Soft contact lenses

A soft contact lens made of a copolymer consisting essentially of:

• (a) from about 30 to about 60 parts by weight of the total momoner mixture of at least one momoner selected from the group consisting of long chain alkyl acrylates and methacrylates represented by the general formula:
• ##STR3## where R.sub.1 is a hydrogen atom or a methyl group, and R.sub.2 is a straight chained or branched alkyl group having from 5 to 18 carbon atoms;
• (b) from about 40 to about 70 parts by weight of the total monomer mixture of at least one hydrophilic monomer selected from the group consisting of dimethylacrylamide, N-vinylpyrrolidone, a hydroxyalkyl acrylate and a hydroxyalkyl methacrylate;
• and
• (c) from about 0.05 to about 2.0 parts by weight of the total monomer mixture of a cross-linking agent selected from the group consisting of ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate, allyl methacrylate, trimethylolpropane trimethacrylate, divinyl benzene and diallylphthalate;
• wherein the said copolymer has a water content of from 25 to 50% by weight.
