METHOD OF MAKING ARTICLES OF DISSIMILAR POLYMER COMPOSITIONS |
摘要 |
Hybrid contact lenses and other composite polymeric articles of precise dimensions are made by placing a first monomer composition in a mold and irradiating and polymerizing a central portion only with ultraviolet radiation. Unpolymerized monomer is removed, a second monomer composition is placed in contact with the polymer formed from the first monomer composition and the latter is polymerized by ultraviolet irradiation or by other means to obtain a composite article which is then machined to form a hybrid lens. |
