  • Patent number: 10371964
    Abstract: A contact lens product includes a multifocal contact lens and a buffer solution. The multifocal contact lens is immersed in the buffer solution. The multifocal contact lens includes a central region and at least one annular region. The annular region concentrically surrounds the central region, and a diopter of the annular region is different from a diopter of the central region. The multifocal contact lens is made of silicone hydrogel or hydrogel. The annular region closest to a periphery of the multifocal contact lens is a first annular region.

  • Patent number: 9733492
    Abstract: A set of eyeglass lens semifinished products is provided and is composed of at least three series of eyeglass lens semifinished products having spherical or rotationally symmetric aspherical front surfaces. The series of eyeglass lens semifinished products differ in pairs in the base material of the series. Each of the series includes at least three types of eyeglass lens semifinished products which differ in pairs and the front surface shapes. The front surface shapes of the at least three types are identical on a central partial surface within the actual surface refractive power range of the front surface of the series in relation to a standard index of refraction of 1.53 between 3.2 D and 6.7 D.

  • Patent number: 9482884
    Abstract: The present disclosure provides systems and methods for determining an ophthalmic lens. In one implementation, three-dimensional coordinates of a center of rotation of the wearer's eye measured on the wearer in binocular vision are received. At least one direction of gaze measured in a natural posture and a determined position of the ophthalmic lens are received. Characteristics of the ophthalmic lens are calculated by using the coordinates measured for the center of rotation of the eye, the determined position of the lens, and the at least one direction of gaze measured in a natural posture. The characteristics of the ophthalmic lens are calculated by positioning a starting ophthalmic lens in the determined position and modifying the starting ophthalmic lens by wavefront analysis and/or optimizing using ray tracing dependent on the coordinates measured for the center of rotation of the eye and the determined position of the lens.

  • Patent number: 9039173
    Abstract: The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger, bolder, and enhanced color while giving the wearer's eyes a very natural appearance. A colored contact lens of the invention comprising a first print of a first color and a second print of a second color, wherein the first print consisting of an annular ring of gradient dot matrix, wherein the second print comprises a limbal ring and an outer starburst pattern, wherein the limbal ring surrounds the outer starburst pattern, wherein the annular ring and the limbal ring have a substantially identical outer diameter and the annular ring has a larger inside diameter than the limbal ring, the first color and the second color are different or the same, wherein the first print and the second print are concentric with the center of contact lens.

  • Publication number: 20140118681
    Abstract: A process for making a temporary photochromic patch for an ophthalmic lens. A photochromic dye is dissolved in either a siloxane base or curing agent. The base and curing agent are combined to initiate a polymerization reaction that will result in a polydimethylsiloxane (PDMS) polymer matrix having sufficiently low molecular weight to accommodate the photochromic dye's mobility. The polymerization reaction is completed in a form to create a viscoelastic patch. The resulting patch can be trimmed and temporarily applied to an ophthalmic lens without needing adhesive.

  • Patent number: 8708495
    Abstract: A method and apparatus for correcting vision in macular degeneration patients. Following a diagnostic procedure which has been successfully tested to determine the factors needed to correct the vision of a patient with macular degeneration, the present invention describes a prototype correcting procedure and device using a computer program and display device. Through manipulation of a grid and quantitative analysis of the manipulations, the extent and correction factors needed to correct the vision of a macular degeneration patient are discussed.
