    Abstract: A laser reflecting has a low transmittance at one or more laser wavelengths while substantially transmitting all other wavelengths in the spectral range of interest, is coated on one or both sides of an absorbing or non-absorbing substrate. A laser reflecting filter on both sides of an absorbing substrate can result in an enhancement of the absorption of laser light by multiple reflections of the laser light in the absorbing substrate. The high transmittance of the laser-reflecting filter at non-laser wavelengths results in a relatively high overall transmittance through the coated substrate. In the specific case of laser reflecting coatings on a lens to protect an eye, this allows a high luminous transmittance and good colour discrimination.

  • Publication number: 20140118681
    Abstract: A process for making a temporary photochromic patch for an ophthalmic lens. A photochromic dye is dissolved in either a siloxane base or curing agent. The base and curing agent are combined to initiate a polymerization reaction that will result in a polydimethylsiloxane (PDMS) polymer matrix having sufficiently low molecular weight to accommodate the photochromic dye's mobility. The polymerization reaction is completed in a form to create a viscoelastic patch. The resulting patch can be trimmed and temporarily applied to an ophthalmic lens without needing adhesive.

  • Publication number: 20140055736
    Abstract: An improved lens with Rugate filter specifically designed to be worn in prescription and non-prescription glasses, contact lenses, intraocular lenses and sunglasses, and to provide protection against macular degeneration by reducing harmful visible blue light transmission and ocular photochemical damage. The lens at least includes a single lens layer with a Rugate filter deposited thereon to selectively block visible blue light. Other layers may be added including a polarizing layer, dielectric layer and/or color tint in a lens sandwich configuration, to additionally give a high degree of UVA and UVB protection, color contrast, and glare reduction. The Rugate filter is a stop band which yields an exceptional light transmission profile under all light conditions, thereby maximizing protection as well as clarity of vision.

  • Publication number: 20130282115
    Abstract: An improved dual-filter lens for protective eyewear that combines a first filter for blocking essentially 100% of UV light, and second filter for filtering blue light. The first filter may comprise a multi-layered dielectric mirror layer 14 or Rugate filter 50, and the second filter may comprise dye-impregnated lens layer(s) 16, 18 or Rugate filter 50. The first filter blocks essentially 100% of UV light, while the second filter establishes an increasing transmission profile that cuts on sharply at approximately 415 nm, and establishes an increasing transmission profile between approximately 415 nm to about 475 nm. The cut-on slope rises approximately 0.15% in transmissivity for every nanometer of increasing wavelength change, with a maximum filtering effect within the 440-465 nm range. These dual filters provide a balanced light transmission profile that reduces harmful tight transmission and prevents macular degeneration, cataracts and other ocular injuries, while still preserving visual acuity.

  • Patent number: 8545010
    Abstract: The present invention relates to dual-lens eyeglasses including an eyeglass frame and two lens units permanently installed on the eyeglass frame. Each lens unit includes two lenses arranged in optical alignment with each other. The lenses can be optical lenses or sunglass lenses. The optical lenses can be selected from known lenses such as corrective lenses, myopic corrective lenses, reading glasses lenses, progressive lenses, etc. The sunglass lenses can be selected from polarized lenses, tinted lenses, or photochromic lenses. Without the use of sub-frames, two lens units are permanently installed on eyewires of the eyeglass frames, enhancing the integration effect of the eyeglass frames. In addition, each lens is directly fixed and installed on the eyeglass frames, so that the installation is reliable and the lenses will not fall off easily. Furthermore, the lenses can be easily installed on full-rim, half-rim or rimless eyeglass frame.
