Eyewear lens creation using additive techniques with diffuse light
Systems and methods for lens creations are disclosed. The method includes initiating light transmission from a light source through a diffuser into a container holding resin and a substrate. The light transmission is performed according to an irradiation pattern wherein each point in the resin is illuminated by at least 10% of the diffuser. This causes a lens to be formed. To achieve this illumination, at least 15% of the diffuser receives light from the light source. Further, a diameter of the diffuser is greater than or equal to a diameter of the substrate. The system performing the methods includes a polymerization apparatus and may include a resin conditioning and reservoir apparatus, a metrology unit, a resin drainage apparatus and an optional postcuring apparatus.
Eyeglass lens material and eyeglass lens capable of blocking blue light and method for making the same
An eyeglass lens material can be used to make an eyeglass lens and at least includes a mixture of Ag/SiO.sub.x composite nanoparticles and at least one type of monomer. The eyeglass lens is capable of blocking blue light. The monomer undergoes a material curing procedure to form a main body that contains and is mixed with the Ag/SiO.sub.x composite nanoparticles. As the Ag/SiO.sub.x composite nanoparticles in the eyeglass lens material can absorb relatively high-energy blue light, a contact lens made of the eyeglass lens material can block blue light.
METHOD OF PRODUCING A LENS WITH AN EMBEDDED FOIL
A method of producing a lens with an embedded foil, comprising the steps of positioning a foil (10) on a foil fixation holder, providing adhesive attachment dots (41) on the foil (10) on surface portions (12) opposite to the foil fixation holder, positioning the front mould (30) ensuring the contact of the attachment dots (41) with a surface (31) of the front mould (30), retracting the foil fixation holder and positioning a back mould (120) opposite to the front mould (30). Then the front mould (30) and the rear mould (120) are connected with a sealing bridging element (90) to build an assembly in order to form a mould cavity (45, 155) with a pouring opening, wherein the edge (11) of the foil (10) is spaced apart (112) from the bridging element (90) and the assembly comprises passages between the attachment dots (141), the foil (10) and the front mould backside (31) allowing pouring a monomer into the entire mould cavity (45, 155) before curing the monomer and decomposing the assembly as well as cutting the lens with the embedded foil from the polymer block.

HIGH PRECISION NANOSCALE THIN FILM FABRICATION PROCESSES
A method for fabricating one or more elements in a multi-lens column. Drops of ultraviolet (UV)-curable liquid are dispensed by an inkjet on a substrate, which may be supported by a chuck. A non-uniform liquid film is then formed, such as by spreading and merging of the inkjetted drops. The film is then locally heated, such as by using a digital micromirror device array. The film is then cured by exposing it to UV light, where the cured film together with the substrate form an element of the multi-lens column. The substrate is then brought to a metrology station where optical metrology is performed on the cured film and the substrate for quality control.
Systems, articles, and methods for integrating holographic optical elements with eyeglass lenses
Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer file to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lends around the photopolymer film; sandwiching photopolymer film in between two portions of a lens' applying photopolymer film to a concave surface of a lens' and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.
