Polarized sunglasses lenses can darken in the sun rays to shoot after. After lighting weakened, it also becomes brighter again. It does so because the silver halide crystals at work. Under normal circumstances, it can maintain a perfect lens transparency. Under sunlight irradiation, crystal silver will be separated; in free form in the Fake Oakleys Frogskins Sunglasses Cheap for Sale lens inside the silver they form small aggregates. These small gathering takes the shape of interlocking silver irregular lumps, they can not transmit light, but can only absorb light, the result makes the lenses darken. In the case of light and dark, heavy crystal formation, the lens has to return to the bright state.
Color saturation, so that the object contours become blurred, make eye fatigue, discomfort. Polaroid is made based on the principle of light polarization, when the plane of vibration and light polarization axis that is parallel to the polarization filter through. Thus, the light is organized into the same direction of light into the eye, so that the surrounding scenery looks clear without glare. Another advantage is the film plus very light, very thin and impact resistance, so this lens is ideal for driving and outdoor activities to wear in recent years, favored by the majority. Driving are more like to wear polarized sunglasses, because in addition to blocking UV polarizer, but also to minimize glare and filter out reflected glare. For example, while driving across the car bright lights, or driving in the car in front of the rear window stickers reflective barrier due to strong UV glare of the sun window film is formed, so that the wearer can clearly see the front of the thing.
General sunglasses just use dimmer role because generally can not filter the light lenses, we can only reduce the intensity of glare, UV, etc., and can not completely block these harmful rays, so its function is to reduce damage to the eyes, but in general the sun the biggest advantage is the epidemic Tiffany and Co Heart Necklace Jewelry Outlet glasses good. Polarized lenses with polarized due to the nature of, so I can completely block the dazzling glare scattering due to various factors, inflection, etc. caused by the reflection. Can also harmful to the human eye completely block UV light, bright people in the long-term activity, eye fatigue is not easy to achieve real protection function, and let see things more clearly, three-dimensional. Plane of the vibration direction of linear polarization component of the propagation direction is called the plane of vibration, the vibration direction and perpendicular to the plane containing the direction of propagation of the plane of polarization is called. Natural light through the polarizer, the linearly polarized light can be obtained, often used in crystal optics research.
Polarized sunglasses can be divided according to purpose, ski goggles, fishing lens, polarized driving mirror, mirror outdoor sports, golf glasses. Polarized sunglasses can be classified according to the material, glass polarized sunglasses, polarized sunglasses resin material, and polarized sunglasses lens material. In the summer, fishing faithful like to wear polarized glasses. Reason is very simple, polarized sunglasses with polarized filter effect, wear it fishing, watching eyes drift easier and not tired, if the lenses are dark colored, for summer wear, I feel more comfortable. Cheap Ray Bans Wayfarer 2140 Sunglasses Outlet Polarized lenses are recognized worldwide as the most suitable for driving the lens. When the light reflected from the surface and partially polarized glare. Negative effects of glare, enhance brightness, color saturation weakened; make the object contours become blurred, so that the glasses fatigue, discomfort. Polaroid so made according to the principle of light polarization, with a special function effectively eliminate glare, light filtering disorganized, so motorists improved vision, adding to driving pleasure.
