摘要： A method and apparatus for automatically measuring the circumference 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 present invention includes generating a point inside an interior of the first region. A set of radial vectors are then generated, which emanate from the point in the interior of the first region. A path is then selected which intersects the set of radial vectors. The path is selected by identifying a distinguishable ultrasonic measurement along the respective radial vectors. A length of the selected path is then measured to generate the circumference of the first region.

摘要： A bifocal spectacle lens and a method for creating a numerical representation of a bifocal spectacle lens are disclosed. The bifocal spectacle lens includes a distance portion, a near portion, and a transition section situated between the distance portion and the near portion. The distance portion is optimized in view of an optical power for distance vision and the near portion is optimized in view of an optical power for near vision. The transition section is determined such that the transition section creates a continuous transition between the distance portion and the near portion. The distance portion and the near portion are optimized independently of one another and put together with the transition section to form the numerical representation of the bifocal spectacle lens.

摘要： 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 characterized 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.

摘要： A progressive addition lens contains a plurality of microlenses for providing simultaneous myopic defocus. The microlenses are superimposed on a power variation surface of the lens, which includes a designated distance portion in the upper section of the lens adapted for distance vision and a fitting cross; a designated near portion located in the lower section of the lens, the near portion including a near reference point having a near dioptric power adapted for near vision; and a designated intermediate corridor extending between the designated distance portion and near portions. Microlenses are excluded from all areas of the surface located below a notional line extending from nasal to temporal limits of the lens at a vertical coordinate above the near reference point where the vertical coordinate lies at a distance above the near reference point with the distance being in a range between 1.5 mm and 3 mm.

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, 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.

摘要： An ophthalmic lens element (100) for correcting myopia in a wearer's eye is disclosed. The lens element (100) includes a central zone (102) and a peripheral zone (104). The central zone (102) provides a first optical correction for substantially correcting myopia associated with the foveal region of the wearer's eye. The peripheral zone (104) surrounds the central zone (102) and provides a second optical correction for substantially correcting myopia or hyperopia associated with a peripheral region of the retina of the wearer's eye. A system and method for dispensing or designing an ophthalmic lens element for correcting myopia in a wearer's eye is also disclosed.
