Estimating the term…
[Problem] The present invention provides eyewear, such as polarized sunglasses, having cholesteric liquid crystal layers, wherein the eyewear has a metallic tone and antiglare properties, minimizes the reduction in light-polarizing element absorptive capability that is associated with circular polarization, and is moreover unaffected by external degrading factors such as sebum, moisture, and salt air. [Solution] This optical film is characterized by being provided with a light-reflecting layer R comprising a cholesteric liquid crystal layer that has right-handed helical orientation, a light-reflecting layer L comprising a cholesteric liquid crystal layer that has left-handed helical orientation, and a polarizing element layer.
An optical film, comprising:
An optical laminate, comprising a light-reflecting layer R comprising a cholesteric liquid crystal layer having a right-handed helical orientation, a light-reflecting layer L comprising a cholesteric liquid crystal layer having a left-handed helical orientation, and a polarizing element layer provided between a first support and a second support,
