Abstract: 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.

Abstract: 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.
Abstract translation: 本发明提供一种能够抑制可能进入眼镜保护装置的使用者的眼睛的反射光的发生，从而减轻使用者的疲劳的新型改进的眼镜保护装置，该眼镜保护装置包括：透镜面保护部件， 保护眼镜镜片表面。 透镜表面保护部件配备有基板膜和形成在基板膜的表面上的微凹凸结构，凹凸部的平均周期等于或小于可见光的波长 光。 根据本发明的上述观点，由于微型凹凸结构形成在眼镜保护部的镜片表面保护部中，所以能够抑制可能进入眼镜保护装置的使用者的眼睛的反射光的发生 设备。
