Method for calculation and optimization of a spectacle lens pair, taking into account binocular properties

The invention relates to the optimization and production of at least a first spectacle lens for a pair of spectacle lenses for use together with a second lens of the pair of spectacle lenses in a pair of spectacles for a specific situation of use, wherein a process of the invention a binocular calculation or optimization step at least one surface the first spectacle lens includes such a manner that a target function is minimized, which as the sum of at least a first function monocular and a binocular function F is defined, wherein the first function monocular by the values of at least a first monocular optical property Mon each consisting of a binocular valuator the first spectacle lens and a corresponding in the specific situation of this binocular valuator the second spectacle lens of the values of a second monocular optical Mon the first spectacle lens and at the evaluation point binocular the second spectacle lens depends.
