An optical product according to the present invention includes a transparent base material, and a multilayer film including a dielectric film and an ITO film. The multilayer film is formed on one face or two faces of the transparent base material. The physical thickness of the ITO film is not less than 3 nanometers and not greater than 7 nanometers. The ITO film can be formed by vapor deposition with plasma treatment.

Optical product and method for manufacturing same

A display unit includes an image data output device, an image projecting device that projects image data so as to be perceived by eyes of a user, a skeleton frame on which the image projecting device is mounted, the sunglass lenses being disposed on the skeleton frame, in which the sunglass lenses are set so that a transmissivity of visible light in a predetermined wavelength region is peculiarly low and so that transmissivities of visible light in wavelength regions other than the visible light in the predetermined wavelength region are peculiarly high, and in which the coloring of image light visualized by the image projecting device is formed by light differing in color from the visible light having peculiarly high transmissivities in the sunglass lenses.
