Abstract:
Ophthalmic lens including at least one spherical face with an optical center and a geometrical center, and having in succession a top vision region, an intermediate vision region and a bottom vision region, with a principal meridian of progression traversing the three vision regions of the aspherical face, the lens being noteworthy in that the top vision region is adapted for mid-distance vision, the bottom vision region is adapted for near-distance vision, and the intermediate vision region is adapted for intermediate distance vision, and in that the optical center of the aspherical face is in the intermediate vision region, the optical center coinciding with the geometrical center of aspherical face. This lens is particularly suitable for people with emmetropic longsightedness.
