Abstract: A polarizing lens including a polarizing polyvinyl alcohol film arranged between two pieces of a lens base material, where the polarizing polyvinyl alcohol film includes a hydrophobic region having higher hydrophobicity than other regions at least at a partial region of an outer periphery part including an edge surface thereof and the hydrophobic region is exposed at least at a part of an edge surface of the lens.

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.
