u003cbru003eFashion, beauty, and radiation protection, these features of sunglasses make people like wearing sunglasses more. However, the editor reminds everyone that when choosing sunglasses, you can't just focus on the style, but ignore the quality of the sunglasses themselves. Do not wear the following four types of unqualified sunglasses. The first type of sunglasses with anti-ultraviolet function is not worthy of its name. Good sunglasses lenses can block more than 99% of ultraviolet rays, and the lenses marked with UV400 can block 100% (99.99%) of ultraviolet rays. Inferior glasses due to their poor UV protection function or even lack thereof, which causes a large amount of residual UV rays to be absorbed into the enlarged pupils, causing varying degrees of damage to the eyes. The second type is sunglasses with unqualified transmittance. Glasses with qualified transmittance can clearly identify colors. Inferior glasses can cause traffic signal identification obstacles, which can easily cause traffic accidents. The third type, sunglasses without category identification. Sunglasses are generally divided into three categories, namely, sun-shading mirrors for sun protection, light-colored mirrors for decoration, and special mirrors for preventing snow blindness or water-proof plane radiation. The fourth type is sunglasses whose resistance performance does not meet the requirements. The lens is easily broken when impacted by an external force, and the fragments can cause fatal damage to human eyes. The material of the frame is also very important. Generally, there are plates, aluminum-magnesium alloys, and pure titanium. Related Reading: Sunglasses Brand Sunglasses
