摘要： A computer-implemented method for providing a lens shape for an ophthalmic lens is disclosed. Further, there is provided a method for angular smoothing of a surface determined by carrier lines radially outwards of a prescription zone bordered by a first boundary line. In addition, there is provided an ophthalmic lens, in particular, a spectacle lens. Moreover, a method for minimizing the difference in thickness between two ophthalmic lenses for the same spectacles is provided. A computer program product and a machine-readable storage medium are provided as well.

摘要： A protective shield can be mounted in front of the face of a wearer of a protective helmet. In an as worn orientation, the protective shield extends across the eyes and typically also across the nose of the wearer. The protective shield has at least one arcuate lens portion which, in the as worn orientation, curves across an eye of the wearer. The arcuate lens portion has a horizontal curvature extending in a horizontal direction and a vertical curvature extending in a vertical direction, wherein the vertical curvature is a horizontally varying vertical curvature (κ).

摘要： A manufacturing method for manufacturing a spectacle lens is disclosed. The method includes: obtaining prescription data descriptive of an ophthalmic prescription of a user in the plus prescription range; obtaining frame data descriptive of a perimeter of a spectacle frame in which the lens is to be mounted; providing a lens blank having a convex front surface and a back surface; determining a final cutting surface to be machined on the back surface of the lens blank in a final cutting phase; and determining an intermediate cutting surface to be machined on the back surface of the lens blank in an initial cutting phase. Further, it is provided that the intermediate cutting surface is different from the final cutting surface; and the final cutting surface comprises a prescription zone in which the final cutting surface together with the front surface fulfills the ophthalmic prescription of the user.

摘要： An adjustable spectacle lens has a first lens element and a second lens element arranged one behind the other along an optical axis of the lens. The first and second lens element are configured to vary their combined optical properties when moved relative to each other in a direction transverse to the optical axis. The adjustable lens element is an adjustable progressive lens element. The first and second lens element are configured to vary at least one of a size and a power of the near, the distance, and the intermediate portion relative to each other, when the first lens element and the second lens element are moved relative to each other in the direction transverse to the optical axis. The first and second lens elements can be configured to conjointly provide a near, a distance and an intermediate portion that can be changed depending on the visual task.

摘要： A method of determining an ophthalmic prescription (Rx) for a patient's eye, includes obtaining a wavefront measurement of the patient's eye; determining a first Rx for the patient's eye from the wavefront measurement, the first Rx corresponding to a maximum value of a merit function calculated from the wavefront measurement of the patient's eye for a first size of the pupil of the patient's eye; determining one or more additional Rx's of the patient's eye for one or more additional pupil sizes different from the first pupil size, wherein each additional Rx is determined for a corresponding size by calculating a value of the merit function for the previously-calculated Rx at the corresponding size and searching for an Rx at the corresponding size that provides a larger value of the merit function than the previously-calculated Rx at the corresponding size; determining a final Rx based on the first Rx and the additional Rx's; and outputting the final Rx.

摘要： A progressive spectacle lens, a method for its production, and a related computer program are disclosed. The progressive spectacle lens has a progressive surface including a central viewing zone, a lower viewing zone, two peripheral vision zones extending bilaterally from a vertical meridian of the progressive surface, and an upper viewing zone. The central viewing zone has a surface power providing a first refracting power for distance vision and the lower viewing zone has a greater surface power than the central viewing zone providing a second refracting power corresponding to near vision and being connected to the central viewing zone by a first progressing power region. The progressive spectacle lens generates a retarding or arresting effect on myopia progression, especially in myopic juveniles.

摘要： A method, a system and a computer program for determining an eyeglass prescription for an eye are disclosed. Initially, information about a measurement indicative of the refractive properties of the eye is received. Subsequently, a mathematical representation of wavefront aberrations of the eye is determined from the measurement. The mathematical representation includes a multitude of polynomials, each polynomial having an azimuthal order and a radial order. Further, the mathematical representation includes at least a first polynomial group having a common radial order, wherein the common radial order is higher than two. The eyeglass prescription is determined based on a merit function, wherein each polynomial of the first polynomial group that is used in the merit function has an azimuthal order of −2, 0, or 2, respectively.
