摘要： A method and system provide a multifocal ophthalmic device. The ophthalmic lens has an anterior surface, a posterior surface and at least one diffractive structure including a plurality of echelettes. The echelettes have at least one step height of at least one wavelength and not more than two wavelengths in optical path length. The diffractive structure(s) reside on at least one of the anterior surface and the posterior surface. The diffractive structure(s) provide a plurality of focal lengths for the ophthalmic lens.

摘要： A method and system for generating a three-dimensional model of a contact lens with a front and a back surface, in which the entire back surface consists of an array of independent data points shaped to conform to three-dimensional data provided by an ocular topographer. The sampling density is sufficiently high to characterize anomalies or injuries anywhere in the eye to optimize comfort and fit. The methods and systems also include modeling a scleral lens which rests either solely on the sclera, or straddles the limbus extending partially into the cornea is described. The resting surface conforms to the topology of the underlying ocular surface with topology guiding the design. Additional methods and systems model scleral lens optics without the use of trial lenses. The lens models can be used to machine or 3D print a lens that fits the patient. Such lenses benefit patients that suffer from dry eyes or whose eyes are not normally dry, but feel dry after wearing conventional contact lenses.

摘要： A technology concerns a spectacle lens to suppress unnecessary convergence. In the spectacle lens, when an inner horizontal direction of the spectacle lens is a direction toward the nose of a user who wears the spectacle lens, and an outer horizontal direction of the spectacle lens is a direction toward an ear of the user, a shape of a base in prism is formed in a portion in which power continuously changes and through which a main line of sight, influenced by convergence of the user of the spectacle lens, passes such that at least a part of a base out prism, which may be generated in the portion, is cancelled.

摘要： A method, implemented by a computer, for determining a lens design of an optical lens adapted to a wearer, the method including: providing a wearer parameter; a lens design determining, during which the lens design of the optical lens adapted to the wearer is determined based at least on the wearer parameters. The wearer parameters include at least optical distortion sensitivity data representative of sensitivity of the wearer to optical distortions.

摘要： An eye-mountable device (EMD) includes a lens enclosure, liquid crystal material, first and second electrodes, a substrate, and a controller. The lens enclosure includes a first encapsulation layer and a second encapsulation layer sealed to the first encapsulation layer. The liquid crystal material is disposed across a central region of the lens enclosure. The first electrode is disposed within the lens enclosure between the first encapsulation layer and the liquid crystal material. The second electrode is disposed within the lens enclosure between the second encapsulation layer and the liquid crystal material. The substrate is disposed within the lens enclosure between the first and second encapsulation layers. The controller is disposed on the substrate and electrically coupled to the first and second electrodes to apply a voltage across the liquid crystal material.

摘要： A system for correcting human vision includes a mobile device in wireless communication with a vision correction device. The vision correction device includes lenses that are positioned to correct a user's vision. The mobile device generates adjustment information in response to receiving input information from a user. The mobile device wirelessly transmits the adjustment information to the vision correction device. The vision correction device adjusts a focal length of the lenses in response to receiving the adjustment information. The mobile device can be a smartphone or tablet computer. The input information from the user can be based on one or more of a user's finger interaction with a touchscreen and an image captured by the mobile device.

摘要： A process for applying a film structure onto a lens blank is improved by implementing a wedge piece when the film structure is pressed against the lens blank using a resilient cushion. The wedge piece forces the film structure to conform more tightly to the lens blank within a depression track existing on said lens blank. Then, the lens blank assembled with the film structure has a final optically useful area which is increased.

摘要： This method, which allows acquisition and computation of geometrical data of at least one pattern associated with an ophthalmic object (6) for manufacturing ophthalmic lenses similar to the object or complementary thereto, is of the type in which a device (12) for acquiring and computing geometrical data is used, which comprises: a transparent support (13) adapted for bearing an ophthalmic object; on one side of the support, means (17) for illuminating this support; on the other side of the support, a video camera (25) adapted for producing a video signal representative of at least one pattern associated with the ophthalmic object laid on the support; and signal processing and analysis means (27) receiving at the input the video signal produced by the camera, and adapted for computing and providing the geometrical data. The method is characterized in that: (a) a verification pattern independent of said geometrical data is traced on the ophthalmic object (6), this verification pattern being asymmetrical relatively to each of two axes perpendicular to each other; (b) the ophthalmic object is positioned on the transparent support (13) of the acquisition and display device (12); and (c) by means of said device (12), said verification pattern is optically captured and analyzed.
