1. A contact lens made from a polymerization product of a monomer mix comprising at least one siloxane-containing monomer and at least one vinyl-containing or acrylic-containing hydrophilic monomer,wherein the siloxane-containing monomer has vinyl- or acryl-functionality, and a polar fluorinated side group is attached to at least one silicon atom of the siloxane-containing monomer, said polar fluorinated side group having the general schematic representation:

  • 
    
    space="preserve" listing-type="equation">--D--(CF.sub.2).sub.z Hwhereinz is 1 to 20; and

    D is an alkyl or alkylene group having 1 to 10 carbon atoms and which may have ether linkages between carbon atoms.
