So,in outdoor activities,especially in the summer,you must block the sun visor mirror to reduce the adjustment eye fatigue and light stimulate the harm caused.SunglassesEffect of sunglassesWhile protecting the free eye,sunglasses will be able to block an unpleasant glareSunglassesSunglasses (6)By UV damage.All this,thanks to the metal powder filters,they "choices" is that it can light hits.Colored glass,selectively,for very fine,
yeezy 350 blackby using a metal powder (iron,copper,nickel,etc.),you will be able to absorb some of the band composition of the sun of light.In fact when light illuminates the lens,based on the process of the so-called "destructive interference",the light has been cut up.That is,specific wavelengths of light (in this case,the times,UV A,UV B,an infrared),when passing through the lens,the inner lens of the eye in a direction,kill their phases with each other,It is.It is not a coincidence by forming the optical wave overlapping phenomena.
Chaussures New Balance 574 FemmeIn its close to the wave trough crest together,it led to cancel each other out.Destructive interference,depending on the thickness of the lens,(when the light is passing through the different materials from the air,namely,the degree of the deviation is occurring) lens depends on the refractive index of.The refractive index of the lens,while based on the difference of different chemical compositions,in general,will slightly vary the thickness of the lens.Polarized glassesPolarized glasses you are wearing effectPolarized glasses and provides a mechanism to protect the other eye.Special asphalt reflected polarized light.This reflected light,sun light or any issues to the different from the direct light from an artificial light.Polarization of one direction by the entire shock wave formation,and general light is not instructed by the shock wave is formed,it is like a group of disorderly people,but as the pace of travel,you can walk around with a group of marching soldiers,
Casquette Monster Energy The Stark against penetration.Generally speaking,it is reflected light orderly light.Since the filter is working,polarized lenses,is particularly effective in blocking the light.This lens is by the same,shock as only light "comb",enables the direction of polarization.It to the to prevent the vibration of light passing through,since it is parallel to the road,due to the road su***ce reflection problem,
nike air max 2016 women the use of polarized glasses,reduces the transmission of light.In fact,it is directed to the filtration layer of the long molecules horizontally,it is possible to absorb the horizontal polarization.While to the entire lighting of the surrounding environment is not reduced,the majority of the reflected light,will be removed.Color glassesThe lens can be taken after a dark colored glass in the light of the sun.After the lighting has been weakened,it will be bright again.Therefore,we were able of silver halide crystals in the workplace.Under normal circumstances,we will make a perfect lens to hold the transparency.Under irradiation of sunlight,in free form crystals silver inside the lens of the silver is separated,to form small aggregates.

These small silver substantially aggregate irregular block of jagged,it is not possible that they are transmitted through the light,only the results of the lens to be dark,it can absorb the light.No,the crystals formed in the case of light and darkness heavy,lens it was returned to the bright state.2 basic functions ForewordSunglasses,there are two sheets of colored glass or plastic,it is a some kind of plastic or metal frame,you very easily visible.
