摘要:
A contact lens article comprises a resin obtained by copolymerizing starting monomer components containing a silicon-containing compound (A) represented by the formula ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group, X.sub.1 and X.sub.2 each represent a methyl group or ##STR2## l represents 0 or 1, m represents an integer of 1 to 3 and n and p each represent an integer of 0 to 3; a fluorine-containing compound (B) represented by the formula (II) of: ##STR3## wherein at least one of R.sub.2 and R.sub.3 represents a straight chain or branched chain fluoroalkyl group represented by --C.sub.h H.sub.k F.sub.2h+l-k in which h represents an integer of 2 to 18, k represents an integer of 1 to 2 multiplied by h and when one of R.sub.2 and R.sub.3 is --C.sub.h H.sub.k F.sub.2h+l-k, the other of R.sub.2 and R.sub.3 represents an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 2 to 12 carbon atoms or a cycloalkyl group having 3 to 12 carbon atoms; and a radical polymerizable vinyl monomer.
