Polarized sunglasses

It can block uncomfortable strong light, while protecting the eyes from ultraviolet damage.All this is due to the metal powder filtering device, and they can do it when the light is shot“Choose”EssencePolarized sunglasses can selectively absorb part of the band of sunlight, because it uses fine metal powder (iron, copper, nickel, etc.).In fact, when the light is shot on the lens, it is based on the so -called“Interference”In the process, light was reduced.In other words, when some wavelengths (here refer to UV A, UV B, and sometimes infrared), when you pass through the lens, they will offset each other in the inside of the lens towards the eyes.The overlapping of light waves is not accidental: a wave of wave peaks together with the wave valley near its waves, which causes offset each other.The phenomenon of phase -dismissal depends on the refraction coefficient of the lens (that is, the degree of deviation between the light from the air through the air) and the thickness of the lens.Generally speaking, the thickness of the lenses does not change much, and the refraction coefficient of the lens vary depending on the difference in chemical composition.
Polarized sunglasses provide another mechanism to protect the eyes.The reflection light of the asphalt road is a special polarized light.The difference between this reflection light and light from the sun or the light of any artificial light source lies in order.The polarized light is formed by the waves of vibration in the whole direction, and the general light is made of waves that are inferior to vibration.This is like a group of people who walked disorderly and walked at will and a group of soldiers who walked neatly to form a clear pair.Generally speaking, reflection light is an orderly light.Polarized lenses are particularly effective when blocking this light because its filtering is playing.This kind of lens only allows the polarized waves that shocked in a certain direction, just like the light“Sort out”For the same way, the use of polarized sunglasses with polarized sunglasses can reduce the transmission of light, because it does not allow the light waves that vibrate parallel to the road.In fact, the length of the filter layer is guided by the horizontal direction, which can absorb horizontal polarizing light.In this way, most of the reflected light is eliminated, and after the entire lighting of the surrounding environment is not reduced, the lens of the polarized sunglasses can be darkened after the sun is shot.After the lighting weakened, it became bright again.The reason why this is because of the crystallization of silver silver.Under normal circumstances, it can keep the lens transparency.Under the irradiation of sunlight, the silver in the crystal is separated, and the free silver is formed by a small cluster inside the lens.These small silver clusters collectively have irregular blocks of dog teeth. They cannot transmit light, but can only absorb light. As a result, the lens darkens.In the case of light and dark, the crystals are re -formed, and the lenses will return to a bright state
