PROBLEM TO BE SOLVED: To obtain a dynamic stabilization contact lens which is comfortable to a wearing person by providing this lens with an outer convex face and inner concave face including variable shape lens zones. SOLUTION: The lens 10 has a convex outer face and a concave inner face. The concave face is installed at the cornea of the wearing person. The central visual zone 11 exists on the convex face or outer face of the lens 10 and its center is a lens center. The visual zone 11 may be any desired shape, such as a spherical, spherical multifocal, annular, annular multifocal or aspherical shape corresponding to the visual magnification of the prescription necessary for the wearing person. In such a case, a non visual lens zone 12 encloses the central visual zone 11. The lens zone, more preferably the convex face lens zone 12 are variable shapes. The connecting part of the central visual zone 11 and the lens zone 12 may be any convenient shape by the shape of the lens zone to be used. In addition, an undesirable area is preferably compensated by disposing a migration zone 14 between the central visual zone 11 and the lens zone 12.
