(57) [Summary] [Purpose] To obtain a plastic lens having no optical distortion, high productivity in a short time, and having excellent transparency, impact resistance, heat resistance, surface hardness and chemical resistance. [Structure] A composition for a specific plastic lens is formed by a first step of partially polymerizing with an active energy ray to make it non-fluidized, and a second step of subsequent polymerization to complete polymerization. Manufacturing method of plastic lens. |
