    Abstract: A method for determining a progressive ophthalmic lens comprising a near and a far vision area, a main meridian separating the lens into a nasal and a temporal area, the method comprising: determining a first and a second surface of the lens; determining the second surface to provide, in combination with the first surface, the vision correcting properties; determining a spherical area on the first surface of the lens having a constant sphere value and including a far vision diopter measurement position, wherein the far and a near vision diopter measurement position have substantially the same mean sphere value; and determining the first surface to reduce the lens distortion by defining a toric area extending outside the spherical area on the first surface in at least one of the nasal and the temporal area, wherein characteristics of the toric area are related to the lens astigmatism.
