Abstract: A method for manufacturing a polarizing lens that includes a polarizing polyvinyl alcohol film arranged between two pieces of a lens base material. The method includes subjecting the polarizing lens to edging processing to prepare a polarizing lens where the polarizing polyvinyl alcohol film is exposed at least at a part of an edge surface of the lens, and applying hydrophobization treatment to the polarizing polyvinyl alcohol film exposed at the edge surface of the lens.
