Abstract: The invention relates to the determination of a pair of ophthalmic lenses, by measurement of the sagittal plane shift of the wearer for close vision with relation to the standard sagittal plane. Optimisation targets are then chosen as a function of the measured shift. The lenses are determined by optimisation with the chosen targets. Lenses are thus obtained with which the field of close vision is symmetrical with relation to the medial line as perceived by the wearer. A wearer with a displaced sagittal plane thus has a greater close vision field which facilitates binocular vision and increases acuity.
