Abstract: Contact lenses having position stabilization are utilized in order to fix the position of the contact lens on the cornea of the eye of a person wearing the lens. For this purpose, thickened regions for adjusting a specific orientation relative to the eye of the wearer are provided on the convex outer surface of the contact lens outside of the optical zone. A reliable position stabilization of a contact lens on the eye is achieved in that at least two thickened regions are provided laterally of the vertical center axis. These thickened regions extend essentially below a horizontal center axis between the optical zone and the edge region and it is very advantageous if these thickened regions lie at least at one point on the lower eyelid when the eye is open. In this way, a rotation of the contact lens is avoided when the eye is open. Furthermore, it is advantageous when the contact of the thickened regions on the lower eyelid is maintained.
