Abstract

An ophthalmic lens has a changeable corrective effect, which automatically changes over a predetermined period of time. Further, the ophthalmic lens provides a gradually increasing undercorrection of the far point of the eye over the course of a day, which brings about a deceleration in the axial length growth of the eyeball. In addition, a method for automatically adapting a corrective effect, a pair of spectacles, and a use of an ophthalmic lens are disclosed.
