Lens principle of special chemical reaction depends on the UV

The manufacturer uses different colors to produce a certain efficiencySunglassesSunglassesFruit.1,gray,while reducing the distortion of minimal color,good general color is brightness.Gray lens is driven and is ideal for general use,it will provide glare protection.While other frequencies to allow more light through the lens,2,golden and blue of the lens can be reduced.Blue light,it is possible to bounce a lot of dispersion can be obtained glare effect called blue haze.All objects,as will be bright and vivid display,in fact,the yellow is given,will be able to eliminate the blue portion of the spectrum.Anti-snow blindness generally,the reason for the yellow sunglasses is for this.Such colors,in order to identify a person in need of color perception accurate color activities,less such distortion not suitable for colored sunglasses will way.3,it is also a good general color of amber and brown.These,in addition to the UV that it is possible to reduce the effect of glare,unique molecules can also be blue,etc.,the color of the higher frequency,can be absorbed.Studies have shown long-term acceptance of near-ultraviolet light (for example,blue-violet,etc.) radiation is one of the causative factors of cataract.

Samsung GALAXY 5whether reflected is a divergence or refraction,when the light it is in one or more planar direction of vibration,we called the polarization of light.Polarization treatment,can be present naturally or artificially stimulated.When the lake is a natural example of each observation polarization,you can see the glare.Reflected glare from the lake,the water is despite the very clear reason so that they do not reference any object in the lake,it will not be able to pass through the why some water "filter" light.Polarizing filter is a thin film by chemical plating layer on the su***ce of the typically configured transparent plastic or glass.Typically,compounds used in the molecule is essentially are parallel to each other.If they are they are coated on uniformly lenses,these molecules will form small lenses which can absorb all arranged in the same direction as the light.You must wear a forced sunglasses most of the glare,as in the water and high-speed road,it comes from the horizontal plane.When light reaches the su***ce,the reflected light is polarized in the same angular direction as the su***ce.Therefore,the high level of su***ce reflection,for example,like a lake,can be produced in large quantities in the horizontal polarization.Only as vertically polarized light passes through the lens,and therefore,
