    Abstract: This eyeglass lens is outstanding in anti-crazing properties, impact resistance properties, and adhesion. The present invention comprises: a lens substrate; a primer layer disposed on the lens substrate; and at least one layer that is disposed on the primer layer and that is selected from the group consisting of a hard-coat layer and a reflection-preventing layer. The primer layer contains a polycarbonate-based polyurethane resin and inorganic oxide particles. The tensile strength of the polycarbonate-based polyurethane resin is over 40 N/mm2. The expansion rate of the polycarbonate-based polyurethane resin is at least 300%, and the inorganic oxide particle content is 10-40% by volume with respect to the total volume of the primer layer.

    Abstract: The present invention provides a spectacle lens having low surface resistivity. This spectacle lens includes a spectacle lens base and a hard coat layer. When a primer layer is included between the spectacle lens base material and the hard coat layer, the primer layer and/or the hard coat layer contains at least one type of electroconductive filler selected from the group consisting of ionic liquid-coated nanowires containing metal nanowires and an ionic liquid coating the metal nanowire, and ionic liquid-coated nanoparticles containing metal nanoparticles and an ionic liquid coating the metal nanoparticles. When the primer layer is not included between the spectacle lens base material and the hard coat layer, the hard coat layer contains the at least one type of electroconductive filler selected from the group consisting of the ionic liquid-coated nanowires and ionic liquid-coated nanoparticles.
