    Abstract: Progressive multifocal ophthalmic lens having a power addition prescription and presenting a complex surface having a fitting cross and a principal meridian of progression. The lens has, when being worn, a normalized reduced root mean square deviation of less than 0.025 microns per dioptre over a zone that includes the far vision control point and covering a sector whose apex lies 4~ below the fitting cross with an angular aperture of between 150~ and 160~; and a progression length of 25~ or less, the progression length being defined as the angle of lowered of the view direction from the fitting cross down to the point on the meridian for which the wearer's optical power reaches 85% of the addition prescription. The lens is suitable for increased far vision with good accessibility to near vision.

    Abstract: A method for measuring the geometrical structure of an optical component ( 2 ) in transmission, comprises illuminating the optical component by means of a first incident beam ( 8, 10 ), the wavefront of which is known. After the first beam is transmitted by the optical component, its wavefront is measured by deflectometry ( 16, 18 ). The optical component is then illuminated by a second incident beam ( 12, 14 ), the wavefront of which is known. After the second beam is transmitted by the optical component, its wavefront is measured by deflectometry ( 16, 18 ). The geometrical structure of the optical component is then calculated from the measured wavefronts. Measuring light transmitted in two distinct optical configurations allows a calculation by optimizing the two surfaces of the component, without prior knowledge of one of the surfaces. The first and second beams may be different and may illuminate the same surface of the component; thus it is possible to use identical beams and to illuminate each surface of the component in succession.

    Abstract: Une lentille ophtalmique multifocale progressive ayant une prescription d'addition de puissance (A) et présente une surface complexe ayant une croix de montage (CM) et une méridienne principale de progression. La lentille présente, dans les conditions du porté, un écart quadratique moyen (RMS) réduit normalisé inférieur à 0,025 micromètre par dioptrie sur une zone incluant le point de contrôle en vision de loin (VL) et couvrant un secteur dont le sommet est situé 4 degree sous la croix de montage avec une ouverture angulaire comprise entre 150 degree et 160 ; et une longueur de progression (LP) inférieure ou égale à 25 degree , la longueur de progression étant définie comme l'angle d'abaissement du regard depuis la croix de montage jusqu'au point de la méridienne pour lequel la puissance optique porteur atteint 85% de la prescription d'addition (A)La lentille est adaptée à une vision de loin élargie avec une bonne accessibilité à la vision de près.

    Abstract: The lens has an aspherical surface (S) with a distant vision zone (VL), a close vision zone (VP) and an intermediate vision zone (VI), with a main progression meridian (MM') passing through the three zones. The three vision zones (VL, VP, VI) are separated by isocylindrical lines, and the distant vision zone has a sector angle of at least 145 degrees. A line bisecting the angle forms an angle of less than 5 degrees, and pref under 2 degrees with a vertical.

    Abstract: An ophthalmic lens intended to be worn in front of an eye of a wearer having a first optical function based on a prescription of the wearer for correcting an abnormal refraction of said eye of the wearer and comprising at least one activable optical element, wherein in a first state the at least one activable optical element contributes with the rest of the lens to focus the image of an object at distance on the retina, and in a second state the at least one activable optical element has a second optical function of not focusing an image on the retina of the eye of the wearer so as to slow down the progression of the abnormal refraction of the eye
