Polarization by reflection. In design we can manipulate on polarized light to form polarization by reflection of non metallic surfaces. The extent to which polarization occurs is dependent upon the angle at which the light or artificial light approaches the surface, and the type of selected material for that surface. Metallic surfaces reflect light waves with a variety of vibrational directions, increasing the value of contrasting electromagnetic light angles, making the unpolarized light worse. However, non metallic surfaces such as flat matte concrete panels and other matte finished surfaces reflect lots That there is a large concentration of vibrations in a plane parallel to the reflecting surface. A person viewing objects by means of light reflected off a non metallic surface will however, often perceive some glare, if the extent of polarization is too much.

This is best explained when light reflected off a lake or still body of water is particularly polarized in a direction parallel to the water surface. This is an indication of the importance when selecting finishing materials, or the type and light distributed across the design surface.
