Abstract

A method of manufacturing a plastic lens includes: a step of putting a first curable composition over a forming surface of a first mold substrate having the forming surface for forming a lens surface; a step of spreading the first curable composition over the entire forming surface by pressing the composition with a film to form a first curable composition layer and separating the film from the first mold substrate by a predetermined distance through the formed first curable composition layer; a step of covering defined surfaces; a step of injecting a second curable composition into a defined location; a step of curing the first curable composition layer and the injected second curable composition; and a step of removing to obtain a plastic lens.
