Polarized light，English namepolarized light "Explanatory Text：Also known as polarized light。Visible light is a transverse wave，Its vibration direction is perpendicular to the direction of propagation。The vibration direction of natural light，It is arbitrary in the plane perpendicular to the direction of propagation；For polarized light，Its vibration direction is at a certain moment，Be confined to a specific direction。In life，Too many light sources can produce harmful light，Especially sunlight；The light emitted in sunlight includes：可视"Light"、Infrared rays、Ultraviolet rays(Ultraviolet)The other three types。当中以Ultraviolet rays对人体的皮肤、Eyes, etc.，Cause serious harm；Too much above，可视"Light"（Visible light ray）（310~780nm）；Ultraviolet rays can be further classifiedUVA、UVB、UVC（310nm）Above，Qingguang（Blue light）Among themUVA、UVB、UVC是有害"Light"，Prolonged exposure to the sun can cause damage to the body，UVBIt has a serious impact on eyesight，（Tanning Ray）是烧黑皮肤的"Light"，Most of the corners of the eyes will absorb thisUVB"Light"，So it is essential to block this kind of light source。Polarized sunglasses have the function of polarizing light，所以能将所有之有害"Light"都阻隔掉却不影响可视光的透过，It can truly achieve the function of protecting the eyes。In addition to the basic function of UV protection, polarized sunglasses，It also has anti-glare properties、路面反射"Light"、Water surface scale light, etc，Suitable for driving、Fishing、Tourism、Daily wear。UV（防Ultraviolet rays程度）UVThe meaning of a standard refers to：人眼对"Light"的感知范围是380~780nm（That is, visible light），Ultraviolet rays是指波长低于380nm的"Light"（Invisible light）。UV380The meaning is that it can effectively block wavelengths380nmThe following light。whileUV400The standard also blocks some visible light at the same time，So some colors will be lost。Polarized light（Polarized light、Polarization filter）Color saturation，Make the outline of the object blurred，Cause eye fatigue、"Uncomfortable"。Polarized light片是根据"Light"的偏振原理制成，That is, when the vibration plane of light is parallel to the polarization axis，Polarized light滤光片才能使Polarized light透（Just like the principle of blinds）。因while，"Light"被整理成同向光进入人眼，使周围景物看起来清晰while不刺眼。Another prominent advantage is that the film is extremely light、Extremely thin（Thickness0.8mm、1.1mm ）And impact-resistant，所以这种镜片非常Suitable for driving及户外活动时配戴，It has been widely favored in recent years。

Drivers tend to wear polarized sunglasses，Because polarizing filters can not only block ultraviolet rays，It can also minimize and filter out the reflected strong light glare to the greatest extent。For instance, the strong headlights of the oncoming vehicle when driving，Or the vehicle in front is blocked by the reflective stickers on the rear windowUV的窗贴膜被太阳照射while形成的强眩光，Enable the wearer to clearly see the things in front。
