Abstract
The invention relates to a method for making an ophthalmic member for correcting ametropia, that is adapted for correcting the central and peripheral vision of a wearer and takes into account the amplitudes of the movements of the wearer's eyes and head. A central area of the member, in which the central vision is corrected, is sized based on the amplitude of the eyes' movements in order to provide good visual comfort. The peripheral vision is corrected in a peripheral area of the ophthalmic member in order to prevent an increase of the wearer's ametropia in the long run.
