PROBLEM TO BE SOLVED: To provide a method for producing plastic lens by which the fraction defective is reduced by making flaws in a plastic lens substrate invisible and the production efficiency is enhanced. SOLUTION: In a step for forming a hard coat film or a primer and the hard coat film on the surface of a plastic lens substrate, a step for heat-treating the plastic lens substrate is carried out before the substrate is coated with the hard coat or the primer. |
