Zusammenfassung: | The purpose of the present invention is to provide: goggles such as polarized sunglasses using an optical film having a light reflecting layer and a polarizing element layer; goggles having a metallic color tone and conforming to the signal recognition standards of various countries; and an optical film and an optical laminate for use in the goggles. Provided is an optical film in which a light reflecting layer and a polarizing element layer are laminated, said optical film satisfying at least one of the following (a) to (d). (a) The center reflection wavelength of the light reflecting layer is 600 nm or more and less than 660 nm, and the transmission hue of the optical film is within the range of-15 < = a * < = 10 and-20 < = b * < = 20. (b) The center reflection wavelength of the light reflecting layer is 500 nm or more and less than 600 nm, and the transmission hue of the optical film is within the region of-5 < = a * < = 20 and-20 < = b * < = 30. (c) The center reflection wavelength of the light reflecting |
