  • Publication number: 20190324294
    Abstract: Provided is a lens that includes a lens body and an internal electrode at least a part of which is exposed to an outer edge part of the lens body. The lens is configured so that in the outer edge part of the lens body, the shape of a first region that includes an exposed part where the internal electrode is exposed and the shape of a second region that does not include the exposed part are different. This configuration makes it possible to provide a lens that can be easily attached to a frame.

  • Patent number: 8979262
    Abstract: A semi-finished blank for a varifocal lens, as well as a varifocal lens and varifocal eyeglasses, have power consumption reduced and avoid a decrease in commercial value. A first substrate has a first transparent conductive film that is produced on the front face of this first substrate. A second substrate that is opposite the first substrate has a second transparent conductive film that is produced on the back face of this second substrate. A varifocal portion is disposed between the front face of the first substrate and the back face of the second substrate. The first transparent conductive film is separated by laser into a first region that includes a region that is opposite the varifocal portion, and a region other than this first region.
