    摘要: Fumaric acid derivatives and ophthalmic lenses using them are disclosed. More specifically, a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and contact lenses or intraocular lenses using the same are disclosed. The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.
