20100283957 | POLARIZED EYEWEAR - An article of polarized eyewear has a lens, with a first substrate lens material transparent to visible light and a pattern of elongated structures formed from at least a second material having a complex index of refraction, wherein the second material is deposited directly onto a curved surface of the first substrate lens material. A pitch between adjacent elongated structures is less than 300 nm and a width of each elongated structure is less than 90% of the pitch. A photochromic material is deposited onto the polarized eyewear. | 11-11-2010 |
20110001921 | EYEWEAR DEVICE AND METHOD OF MAKING THE SAME - An eyewear device can include a frame including an eyewire and a ledge, the eyewire at least partially encircling a lens and the at least one lens resting on the ledge, and a plurality of chamber walls in the ledge between the at least one lens and the frame, wherein the plurality of chamber walls are configured to allow air to circulate between opposite sides of the lens to reduce fogging. A method of producing an eyewear device can include providing a frame comprising an eyewire and a ledge, the eyewire at least partially encircling a lens and the at least one lens resting on the ledge, and providing a plurality of grooves in the ledge between the at least one lens and the frame, wherein the plurality of grooves are configured to allow air to circulate between opposite sides of the lens to reduce fogging. | 01-06-2011 |
20120013981 | PHOTOCHROMIC OPTICAL ELEMENTS - An optical element has a substrate material having a pattern of cavities formed on a surface and a substantially transparent seal layer disposed against the surface. A photochromic or electrochromic material is sealed by the substantially transparent seal layer within the cavities formed in the surface. | 01-19-2012 |
20140029096 | 3D Polarized Eyewear - An article of eyewear for viewing a 3D display has at least one lens, wherein the at least one lens has a substrate lens material that is transparent to visible light and has a curved surface. A circular polarizer is formed on the substrate lens material and has a linear polarizer with a polarization axis and a quarter wave plate with a retardation axis that is inclined at substantially 45 degrees from the polarization axis along the curved surface. Either or both of the linear polarizer and the quarter wave plate are formed as sub-wavelength elongated structure devices. | 01-30-2014 |
