTURING A SERIES OF OPHTHALMIC LENSES AND SHEET OF FILM USED IN SUCH A PROCESS - According to a process for manufacturing a series of ophthalmic lenses, each lens consists of a substrate and a film portion ( | 01-14-2010 |

20100201940 | Surface modification of hydrophobic and/or oleophobic coatings - A hydrophobic and/or oleophobic coating system having a reversibly reduced hydrophobicity. A hydrophobic and/or oleophobic coating is applied to and is bonded or otherwise strongly adhered to a substrate, such as an optical lens. The coating has sufficient thickness to provide a weakly adhered, excess portion that is mechanically removable. The excess portion of the hydrophobic and/or oleophobic coating has a surface that is modified to reduce hydrophobicity, such as by ion bombardment. The hydrophobicity of the coating is restored by mechanical removal of the excess portion of the coating. | 08-12-2010 |
