摘要：
A low water content soft lens for eye is provided, which includes a layer made of an acidic polymer and a basic polymer on at least a part of a surface of a base material containing a polysiloxane compound. Adhesion of the lens to the cornea during wear, which has hitherto been regarded as a problem in a conventional low water content soft lens for eye, can be reduced or avoided when using the low water content soft lens.
