摘要

THIS IS A ophthalmic lens PROGRESSIVE the front face (11), for example UNDERSTANDS, Monolithic, ONE PART, a central area (14), having a progressively variable curvature FOLLOWS at least a portion of at least one MERIDIAN IS THE oPTICALLY AREA UTIL, and MOREOVER, surrounding this central area (14), a peripheral zone COUPLING (15) engaging tangentially ESTA. According to the invention, the central zone OPTICALLY UTIL (14) of this front face (11A) is bounded by A SHARP TURN THAT projection on a plane perpendicular to the axis GEOMETRIC SET, is generally oval-shaped, and the radius of curvature of THE RADIAL SECTION OF pERIPHERAL DOCKING YOUR AREA (15) varies circumferentially VALUE AND / OR sIGN SO THAT ALONG peripheral edge (13) LENS is generally the same thickness. OBTAINING APPLICATION IN PROGRESSIVE OPHTHALMIC LENSES easier to perform, more aesthetically pleasing and lighter.
