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: The invention relates to a method of manufacturing an optical system (OS), the optical system (OS) being identified by a function (OF), the optical system (OS) comprising a first part (F1) defined by a first equation (EF1) and a second part (F2) defined by a second equation (EF2), the method comprising: - a calculation step (CAL), in which the second equation EF2 is calculated from the function OF, and the first equation EF1; - a first manufacturing step (M1), in which a semi-finished optical system (SFOS) comprising the first part (F1) is manufactured so as to obtain a manufactured semi-finished optical system (MSFOS); and - a second manufacturing step (M2), in which the manufactured semi-finished optical system (MSFOS) is manufactured so as to be further provided with a second part (F2) defined by the second equation (EF2) and to obtain the optical system (OS).

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.
