Abstract:
An aspect of the present invention relates to a method of manufacturing a polarizing eyeglass lens comprising forming an orientation layer on a substrate, sliding a rubbing member across the orientation layer in a state of contact with the orientation layer to form curved rubbing traces on a surface of the orientation layer, forming a polarizing layer by depositing and orienting a dichroic dye on the orientation layer, and subjecting the polarizing layer to a treatment of immobilizing the dichroic dye in the polarizing layer.
