The invention provides an optical film and a pair of polarized sun glasses. The optical film can be easy to produce reliably with enough thickness and does not damage the optical function of the other optical films even being stacked on the other optical films, and is suitable for the polarized plate with certain thickness, such as the polarized sun glasses. The optical film is made by extrusion molding method with width of 100mu to 500mu, visible ray transmissivity of more than 87%, haze of less than 2%, phase different at plane direction of less than 200nm, and phase different at thickness direction of less than 400nm. Therefore, the invention can make the lens having enough thickness without damaging the optical function of the polarized sun glasses when being applied to the lens of the polarized sun glasses. |
