A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low ...
Polarizing sheets are used in liquid-crystal displays, optical microscopes and sunglasses.Since Polaroid sheet is dichroic, it will absorb impinging light of one plane of polarization, so sunglasses will reduce the partially polarized light reflected from level surfaces such as windows and sheets of water, for example.
However, this crystal is seldom used as a polarizer, since the dichroic effect is strongly wavelength dependent and the crystal appears coloured. Herapathite is also dichroic, and is not strongly coloured, but is difficult to grow in large crystals. A Polaroid polarizing filter functions similarly on an atomic scale to the wire-grid polarizer ...
The third and fourth Purkinje images can be visible from within the eye itself. Light reflected away from the surfaces of the lens can in turn reflect back into the eye from the rear surface of the cornea. The first and fourth Purkinje images are used by some eye trackers, devices to measure the position of
Images with greater salience allow for an optimal use of a cyclopean image, as important details can be extracted. In other words, an image of higher quality has more meaning to the eye. Although it has limitations due to the surroundings, cyclopean images can be very adaptive. [9]

Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. ' silver-rock ' ) and also called optical calcite , is a transparent variety of calcite , or crystallized calcium carbonate , originally brought from Iceland , and used in demonstrating the polarization of light .
