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: A progressive multifocal ophthalmic lens is provided having an aspherical surface with a mean sphere and a cylinder at every point. The aspherical surface has a distance vision portion, with a control point for distance vision, a near vision portion with a control point for near vision, and an intermediate vision portion between the near vision portion and the distance vision portion. A power addition value A is defined as a variation in mean sphere between the control point for distance vision and the control point for near vision portion. A base B is defined as a value of mean sphere at the control point for distance vision. A width of the near vision portion varies not only as a function of the power addition value A, but also as a function of the value B of the base. The invention thereby ensures the presence of a substantially constant object field for all values of the power addition and of the base.

Abstract: A progressive multifocal ophthalmic lens is provided having an aspherical surface comprising a distance vision portion, a near vision portion and an intermediate vision portion, in which the maximum mean sphere gradient value is situated in the intermediate vision portion of the principal meridian of progression of the lens, and the cylinder gradient over the whole aspherical surface of the lens is less than the product obtained by multiplying the power addition value at each point by a constant value coefficient.
