    摘要： Provided is technology that makes it possible to measure visual behavior with respect to objects that are at different distances in the depth direction, while reducing burden on a subject. A method for measuring visual behavior of a subject to design an eyeglass lens includes: a step (a) of ascertaining a head rotation amount that is generated by the subject in a sagittal plane of the subject when gazing at each of a plurality of gaze points that are set at predetermined distances different from each other in a forward depth direction; and a step (b) of determining an eyeball rotation amount that is generated by the subject when gazing at each of the plurality of gaze points, based on the head rotation amount.

    摘要： Generating an aspheric contact lens design for facilitating myopia control of a cornea of a patient includes operations of: obtain measurement for degree refractive error of the eye in diopters; obtain measurement of one or more biomechanical properties of the cornea; define a diameter of a central zone of the contact lens based on pupil size; select a base curve profile and width for the central zone based on the refractive error and the one or more biomechanical properties; define a width of a reverse zone adjacent to and encircling the central zone, the width being greater than 0.5 mm; select a reverse curve profile for the reverse zone compatible with the base curve profile; modify the base curve profile adjacent to the reverse zone by applying a selected base eccentricity curve profile for enhancing the tension force strength of the reverse zone; define a width of a relief zone of the contact lens adjacent to and encircling the reverse zone; select a relief curve profile for the relief zone; define a width of an alignment zone of the contact lens adjacent to and encircling the relief zone; select an alignment curve profile for the alignment zone; and define a width of a peripheral zone of the contact lens adjacent to and encircling the alignment zone; select a peripheral curve profile for the peripheral zone; wherein the compression force strength and the tension force strength of the contact lens cooperate to reshape corneal curvature in a mid-peripheral region to address the myopia control when the contact lens is applied to the eye.

    摘要： A method is provided for producing an optical member. The method includes removing a portion of a low refractive index layer, which is the outermost layer of a multilayer structure in which the low refractive index layer and a high refractive index layer are layered on each other. Non-heating processing is performed on an antireflection film that is formed to cover an optical surface of an optical base member and has the multilayer structure, through irradiation with an ultrashort pulse laser beam, so as to expose the high refractive index layer.

    摘要： System for order-receipt processing of an eyeglass lens, including: a receiver configured to receive order data of eyeglass lens, to store a catalog of eyeglass lens classes, which each are defined by a fixed number of predetermined and freely selectable order parameters and differ from each other in the number of freely selectable order parameters, and to classify the order data on the basis of the catalog of eyeglass lens classes, a processor configured to process the order data, to store only the highest eyeglass lens classes of the catalog of eyeglass lens classes, to select one of the highest eyeglass lens classes, to match the order data to the selected highest eyeglass lens class, to generate a respective digital reproduction of the eyeglass lens based on a calculation model and the adapted order data, and a communication device connecting the receiver and the processor.

    摘要： An ophthalmic lens includes an optic having a first surface and a second surface disposed about an optical axis. At least one of the first surface and the second surface includes a surface profile having a base curvature and a plurality of zones. The base curvature corresponds to a base optical power. The plurality of zones is adapted to produce a plurality of curves corresponding to light energy distribution along the optical axis. The surface profile includes a plurality of adjustments providing an extended depth-of-focus, the plurality of adjustments being adapted to extend each one of the plurality of curves towards another of the plurality of curves. The plurality of adjustments may include at least one spherical aberration. The plurality of adjustments may include at least one longitudinal chromatic aberration. The plurality of adjustments may include at least one phase shift change.

    摘要： Safety glasses for a human user, with at least one lens which has an upper rim assignable to the user's forehead and a lower rim assignable to a user's cheek, with at least one nosepiece arranged at the at least one lens and with at least one protective lip to be supported on the user's face. The at least one protective lip only extends at the lower rim of the at least lens from the at least one nosepiece towards at least one of the outer lateral rims of the lens and, in extension of the lens, downwards from the lower rim of the lens to be supported on the user's cheek.
