A plastic lens manufactured from a plant-derived raw material, having high heat resistance, high transparency, high Abbe number, high strength, high dyeability, and low birefringence is provided. The main component is a polycarbonate resin containing a structural unit derived from a dihydroxy compound (such as isosorbide) represented by the following formula (1) and having a reduced viscosity of 0.2 to 1.5 dl / g. An optical lens such as a spectacle lens is obtained by injection molding using the material. [Selection figure] None |
