Outdoor driving, fishing, golf, mountain climbing, skiing, tourism, such as wearing dark glasses can be seen everywhere, not only can protect the glasses to avoid the ultraviolet radiation, can add luster for their image temperament more. But for most new to friend, what is called polarized sunglasses, polarized glasses what meaning be? These means may not understand, today small make up sunglasses factory spread to everyone. Sunglasses factory 9105 polarized sunglasses polarized sunglasses can block glare of uncomfortable, at the same time can protect your eyes from uv rays. All of this is due to metal powder filters, they can when light hits on the 'choice'. AIKUSTE of polarized sunglasses can selectively absorb the sun's rays of a part of the band, because it is through the thin metal powder ( Iron, copper, nickel, etc. ) 。 In fact, when the light on the lenses, based on the so-called 'destructive interference' process, the light is reduced. In other words, when certain wavelengths of light ( Here refers to uva, uvb rays, and sometimes infrared) Through the lens, the lens inside the eye direction, they will cancel each other out. Formation of overlapping of waves is not an accidental phenomenon: a wave crest with the wave trough of near together, leads to cancel each other out. Destructive interference phenomenon depends on the lens refraction coefficient ( The different material from the air through the light when the degree of deviation) , also depends on the thickness of the lens. Little change in general, the thickness of the lens, the lens refractive index was based on the differences of chemical composition and different. Polarized sunglasses offers another eye protection mechanism. The asphalt reflected light is a special polarized light. The reflected light and the light from the sun directly or any artificial light source the light is different from the problem lies in the order. Polarized light is made up of all in one direction vibration wave form, and the light of the general is by not directional vibration wave into the open. It's like a group of people walk around with a group of no order with neat pace of marching soldiers, to the stark. This like the original shutters, light from one direction to come in, in addition to the clutter of light, so the view will be clear.
