The present invention 10 discloses a polarized filter film having a plurality of light-filtering layers 20, 22, 24, each having a different polarization aperture and tint hue that can be selectively combined to form a polarized filter film having a combined opacity rating of 5% to 55% when applied to a transparent medium 18 such as a window. The combined polarized filter film 10 is comprised of a plurality of layers 20, 22, 24 of light-filtering material wherein each layer has a plurality of apertures 26, 28 positioned either vertically 36 or angularly 38 so that the horizontal rays associated with glare are reduced dramatically. Each layer of film has a plurality of slotted apertures 36, 38 that is biased or offset from the overlaying light-filtering film apertures whereby varying degrees of light-blocking properties can be achieved by using the light-filtering films in conjunction with additional layers. The present invention 10 is attached to the transparent medium 18 by using an adhesive 30 which has a removable protective backing layer 34.
