    摘要: Disclosed is a method for optical design of a pair of ophthalmic lenses for correcting spherical and cylindrical refractive errors of the eyes of a wearer, including a step of defining the need for spherical and cylindrical correction of the wearer for various viewing distances, and a step of determining the spherical and cylindrical power of the ophthalmic lenses at viewing points with various proximities, in accordance with the correction needs of the wearer. The power of at least one of the two ophthalmic lenses is determined such as to limit the deviation obtained therebetween upon adding equivalent spherical power between the viewing points with various proximities and/or varying the cylindrical power vector between the viewing points with various proximities. Also disclosed is a pair of ophthalmic lenses designed according to such a method.
