Kind Code:
A1
Abstract:
This optical film 5 (a laminate body for an eyeglass lens) is used while disposed on the front surface 41 of an eyeglass lens 4. The optical film 5 includes: a light-transmissive protective layer 52; a coloring layer 51 provided on the rear side of the protective layer 52 and containing a coloring material 512 that produces a color when irradiated with laser light; and a polarization layer 53 provided on the rear side of the coloring layer 51 and polarizing the incident light entering through the protective layer 52 and the coloring layer 51. As a result, it is possible to provide a laminate body for the eyeglass lens and an eyeglass lens with a laminate body wherein the printed part of the coloring layer can be prevented from fading out. It is also possible to efficiently apply a marking to the laminate body for the eyeglass lens and to the eyeglass lens with the laminate body.
