摘要： A process of producing a plastic lens having a high refractive index, a high Abbe's number and good mechanical strength and a plastic lens obtained by that process. A process of producing a plastic lens including a step of polymerizing a mixture of (1) a prepolymer obtained by mixing and reacting from 0.1% by weight to 10% by weight, based on the whole amount of the mixture, of sulfur and an epithio group-containing compound, (2) a polyisocyanate compound, and (3) a polythiol compound; and a plastic lens obtained by this process.
