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.

1. Does the myopia swimming mirror hurt your eyes?

Generally speaking, if it is a qualified myopia goggles, it usually does not hurt the eyes.Because the effect of myopia wearing myopia goggles is basically the same with the time when wearing myopia, as long as you can see the water surface when swimming, you usually do not have a bad impact on swimming enthusiasts.If myopia goggles are poor or the number of myopia goggles does not meet its actual degree, it usually causes certain damage to our eyes.

2. How to choose myopia swimming moster

(1) Clear and broad visual experience

1. Selection

If the degree of the wrong myopia swimming moster, dizziness and vague vision will appear, but the degree of goggles that should be selected is not the actual degree of myopia. Because the refractive index of water is higher than that of air, the degree must be compared to the frame glasses worn by the usual frame glasses wearing it.Low.But how much should I choose?The standard provided by ophthalmology experts is:

The degree of Swimming goggles is equal to the number of myopia plus half of the number of astigmatism, and then minus 50 degrees to 100 degrees.For example, if your myopia is 400 degrees and astigmatism is 0 degrees, then the myopia goggles suitable for you are 300 degrees to 350 degrees.In addition, if the degree of myopia is not consistent, the one with a lower degree is prevailing.

2. Look at the performance of preventing fog

The myopia goggles with good anti -fog properties have strong water vapor absorption capacity. Its anti -fog coating contains hydrophilic chemical components, can absorb more water vapor, and use high -tech to prevent anti -fog layers from preventing anti -fog layers from preventing anti -fog layers.Fall off.

3. Look at the field of vision

Generally, the visual field of large size Swimming goggles is wider, but when choosing, it is necessary to consider the degree of fit with the face. This is the second criterion for choosing the goggles: it is comfortable to wear.

(2) Comfortable comfort that is just right

How to judge this myopia goggles for a long time is really appropriate?There is a small trick when trying to wear. Without a mirror strap, the swimming mirror is attached to the face. If you feel a slight adsorption, it means that the Swimming goggles and faces are good.Whether it is perfectly fit, is the length of the nasal bridge just right?

Coupled with the mirror tape to try, determine whether the tightness of the mirror band makes people comfortable, whether the softness of the loop of the eye socket is just right. If it is too hard, it will cause the pain of the eye Bone.The risk of increased intraocular pressure.

(3) Safe and harmless material

The Skin of the eye is very delicate. The mirror zone and the pads are the most frequent parts of the eye Skin, so the material must be safe and harmless.Most of the professional Swimming goggles of well -known brands attach great importance to this point. It uses safe, environmentally friendly, non -toxic high -grade silicone. In order to allow people to leave the face without leaf marks on the face, it also uses liquid silicone.Essence

What is the principle of anti -fog swimming moster

The temperature of the water around the goggles is low, and the local temperature of the people in the domestic people is relatively high. The air in the Swimming goggles is easy to condense on the inner wall of the Swimming goggles to form a tiny water (fog) drip.These small fogs reflect the light to make people's eyes blur.Therefore, the swimming mirror anti -fog is to prevent this fog that can not exist steadily.Now the general method is to modify the surface of the Swimming goggles into super -proof water, so that once the little fog is condensed on the surface of the swimming mirror, it will quickly spread to form a water film. Once the water film is formed, the fog will condense on the water film.(Ball) shape to achieve the effect of anti -fog.

How to choose anti -fog mirror

First of all, the softness and fit of the silicone rings are the most important. You must choose a comfortable silicone ring so that you will not leke your eyes when swimming, and you must be enough to fit the face, so that you will not leak in.

Secondly, it is a lens. The material of the lens of the swimming moster is also very particular. It is best to use the material with anti -strike characteristics. In this way, the lens will not be used for a long time, and the underwater vision is still clear.At the same time, it is best to be light, and the effect of anti -water resistance is better.

As for the choice of the back mirror, of course, it is necessary to adjust. It is suitable for the head shape of different people, and the softness is also very important.

