Title
(EN) CONTACT LENS TREATMENT SOLUTION
(FR) SOLUTION DE TRAITEMENT DE LENTILLE DE CONTACT

Abstract
(EN)
The present invention is a contact lens treatment solution characterized by comprising a copolymer A and a copolymer B in the ratio A:B = 1000:1 to 2:1 (weight ratio). With the present invention, it is possible to provide a contact lens treatment solution that, by means of a simple immersion process, can remove dirt adhered to a contact lens surface and can impart continuous hydrophilicity to the contact lens surface. Copolymer A: a copolymer obtained by copolymerizing a monomer a represented by formula 1 and a monomer b represented by formula 2, wherein the copolymerization ratio of the monomer a and the monomer b is a:b = 7:3 to 9:1 (molar ratio), and the weight average molecular weight is 400,000 to 700,000. Copolymer B: a copolymer obtained by copolymerizing a monomer c represented by formula 3 and a monomer d represented by formula 4, wherein the copolymerization ratio of the monomer c and the monomer d is c:d = 1:4 to 9:1 (molar ratio), and the weight average molecular weight is 20,000 to 90,000.

La présente invention concerne une solution de traitement de lentille de contact caractérisée en ce qu'elle comprend un copolymère A et un copolymère B dans le rapport A : B = 1000 : 1 à 2 : 1 (rapport en poids). Au moyen de la présente invention, il est possible de fournir une solution de traitement de lentille de contact qui, au moyen d'un procédé d'immersion simple, peut éliminer les salissures adhérant à une surface de lentille de contact et peut conférer un caractère hydrophile continu à la surface de lentille de contact. Le copolymère A est un copolymère obtenu par copolymérisation d'un monomère a représenté par la formule 1 et d'un monomère b représenté par la formule 2, le rapport de copolymérisation du monomère a et du monomère b étant a : b = 7 : 3 à 9 : 1 (rapport molaire), et le poids moléculaire moyen en poids étant de 400 000 à 700 000. Le copolymère B est un copolymère obtenu par copolymérisation d'un monomère c représenté par la formule 3 et d'un monomère d représenté par la formule 4, le rapport de copolymérisation du monomère c et du monomère d étant c : d = 1 : 4 à 9 : 1 (rapport molaire), et le poids moléculaire moyen en poids étant de 20 000 à 90 000.
