    Abstract: The lens has a power addition prescription and a complex surface presented with a fitting cross. A far vision zone has a control point, and a near vision zone has a control point and an intermediate vision zone. A principal meridian of progression passes via the three zones. A reduced root mean square deviation is normalized to the addition prescription of less than a specific decimal value of microns per dioptre over a zone that includes the far vision control point. A progression length is defined as an angle of lowered viewing from the fitting cross down to the point on the meridian. An independent claim is also included for a method of correcting the vision of a presbyopic subject.

    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: The invention concerns an apparatus and a method for transmission measurement of the geometric structure of an optical component (2), comprising steps which consist in: illuminating the optical component with a first incident light (8, 10) whereof the wave front is known; measuring by deflectometry 16, 18) the wave front of said first light after transmission by said optical component; illuminating the optical component with a second incident light (12, 14) whereof the wave front is known; measuring by deflectometry (16, 18) the wave front of said second light after transmission by said optical component; and calculating the geometric structure of said optical component from the measured wave fronts during the measuring steps. The measurement of the light transmitted in two separate optical configurations enables to calculate by optimisation of the two surfaces of the component, without prior knowledge of one of the surfaces. The first and second lights can be different and illuminate a common surface of the component, identical lights can also be used and each surface of the component can be illuminated successively.
