Abstract
The present invention relates to a method of manufacturing a polarizing lens comprising: polishing in a constant direction one of surfaces of a first mold for forming one of surfaces of a lens; forming a polarizing film by coating a coating liquid containing a dichroic dye on the surface that has been polished; disposing a second mold, for forming the other surface of the lens, opposite the first mold with a prescribed gap therebetween, and forming a cavity by occluding the gap, wherein the two molds are disposed so that the polarizing film is positioned within the cavity; and casting a lens starting material liquid containing a curable component into the cavity and conducting a reaction to cure the curable component within the cavity to obtain a polarizing lens having the polarizing film on a lens substrate.
