The ski mirror is essential for skiing people, and it is very important to choose the right skiing mirror because of the great reflection of the snow in the snow and the intense stimulation of the eyes on the cold wind.
Whether you are a master or a beginner, the right ski mirror must have the following basic functions:
1, anti-fog, mirror fog will be fuzzy skiers of sight, it is easy to accident;
2, anti-ultraviolet, snow reflection of the sun strong, Ski Goggles strong ultraviolet light will burn the eyes;
3, wind, whether you are skilled, taxiing cold wind on the eyes of the stimulus;
4, preferably double-layer resin, even if the impact will not cause damage to the face.
5, a breathable mouth, in the frame of the eaves on the use of breathable sponge made of breathable openings, so that the facial skin heat discharged to the mirror, Ski Goggles to ensure that the mirror has a good visual effect.
How to choose a ski mirror
One, enough strength. First of all to ensure that the snow mirror is not easy to break the impact, not easy to cause damage to the eyes and face. If you buy a snow mirror, which shop clerk to assure you that his snow will not be absolutely safe damage, that is, "call". There is no damage to things, Ski Goggles even if the steel is no exception, just look at the impact of the power and location. To know, is the best snow mirror, training a large professional small rotary athletes will be bounced every year, the flagpole hit several snow mirror! Good snow mirror really better strength, Ski Goggles the ability to absorb more impact, the probability of damage even lower. This kind of snow mirror needs high quality frame, lens and glue, high strength resin is the manufacture of the frame, the mainstream of the lens material, and from the current production costs at home and abroad, the retail price of 100 or even 100 within the snow mirror is often The use of some ordinary or slightly reinforced plastic materials, Ski Goggles its quality is difficult to guarantee. A lot of wholesale markets to sell glasses and sunglasses shops also have a similar ski mirror or goggles, the appearance of fancy, but in the hands of a slight force twist, creaky voice is really worry about this lens frame will not be a slight impact on Will rupture, hurt the glasses and face.
Second, good anti-fog ability. There is no difference between wearing snow and snow. Snow mirror anti-fog effect depends on three ways to achieve: snow within the appropriate ventilation, Ski Goggles to keep the lens inside and outside the temperature difference, the lens inside the anti-fog coating. The first point of the role is to reduce the concentration of water vapor within the snow, but it will not make it condensed into a fog; after 2:00 is to make the snow inside the warm air even if the humidity is large, Ski Goggles it is not easy to condense on the lens The The ventilation of the snow mirror through the snow and the upper and lower contact with the face of the breathable sponge to achieve, the key to ventilation is to control the size of the ventilation: to ensure that the snow within the warm air can pass through the upper part of the snow sponge as soon as possible, From the lower part of the snow sponge dry cool outside the air too much too much into the snow mirror caused by the lens speed cold, Ski Goggles snow within the saturated water vapor quickly condensed the situation, thereby reducing the lens fog. To this end, some high-end snow mirror also designed a special ventilation control system, a wider range of regulation and control of ventilation.
Third, match with the face match. Pick must be try! Especially in the snow under the contact with the face and nose part of the nose, to fit, to prevent the nose and mouth exhaled water vapor mixed with cold air into the snow mirror, causing serious fog. While preventing cold air blowing, to stimulate the eyes. Ski Goggles Some helmets can also try to match the snow mirror and helmet, in general, the vast majority of snow and helmets can be worn between each other, there may be snow and helmet gap between the differences. Asian and Europe and the United States: white and yellow people face different, suitable for snow mirror style is very different. Ski Goggles Europe and the United States nose high, the mainstream snow mirror style arch in the middle of the arch is very high, most Asians wearing a nose around the air, resulting in cold wind and snow mirror fog serious, for this, most people choose the Asian brand or European brand improved Asian style is good
Four, high-definition. The lens is smooth and smooth, Ski Goggles the lens material even no impurities, can guarantee to see things clear, no deformation, the eyes will not wear long wear. The problem lens will hurt eyesight.
5, the appropriate light transmittance (usually said that the lens color depth). Reduce the sun and snow reflection of the light, to avoid snow blindness and eye fatigue. Often play the night or the back of the snow should be selected light and accompanied by light to highlight the lens, often slip daytime sunny snow field selection of dark lenses, all kinds of conditions are slippery selected color depth of the lens. Ski Goggles And some discoloration of the snow mirror and can replace the lens of the glasses, you can better adapt to different weather, sooner or later and different facing the snow
Six, isolated from ultraviolet light. Protect the eyes and prevent sunburn. General professional snow mirror UV isolation rate of more than 99%, basically do not worry. In fact, I personally feel that the isolation rate of more than 90% are no longer meaningful, the sun every day suitable for the sun harmless, Ski Goggles unless it is engaged in welding or UV disinfection work
Seven, spherical and cylindrical. Spherical mirror is the rise in recent years, before the mainstream is a cylindrical mirror.
The main difference between the two is:
1, the visual error: in the case of glasses, visual level, spherical and cylindrical mirror horizontal level error is the same; but in the eyes looking up and overlooking the cylindrical mirror than the spherical mirror of the vertical error gradually increased. This is the player and the double board in the slide fly and grind style (Feiteng, somersault, rotation and steel and U-slot) players often need to look up and look down, somersault need more precise control action and placement, often choose The reason for the spherical mirror; of course, the spherical mirror looks more publicity, but also in line with this style.
2, the spherical structure is relatively stable than the cylinder, more resistant to impact.
3, because the head is long and long oval ball type, especially when wearing helmets and cylindrical mirror, the overall head of the head of the smaller wind resistance, and double board racing players in the gliding line of sight to maintain the level, so almost All the double board racing players are almost all selected for the cylindrical mirror.
4, the same degree of protrusion, cylindrical space within the larger, so almost all of the glasses designed to wear myopia, are cylindrical mirror.
In addition, the spherical mirror with color or chrome mirror as the coating, looking really more modern, more in line with the current aesthetic trend.
Eight, double and single layer. Double-layer lens protection ability is stronger, anti-fog ability is higher. Generally the same snow mirror, single and double the spread in the 100-200 yuan. Individuals need to choose according to economic conditions. Double lenses are also different, two lenses are sealed, Ski Goggles and some of the two lenses around a circle with rubber or sponge pad paste together. The former anti-impact and anti-fog ability better than the latter. Some of the middle of the double-layer lens is drawn into a vacuum, I personally do not agree, because the thin soft double-sealed resin lenses, if the middle is a vacuum, the middle of the two lenses will be outside the atmospheric pressure paste together , Or at least retraction, but the actual observation is not the case. Ski Goggles So the seal between the double-layer lenses should be filled with the moisture to remove the air or nitrogen, both anti-fog, but also slow down the aging of the lens.
Nine, different colors of the lens selection. Different colors have different characteristics: Silver lenses: the most significant reduction in brightness, Ski Goggles suitable for use in strong sunlight. Smoke Gray Lens: Reduce the brightness, natural colors, suitable for ordinary sunny days. Dark blue, blue, purple lenses: absorb the dazzling yellow. Green lenses: eyes are not tired, suitable for all day wear. Red lens: light dark, you can improve the naked eye on the warm color recognition ability. Brown lenses: enhanced contrast, twilight, cloudy, lack of light to use, to maintain a clear vision. Yellow lenses: by light, so that the vision clear and clear, suitable for morning, evening and other light the darkest situation. There are many other colors, the characteristics of this do not go into details.
