The silicone contact lens having a radial cross section of an inner surface (1) of the contact lens and an edge region contour of the cross section between a turning point (6) and a convex outer edge (7), is claimed, where silicone contact lens is coated in a hydrophilizing manner. A water contact angle of the contact lens is less than 10[deg] . A minimum radius of the convex cross-sectional contour is 0.5 mm. A hydrophilizing layer consists of (meth)acrylic acid units, and has a thickness of 1 mu m. The edge region of the contact lens is 0.01-0.1 mm wide. The silicone contact lens having a radial cross section of an inner surface (1) of the contact lens and an edge region contour of the cross section between a turning point (6) and a convex outer edge (7), is claimed, where silicone contact lens is coated in a hydrophilizing manner. A water contact angle of the contact lens is less than 10[deg] . A minimum radius of the convex cross-sectional contour is 0.5 mm. A hydrophilizing layer consists of (meth)acrylic acid units, and has a thickness of 1 mu m. The edge region of the contact lens is 0.01-0.1 mm wide. An outer edge of the contact lens has an irregularity such that the contact lens has an average square deviation of 5000 mu m 2>associated with the outer edge according to a criterion of a lowest average square deviation. An independent claim is included for a method for producing a silicone contact lens.
