When People Wear Polarized Sunglasses, How They Watch Advertising?
Principle of Polarized Sunglasses
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, which is why polarized sunglasses can filter out reflections from the roof or pool Because of the coming sunshine;
After the natural light is filtered by the polarized lens, it can only let the light in one direction pass. That is to say, the polarized lens can polarize the light first, and only allows the light in one direction to pass (visible light).
Polarized sunglasses use this feature to block harmful light, because no matter what the sun is touching any object, it will produce harmful glare due to natural reflection or refraction.
Polarized sunglasses can completely absorb these glare that can cause dazzling and eye damage.
Functions of polarized sunglasses
In life, there are too many light sources that can produce harmful light, especially sunlight; the light emitted from the sunlight includes three types: visible light, infrared light, and ultraviolet light.
Among them, ultraviolet rays cause serious damage to human skin, eyes, etc.;
Among the rays released by the sun, 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) of which UVA, UVB, UVC are harmful light, if exposed for a long time will cause damage to the body, UVB is a serious impact on vision, (Tanning Ray is the light that burns the skin, most of the corners of the eyes will absorb this UVB light, so this light source must be blocked.
Polarized sunglasses have the function of polarizing light, so they can block all harmful light without affecting the transmission of visible light, which can truly protect the eyes.
Application of polarized sunglasses
Polarized sunglasses can block 100% harmful light, so they can be used in:
1. Medical treatment: For patients undergoing eye surgery, all-round protection is required. Polarized sunglasses are the best choice.
2. Outdoor activities: such as skiing, fishing, water activities, etc., all need sunglasses that can completely block harmful light to avoid eye injury or fatigue.
