Low water content soft lens for eye, and method for producing the same

A low water content soft lens for eye, comprising a base material, a layer made of an acidic polymer and a basic polymer being formed on at least a part of a surface of the base material, wherein the water content of the lens is 1% or less;

• wherein the layer made of an acidic polymer and a basic polymer is composed of one layer made of an acidic polymer and one layer made of a basic polymer, so two layers in total;
• or the layer made of an acidic polymer and a basic polymer is composed of one or two layers made of an acidic polymer, and one or two layers made of a basic polymer, and three layers in total;
• wherein the base material contain, as a main component, a polymer of the following component A, or a copolymer of the following components A and B:
• component A:
• a polysiloxane compound which has a plurality of polymerizable functional groups per molecule, and also has a number of average molecular weight of 6,000 or more, and
• component B:
• a polymerizable monomer having a fluoroalkyl group;
• the component A is a polysiloxane compound represented by the following formula (A1):
• wherein X1 and X2 each independently represents a polymerizable functional group;
• R1 to R8 each independently represents a substituent selected from hydrogen, an alkyl group having 1 to 20 carbon atoms, a phenyl group and a fluroalkyl group having 1 to 20 carbon atoms;
• L1 and L2 each independently represents a divalent group;
• and a and b each independently represents the number of the respective repeating units, and X3-and X2 in the formula (A1) are (meth)acryloyl groups.
