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.

First claim

6. The eyeglasses protection device according to claim 2 ,
wherein the one or the plurality of auxiliary cut holes extend from outer edges of the insertion holes toward outside of the insertion holes, and
wherein the attachment parts are equipped with auxiliary holding parts formed by the auxiliary cut holes in circumferences of the insertion holes.

7. The eyeglasses protection device according to claim 6 ,
wherein the one or the plurality of auxiliary cut holes of one insertion hole of the plurality of insertion holes are entirely separated from other insertion holes of the plurality of insertion holes by the substrate film.

8. The eyeglasses protection device according to claim 1 ,
wherein the micro concavo-convex structure is formed of a hardened ultraviolet curable resin.

9. The eyeglasses protection device according to claim 1 ,
wherein the micro concavo-convex structure comprises a compound that includes a hydrophilic functional group.

10. The eyeglasses protection device according to claim 1 ,
wherein an in-plane retardation value of the lens surface protective part is equal to or less than 100 nm with respect to a wavelength of visible light, and
wherein the substrate film is made of a non-stretched film.

11. An eyeglasses protection device laminated article in which the eyeglasses protection device according to claim 1 is laminated.

12. The eyeglasses protection device according to claim 1 ,
wherein the one or the plurality of auxiliary cut holes extend in a direction perpendicular to a length of the insertion holes.

13. The eyeglasses protection device according to claim 1 , wherein the one or the plurality of auxiliary cut holes extend, from outer edges of adjacent insertion holes of the plurality of insertion holes of one temple protective part of the plurality of temple protective parts, toward outside of the adjacent insertion holes of the one temple protective part, and
wherein the one or the plurality of auxiliary cut holes extend, from inner edges of adjacent insertion holes of the plurality of insertion holes of another temple protective part of the plurality of temple protective parts, toward inside of the adjacent insertion holes of the another temple protective part.

14. An eyeglasses protection device comprising:
a lens surface protective part configured to protect a lens surface of eyeglasses having two ends in a length direction; and
a plurality of temple protective parts that are formed at both ends of the lens surface protective part in the length direction and protect temples of the eyeglasses,
wherein the temple protective parts are equipped with attachment parts equipped with a plurality of insertion holes at which the eyeglasses protection device is configured to be attached to the temples of the eyeglasses,
