Patent number: 10359643Abstract: A Free-form contact lens and method of making the same. The lens includes a posterior optical quality surface having a concave shape, an opposing anterior surface having a convex shape both of which join at a lens edge that defines an outer periphery of the contact lens, and at least a first lens feature having a predetermined shape and made of a first polymerized Reactive Mixture. The remainder of the lens is made of a second polymerized Reactive Mixture that is different than the first polymerized Reactive Mixture, and that is covalently bonded thereto.Type: GrantFiled: December 18, 2015Date of Patent: July 23, 2019Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Christopher Wildsmith, Peter W. Sites, Mukul Kanaujia, Joe M. Wood

Patent number: 10355155Abstract: A method of producing an optical element, which includes a glass substrate and a sheet-like formed body, is provided. The sheet-like formed body is formed of an organic resin, one surface of which has a fresnel lens pattern and the other surface of which is bonded to the glass substrate. The sheet-like formed body is a thermoplastic polymer composition. A bonding surface of the sheet-like formed body facing the glass substrate is treated by irradiating active energy. A bonding surface of the glass substrate facing the sheet-like formed body is bonded to the bonding surface of the sheet-like formed body by using a silane coupling agent as a crosslinking agent.Type: GrantFiled: December 26, 2014Date of Patent: July 16, 2019Assignee: KURARAY CO., LTD.Inventors: Koji Abe, Shinji Hiramatsu, Katsuhiro Fujita

Patent number: 10246541Abstract: A method for making a biodegradable ophthalmic lens includes steps of mixing poly[bis(methacrylate)phosphazene], hydrophilic monomers, and a photoinitiator to form a mixture; feeding the mixture into a mold, and heating or exposing the mixture to ultraviolet radiation, thereby causing the poly[bis(methacrylate)phosphazene] to function as a cross-linking agent. Such cross-linking agent undergoes a polymerization reaction with the hydrophilic monomers and the photoinitiator to form a polyphosphazenes hydrogel; and the polyphosphazenes hydrogel is then removed from the mold.Type: GrantFiled: April 18, 2017Date of Patent: April 2, 2019Assignee: MiiCs & Partners (Shenzhen) Co., Ltd.Inventor: Hsiu-Wen Chien

Patent number: 10247859Abstract: A virtual curved surface display panel and a display device are provided. The virtual curved surface display panel includes a flat display panel having a plurality of pixels arranged in a matrix, and an array of convex lenses arranged on a light exit surface of the flat display panel. The array of convex lenses makes a track of image distances of the pixels form a curved surface. By adjusting the focal lengths of the lenses, the image distances of the pixels in the flat display panel can be various. The images of the pixels are then distributed on a curved surface. A visual effect of a virtual curved surface can be achieved with a flat display panel, improving the effect of visual impact.Type: GrantFiled: February 20, 2017Date of Patent: April 2, 2019Assignee: BOE TECHNOLOGY GROUP CO., LTD.Inventors: Jian Gao, Xiaochuan Chen, Yafeng Yang, Jifeng Tan, Pengcheng Lu, Qian Wang, Can Zhang, Can Wang, Xinli Ma, Wei Wang

Patent number: 10226884Abstract: Disclosed are a visor and a method of making the same. The method includes 1) preparing molds and molding material, 2) performing a primary injection molding, and 3) performing a secondary injection molding. According to the method, the first part and the second part are independently made on an injection mold, therefore the hardness of the first part and the second part can be made to be different so that the visor body consisting of the first part and the second part has different hardness at different positions. The disclosure further includes a visor, comprising a visor body which is composed of a first part and a second part, where the hardness of the first part is less than that of the second part.Type: GrantFiled: December 28, 2015Date of Patent: March 12, 2019Inventor: Yi Shiang Chan

Patent number: 10209534Abstract: A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error.Type: GrantFiled: July 6, 2016Date of Patent: February 19, 2019Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Azaam Alli, Dola Sinha

Patent number: 10042248Abstract: An illumination optical unit for a mask inspection system is used with EUV illumination light. A hollow waveguide of the illumination optical unit serves for guiding the illumination light. The hollow waveguide has an entry opening for the illumination light and an exit opening for the illumination light. An imaging mirror optical unit, arranged downstream of the hollow waveguide serves to image the exit opening into an illumination field. This results in an illumination optical unit, the throughput of which is optimized for the EUV illumination light.Type: GrantFiled: August 14, 2015Date of Patent: August 7, 2018Assignee: Carl Zeiss SMT GmbHInventors: Markus Degünther, Thomas Korb
