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.

Abstract: In a door opening and closing device for a vehicle, a handle case is mounted on an outer panel of a door, an arm portion of an outer handle that can be operated on the door extends through the handle case, penetrates into the outer panel, and is pivotably supported on the handle case, and a return spring is provided between the handle case and a pivoting member that is disposed on the handle case, pivotably supported on the handle case, and operatively linked to the outer handle. The device includes a dust proof wall surrounding a coil portion of the return spring. Accordingly, even when foreign matter enters an interior of the outer panel of the door through a gap between the arm portion of the outer handle and the handle case, it is possible to inhibit foreign matter from being caught in the return spring.

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 having, on at least one side of a lens substrate, a polarizing layer containing a dichromic pigment, and a photochromic layer containing a photochromic pigment, and having the polarizing layer and the photochromic layer via an intermediate layer.
