How about Polaroid sunglasses? _Sunglasses knowledge_

Polaroid is the inventor of the polarizer and the market leader. In 1929, Dr. Edwinland invented the world's first polarizer and named it Polaroid. Polaroid sunglasses are very demanding in terms of lens requirements and fine workmanship. Let’s take a look at how Polaroid sunglasses are. Features of Polaroid sunglasses The frame is made of high-quality TR-90 material, which is rich in color, bright in color, light in texture, chemically stable, and not prone to allergies. The frame is made of high-grade alloy material, with fine electroplating, bright color and smooth texture. The texture of the temples is smooth and elastic, not easy to break. Polaroid nose pads are made of high-quality materials, exquisite workmanship, no irritation to the skin, no pressure. Polaroid sunglasses use renewable materials, adhere to sustainable development, and comply with environmental protection. The lens design is designed according to the curve of the Asian face to completely cover the line of sight to achieve the best filtering effect. Polaroid exclusive composite technology, 0 line of sight, laminated with 9-layer lens, the core module of the 9-layer lens is the polarizing filter layer in the middle layer, the upper and lower sides of the UV400 protective layer can isolate the intrusion of harmful light, and the outer layer is strengthened. It is used to protect the lens against impact and explosion. The outer hard layer protects the lens from scratches by hard objects. It is waterproof and oil-proof to make it easy to clean. Fully protect your eyes. Effective anti-glare, high-quality Polaroid TAC polarized lenses, eliminate glare reflected in the field of view, the field of view is clearer and natural, and relieve eye fatigue. It can effectively cut off ultraviolet rays and eliminate glare, but also insulate 100% ultraviolet rays. Do Polaroid sunglasses use original lenses? These lenses have the highest level of UV protection, 100% protection against UVA, UVB and UVC rays, enough to cover the entire harmful spectrum band, prevent cataracts, stay away from skin cancer, provide medicine and beauty Double effect. High clarity of field of view. The special film on the surface of the lens, a special film (anti-reflective blue film) formed by multiple evaporations, can greatly increase the perspective of the lens, so that the light behind the lens can directly pass through the lens, instead of being reflected on the eye, causing interference and causing interference. The vision is clearer. The thermal fusion technology used by Polaroid can make the lens bend while retaining its optical performance perfectly, allowing the wearer to move freely whenever and wherever possible. Look at the impact. Polaroid sunglasses not only meet comfort and fashion, but the lenses have strong impact resistance and exceed the requirements of various international safety standards. When an impact occurs, each layer of lens can disperse and absorb energy. Imported anti-skid screws are used to avoid the vibration and relaxation of the lens caused by repeated removal and wear, which effectively ensures that the lens is not easy to fall off and prolongs the service life of the lens. The color perception of the whole pair of glasses is accurate. With accurate color perception, it ensures the accuracy and clarity of the color of things, and is naturally free from falsehood.
