What are the functions of Ski glasses
Ski mirrors are essential for skiing people. Because the sunlight reflection in the snow is very powerful, and the cold wind is very irritating to the eyes, it is very important to choose the appropriate Ski mirror.
Whether you are a master or a beginner, the right Ski mirror must have the following basic functions:
1. Anti -fog, mirroring fog will blur the sight of Ski people, and it is easy to accidentally accidentally.
2. Anti -ultraviolet rays, the sunlight reflection in the snow, strong ultraviolet rays will burn their eyes.
3. Wind -proof, whether you are skilled or not, the cold wind will stimulate the eyes when gliding.
4. It is best to be a double -layer resin. Even if it is impacted, it will not cause damage to the face.
5. There is a breathable mouth. The upper eaves of the outer frame are used with breathable mouths made of breathable sponges, so that the thermal air discharged from the facial Skin is spread out of the mirror, ensuring that the mirror has a good visual effect.
Which Ski mirror is good
The price of foreign brands is very expensive, and the price of foreign brands sold in China is very outrageous. The price of $ 170 abroad is sold to $ 290 in China. In addition to taxes, there are more profits of dealers.Most of the foreign brands are around 1700 yuan, and most of the domestic brands are below 200 yuan. It is suitable for snowfield tourists.
Buy suggestion:
1. Beautiful perspective, more or less consider matching the color of your favorite skiwear.
2. Quality first, no matter what, skiing is a dangerous movement. It must be the best selection within the scope of the price scope you can bear.
3. Although the snow mirror is a small part of skiing equipment, it also needs to be complete. You can carry a small cloth bag with a snow mirror with you.
4. It is highly recommended that the spherical mirror, the view of the spherical mirror is wider, and its impact resistance and anti -deformation ability greatly exceed the column surface lenses.
How to choose Ski mirror
1. enough strength
First of all, it is necessary to ensure that the Ski mirror is not easily broken by impact, and it is not easy to harm the eyes and faces.There is no thing that will not be damaged, even if it is steel, it is no exception, just to see the power and location of the impact.You know, it is the best snow mirror at present. The professional small rotary athletes with a large amount of training are also destroyed by the flagpole every year!Good snow mirrors do have better strength, stronger ability to absorb impacts, and lower probability of damage.This type of snow mirror requires high -quality frames, lenses, and glue. High -strength resin is the mainstream materials for making frames and lenses. From the current cost of production at home and abroad, snow mirrors with retail prices at more than 100 or even 100 are often still still more than 100 or even 100.It is difficult to guarantee the use of some ordinary or slightly enhanced plastic materials.Many wholesale markets selling glasses and Sunglasses also have similar Ski mirrors or wind mirrors, and the appearance is made of a whistle, but it is slightly twisted in my hand. The creak sound really makes people worry about whether this lens frame will be slightly impact.It will break, wound glasses and faces.
2. Good anti -fog ability
There is no difference between the Ski mirror wearing the fog.The anti -fog effect of the Ski mirror relies on three ways to achieve: the appropriate ventilation inside the snow mirror, the temperature difference between the inside and outside of the lens, and the anti -fog coating in the inside of the lens.The role of point 1 is to reduce the concentration of water steam in the snow mirror, but it will not cause them to condense into fog sharply; the latter 2 is that the warm air in the snow mirror is not easy to condense on the lens even if the humidity is very large, it is not easy to condense on the lensEssenceThe ventilation of the snow mirror is realized through the breathable sponge of the face and facial contact with the snow mirror. The key to ventilation is to reasonably control the size of the ventilation volume: to ensure that the inside warm and humid air in the snow mirror can be discharged as soon as possible through the sponge on the upper part of the snow mirror, and it will not use it to prevent it.The dry and cool outer air from the sponge under the snow mirror is too fast to enter the inside of the snow mirror to cause the lens to be cold, and the saturated water vapor in the snow mirror quickly encounters the cold condensation, thereby reducing the lens fog.To this end, some high -end snow mirrors also have a special ventilation regulatory system that can regulate and control the volume of ventilation.
3. Matching with the face shape
You must try to choose!In particular, the parts of the lower edge of the snow mirror should be in line with the facial and nose bridge, to prevent the water vapor of the mouth and nose from being mixed with the cold wind into the snow mirror, causing a severe mist.At the same time, prevent cold wind from blowing in and stimulating the eyes.Some of them can also try the matching of snow mirrors and helmets. Generally speaking, most snow mirrors and helmets can be worn with each other. There may be differences between the gaps between the snow mirror and the helmet.Asian and European and American models: White and yellow people have different faces, which are very different for snow mirror.European and American nose is high, and the style of mainstream snow mirrors is high in the middle. Most Asians wearing nose will leak wind, causing cold wind to blow their eyes and snow mirrors in a serious fog. For this reason, most candidates have improved Asian brands or European brands.Asian style is better.
4. High -definition
The lens is Smooth and Smooth, and the material of the lens is uniform and no impurities. Only in order to ensure that it is clear, no deformation, and the eyes of the eyes will not be fatigue.The problem lens hurts the vision.
