An assembly sticking device includes an absorbing device for absorbing a plurality of optical sheets, and a transmission device arranged below the absorbing device for horizontally transporting the curved backlight module to be assembled with the optical sheets. When the transmission device horizontally transmits one of the curved backlight modules to be right below the absorbing device, the absorbing device configures one optical sheet to face toward the curved backlight module, the absorbing device moves close to the transmission device, and releases the optical sheets such that the released optical sheets is assembled with the curved backlight module.

Method and composition for switchable panels are disclosed. Switchable films are placed between glass and liquid resin is injected between the glass and cured. The panels may be used for a wide variety of applications.

Curved lenses and methods for making curved lenses are described. One embodiment of a method of making a curved lens includes curving a lens blank made of a linear polarizer layer laminated together with a plurality of polymeric layers. The lens blank is curved by heating and pressing the lens blank between a curved rigid member and a flexible member at a pressure and maintaining the pressure for a time sufficient to allow the lens blank to conform to the shape of the curved rigid member. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.

An LED light fixture includes a heat-sink, a circuit board thereon with a plurality of spaced LED light sources, and a one-piece optical member with a plurality of secondary lenses over corresponding LED light sources and having a lens flange surrounding the lenses and integral with each lens. The optical member includes a polymeric carrier portion surrounding the lenses, overlapping with and molded onto the lens flanges across such overlapping, and extending therefrom to a peripheral edge portion. The optical member has an outer surface infused with an ultraviolet inhibitor to increase long-term weathering performance. The infused outer surface includes an outer layer of each lens and extends to form an outer layer of the lens flanges and therebeyond to form an outer layer of the carrier portion. The invention also includes a method of manufacturing such infused optical member.

An object of the present invention is to provide a thin and lightweight polarizing lens for use in lightweight sunglasses (in particular, rimless sunglasses) while maintaining the clamping force and mechanical strength of a temple part, and a manufacturing method therefor. The values of: the center thickness v of a polarizing lens A including an injection-molded layer 3 laminated on at least one surface of a polarizing sheet B, the injection-molded layer having a polyamide-based resin; and the flexural modulus of the injection-molded layer 3 are adjusted, thus the predetermined clamping force and mechanical strength of a temple part are obtained even in the case of sunglasses with the thin and lightweight polarizing lens.

A method of manufacture of an optical element for focusing electromagnetic radiation, comprising the steps of:•(a) providing a first light-transmissive glass substrate (20) having a front surface on which the electromagnetic radiation is incident in use and a back surface opposite to the front surface;•(b) applying a liquid silicone resin (30) to the back and/or the front surface of the glass substrate;•(c) contacting the liquid silicone resin with a mould such that the liquid silicone resin adopts the form of the mould and forms microstructures extending over the surface(s) of the glass substrate to which the liquid silicone resin has been applied;•(d) curing the liquid silicone resin to form a microstructured light-transmissive silicone coating wherein the glass surface has been
