A lens assembly includes a tube in which optical elements such as lenses or micro-lenses are individually fabricated by dispensing a volume of curable optical polymer into the tube, forming the desired shape for the optical element using one or more plungers having heads corresponding to a desired lensing curvature, applying radiant energy to the tube with the plungers in place to cure the optical polymer, and repeating as needed until the desired number of optical elements are fabricated within the lens assembly which may then be integrated as a single piece into a mobile or wearable device.

In the embodiments, an aqueous hydrochloric acid solution instead of hydrogen chloride gas and solid triphosgene instead of phosgene gas may be used in the process of preparing a diisocyanate from a diamine through a diamine hydrochloride. In addition, the embodiments provide processes for preparing a diisocyanate composition and an optical lens of higher quality, in which the reaction temperature of a diamine hydrochloride composition and triphosgene is controlled to a specific range, or a crude diisocyanate composition obtained from the reaction of a diamine hydrochloride composition and triphosgene is distilled at a specific temperature range, or the molar ratio of a diamine hydrochloride and triphosgene is adjusted to a specific range.

Systems and methods for lighting system lens heating are described. The systems and methods include a substantially clear thermoplastic substrate; and a conductive ink or film circuit on the thermoplastic substrate.

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 he 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.

The present disclosure relates to a machine for an automated filling of a mold assembly for molding an ophthalmic lens, comprising: filling means to fill the mold assembly with a molding material through a filling aperture provided in the mold assembly, acquiring means to acquire an input value linked to the internal volume of the mold assembly, and control means for controlling the flow rate of molding material injected by the filling means in the mold assembly according to a flow rate profile deduced as a function of said input value.

Provided herein are methods of molding thermoplastic polymers into optical elements. The optical elements in the form of cylindrical discs, semi-finished lens blanks or finished lenses are compression molded at high temperature typically above thermoplastic polymers softening temperature and under high pressure. The semi-finished lens blanks and finished lenses are molded using front and back glass molds inside a mold assembly which reshapes the cylindrical discs that are either previously molded or cut out from thick slab. Also provided are methods for producing single vision and progressive addition lens prescriptions.

The plastic polarizing lens of the present invention includes a polarizing film comprised of a thermoplastic resin; a first resin substrate composed of at least one layer stacked over a surface of the polarizing film which is located on an object-facing surface side; and a second resin substrate composed of at least one layer stacked over a surface of the polarizing film which is located on an eye-facing surface side, in which an organic colorant compound is included in at least one layer constituting the first resin substrate out of the first resin substrate and the second resin substrate, and the concentration of the organic colorant compound in the first resin substrate is higher than the concentration of the organic colorant compound in the second resin substrate.

A polarizing film having a molded shape, in which a difference in average transmittance of the polarizing film at a wavelength of 400 to 700 nm is 5% or less before and after molding the shape of the polarizing film. In addition, when molding the polarizing film into a shape such as a curved surface, the polarizing film is heat-treated in a temperature range of Tg20 C. or higher and Tg+10 C. or lower, where Tg is a glass transition point of a resin constituting the polarizing film. Further, one chamber is divided into a first space and a second space by the polarizing film disposed in the chamber, and the polarizing film is transfer-molded along a molding surface by a differential pressure generated by making a pressure in the first space and a pressure in the second space different from each other.

A method is for manufacturing a structure obtained by stacking a substrate that is a first member as a base material, and lens arrays that are second members that are opposed to the substrate, are formed of a resin material different from the substrate, and have a shape on a surface. The method includes a surface activation step of performing an activation treatment to cause an activation state of at least one of a surface of the substrate or a surface of the lens arrays, and a bonding step of pressurizing the lens arrays at least at a temperature that is equal to or higher than a reference temperature obtained by subtracting 30 C. from a load deflection temperature of a resin material of the lens arrays, and is equal to or lower than a glass transition temperature, to closely bond to the substrate.

A method of manufacturing a plastic lens includes: a step of putting a first curable composition over a forming surface of a first mold substrate having the forming surface for forming a lens surface; a step of spreading the first curable composition over the entire forming surface by pressing the composition with a film to form a first curable composition layer and separating the film from the first mold substrate by a predetermined distance through the formed first curable composition layer; a step of covering defined surfaces; a step of injecting a second curable composition into a defined location; a step of curing the first curable composition layer and the injected second curable composition; and a step of removing to obtain a plastic lens.
