PROBLEM TO BE SOLVED: To obtain a primer composition for a plastic lens for providing a plastic spectacle lens excellent in various qualities such as appearance, wear, heat, moisture, shock and weather resistances, adhesion between the lens substrate and a surface treating layer and durability and to impart superior appearance and enhanced shock resistance, adhesion and weather resistance particularly to a plastic lens substrate having a high refractive index. SOLUTION: When a primer layer and a hard coat layer are successively disposed on the surface of a plastic lens substrate or an antireflection film is further disposed on the surface of the hard coat layer to obtain a plastic lens, a polythiourethane resin formed with a primer composition for a plastic lens consisting essentially of a blocked isocyanate and a polyol is used for the primer layer.
