  • Surgical optical lens
    Patent number: 11966034
    Abstract: A body tissue observation lens includes a lens base having an integral polarizing filter. The body tissue observation lens has a 40% or higher average transmittance in a visible light wavelength range of 380 to 780 nm. The body tissue observation lens contains a specific wavelength light absorbing pigment such that the ratio of the minimum transmittance in a wavelength range of 580 to 600 nm to the average transmittance in the visible light wavelength range of 380 to 780 nm is 18 to 50%.

  • Non-corrective plastic spectacle lens
    Patent number: 11543684
    Abstract: The present invention provides a non-corrective spectacle lens which is a molded plastic lens used by a person having normal eyesight, or a polarizing lens constituted by the molded plastic lens and a polarizing film integrally superposed on the molded plastic lens. In order to moderately reduce the movement of the muscle necessary for focus adjustment, the non-corrective spectacle lens has a spherical power S within the range of ?1.0 D?S<?0.1 D, where D is diopter as a unit of the spherical power S.