5. Appropriate light transmission rate
It is the depth of the color of the lens that people usually say.Reduce the strong light of sunlight and snowfields to avoid snow blindness and eye fatigue.Those who often skate the night market or shade and snowy areas should be selected with light -colored lenses with light increase and brightening. Frequent dark lenses of the Yangxue Farm in the daytime, and various conditions are Smooth.There are also some discolored snow mirrors and glasses that can replace lenses, which can better adapt to different weather, morning and evening, and different directions.
6. Separate ultraviolet rays
Protect your eyes and prevent sunburn.The isolation rate of general professional snow mirror ultraviolet rays is above 99 %, so there is no need to worry about it.In fact, I personally think that this isolation rate of more than 90 % is no longer meaningful, and the sun is not harmless to others every day, unless it is engaged in welding or ultraviolet disinfection.
7. Ball and column
The spherical mirror has risen in recent years, and the mainstream was the column mirror before.The main differences and features of the two are:
(1) Visual error: In the level of glasses, the horizontal error of the left and right of the spherical mirror and column mirror is the same; but when the eyes look up and down, the vertical error of the column mirror is gradually increased than the vertical error of the spherical mirror.This is the players of the single board player and the dual -board medium slipfer and grind style (flying, air turning, rotation, steel pipes and U -shaped grooves). Because they often need to look up and down, they need more accurate control actions and falling points. They often choose to chooseThe reason for the spherical mirror; of course, the spherical mirror looks more public, and it is in line with this style.
(2) The sphere is relatively stable and more resistant to impact than the column surface structure.
(3) Because the head is an elliptical ball type with a long up and down, especially when wearing a helmet and column mirror at the same time, the overall front wind resistance of the head of the head is smaller, and the double -board racing players are basically maintaining the level at the slide. ThereforeAlmost all the double -board racing players choose almost all column mirrors.
(4) The same protrusion level, the space inside the column mirror is greater, so almost all the snow mirrors wearing myopia mirrors are almost designed.
In addition, after the spherical mirror with color or chrome -plated mirror coating, it is indeed more modern and more in line with the current aesthetic trend.
8. Double layer and single layer
Double -layer lens protection capabilities are stronger and the anti -fog ability is higher.Generally, the same snow mirror, the price difference between a single layer and double layer is 100-200 yuan.Individuals need to choose according to economic conditions.The double -layer lenses are also different. Some of the two -layer lenses are sealing, and some two layers of lenses are pasted with rubber or sponge pads around a circle.The former's anti -impact and anti -fog ability is better than the latter.Some say that the two -layer lenses are pumped into vacuum in the middle. I personally do not agree, because the thin and soft double -layer seal resin lens, if the middle is vacuum, the middle part of the two layers of lenses will be pressed together by the outside atmosphere.Or at least the trap, but the actual observation is not the case.Therefore, between the two -layer lenses, the air or nitrogen gas that removes the moisture should be filled, which not only prevents the fog, but also slows down the lens oxidation and aging.
9. The choice of lenses of different colors
Different colors have different characteristics: silver lens: minimize the brightness, suitable for strong use in the sun.Smoke gray lenses: reduce brightness, natural color, suitable for ordinary sunny days.Dark blue, blue, purple lenses: absorb dazzling yellow.Green lens: eyes are not easy to fatigue, suitable for wearing all day.Red lenses: When the light is dark, it can improve the ability to recognize warm colors with the naked eye.Brown lenses: enhancement contrast, inadequate use in the morning, cloudy, and lack of light, keeping the vision clear.Yellow lenses: light increase, make the field of view bright and clear, suitable for the dark situation in the morning, dusk and other light.There are many other colors, which are not described here.
How to use skiing mirrors in myopia
1. Wear a Ski mirror after wearing Contact lenses
Advantages: affordable.Save time and effort.The price of Contact lenses is relatively low. It is recommended that during skiing, we choose daily throw high -transparent oxygen Contact lenses. It does not need to be cleaned and easy to wear.Of course, it is not suitable for wearing Contact lenses for eye redness, swelling, soda, and inflammation.
Disadvantages: poor sanitary conditions and insufficient safety.eyes are easy to swell.During skiing, the weather is often gloomy and windy.Wearing Contact lenses is easy to dirty, it is not convenient to clean and replace, and the Contact lenses are worn inside the snow mirror, affecting the oxygen permeability of the eyes, which can easily cause redness and swelling of the eyes, and severely cause inflammation.When the high -strength exercise or falls, the eyes will bear a certain pressure, and the Contact lenses can be easily pressed out. At this time, can the Contact lenses be worn back, can they find it?Can I clean it?These are hidden dangers.If the Contact lenses are broken in the eyes, it will be even more incapable.
2. Wearing a Ski mirror that can directly "card" Myopia glasses
Advantages: Choose a Ski mirror that is relatively large internal space and directly buckle on Myopia glasses.This is a fairly affordable and effective way.
Disadvantages: The requirements for snow mirrors and Myopia glasses are relatively high, and the center point of myopia lenses is not easy to wear poorly wearing comfort on the pupils.The Ski mirror that can directly "card" Myopia glasses is relatively high in snow mirror. It is mainly designed on the frame and increases production costs.The position of the temples on the left and right sides of the frame generally opens the groove to facilitate the mirror leg of Myopia glasses.Although this kind of snow mirror has large internal space, it is not suitable for all Myopia glasses. Generally, we recommend wearing: memory or TR90 material, good mirror leg flexibility glasses, and myopic glasses use anti -fog lenses. People with small frames are used.This method.
