Publication number: 20200409176Abstract: A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.Type: ApplicationFiled: July 14, 2020Publication date: December 31, 2020Applicant: OneFocus Vision, Inc.Inventors: Adam HARANT, Amelia DAVENPORT, Neil CRAMER, Steve WAITE, Amitava GUPTA, William J.

Patent number: 10682837Abstract: Apparatuses and methods for applying a transfer material from a transfer component onto the surface of an article are disclosed, including apparatuses and methods of transfer printing on and/or decorating three-dimensional articles, as well as the articles printed and/or decorated thereby. In some embodiments, the method may utilize a printer such as an inkjet printer. In some cases, the transfer material may be a UV curable ink and/or adhesive. When the transfer material is UV curable, the transfer component may be permeable to UV radiation to allow curing of the ink and/or adhesive therethrough. UV curable adhesives including thiol-acrylate and thiol-ene acrylate inkjet-able adhesives are disclosed.Type: GrantFiled: May 24, 2018Date of Patent: June 16, 2020Assignee: The Proctor & Gamble CompanyInventors: Karen Aida Martinez de Leon, Christopher Gerald Donner, Matthew Richard Allen, Robert Paul Cassoni, Michael Idacavage, Neil Cramer

Publication number: 20190048180Abstract: A hydrogel formulation has been developed that can be cast to form a hydrophilic cross-linked network with water content of 30-60% by weight that undergoes a volume expansion less than 5% when equilibrated in water or an aqueous solution of ionic species. This hydrogel formulation was used to cast a soft contact lens incorporating an insert that may be a sealed module filled with a fluid. Diameter of lenses cast without an insert measured within 0.5-5.0% of the target diameter after hydration. The interface between the hydrogel and the insert in lenses cast with an insert remaining stress free after hydration, when the lens was inspected under a microscope. The formulation comprises and may consist of a mixture of hydrophilic mono-functional monomers, cross-linking agents, a photo-curing catalyst and a diluent.Type: ApplicationFiled: May 7, 2018Publication date: February 14, 2019Inventors: Adam Harant, Neil CRAMER, Amelia DAVENPORT, Steve WAITE, Amitava GUPTA

Publication number: 20160167301Abstract: The use life of windows (e.g., PDMS windows) for 3D SLA printers can be been extended by the incorporation of more polar photoinitiators and higher molecular weight photoinitiators into the resin. The degradation of the window, usually seen as cloudiness, has been shown to be from polymerization of the resin within the window material, and by using either polar or high molecular weight photoinitiators that are much less soluble in the window material, the degradation from polymerization in the window can be greatly reduced, thus extending the life of the window material. The extension of use life for the window when using the photoinitiators described herein can even occur when the resin has significant solubility in the window material, which also allows use of nonpolar resins that often have advantages over polar resins (viscosity and water uptake).Type: ApplicationFiled: December 11, 2015Publication date: June 16, 2016Inventors: Michael Cole, Neil Cramer, Amelia Davenport
