Title:
CONTACT LENS AND PRODUCTION METHOD FOR SAID LENS
Document Type and Number:
WIPO Patent Application WO/2022/270486
Kind Code:
A1
Abstract:
[Problem] To provide a contact lens having hydrophilicity, lubricity, and lipid adhesion resistance, and a production method for said lens. [Solution] It was found that the aforementioned problem can be solved, with the combination of a hydrophilic polymer including a specific composition and a contact lens base material including a specific composition, by a contact lens obtained by surface treating the contact lens base material, which has an epoxy group–containing silicone macromer in the make-up thereof, with the hydrophilic polymer.
