发明名称 Method of producing contact lens with identifying mark permeating into lens.
摘要 <p>A method of producing a contact lens provided with an identifying mark (12) us disclosed. According to this method, a printing liquid is first prepared by dissolving a pigment in an organic solvent which is permeable into the material (10) for the contact lens. This printing liquid is applied to a predetermined portion of a lens surface of the contact lens, such that the printing liquid permeates into an interior of the lens, to thereby form a colored region on the lens surface. The colored region thus formed consists of a first portion (14) permeating into the interior of the lens, and a second portion (16) protruding from the lens surface. Then, the second portion of the colored region is removed so as to smooth the lens surface, whereby the identifying mark is constituted by the first portion of the colored region. &lt;IMAGE&gt;</p>
