    Abstract: A bifocal or multi-focal contact lens (5) having a geometrical lens center point (4) comprises a near-circular near vision zone (10) having a first geometrical center point and a near-circular far vision zone (8) having a second geometrical center point. The near vision zone (10) and the far vision zone (8) are concentrically arranged, whereby the first geometrical center point and the second geometrical center point coincide and form a common correction center (6) and said correction center (6) is located at a distance from the lens center point (4). Said contact lens (5) ensures optimized visual acuity without intermediate zones, in particular in the case of presbyopia. Furthermore, said contact lens can be produced in a simple and low-cost manner.
