Abstract

The invention relates to a presbyopia-correcting lens, particularly a contact lens or intraocular lens, and a method for producing such a lens. At least one near vision zone having high refractive power and at least one far vision zone having low refractive power are arranged on said lens so as to provide simultaneous near vision and far vision. Said near vision and far vision zones merge by means of a transition area. The inventive lens is characterized by the fact that the at least one near vision zone and the at least one far vision zone are arranged in a rotationally asymmetric manner on the lens while the transition area is about centrally located on the lens and the distribution of the refractive power is approximately coma-shaped. The inventive production method allows client-specific lenses to be produced with a similar distribution of the near vision and far vision zones, the transition area being centered approximately in front of the pupil (optical axis) of the eye.
