Zusammenfassung:	In securing adhesion of a hard coat layer to be formed on the surface of a plastic lens, modification of the lens surface is carried out without using an abrasive, and thereby the cleaning time after modification is shortened. A rubbing step (S1) to rub the surface of a plastic lens substrate using a removing member, and a step (S4) of forming a hard coat layer on the rubbed surface of the plastic lens substrate by means of a wet surface treatment are included. The removing member has flexibility, and is made of a hard material that is harder than the material of the surface of the lens substrate or has such constitution that a hard material is fixed on a base material having flexibility.
