摘要

P to generate a surface of refraction of an ophthalmic lens has a progressively variable power, in which will determine, in a system of reference, a family of surfaces having the optical characteristics predetermined. / p & & p & will determine, in the same system of reference, a second family of the surfaces s having other characteristics, predetermined, it associates each surface s of the first family has a surface s and will determine the curves of intersection c and d, it is chosen from among the pairs of surfaces ss, that in which the curves c and d spare between them a passage, respectively, of at least 15 and 18 mm in width in the zones of the intermediate vision z and z of pressure, and it is, for the surface of refraction s, the part of the surface s of the selected pair, which is located between the curves c and d, and the part of the surface s of the selected pair, which is located at the packaging of the curves c and d / p
