Bring sunglasses as everybody knows, sunshade uv! But I often hear someone says polarized sunglasses, at that time a lot of people are zhang two monks confused. What exactly is polarized sunglasses? What is the difference between polarized sunglasses and sunglasses again? Let's analyse in detail. What is a polarized sunglasses? Polarization is refers to the light through a bumpy roads, water and other places, the irregular reflection, also known as glare. The light of direct illuminate the eyes, can make the person eye discomfort, fatigue, easily not lasting vision, depending on the definition of a body is obviously not enough. Sunglasses factory YC9702 general sunglasses C1 black box white leg/lens dazzle colour silver and polarized sunglasses with metal powder filters, they can when light hits on the 'choice', can selectively absorb the sun's rays of a part of the band, has the function of the polarization of light. Polarized sunglasses in addition to the basic uv protection function, but also has anti glare, pavement reflect light, the surface scales such as light, suitable for driving, fishing, travel, daily wear. The difference between polarized sunglasses and sunglasses: 1, the principle of different sunglasses is through the lens surface film layer and add anti UV lens material particles to absorb ultraviolet light, mainly using the color of the lens to block the light, the lens is what color, you see things is what color, can make the loss of color vision. Ray-ban sunglasses RB4225 men 646/55 transparent polarized sunglasses is by using the theory of polarized light, the color of the silicon crystal coating will be arranged in vertical direction of the light, like the shutter will parallel light cover, which block the glare that is harmful to the eyes, can see objects will not change color. 2, the function different from the ordinary sunglasses has the function of blocking ultraviolet (uv) and polarized sunglasses has the function of sunglasses + polarization can not only cut off ultraviolet (uv) light, also can filter out glare, scattering light and refracted light. It absorbs the reflection of the object itself, only can truly present the object color, can reduce the eye fatigue, increase the color saturation, can really play the role of protecting our eyes. 3, different level of blocking ultraviolet rays, ultraviolet light is invisible killer of mankind, polarizer is therefore arises at the historic moment, for uv blocking rate reached 99%, while the common dyeing lens blocking rate is low. Another small make up remind everybody, while driving to view request is very high, not only need to block the glare, to keep the object color constant, so as to clearly identify traffic lights, can also reduce eyestrain. So the driver must choose high quality polarized lenses.
