    • G02C13/00
    • PROBLEM TO BE SOLVED: To provide a precare agent composition for contact lenses which prevents the adhesion of smudge, such as protein, to the lenses arising during wearing of the contact lenses, imparts the feel of dampness to the lenses, and suppresses the degradation in the feel of wearing, such as the dryness of the eyes, and a precare method.
      SOLUTION: The precare agent for contact lenses contains (A) a monomer having an amino group and/or a monomer having a quaternary ammonium group, (B) (meth)acrylate monomer, (C) a vinyl lactam monomer, and (D) a polymer compound prepared by copolymerizing one or two or more nonionic hydrophilic monomers exclusive of the aforementioned (A), (B) and (C) at specific ratios.
