Polarization by the use of a polarized filter. The most common method of polarization involves the use of a polarized filter, polarized filters and made of special material that is capable of blocking the horizontal plane of vibration of the electric magnetic Lightwave. This elimination of the horizontal vibrating particles of light enables a greater clarity of light distributed on the retina without distortion. A polarized surface serves as a device that filters out one half of the vibrations upon the transmission of the light through a filter. When unpolarized light is transmitted through a polarized filter, it emerges with half the intensity and without the horizontal distortion. This is most evident in polarized filters for camera equipment and lens fittings.
Any Polaroid filter is able to polarize last, because of the chemical composition of the filter material itself. The filters material structure is formed with molecules that are aligned within the filter in the same direction. During the fabrication of the filter, the molecules are stretched across the filter, so that each molecule is a lawn in a vertical direction. As unpolarized light strikes the filter, the portion of waves vibrating in the vertical direction are allowed to pass through undistorted providing a clarity of image beyond our natural biological filter this filters that are used to look through And view objects in design, like glazing or other transparent materials. The filters do not distort the shape or dimension of the landscape. It is effectively a dimmer lighting switch, since one half of the light is blocked, as it passes through the filter in question.
In theory, I pair of filters placed back to back with one filter in a vertical axis and one in a horizontal axis will effectively block out both angles of electric magnetic Lightwave therefore blocking the viewers image altogether.
