Cheap Nike Wholesale Roshe Run Caps Monster NMD Runner Beat Speaker Dock New Era 59fifty NewBalance 574 ZX750 Air Max 90 Jordan Retro 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.It can cause color distortion,such as such yellow lenses and sunglasses,but I will improve the contrast and sharpness.4,green lens,you can exclude the blue part,also,to reduce the glare effect.In all the colors of the lens,green lens,offers the highest contrast and maximum vision is so popular.5,the background of the green or blue,purple and pink lenses can provide the best contrast of the object.So they are suitable for hunting and water skiing.Many of the sunglasses manufacturer uses a process called constant density in order to give the staining of the lens.This is a whole mixture of glass or polycarbonate material has the same color,is the oldest sunglasses manufacturing process.Therefore,this method,in the manufacture of lenses,the lens is inside the collar.
Wholesale Beat Speaker Dock Molecules also,light plating layer on the surface of pure polycarbonate,it will absorb the dirt.The most common way for polycarbonate lenses,since the immersion of the lens in a special liquid including the inside of the coloring material,dyed colored substance is absorbed slowly by the plastic.If you want some of the dark,it will simply extend the immersion lens during the time of the liquid.PolarizationLight waves from an artificial light source such as the sun or a light bulb,it vibrates in all directions,has been popular.Light is propagated,whether 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,
Cheap Wholesale Nike Jordan Retroit 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 surface 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 surface,the reflected light is polarized in the same angular direction as the surface.Therefore,the high level of surface 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,the angle at a fixed polarized lens sunglasses.You,in the following way,will be able to comply with this principle.
Venta al por mayor barata NewBalance Such car hood,then observe the horizontal plane,please wear polarized sunglasses.It will head slowly to the left or right.You will find the glare from the surface changes as the adjustment the angle of the line of sight becomes brighter.Before buying,you can be made easy ?? test to identify their authenticity.Locate the reflecting surface,in order to observe the surface,through the lens,it took sunglasses.Slowly quarter turn sunglasses,decrease or increase and observe whether or not to reflect the glare.If you are a sunglasses polarized sunglasses,a significant reduction in glare appears.When mirroring below exposed to sunlight sunglasses,color is called the sunglasses and prescription glasses color glasses and darker.Lens principle of special chemical reaction depends on the UV.Several million of the molecules in the lens (for example,such as silver or silver halide chloride) contains a specific substance.If no ultraviolet ray is not present,visible light,can be transmitted through these molecules,it is the visible portion of a typical artificial light.When exposed to ultraviolet sunlight,but so that their shape is changed,these elements will pass through the chemical process.As the lens becomes dark,new molecular structure,will absorb some of the visible light.
