REFRACTIVE OPTICAL COMPONENT AND SPECTACLE LENS PRODUCED THEREFROM, METHOD FOR PRODUCING A REFRACTIVE OPTICAL COMPONENT, COMPUTER PROGRAM PRODUCT, CONSTRUCTION DATA OF A SPECTACLE LENS STORED ON A DATA MEDIUM, DEVICE FOR ADDITIVE MANUFACTURING OF A MAIN BODY, AND SPECTACLE LENS

A refractive optical component (1) has a main body (10) with a plurality m of optical layers (5i) extending between a front side (2) and a back side (3), each layer having a thickness (di) in the direction parallel to the principal axis, wherein each of the layers (5i) extends over a region common to all layers (5i) in directions perpendicular to the principal axis, said common region being greater than the maximum thickness (dimax) of the respective layer (5i) by at least a factor of 10, wherein the thickness (di) of the layers (5i) varies over the extent thereof transversely to the principal axis, and wherein the main body (10) has a refractive index curve (n = n(x, y, z)), modulated at least in the direction parallel to the principal axis, with a plurality of maxima and minima, a distance between adjacent maxima and minima ranging between 0.5 (mu)m and 100 (mu)m and a refractive index difference Delta n between adjacent maxima and minima ranging between 10-4 and 0.3, wherein a number of maxima in the refra
