Abstract: An object is to provide a polarizing lens in which a polarizing function differs depending on the region of the surface of the lens. A polarizing lens that includes a polarizing layer on a lens base material and that includes a region in the surface of the lens in which the degree of polarization caused by the polarizing layer continuously differs or a region in the surface of the lens in which the film thickness of the polarizing layer continuously differs.

Abstract: Provision of a spectacle lens provided with a satisfactory degree of polarization from the perspective of ability to suppress glare, as well as with high luminous transmittance, the spectacle lens having a high degree of freedom of frame selection relative to the prior art, and enabling the reduction of the turnaround time from order receipt to delivery; and spectacles. A spectacle lens having a lens substrate and a dichroic pigment coating layer directly on the lens substrate or on the lens substrate via another layer, the spectacle lens having a degree of polarization of 10% to 60% and a luminous transmittance of more than 75%, and spectacles having the spectacle lens and a frame to which the spectacle lens is mounted.

Abstract: Provided is a spectacle lens endowed with high luminous transmittance as well as adequate polarizing function. A method for manufacturing a spectacle lens, comprising forming a polarizing layer by applying a coating liquid containing 0.04% by mass to 1.5% by mass of a dichroic pigment by a spin coating method at a speed of 200 rpm to 600 rpm on a rubbing-treated surface.
