    Abstract: 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.

    Abstract: The invention provides multi-focal segmented lenses with boundaries that include at least one blended portion and at least one sharp portion. The lenses may possess, for example, the aesthetic advantage of blended multi-segment or progressive lenses while largely retaining the functional advantage of multi-segment lenses with sharp segment boundaries.

    Abstract: 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.

    Abstract: An array of progressive ophthalmic lens elements is disclosed. The progressive ophthalmic elements contained in the array having substantially the same addition power and substantially the same optical prescription for distance vision. Each of the progressive ophthalmic lens elements has a progressive lens design characterised by a set of parameters defining a distance zone providing a refracting power for distance vision, a near zone providing a refracting power for near vision and a corridor having a refracting power varying from that of the distance zone to that of the near zone. The progressive ophthalmic lens elements provide, for a range of values or categories of at least two lifestyle and/or biometric parameters of lens wearers, different progressive lens designs in which at least two of the lens design parameters each have a respective value or characteristic attributable to, or associated with, a particular value or category of a respective one of the lifestyle and/or biometric parameters.

    Abstract: A method of designing and/or selecting a progressive addition lens design for a wearer is disclosed. In an embodiment, the method includes displaying a graphical representation of an initial progressive addition lens design including design parameters having design values. A user interface is provided including, for each of one or more of the design parameters, a control that is adjustable over a range of levels, each level in the range being associated with a corresponding value of the respective design parameter. A control is adjusted to select a level and the selection is processed so as to substantially simultaneously update the displayed graphical representation in accordance with the selected level to provide a modified progressive lens design. A system for designing and/or selecting a progressive addition lens design for a wearer is also disclosed.

    Abstract: A method and apparatus for automated measuring of a diameter of a first region enclosed in a second region internal to a living organism, wherein the first and second regions consist of different cellular matter. One embodiment of the invention includes generating a plurality of trial diameters, wherein each trial diameter includes an inner and outer region and has a different length. An ultrasonic measurement is taken of the inner region and the outer region for each trial diameter. The difference is determined for the ultrasonic measurements corresponding to the inner and outer regions of each trial diameter. The trial diameter which most closely corresponds to the diameter of the first region is then selected, wherein the difference of the ultrasonic measurements corresponding to the inner and outer regions is greatest for the trial diameter which most closely corresponds to the diameter of the first region.
