The principle and function of anti-UV glasses

There are three types of light emitted from the sun: visible light, infrared rays, and ultraviolet rays. Among them, ultraviolet rays cause serious damage to human skin, eyes, etc.; IR (Infra-red) infrared rays ( 750mm) and above, visible light lay (310~780nm); ultraviolet rays are divided into UVA, UVB, UVC (310nm) and above, blue light (Blue light) among which UVA, UVB, UVC It is a harmful ray. If exposed to the sun for a long time, it will cause damage to the body. UVB has a serious impact on vision. (Tanning Ray) is a ray that burns the skin black. Most of the corners of the eyes will absorb this kind of UVB ray, so you must block it. light source. Because polarized sunglasses have the function of polarizing light, they can block all harmful rays without affecting the transmission of visible light, and can truly protect the eyes. ​

Natural light (non-polarized aurora) is actually composed of electromagnetic waves that vibrate in a specific direction, and the reflected or scattered light usually prefers a specific direction. This is why polarized sunglasses can filter out sunlight reflected from car roofs or pools; after natural light is filtered by polarized lenses, it can only allow light in one direction to pass through, which means that polarized lenses can first polarize the light. After polarization, only light in one direction is allowed to pass (visible light). Polarized sunglasses use this feature to block harmful light, because sunlight will produce harmful glare due to natural reflection or refraction no matter it touches any object. Polarized sunglasses can completely absorb these strong lights that can cause dazzling and eye damage.
