Polarization Effect of Cheap Fake Ray Bans
Light waves from the sun and other artificial sources, such as light bulbs are vibrating and propagating in all directions. Whether light is transmitted, reflected, diffused, or refracted, when light is vibrating in one or more directions, we say that the light is polarized. Polarization fake Oakley sunglasses can be either naturally or artificially. The glare you see every time at the lake is a natural example of polarization. The glare reflected from the lake is the light that fails to filter through the lake’s “water filter”, which is why we can’t see objects under the lake no matter how clear it is.
Polarizing filters outlet Ray Ban are usually made by coating a layer of chemical film on a transparent plastic on the glass surface. Usually, the molecules in the compounds are arranged in parallel. When they are uniformly applied to the lenses, these molecules form tiny lenses that absorb all the lights in the same direction.
Most of the glare that forces you to wear cheap Oakley sunglasses comes from horizontal surfaces, such as water surfaces and highways. When light reaches a surface, the reflected light is polarized in the same direction as the surface. Thus, a horizontal surface with high reflectivity, such as the lake surface can produce a large amount of horizontal polarized lights. Therefore, the polarizing lenses of sunglasses are fixed at an angle so that only vertical polarized light can penetrate the lenses. You can observe in the following way: wear a pair of polarized high quality fake Ray Bans, and then observe a horizontal surface, tilt your head to the left or the right slowly. You will see the glare from this surface will become brighter as you adjust the angle.
Before buying, you can identify the authenticity by doing a simple test. Find a reflector, then hold sunglasses and observe the surface with a lens. Slowly rotate the sunglasses ninety degrees to see if the glare is reduced or increased. If the sunglasses are polarized sunglasses, you will see a significant decrease in glare.

There is a kind of prescription glasses who can change the color when exposed to sunlight; glasses are called color changing glasses. The color glasses were developed by Corning Company in the late 60s of last century and were popularized by Transitions Company in the 1990s. The principle of photochromic lenses relies mainly on a special chemical reaction of ultraviolet light.
Color changing best fake Ray Bans glasses contain millions of molecules of certain substances (e.g., silver chloride or silver halides). When there is no ultraviolet light, visible light can penetrate these molecules, and visible light is a common component of artificial light sources. But when exposed to ultraviolet light of the sun, these molecules will pass through a chemical process changes their shape. The new molecular structure will absorb some of the visible light and darkens the lenses. The number of molecules that change in shape varies with the intensity of ultraviolet radiation.
When you come into the room without the ultraviolet radiation, the corresponding chemical inversion will occur. When they suddenly leave the ultraviolet light, these molecules will quickly revert to the original structure, thereby losing the function of light absorption. The whole process takes place very quickly no matter it is positive or reverse.
In the Photo Brown and Photo Grey series produced by Corning Company in the 60s of last century, the lenses were made of glass, and the molecules were uniformly distributed throughout the lens. When using this method in cheap Ray Bans UK prescription glasses, the problem becomes apparent because the thickness of the different parts of the prescription lens may vary, and the color will appear darker in slightly thicker areas. However, with the increasing popularity of plastic lenses, people have developed a new method. By immersing the plastic lenses cheap fake Ray Bans in a chemical bath, the color-change molecules are absorbed into the plastic lens about 150 microns in depth. This new method is much better than a simple coating process. Among these coating techniques, the color change molecule is only 5 microns thick; therefore, there are no enough molecules available to darken the lens. At present, Transitions, a leader in photochromic lens manufacturing, has popularized the plastic lens absorption process.
