The present invention relates in one aspect to an improved determination of objective refraction data for an eye of a spectacle wearer, wherein based on measured data for the eye of the spectacle wearer, which determine at least one first set of Zernike coefficients of a wave front aberration for a long accommodation and a second set of Zernike coefficients of a wave front aberration for a short accommodation of the eye, objective refraction data for sphere (I), cylinder (II) and axis position (III) of the eye for close viewing is determined such that the objective refraction data satisfies equations (IV), (V) and (VI) for a corrected power vector (VII) for near viewing, wherein said corrected power vector (VII) corresponds, based on a difference (VIII) between a first power vector (IX) and a second power vector (X), to the value (XI), when DeltaMu > A 1 N ; and to the value (XII), when DeltaMu <= A 1 N , wherein (XIII) is the spherical equivalent of a predetermined object distanced for close viewing. |
