Polymer Composition and Methods Using Said Polymer Composition to Manufacture Ophthalmic Lens |
摘要 |
The present invention proposes a polymer composition of manufacturing ophthalmic lens by polymerization of polymerizable composition wherein the shrinkage phenomenon is minimized. The polymerizable composition comprised two different categories of monomers which are able during crosslinking to control and limit said chemical shrinkage. The present invention comprises also ophthalmic lens obtained from said polymer composition using a manufacturing process of casting or additive manufacturing. |
