    Abstract: A method of ordering an ophthalmic lens comprises the following steps: —obtaining data representative of a desired correction for a wearer's eye; —determining (S6, S8), using an electronic device, a lens power to be measured on a lensmeter based on the obtained data and on at least one parameter defining an expected position of the lens with respect to the wearer's eye, wherein the lens power corresponds to the power measured on the lensmeter for a lens adapted to provide the desired correction to the wearer's eye when placed at the expected position with respect to the wearer's eye; —ordering (S10) the ophthalmic lens specifying the determined power. A corresponding system is also provided.

    Abstract: A method includes acquiring prescription data including an addition value. The method includes generating virtual surface data of a progressive addition lens for a further operation of surfacing of a lens blank, the operation of surfacing being configured to transform the lens blank into a surfaced lens satisfying the prescription data. The generating virtual surface data includes selecting a virtual base surface in a virtual base surface database, the selection being independent of the prescribed addition value, processing the selected virtual base surface according to the prescribed addition value to obtain a modified virtual base surface, selecting a virtual adjusting surface in a virtual adjusting surface database at least on the basis of a value of a parameter relative to the modified virtual base surface, and combining the modified virtual base surface and the selected virtual adjusting surface to form a virtual progressive adjusted surface.
