Document Type and Number:
WIPO Patent Application WO/2023/276858
Kind Code:
A1
Abstract:
[Problem] To provide a soft contact lens solution that imparts, to a soft contact lens, surface hydrophilicity, lubricity, and lipid-adhesion-suppressing ability. [Solution] It was found that said problem can be solved by a solution containing a buffer and two specific copolymers, resulting in the completion of a soft contact lens according to the present disclosure.
