According to the invention, a method for producing a spectacle lens or a pair of spectacle lenses is proposed which comprises a calculation and optimization step for at least one of the surfaces of the spectacle lens taking into account an anisometropia D of the eyes of a spectacles wearer, said calculation and optimization step involving a target function F being minimized: minF=&Sgr;igPi((PR(i)−PL(i))−Psoll(i))2, where: PR(i) is a prismatic effect at the i-th evaluation point of the spectacle lens; PL(i) is a prismatic reference effect at the i-th evaluation point of the spectacle lens; Psoll(i) is a desired value of the difference &Dgr;P in prismatic effect and prismatic reference effect at the i-th evaluation point of the spectacle lens; and gPi is a weighting of the prismatic effect at the i-th evaluation point of the spectacle lens; and where the prismatic reference effect PL(i) is the prismatic effect at a visual point of a second spectacle lens corresponding to the i-th evaluation point, and the spectacle lens and the second spectacle lens form a pair of spectacle lenses for joint use in spectacles for correcting the anisometropia of the spectacles wearer. The invention further relates to a computer program product, a storage medium, a device for carrying out the method, and a pair of spectacle lenses and the use thereof for correcting an anisometropia of a spectacles wearer.
