    Abstract: The invention concerns a set of progressive multifocal ophthalmic lenses, ea ch having a first progressive multifocal surface and a second surface preferabl y spherical. It proposes to define the set of lenses with regard to the optical characteristics of the lenses, and particularly wearer power and oblique astigmatism, in wor n conditions. For this purpose, the invention defines an ergorama associating with each sight direction in worn conditions a target object point, and a given power. This ergorama supplies a power target for a definition by optimisation of the lenses, and is used in a radii plotting programme for calculating the optical characteristics during optimisation. The set of lenses has substantially identical optical performances for a given addition, whatever the power of the far vision reference point.

    Abstract: The invention relates to a method of processing an unfinished optical lens member for manufacture of an optical lens from the unfinished optical lens member, the unfinished optical lens member being provided with a finished surface having a geometrical centre reference point, the optical lens having a first and a second surface, said first surface being comprised in the finished surface of the unfinished optical lens member, the method comprising: providing contour data defining the contour of the first surface of the optical lens in a finished cut state, the maximum distance between two points of the contour being defined by a distance C

    Abstract: La invención se refiere a un procedimiento de determinación por optimización de una lente oftálmica para un portador al que se le ha descrito un astigmatismo que comprende las etapas de:- elección de una lente de partida y definición de una lente corriente igual a la lente de partida;- elección de una lente esférica diana;- determinación de la lente por optimización de la lente corriente, para minimizar en una pluralidad de direcciones de la mirada y en una referencia unida al ojo;- - la diferencia entre la potencia de la lente corriente y la potencia de la lente diana;- - la diferencia entre el astigmatismo residual y el astigmatismo de la lente diana;definiéndose el astigmatismo residual como el desvío entre el astigmatismo prescrito y el astigmatismo generado por la lente corriente al vez en amplitud y en eje en la referencia ligada al ojo y para cada dirección de la mirada. La potencia, el astigmatismo y el astigmatismo residual se calculan por el trazado de los rayos.La invención permite evitar las aberraciones inducidas para un portador astigmático por la adición de una superficie tórica que presenta el astigmatismo prescrito. Garantiza que el astigmatismo efectivamente percibido por el portador es el astigmatismo prescrito.

    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.
