Patent number: 8870371Abstract: Provided is a colored contact lens in which a colored band is disposed at a boundary part between a dark part and a white part of an eye, and a density is gradually changed from the dark part to the white part of the eye such that the density of this colored band decreases from an inner circumference side to an outer circumference side. As a result, a novel colored contact lens is provided with which it is possible to bring out beauty of the white part of the eye, which has been ignored by conventional technology, while an impression is maintained that is as natural and elegant as possible by avoiding an artificial impression such as that found in conventional technology.Type: GrantFiled: June 17, 2011Date of Patent: October 28, 2014Assignee: Menicon Co., Ltd.Inventors: Ichiro Ando, Yuji Goto, Ryo Matsushita, Kazuharu Niwa

Patent number: 8662662Abstract: A contact lens for treating binocular diplopia, the contact lens comprising: a central region adapted to degrade light passing therethrough, so as to create a central scotoma in a patient's eye in which the contact lens is placed in use; and a peripheral region adapted to degrade light passing therethrough to a lesser extent than in the central region, or not at all; such that, in use, an image in the field of view of the said eye is degraded only in the center or to a greater extent in the center than in the periphery. Also provided is a method of manufacturing such a lens, and a method of treating binocular diplopia comprising applying such a lens to a patient's eye.Type: GrantFiled: August 1, 2008Date of Patent: March 4, 2014Assignee: Imperial Innovations LimitedInventors: Parashkev Nachev, Matthieu Pierre Alcime Robert
