Abstract: A bifocal contact lens has a viewing area divided into a plurality of near vision zones (1,3A) and distance vision zones (2,2A, 3) which are substantially concentric with respect to the optical axis (P,Q) of the lens. Each near vision zone is adjacent to a distance vision zone or to a middle distance zone and at least one of the near vision zones comprises an aspherical lenticular surface. An important advantage of the lens is that the aspherical surface can be merged into an adjacent spherical surface with less discontinuity at the junction between the adjacent zones.
