Method for producing a high refractive index polarizing lens

To provide a method for manufacturing a polyisocyanate and consisting of polythiol polyurethane high-refractive index polarizing lens inconvenience generation of bubbles and excellent without adhesion. In the method of producing a high refractive index polarizing lens comprising forming a lens layer comprising a formed from polyisocyanate and polythiol to both surfaces of the polarizing film polyurethane polymers, moisture content is 4.5 wt% or less as the polarizing film method for producing a high refractive index polarizing lens, which comprises using a polarizing film is.
