Definitions

  • the most common support materials are stainless steel and chromium- plated surfaces.
  • Important items for belt and drum machines are the material's heat conductivity, the technical processes used to create the required surface finish, and the options for repairing small surface defects.
  • This cast technique may allow for the simple production of films with structured surfaces.
  • the belt surface may be clearly and accurately replicated on one surface of the film.
  • the techniques used to adapt the surface of the drums or belts to highly glossy, structured, or matt film finishes are proprietary methods.
  • the thin dyed optical film is capable of functioning as an eyewear lens, a vehicle window, a camera lens, a microscope lens, a building window, an electronic screen, a lamp cover protection, a phone screen, a TV screen, a computer screen, or an appliance equipment.
  • the thin, dyed optical film is laminated into a glass lens or a plastic lens.
  • a vacuum coating is applied to said thin, dyed optical film.
  • an anti-Reflective coating is applied to said thin, dyed optical film.
  • a hard coating is applied to said thin, dyed optical film.
  • a water-resistant coating is applied to said thin, dyed optical film.
  • the methods and systems of making a functional film disclosed herein provides many important advantages over those of prior arts. Specifically, the current application yields a virtually isotropic, flat, and dimensionally stable functional film. Furthermore, the functional film achieves maximum optical purity and extremely low haze. The film is also dyed to a precise specification without being affected by dye degradation problems. As a result, the present functional film has less treatment, less defect, less delamination, and less stress, and, thus, the optical lens requires fewer layers, and process time is shorter.
  • the current method uses readily incorporated mixture components used in traditional methods. The current application does not increase material costs, and, in certain cases, it actually reduces material costs because it yields accurate optical properties, specifications, and thinness in functional films, which, in turn, reduce the number of layers in an optical lens.
  • a plastic polymer such as TAC, Cellulose acetate, Cellulose propionate, Polyurethane, PVC, Silicon urethane copolymer, Acrylic, COP, Tetrafluoroethylene polymer, PC, PP, PE, PET, Polyethersulfon, Poly etherimide, and Polyvinylidene fluoride
  • an appropriate solvent 102 such as triphenyl phosphate, diphenyl phosphate, dichloromethane, methanol, resorcinol, tetraphenyl diphosphate, acetone, butanol, butyl acetate, butanol, Biphenyl diphenyl phosphate, Trichloromethane, MEK, EAC, IP A, MIBK, BCS, MCS, EAC, BAC, CYCLOHEXANONE, Tetrahydrofuran, Ether, Esters, Polyimides, Dimethylformamide, Polyvinylalco
  • a water-based dye 201 such as water soluble near IR dye
  • an appropriate solvent 202 such as water or methanol
  • the water soluble near IR dye is a composition with a chemical formula of C38 H46 Cl N2 06 S2 Na; or C43 H47 N2 06 S2 Na; or C44 H52 N3 06 S3 Na; or C38 H49 N3 06 S4 Cl; C46 H51 N2 O6 S2 Cl;
  • a curved lens 503 is made wherein visible and/or IR dyed optical film 501, which is made using the present method as depicted in FIG. 3, is laminated on another clear film or glass 500, which has certain optical properties.
  • Another scratch -resistant optical glass 502 is laminated on top of the dyed functional film 501 to protect the IR/visible layer from scratches, chemicals, and/or the elements.
  • PVA water solution material is used as its own polarized layer, and/or an additional polarized layer is laminated.
  • the present application lens products reduce eye strain and increase visual comfort.
  • the Lens contains a solution casting function film or a plurality of a solution casting function film and a laminated film On Convex or (in other words) on top of the lens 0.0-1.5mm deep into the surface with or without grinding but not damaging the function film, the lens total thickness is 0.2-10.0mm, and/or with an IR thin film included or an extra 0.02-0.18mm On Convex or on top, 0.001-1.5mm deep into the surface , wherein one of the layers, with or without grinding, does not damage the function film, the lens total thickness is 0.2-10.0mm.
  • Region IR Near-IR Exposure and Cataracts one of the most common eye diseases associated with near-IR radiation is cataracts. Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Another form of damage to the eye from IR exposure includes stoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption may cause symptoms such as redness of the eye, swelling, or hemorrhaging. IR rays penetrate clouds more strongly than visible light, so its penetration rate is relatively higher, causing relatively large damage to the eyes. Cataracts caused by near-IR radiation have been noted historically in glassblowers and furnace workers. Radiation between 800 and 1,200 nm is most likely responsible for temperature increases in the lens itself because of its spectral-absorption characteristics. Visible wavelengths may also contribute to the problem since the heat absorbed by the iris could result in heat transfer to the lens.
  • Glass material for glass lenses may have a slightly anti-IR function. It takes temperatures of over 800 degrees C to melt and mix the glass with rare earth IR absorptance dye. If damaged, the dye may only absorb radiations with wavelength of 750nm, 810nm, or 890nm. Lenses may be made using injection or extrusion, but the processes may require temperatures to be over 230 degrees C, which can melt polymer plastic, damage the dye structure, and decrease color. Moreover, the lenses may need to have a thickness of at least
  • Organic IR dyes absorb 760-1100 nm of near-IR radiation ray. The function was more efficient than inorganic IR dyes. Inorganic IR dye contains haze, is a particle, and cannot be used at too high of a percentage or clarity may be deteriorated.
  • a High contrast, or enhanced contrast, functional polymer film comprised of organic dye, absorbing selective narrow band-width wavelength attenuation (Absorbed) of unwanted radiation light 570-590nm over 20%, High contrast, or enhance contrast of Functional polymer film on lens part of top side 0 - 0.7mm without grinding or semi Rx thicker optical lens with grinding but not reaching the functional film surface, total lens thickness 0.05-8.0mm.
  • Exemplary photochromic dyes include, but are not limited to, triarylmethanes, stilbenes, azastilbenes, nitrones, fulgides, spiropyrans, naphthopyrans, Spiro-oxazines, quinones and the like.
  • FIGURES 7A-Z show some example spectrometer charts using various example dye combinations. The results may be produced by the solution casting method, although it will be appreciated that other methods may be used. Unless otherwise indicated, the charts may use a Y-axis with “%T” or percent transmission of light; the X-axis may represent light wavelength in nanometers.
