    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: 8411907
    Abstract: A modification method and system. The method includes performing a computer processor of a computing system, a facial recognition process of an individual associated with a device. The computer processor retrieves from a detection device, eyewear detection data indicating that the individual is correctly wearing eyewear and tint detection data indicating that the eyewear comprises tinted lenses. In response, the computer processor analyzes results of the facial recognition process, the eyewear detection data, and the tint detection data. The computer processor modifies functions associated with the first device in response to results of the analysis.

  • Patent number: 8403478
    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: 20130070196
    Abstract: Provided is a polarizing lens which is excellent especially in terms of impact resistance, appearance, and prevention of eye strain and which has high precision of the surface shape. The polarizing lens is formed by laminating a sheet of an aromatic polycarbonate through an adhesive layer to each surface of a film having polarizing properties, curving the resultant laminate so as to impart spherical or aspherical surfaces thereto to obtain a polarizing sheet, inserting the polarizing sheet into a mold, and injecting an aromatic polycarbonate, wherein the polarizing sheet is obtained through the laminating so that the stretch axis of one of the aromatic-polycarbonate sheets is perpendicular to the absorption axis of the film having the polarizing properties.

  • Publication number: 20120287395
    Abstract: In order for the discolored laminated glass lens for spectacles to have excellent glare-prevention characteristics, a tetraazaporphyrin compound is combined at a required concentration with an extremely thin adhesive agent layer in a manner so that unevenness of color does not arise, and of the light-absorbing ability expected for a laminated lens for spectacles. There is sufficient shielding of light in the vicinity of the 585 nm wavelength. In the laminated glass lens for spectacles, two glass lens substrates (2 and 3) (each about 1 mm thick) are bonded together with an adhesive agent layer (1) therebetween. A liquid substance of a solventless adhesive to which a pigment containing a tetraazaporphyrin compound is added together with an organic solvent is dropped onto the glass lens substrate (2) in the form of a droplet (1a; shown by phantom line in FIG.

  • Patent number: 8311635
    Abstract: The present invention is a system for mapping a high resolution image to a lower resolution electrode array and, by applying varying stimulus to neighboring electrodes, creating a perceived image greater in resolution than the electrode array. The invention is applicable to a wide range of neural stimulation devices including artificial vision and artificial hearing. By applying a sub-threshold stimulus to two neighboring electrodes where the sum of the stimuli is above the threshold of perception, a perception is created in neural tissue between the two electrodes. By adjusting the stimulus on neighboring electrodes, the location of stimulation can be altered. Further, noise can be applied to the stimulating electrode or its neighboring electrodes to reduce the threshold of stimulation.

  • Publication number: 20120262665
    Abstract: Curved lenses and methods for making curved lenses are described. One embodiment of a method of making a curved lens includes curving a lens blank made of a linear polarizer layer laminated together with a plurality of polymeric layers. The lens blank is curved by heating and pressing the lens blank between a convex member and a concave member at a first pressure, ramping the pressure sigmoidally to a higher pressure over a period of time, and maintaining the higher pressure for a time sufficient to allow the lens blank to conform to the shape of the convex member and concave member. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.
