The core of the Polarized polarizing film having a diachronic polarizing transparent film which allows transmission axis parallel to the direction of vibration by means of the light, the direction perpendicular to the light were absorbed, a phenomenon called the polarization technology. The light through the same vibration direction of the light is called polarized light. Because the reflected light is reflected light through a transmission axis of the polarizing film is absorbed perpendicular. Polarized is the use of this principle very effectively eliminates the strong reflections and stray light so that the light becomes soft, so that people can see clearly the natural scenery. Cheap Oakleys Frogskins Sunglasses Sale Polarized can effectively absorb both UVA and UVB, good eye protection. But not Polarized lens through buying Polarized, there will be a test piece, there are some pictures, just bring Polarized can be seen. In fact, this is a special test piece, the principle is the use of polarized light to see inside the Polarized parallel light emitted picture, so you see the pictures hidden on the inside, and not the perspective, this is only testing is not really Polarized approach.
Polarized sunglasses are affixed to the lens clear polarized lens material electrostatic standard, or in the product are marked on the tag using polarized lenses. In the purchase of polarized sunglasses, you can use polarizing test piece for testing. On the part of the pattern of the test piece does not recognize with the naked eye, but can be clearly identified through polarized lenses. According to the LCD display principle, observed by polarized lenses such as mobile phones LCD screen, rotate the screen, the screen will go blank as the rotation is because Polaroid filter the light of the screen caused by a single direction. Commonly known as the PC is bulletproof glass, lens material adhering to the excellent characteristics of super impact resistance, impact strength is as high as ordinary resin. PC lens itself is already very hard lenses, and do not need to add hardware. PC tablets, also known as space film, the universe films, chemical called poly carbon acid resin, a thermoplastic material. The raw material for the liquid, shaping of the lens by heating, so this will be finished lenses after excessive heat deformation, not suitable for high heat applications.
PC lens has a strong toughness, not broken, so called safety glasses. Proportion of only two grams per cubic centimeter, is currently the lightest Tiffany and Co Bracelet Jewelry Outlet lens material used. PC lens manufacturer Sailor global devaluation, its advantage is reflected in the handling and processing hard spherical lens processing. Benefits of PC lens PC space lenses are made of polycarbonate lenses, and common resin lens is essentially the difference. Commonly known the PC is bulletproof glass, so PC lens material adhering to the excellent characteristics of super- impact force, and because of high refractive index and light weight, greatly reducing the weight of the lens. If in the process, there is no problem, lighter weight than ordinary resin sheet; high impact strength is ordinary resin. Its lightweight impact-resistant properties, making it the first choice for sports sunglasses lens material. TR-90 is a kind of memory polymer material, is currently the most popular ultra-light frame material with super toughness, crashworthiness wear, low coefficient of friction, can effectively prevent the movement, due to frame fracture and friction on the eyes and facial damage. Its specific molecular structure, good chemical resistance, high temperature environment is not easy deformation, can be high temperature short time, not melting and burning.
We are in daily use glasses in the process, often find the lens very easily scratched or worn, and wear down the lens due to its transparency, refractive errors, not only will lead to blurred vision and distortion, but also feel strenuous, so eyes long-running tensions uncoordinated, visual clutter of the state and causing poor vision correction illusion. If young people, long-term use lens wear glasses, the eyes will cause more damage. In fact most of the spectacle lens wear are wipe clean lenses produced. Early glasses of glass lenses, because wear, we do not care about wiping and cleaning methods, we can say what is on what hand rub. With the popularity of resin Cheap North Face Denali Jackets Sale lenses, heavy glass lens been eliminated, but wipe the glass lens approach has not changed. Resin lenses must not be dry rub, rinse with fresh water after dry naturally, if oil, after washing with a mild detergent to eliminate. Such cleaning glasses is good but is not convenient, the need for water, and drying time is longer, it will leave a lot of water damage. Especially after meals and students during the school such conditions were not the case, free hand or other items such as a clean cloth to wipe the lens will inevitably lead to wear and tear, dirt left on the lens for a long time, will lead to resin spectacle lenses on the ferry film off, causing further damage to the lens.
