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.
An apparatus for blocking light rays comprising a plurality of polarized films, each of said plurality of polarized films having polarization apertures, wherein each film has a top and bottom side, said plurality of polarized films are pliable and peelably connected to one another by a first adhesive layer positioned between said bottom side and said top side of adjacent polarized films, said plurality of polarized films are connected to a transparent medium by a second adhesive layer positioned between said bottom side of a respective one of said plurality of polarized films adjacent to said transparent medium, wherein polarization apertures have various predetermined sizes and angular orientation causing said plurality of polarized films to be polarized and each respective one of said plurality of polarized films has a unique tint level, wherein upon securing said plurality of polarized films to said transparent medium, a user can selectively determine an opacity level by selectively peeling off respective ones of said plurality of polarized films.
