The well-known snow mirror brands currently on the market are really many, well-known Anon, Dragon, Julbo, Oakley, POC, Uvex, Vight and so on. For Xiaobian Xiaobai, it's really a mess of flowers. What are the key points to choose? Apart from visiting the ISPO Beijing 2018 (January 24-27, Beijing National Convention Center), what else should pay attention to the latest products and technologies? Xiao Bian rubs hard and skies the master skier and finally sets out these big truths! Let's knock on the blackboard for everyone now. 01 Anti-fog According to the actual use of the environment for objective selection. Different brands of snow mirrors perform differently under different conditions of use, and different types of products with the same brand have different fog and fog removal effects. At the same time, under the premise of different materials, position, design and wearing methods, the anti-fog effect will be different. However, when compared comprehensively, under the conditions of ordinary ski resorts, the anti-fog effect is proportional to the price. However, in case of extreme cold, if the face protection is not well-matched, no matter what brand, the anti-fog effect will be greatly reduced. At present, some international big brands of snow mirrors have adopted double-layer lenses, which can also effectively prevent the heat conduction inside and outside the lens from causing fogging; and a good style of the ventilation frame allows the internal air to circulate, automatically adjust the internal air of the frame, and can effectively keep warm And dehumidify to help prevent fog. 02 color change technology At present, color changing technology has become almost a weather vane for all-weather lenses. However, objectively speaking, all the principles of color change have their own degradation process, which means that it is impossible for them to be discolored as coolly as when they were newly bought. The discoloration performance may have a long or short life depending on the frequency of use, the environment, and the like. And the color change is not a panacea, has its scope of application, the scope of the effect is not as good as a single environment configuration of the lens. Also, discoloration should be fast enough and ideal enough. At the same time, there must be high-definition technology to adapt to the visual field requirements under various color differences. 03 Lens color In addition to the all-weather lens that can be changed in color, only one basic lens is needed to apply to all climatic conditions. But usually everybody will choose two lenses or more to adapt to the different light weather conditions. There is a problem with the transmittance of a lens. There are usually two methods of indicating light transmittance: l VLT notation: Visual Light Transmittance, visible light transmittance, expressed as a percentage. l CAT representation: Category Number, indicating the light transmittance rating. The relationship between CAT and VLT is: CAT-4 = 3% to 8% VLT CAT-3 = 8% ~ 18% VLT CAT-2 = 18% to 43% VLT CAT-1 = 43% to 80% VLT CAT-0 = 80% ~ 100% VLT Lenses are recommended to be coated, usually rhodium-plated. Their main function is to prevent glare and to obtain extra light balance. 04 box or no box? Most of the frameless snow mirrors advertised can increase the visual field, but in actual use, the limit of the visual field is more related to the inner frame. There is no frame does not have a great impact on the field of vision, and the lens of the frameless snow mirror is very easy to fingerprint. But no frame handsome! Beautiful! Pull the wind! At present, the frameless frame structures on the market are mostly equipped with more convenient lens switchers, which are much more convenient than the snap-on type. Generally, only one hand is needed, and the replacement of the lenses can be completed without taking gloves. However, under the guidance of an old ski driver, Xiao Bian personally recommends not to buy a magnetic suction type. This type is really convenient when used, but it is easy to drop the lens during strenuous exercise. The framed snow mirror also has a system that is easy to replace the lens, and when you use it in the woods, you will know the benefits of the framed snow mirror. Even if you accidentally get caught in the branches, it won't hurt the lens. Of course, the local tycoons Ignorable. 05 Select spherical or cylindrical mirror? Some people say spherical mirrors, especially parallax of large spherical mirrors will have distortion. In fact, this cylindrical mirror will also exist, but generally, such as participating in the many snow mirror brands of ISPO Beijing 2018, are specifically considering fidelity to eliminate distortion. The field of view of cylindrical lenses is not as good as that of spherical mirrors. However, in fact, the processing requirements of cylindrical mirrors are more demanding. Vertical flatness is to be considered. The number of spherical mirrors is more for single-board people, and the double-plate group seems to consider more cylindrical mirrors. Cylindrical lenses are usually used in professional athletic competitions. 06 Security The snow mirror products of Germany and the United States pay great attention to this technical indicator and have impact resistance tests. Tests included letting metal rods (greater than one pound) fall from four feet high and quarter inch steel shots run at 102 miles per hour. To resist the impact force of a light-weight object during high-speed operation by resisting the impact force of a heavy object at a low speed, it is also required to maintain the lightness and comfort of a high-quality material. Therefore, the spectacle of the snow mirror is really not just its appearance. The indicators behind these are very important. The ISPO Beijing 2018, which will be opened at the National Convention Center in Beijing from January 24-27, 2018, will have a deluxe lineup of over 42,000 square meters, more than 20 countries and more than 700 global brands. To ISPO Beijing 2018, let you see the world's most trendy professional ski equipment! At the same time suitable for sunny days, cloudy days, snow days POC all-weather large field of view snow mirror The unique lens produced in collaboration with industry leader Carl Zeiss introduces new levels of optical performance, optimizes contrast, and makes the field of vision clearer. It is suitable for three different weather conditions: sunny, cloudy, and snowy days. Grilamid Orb frames, combined with a simple lens change system with maximum field of view, provide unparalleled visual effects regardless of the weather. Julbo automatic color changing snow mirror that instantly solves fog problem In addition to double-layered lenses and anti-fog coating, the super-breathable system design has been added. When the vent hole is open, heat flow can be quickly achieved, thus thoroughly solving the problem of blurred vision caused by fog condensation. Even if the lens mist, as long as you open the vent hole can quickly let the fog spread, instantly solve the snow mirror fog problem, and the operation is simple and convenient, even with gloves can do the same.
