Clean the sunglasses regularly using sunglasses cleaning products like a microfiber cloth, or a sun glass cleaner. Avoid leaving your sunglasses in extreme heat or cold, like a car. Don't touch the lenses of the sunglasses, the oils on your hands can cause damage. Use a protective case for your sunglasses.
Thus reflected light from horizontal surfaces (such as the surface of a road) at a distance much greater than one's height (so that the incidence angle of specularly reflected light is near, or usually well beyond the Brewster angle) is strongly s-polarized. Polarized sunglasses use a sheet of polarizing material to block horizontally-polarized ...
Mirrored coatings can be made any color by the manufacturer for styling and fashion purposes. The color of the mirrored surface is irrelevant to the color of the lens. For example, a gray lens can have a blue mirror coating, and a brown lens can have a silver coating. Sunglasses of this type are sometimes called mirrorshades. A mirror coating ...
This means that a pair of aligned DLP projectors, some polarizing filters, a silver screen, and a computer with a dual-head graphics card can be used to form a relatively high-cost (over US$10,000 in 2010) system for displaying stereoscopic 3D data simultaneously to a group of people wearing polarized glasses.
Certain crystals, due to the effects described by crystal optics, show dichroism, preferential absorption of light which is polarized in particular directions. They can therefore be used as linear polarizers. The best known crystal of this type is tourmaline. However, this crystal is seldom used as a polarizer, since the dichroic effect is ...
Target: You can always count on Target to bring the deals, including up to 40% off floor care, up to 45% off headphones and 50% off board games for the perfect New Year's Eve night in.
The lenses of smart sunglasses can be manufactured out of multiple adaptive cells, therefore different parts of the lens can exhibit different optical properties. For example, the top of the lens can be electronically configured to have different polarization filter characteristics and different opacity than the lower part of the lens.
Silly string is often used in a celebratory fashion, but it can quickly cause a big mess. In the city of Meriden, silly string cannot be sold to minors unless they are with a parent or legal guardian.
