Abstract

The multifocal contact lens comprises the central area with an inner surface arranged with spherical curvature or one or more coaxial aspherical curvature-consecutive areas. The aspherical curvature of a consecutive area or areas has a progressive eccentricity where there is a progressive measurement of eccentricity of a coaxial consecutive area or areas in limits from 0.01 to 0.03 for one deviation scope of the corresponding radius of lens curvature.
