Abstract
The invention relates to an arrangement with a spectacle lens having a changeable optical effect and with an effect-setting apparatus for setting the optical effect of the spectacle lens on the basis of intended-setting data. A memory apparatus stores first intended-setting data for setting a first predetermined optical intended effect, which was established from a first refraction measurement on an eye of a spectacles wearer for whom the spectacle lens is destined, and for storing second intended-setting data for setting a second predetermined optical intended effect, which was established from a second refraction measurement on the eye, and also a supply apparatus for supplying the first intended-setting data or the second intended-setting data to the effect-setting apparatus.
