A transparent laminate including a transparent substrate and structure layer, wherein the structure layer contains protrusion portions, depression portions, or both on a surface thereof, and an average distance between the adjacent protrusion portions or between the adjacent depression portions is equal to or less than a visible light wavelength, the structure layer includes a polymerized product of an active energy ray curable resin composition, the resin composition includes a composition of a (meth)acryloyl group-containing polymerizable compound, the compound composition includes one or more from each of (A), (B), and (C):

Transparent laminate

There is provided a novel and improved eyeglasses protection device capable of suppressing occurrence of reflected light that may enter eyes of a user of the eyeglasses protection device and thus reducing fatigue of the user, the eyeglasses protection device including: a lens surface protective part configured to protect a lens surface of eyeglasses. The lens surface protective part is equipped with a substrate film, and a micro concavo-convex structure that is formed on a surface of the substrate film, with an average period of the concavo-convex part being equal to or less than a wavelength of visible light. According to the aforementioned viewpoint of the present invention, it is possible to suppress occurrence of reflected light that may enter eyes of a user of the eyeglasses protection device because the micro concavo-convex structure is formed in the lens surface protective part of the eyeglasses protection device.

Eyeglasses protection device

There is provided a transparent film for a face protection shield in which transparency is enhanced and visibility from a non-wearer is also enhanced, the transparent film for a face protection shield including: a transparent base material having flexibility; and a transparent resin layer configured to be laminated on at least one of surfaces of the transparent base material, the transparent resin layer having on a surface a plurality of structural bodies including concavities or convexities provided at a pitch of less than or equal to a visible light wavelength. A refractive index of the transparent base material is different from a refractive index of the transparent resin layer, and an interface between the transparent base material and the transparent resin layer has a concave-convex shape.

Transparent film for face protection shield

An optical element is provided which reflects a reduced amount of light even under a very high intensity lighting system used for a surgical operation, a dental treatment etc., has anti-fogging performance, and is transparent and useful for face protection. The optical element has a flexible transparent substrate and a plurality of structures disposed on opposite surfaces of the substrate at a pitch equal to or less than the wavelength of visible light. The structures are formed from a cured product of a resin having a hydrophilic functional group.

Face protective optical element

The purpose of the present invention is to prevent an increase in reflectance and a decrease in transmittance, retain the intact instantaneousness and ease of stripping, improve the releasability of the adhesive, avoid the generation of distortion due to the thickness of the adhesive, and ensure the visibility, by laminating filmy members () each equipped with a moth-eye structure (). This transparent laminate () comprises a plurality of filmy members () which each comprise a base () and, disposed on at least one surface thereof, a structure () made up of recesses and protrusions which have been regularly arranged at a pitch not longer than the wavelengths of visible light. At least the ends of the filmy members () have been superposed, with a pressure-sensitive adhesive layer () interposed therebetween. In the superposed filmy members (), there is a space () between the opposed structures ().
