Claim 5:
6. A method for producing at least one spectacle lens for the at least one eye of the user, wherein the producing of the spectacle lens comprises processing a lens blank, wherein the processing of the lens blank is based on instructions configured to compensate at least one ocular aberration of the at least one eye of the user, and wherein the ocular aberration of the at least one eye is determined by a method for determining an ocular aberration of at least one eye of a user, the method comprising the following steps:
a) measuring at least one optical wavefront comprised by at least one light beam, wherein an ocular aberration of the at least one eye of the user is determined from the at least one optical wavefront; and
b) generating multiple diffraction orders in the at least one light beam in two meridians in a manner that the multiple diffraction orders are spatially separated in the at least one eye of the user and on the wavefront sensing unit,
wherein the multiple diffraction orders include at least a zeroth diffraction order and at least two first diffraction orders in each meridian, and wherein at least nine light spots are generated across the wavefront sensing unit in the two meridians.