The size of the frame directly determines the size of the field of vision.The big frame has a large field of view, but the mirror of the small frame looks more handsome.

Organic anti -fog mirror classification

1. Anti -fog lens

Stop the fog layer by coating micropores.It can be treated with holes in the mirror surface and glass. Anti -fog coating is generally rich in conductive information A to and silicon oxide.Form a super -proof water anti -static antibacterial agent with inferior anti -dirt, anti -fog, and anti -static effects.

2. Electric heating anti -fog lens

The mirror humidity is increased by electricity.There is no fog.In addition, the mist evaporates quickly.There are other types of anti -fog mirrors on the market.

3. Nano composite anti -fog lens

The nano -glass anti -fog mirror film is combined with physical and chemical phase with the glass.Because water cannot form water droplets on the appearance of the base material, the disposed of glass appearance has hydrophilic function.Instead, a uniform water film is formed to achieve the anti -fog effect.

Classification of inorganic anti -fog mirror

1. PVC-resistance wire anti-fog film

The material is: polyvinyl chloride resistance wire.Features of this membrane: Lead salt stabilizers will be added during production, which are toxic, love heat and soft, hard -to -power, crispy, and easy to get aging.A little break, the entire anti -fog film was scrapped.Advantages: good ductility and electrical insulation performance, convenient materials, cheap prices.The overall service life of this membrane is 4-5 years.

2. pet-resistance wire anti-fog film

The material is: polyester resistor wire.The characteristics of this membrane are: pet membrane surface is Smooth, non -toxic and environmentally friendly, heat -resistant, wear -resistant, corrosion -resistant, anti -aging.The overall service life of this membrane is 8-10 years.

3. pet-carbon fiber anti-fog film

The material is: polyester carbon fiber.The characteristics of this membrane are: cumbersome production process, long construction period, high cost.High toughness, tensile resistance, long service life (more than 20 years), surface -shaped heating body, high temperature resistance, and carried oxidation.Multi -line parallel, even if a certain point breaks, does not affect the anti -fog performance of the entire membrane, the temperature can be appropriately adjusted within a certain range, it is not easy to deform and break, and can be reused.Because of the stability performance and high service life of this film, the renovation of high -end hotels is generally selected for this kind of anti -fog film.However, this carbon fiber -proof fog film, because the selection and processing of materials are complicated, the price of carbon fiber -proof foggy film is relatively high.

Iopia eyes can be wornPolarized sunshine?

Who can understand the pain of myopia?Many friends dare not try polarizing Sunglasses because of myopia.In fact, myopia can wear polarized Sunglasses. Let's take a look at what good methods.

1. Polarized Sunglasses with a degree

A degree of polarizer is suitable for friends with myopia. This is a lens that combines polarized lenses and myopia lenses. It can effectively solve the confusion of myopia friends who cannot wear polarized Sunglasses!

2, glasses clip

You can also buy a pair of Polarized mirror clips suitable for Myopia glasses that are usually worn. This has the same Shading effect as the normal polarizing mirror, and the effect of blocking ultraviolet rays is also very good.

3. Set mirror

Everyone can also buy a large polarized Sunglasses on myopia mirror. Although it is very convenient, it will make your nose bridge to bear the light weight!

Is myopia polarizing mirror harm the eyes?

Under the condition of precision mirror, it will not be harmful to the eyes. Ordinary polarizing mirrors cannot correct myopia. You can customize a pair of polarized mirrors with myopia.However, people with myopia wearing myopia mirror may have a lot of inconvenience, especially the degree of polarizer with a degree of polarizer. It needs to change glasses when using it indoors. It is very troublesome. Thereforemirror.

What are the types of myopia polarizers?

1. Upper flip type

It is convenient to quickly roll up when the light environment is often or rapid, and the safety and convenience are improved to the greatest extent.The Sunglasses can also be removed and used as Myopia glasses alone.

2. Replacement

The innovation of this method is relatively low, but the toughness of the materials is better and the mold is accurate.Friends who do nt travel frequently and have a lower degree can consider. You can bring close -up videos in the room when you go to work. You can switch to Sunglasses when you travel!

