PROBLEM TO BE SOLVED: To provide a method for producing a plastic lens which is obtained by polymerizing a composition containing a compound having at least one episulfide group in a molecule as a main component and curing the polymer, stable in dioptric power, resistant to yellowing, and easy of handling during the polymerization and the plastic lens produced by the method. SOLUTION: When the plastic lens is produced by polymerizing the composition and curing the polymer, a polymerization pattern in which the highest polymerization temperature is 125-140 deg.C is used. |
