Abstract: In a progressive multifocal ophthalmic lens providing excellent performance in the far vision region, good width of the near vision region and gentle progression in the intermediate vision region therebetween, the far vision region comprises an angular sector defined by two half-lines that intersect at the geometrical center of the lens forming an upwardly-directed angular segment with an included angle of preferably more than 145.degree. in which all points have a cylinder less than A/2 diopters, and constraints are applied governing the gentleness of progression in the intermediate vision region and the relative width of the near vision region.

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: The lens has an aspherical surface (S) presenting at any point a mean sphere and cylinder, having a distance vision zone (VL), a near vision zone (VP), an intermediate vision zone (VI) and a main meridian of progression (MM') passing through all three zones. The relationship between a maximum cylinder within a circle of 20 mm radius centered on the geometrical center of the lens and the distance from the center to a point inside the circle or maximum cylinder is less than or equal to half the maximum inclination of the mean sphere on the main meridian of progression.

Abstract: 18 A multifocal ophthalmic lens comprising a far vision region, a near vision region and an intermediate vision region is provided having a high near vision region and a wide vision field in the near vision region, the intermediate vision region and in the far vision region. Progression is gentle although the distance between a mounting center on the lens and the point where power addition is 85% higher than power addition at a far vision control point is less than 16 mm, while simultaneously maximum cylinder inside a 20 mm radius circle centered on a geometrical center of the lens is kept at a low value.

Abstract: The invention relates to a method of calculating an optical system (OS), the optical system (OS) being identified by a function (OF), the optical system (OS) comprising a first part (Fl) defined by a first equation (EFl) and a second part (F2) defined by a second equation (EF2), the method comprising: -a generating step (GEN), in which a virtual optical system (VOS) is used to generate a virtual function (VOF); - a modification step (MOD), in which the virtual function (VOF) is modified so as obtain the function (OF); - a calculation step (CAL), in which the second equation (EF2) is calculated from the function (OF), and the first equation (EFl). The invention relates also to a method of manufacturing an optical system (OS).
