Document Type and Number:
Japanese Patent JP6723406
Kind Code:
B2
Abstract:
The present invention provides a hydrophilic coating method for contact lens surface, firstly performing a hydration procedure S1 to form a hydrated polymer from a non-hydrated polymer, then sequentially contacting the hydrated polymer with a first solution and a second solution containing a high molecular compound at a specific temperature between 50° C. and 70° C. to complete a first hydration process S2 and a second hydration process S3. A contact lens 1 obtained according to the above procedures has a contact angle ranging from about 30° to 65°, and proteins and lipids are not easily deposited on a surface of the contact lens 1, thereby providing the user with good comfort when wearing.
