    Abstract: Methods and apparatus for separating substrates are disclosed, as are articles formed from the separated substrates. A method of separating a substrate having first and second surfaces includes directing a beam of laser light to pass through the first surface and, thereafter, to pass through the second surface. The beam of laser light has a beam waist located at a surface of the substrate or outside the substrate. Relative motion between the beam of laser light and the substrate is caused to scan a spot on a surface of the substrate to be scanned along a guide path. Portions of the substrate illuminated within the spot absorb light within the beam of laser light so that the substrate can be separated along the guide path.

  • Patent number: 8651660
    Abstract: The present invention describes ophthalmic lens products comprising a multilayer wafer and an injection-molded polycarbonate inner portion. The multilayer wafer includes a dyed, photochromic or polarized layer between a tinted inner layer and an outer polymeric layer. The inner layer may be solid or gradient-tinted. The polycarbonate inner portion of the lens product is directly fused to the tinted inner layer of the multilayer wafer during injection molding. The invention further describes a method to produce a gradient-tinted polarized polycarbonate eyewear lens product by obtaining a multilayer wafer having an outer layer, an inner polycarbonate layer, and a polarized layer between the inner and outer layers, applying a gradient tint to the wafer's inner layer, placing the gradient tinted wafer within an injection-molding cavity, and injecting molten polycarbonate directly against the wafer's gradient-tinted layer to form the inner portion of the lens product and to fuse it to the wafer.

  • Publication number: 20140036227
    Abstract: A photochromic lens is proposed which can lose its color in a shorter period of time, and which is less likely to deteriorate when exposed to ultraviolet radiation. The photochromic lens is formed by dissolving 0.03 to 0.2 parts by mass of a spirooxazine photochromic compound in tetrahydrofuran, mixing the solution thus obtained into 100 parts by mass of a lens resin material so that the photochromic compound is uniformly dispersed in the resin material.
