All black sunglasses giving a more different feeling, coupled with a British student faction of the shirt for you to create the most popular style. Different styles of sunglasses of course require different styles of jackets come with matching; current popular short coat is a good choice. Down the bright side, of course, also need coupled with a pair of stylish Tiffany and Co Charm Bracelet Jewelry Outlet sunglasses, regardless of the length of money would be a positive choice. Handsome full sense of the sunglasses of course, require a handsome coat correspondingly, the military section of the jacket is a positive choice. Injury if subjected to strong ultraviolet content, prolonged exposure to the sun. Increase the risk of cataracts. When selecting sunglasses, is considered to be over its ultraviolet function, over the more powerful faction, the better the protection. Many people think. Lens rather avoid the deeper the color the sun stimulate actual fact.
Lens along the deeper color, wear cut the pupil is enlarged, so if there is no outside filtering Ying, the right eye damage tolerance will be greater. Lenses currently used on car windows, Tiffany and Co Necklace Jewelry Outlet Store sunglasses, and visual display components, and its basic composition is halogen material. Japanese researchers have developed a sense of light can be recycled lenses; this will destroy the environment without halogen material within this new ecological lens components. Photographic negatives like, now light lenses darken sense because silver and halogen-containing compounds within the lens, such as silver iodide. Too little sun's ultraviolet rays to provide sufficient energy electrons do move containing halogen ions, these electrons combine with silver ions to metallic silver to become neutral atoms.
However, this process is reversible, after some Fake Oakleys Frogskins Sunglasses Cheap for Sale sunglasses away from ultraviolet radiation will restore transparency within minutes, while others have just been through a heating process of restitution. In each of the response process, the electron released from the silver atoms, resulting in clusters of the metal into the silver ions again. Toxic and carcinogenic compounds generated by halogen and carbon-based molecules will react, in order to replace halogen, Tetsuo Osaka, Japan Industrial Technology Research Institute, and colleagues of the silver ions in the form of silver nitrate added to complete mixed standard lens material. Refers specifically to withstand the harsh things the device, to prevent his glasses were blinded.
Silver nitrate lenses made from transparent to UV light will turn yellow, will revert to transparent. This lens is made of a transparent yellow color change but recovery can be repeated numerous times. For certain applications the surface, the broader the spectrum is required, then the researcher is currently unable to develop further into other color Cheap Mac Cosmetics Makeup wholesale Outlet lenses, while discoloration is by far the results of all the ultraviolet laser irradiation after a few minutes, rather than natural light through. However, this new material has outstanding change in the display process, the halogen is not necessary. The study also pointed out that the development of this new material could help more high-tech applications of laser optical memory element can be repeated through the information printed on the optical memory element.
