What are polarized sunglasses

When sunlight hits the surface of an object, it will cause glare due to reflection. The glare will increase the brightness (this kind of light is very dazzling), weaken the color saturation, make the outline of the object blurred, and make the eyes tired and uncomfortable. Ordinary sunglasses can only reduce the transmission intensity of light, but cannot eliminate glare. Polarized sunglasses have a priority to eliminate glare. Its principle is similar to blinds. Polarized sunglasses also have a single-direction polarization axis like blinds in the lens, which can effectively filter the incident light. When the light passes through the lens, it is Arranged into the same direction of light enters the eyes, which makes the outside scenery look clearer and soft and not dazzling. Therefore, polarized sunglasses (various luminosity can be customized) have a special effect on improving vision for drivers and passengers, and fully experience driving pleasure. Ultraviolet 　　The electromagnetic wave with wavelength 10-380nm is ultraviolet 1. The wavelength of 315-380nm is ultraviolet A, which is one of the causes of cataract. 2. The wavelength of 280-315 nm is ultraviolet B, which is one of the causes of acute corneal conjunctiva. 3. The wavelength below 10-280 nm is ultraviolet C, which is quite harmful to the growth and development of organisms. Polarization principle 1. Polarized lenses are designed and manufactured according to the principle of volatility and polarization of light and the principle of shutters, which can effectively reduce glare, eliminate dazzling reflected light and scattered light, and turn messy light into parallel light, making the object visible More clear, soft and clear. 2. The polarization angle and arc of the polarized lens are professionally designed and processed, so that the wearer will not have the feeling of distortion and dizziness. 3. The polarizer is composed of 7 layers of materials, which meets the national sunglasses lens standard and UV400 ultraviolet standard, and protects the eyes in all directions. The first layer is the polarizing layer, which is the core of the lens, providing more than 99% of the polarizing effect and effectively absorbing glare. The second and third layers are adhesive layers, which can effectively resist cutting, baking, bake bending, and cutting, and can withstand the test of harsh environments. The fourth and fifth layers are ultraviolet absorbing layers, which can absorb more than 99% of UV ultraviolet rays. The sixth and seventh layers are anti-impact layers, providing good toughness and impact resistance, effectively preventing the lens from scratching and prolonging the life of the lens.
