OPTICAL FILM, AND OPTICAL LAMINATE AND EYEWEAR HAVING THIS

An object of the present invention is to provide an eyewear such as polarized sunglasses using an optical film including a light reflective layer and a polarizing element layer, the eyewear having a metallic color tone conforming to signal visibility standards of various countries, and an optical film and an optical laminate for the eyewear. The present invention provides an optical film obtained by laminating a light reflective layer and a polarizing element layer, in which the optical film satisfies one or more of the following (a) to (d):(a) a central reflection wavelength of the light reflective layer is 600 nm or more and less than 660 nm, and a transmission hue of the optical film is within a region of -15 ≤ a* ≤ 10 and -20 ≤ b* ≤ 20,(b) a central reflection wavelength of the light reflective layer is 500 nm or more and less than 600 nm, and a transmission hue of the optical film is within a region of -5 ≤ a* ≤ 20 and -20 ≤ b* ≤ 30,(c) a central reflection wavelength of the light reflective layer is 660 nm or more and less than 750 nm, and a transmission hue of the optical film is within a region of -10 ≤ a* ≤ 10 and -5 ≤ b* ≤ 35, and(d) a central reflection wavelength of the light reflective layer is 400 nm or more and less than 500 nm, a minimum transmittance of the light reflective layer at 400 nm or more and less than 500 nm is 15% or more, and a transmission hue of the optical film is within a region of -15 ≤ a* ≤ 25 and -10 ≤ b* ≤ 40.
