Abstract:
A simultaneous multifocal contact lens (10) for correcting vision acuity of an individual is disclosed. The contact lens comprises a central region (25) radially surrounded by at least one far vision focal region (30) and at least one near vision focal region (26), wherein a near vision additional correction of the at least one near vision focal region (26) is ovecorrected by at least 10 % with respect to the near vision additional correction prescribed for the individual according to the standard prescription for lens radius design.
Abstract:
A progressive multifocal lens for eyeglasses formed along a principle meridian curve, with a farsighted vision zone (1) having an optical power corresponding to that required for viewing distant objects, a nearsighted vision zone (3) having an optical power corresponding to that required for viewing near objects, and an intermediate vision zone (2) between and progressively connecting the farsighted vision zone and the nearsighted vision zone, includes a transparent, non-rotationally-symmetrical, microrelief structure in one or more of these vision zones.
