Patent ID: 8789946

Claim:
A method for producing a spectacle lens with prismatic power for a spectacle wearer, comprising: obtaining individual user data of the spectacle wearer, wherein the individual user data comprises prismatic prescription data; designing the spectacle lens with prismatic power taking into account the individual user data; and determining centration data for the spectacle lens with prismatic power depending on the prismatic prescription data, wherein the individual user data comprises a corneal vertex distance e and/or an ocular center of rotation distance b′ and/or an edge thickness d R of the spectacle lens and/or a center thickness and/or a lens forward inclination or frame forward inclination and/or a face form angle and/or a spectacle lens diameter or lens shape diameter and/or at least a refractive power and/or a refractive index of the spectacle lens and/or a base curve and/or an astigmatic power and/or an addition, and the centration data and in particular the centration shift s Z is determined depending on the corneal vertex distance e and/or the ocular center of rotation distance b′ and/or the minimum lens thickness d min of the spectacle lens and/or the center thickness and/or the lens forward inclination or frame forward inclination and/or the face form angle and/or the spectacle lens diameter or lens shape diameter and/or the at least one refractive power and/or the refractive index of the spectacle lens and/or the base curve and/or the astigmatic power and/or the addition, and wherein the centration shift s Z in the unit mm is determined depending on the corneal vertex distance e in the unit mm and the prismatic power p in the unit cm/m according to s z = ( e + 15 ) ⁢ p 10 in the direction toward the base of the prism.
