Abstract: 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.

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: 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: A method and apparatus for determining resistance and pulsatility indices of a flow of material, such as the flow of blood in the human body. This may be implemented, for example, in a color flow module in an ultrasonic imaging system for display of the pulsatility or resistance index in two dimensions and in different colors to allow discrimination between veins and arteries and detection of pathologic elevation of vascular resistance in a clinical survey mode of the system. The resistance index is determined from the ratio of a unipolar variation estimate of a velocity of the flow material divided by a peak velocity. The variation estimate may be one of the following: a difference between a peak velocity of the flow of material and a second minimum (if unipolar) or negative (if bipolar) velocity of the flow of material, a standard deviation .rho. of the velocity of the flow of material, a square root of a value at a first peak of an autocorrelator of the velocity of the flow of material, and a square root of a value at a second peak of the autocorrelator of the velocity of the flow of material.
