Zusammenfassung:	1. Contact-optical items, especially contact lenses and scleral lenses, composed of water-absorbing, crosslinked copolymers of olefinically unsaturated monomers, characterized in that the copolymer contains polymerized in 5 to 55% by weight of a N-vinylamide of the general formula see diagramm : EP0184729,P6,F2 in which R and R' represent, independently of one another, C1 -C4 -alkyl groups.
