| Message: | 1.Considering the development in a long term of the future, the Changsha Mingxuan Jewelry Co., Ltd. will put into practice a new development philosophy, seek high-quality growth, and build new images of Chinese foreign trade. Company profile is:4.Sunglasses, also known as sunshading, for sunshading. In the sun, people usually adjust the size of the pupil to adjust the luminous flux, and when the intensity of the light exceeds the ability of the human eye to adjust, it can cause harm to the human eye. Therefore, in the outdoor activities, especially in the summer, the sun-shading mirror is required to shield the sunlight so as to reduce the damage caused by the fatigue or the strong light stimulation caused by the adjustment of the eyes. Sunglasses can shield the uncomfortable light while protecting the eye from the damage of ultraviolet light. All of this is due to the metal powder filter, which can be "Select" when the light is incident. The colored glasses are capable of selectively absorbing the composition of the sunlight. Part of the band of the line is due to its fine metallic powder (iron, copper, nickel, etc.). In fact, when light hits the lens, it is subtracted based on the so-called de-interference process. The lenses only allow polarized waves that vibrate in a certain direction to pass, as if the light had been "combed". For road reflective problems, the use of polarized glasses can reduce the transmission of light because it does not allow light waves that vibrate parallel to the road. In fact, the long molecules of the filter layer are directed horizontally to absorb horizontally polarized light. In this way, most of the reflected light is eliminated, and the entire illumination of the surrounding environment is not reduced. . As being great supplier in the world,Mingxuan Jewelry must try their best effort for providing the better service and products,only by this way Changsha Mingxuan Jewelry Co., Ltd. can make great success and being successfully in |
