Abstract

Provided is a lens solution which has excellent lipid detergency, exhibits high hydrophilization performance, and exhibits an excellent lipid adhesion preventive effect and an excellent lubricity-imparting effect when the solution is used to coat a lens. Disclosed is a lens solution containing a polymer having 2.5% to 95% by mass of the following repeating unit (A) and 2.5% to 95% by mass of the following repeating unit (B):

• • (A) a hydrophilic repeating unit; and
  • (B) a repeating unit having a polyoxyalkylene group in a side chain and having the end of the side chain formed from an alkyl group having 5 to 30 carbon atoms, an alkanoyl group having 5 to 30 carbon atoms, or an aryl group.

Claims

1. A solution comprising a polymer having 2.5% to 95% by mass of the following repeating unit (A) and 2.5% to 95% by mass of the following repeating unit (B):

(A) a hydrophilic repeating unit; and

(B) a repeating unit having a polyoxyalkylene group in a side chain and having the end of the side chain formed from an alkyl group having 5 to 30 carbon atoms, an alkanoyl group having 5 to 30 carbon atoms, or an aryl group.

2. The solution according to claim 1, wherein the repeating unit (A) is one or more selected from the group consisting of a repeating unit (A-1) having a polyoxyalkylene group in a side chain and having the end of the side chain formed from a hydrogen atom or an alkyl group having 1 to 4 carbon atoms;

a repeating unit represented by the following formula (3) (A-2);

a repeating unit represented by the following formula (4) (A-3);

a repeating unit represented by the following formula (5) (A-4);

a repeating unit represented by the following formula (6) (A-5);

a betaine-like repeating unit represented by the following formula (7) (A-6);

an anionic repeating unit (A-7); and

a cationic repeating unit represented by the following formula (8) (A-8);

3. The solution according to claim 1, wherein the repeating unit (A-1) is represented by the following formula (2):

4. The solution according to claim 1, wherein the repeating unit (B) is represented by the following formula (10):

5. The solution according to claim 1, wherein the polymer further comprises 40% by mass or less of a repeating unit (C), the repeating unit (C) being one or more selected from the group consisting of a repeating unit represented by the following formula (11) (C-1), and a repeating unit having a group represented by the following formula (12) at the end of a side chain (C-2):

6. The solution according to claim 1, wherein the polymer is a water-soluble polymer.

7. The solution according to claim 6, formulated for cleaning or storage of a contact lens.

8. The solution according to claim 7, comprising 0.001% to 10% by mass of the polymer.

9. The solution according to claim 1 formulated, for coating a contact lens.

10. A method for producing a surface-modified contact lens, comprising bringing the solution according to claim 1 into contact with at least a part of a contact lens surface.

11. A contact lens comprising, in at least a part of the surface, a polymer containing 2.5% to 95% by mass of the following repeating unit (A) and 2.5% to 95% by mass of the following repeating unit (B):

(A) a hydrophilic repeating unit; and

(B) a repeating unit having a polyoxyalkylene group in a side chain and having the end of the side chain formed from an alkyl group having 5 to 30 carbon atoms, an alkanoyl group having 5 to 30 carbon atoms, or an aryl group.
