Abstract:
A laminate, including a substrate having a microstructure on a surface thereof; and a coating layer formed on the substrate and encapsulating the microstructure of the substrate. A glass transition temperature T1 of the substrate is higher than a glass transition temperature T2 of the coating layer. A method of producing an ophthalmic lens, including deforming the laminate into a shape of the ophthalmic lens by applying heat and/or pressure at a temperature of lower than T1.
