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.
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 monofocal contact lens (10) having an anterior surface (34) and a posterior surface is provided. The monofocal contact lens (10) includes an optic zone (30) providing monofocal optical properties located substantially in the center of the contact lens (10) and a peripheral zone (32) surrounding the optic zone (30). The peripheral zone (32) includes a three-dimensional pattern (35) placed on the posterior surface of the contact lens (10). The three-dimensional pattern (35) includes portions not in contact with the surface (33) of the eye (31).