3. Uncinction mirror frame

It can be easily disassembled. Because the frame materials are not easy to change, it is very stable.It is currently the best solution to myopia.

When do I need to wear polarized Sunglasses

If you don't drive, you rarely participate in outdoor sports, but if you walk shopping and walk, a Putong Sunglasses can already meet your needs.So when should I wear polarized Sunglasses?

The polarized angle and arc of polarizing Sunglasses are professional design and processing. The wearer will not have the feeling of distortion and dizziness of the scene. It is most suitable for fishing, driving, sports, navigation, skiing, hunting and other occasions.For example, fishermen like to wear polarized Sunglasses, because wearing it fishing, it is easier to see Fish drift and not tired of the eyes.At the same time, polarizing lenses are the most recognized lenses in the world.Polarized tablets make the polarization principle of light, which can effectively eliminate the special functions of glare, filter the disorderly light, make the driver improve the vision, and the driving is easier.Even friends who love Outdoor tourism are unique to polarizing Sunglasses, because it can enhance color contrasts, reduce reflection, enhance the color saturation of the scenery, and let you see a clearer world.

Wearmyopia polarizerWhat to pay attention to

1. Everyone usually controls the time of polarizing Sunglasses and should not be worn for a long time.

2. Do not wear polarized Sunglasses for a long time outdoors, and remove it indoors.

3. Do not choose polarized Sunglasses with too large frame frames and excessive quality. This Sunglasses can make people swell on their faces and distracted their attention.

4. Friends who drive when they encounter a large temperature difference inside and outside the car. When the windows and glasses are fog, they should stop the car safely, and then dry the polarized Sunglasses carefully.

1. What harm can the eyes be suffered during the cycling movement

riding is a good movement, but because it is exercising in the Outdoor sun, if you do not pay attention to protection, not only do you not achieve good exercise effects, but it is easy to hurt yourself, especially the protection of the eyes in the cycling motion.It is very important.Eye damage that may suffer during cycling is:

1. Sunshine

Direct light of strong light will make the eyes unable to open and affect the safety of the cycling; the glare generated by the reflection of the sunlight will also affect the clarity of the sight; the ultraviolet rays and blue light in the sun will cause direct damage to the macular part of the eyes.

2. Wind sand

The wind blowing into the eyes when riding is very strong, especially when the ride speed is faster. In addition to making the eyes difficult to keep it open, it will also make tears quickly and volatilize.Eye fatigue; in the long run, the corneal epidermis of the human body will cause damage, and it will tingle even if it is not cycling.

3, foreign body

During the cycling process, the flying sand, mosquito, rainwater, etc. are foreign objects that are easily invaded into the eyes. Sometimes, even if we put on ride glasses, block the directly impact, sweat, rainwater and other liquids may still flow into the eyes with impurities.Cause stimulation.The human body has no keratin, which is more sensitive than the Skin, and it is easy to induce allergic conjunctivitis. Dry, itching, severe tingling, and tears have more than any symptoms.

It can be seen that if the cycling movement does not pay attention to protection, the danger is ubiquitous, especially in the long -distance ride, so we should pay attention to wearing ride glasses. So what is the use of Cycling glasses?

2. What are the effects of Riding glasses

Riding glasses and riding helmets and magic turban are also called three -piece set of head protection. They are mainly protecting the head. Riding glasses are mainly used to protect the eyes. Its role is:

1. Anti -collision

The toughness of the ride of the glasses is quite good, which can prevent the hitting the eyeballs of the sand and the flyworm.The front car is pressed on the pavement with gravel, which often leads to the flesh of gravel, especially the highway vehicle with high tire pressure and high hardecling hardness.The anti -collision function of the glasses is to prevent this accidental damage.

2. UV prevention

cycling is outdoors. If you don't wear Cycling glasses, you can't open your eyes when the sun is big. This will affect the observation of the road conditions ahead and may cause a series of unsafe factors.With Riding glasses, it can not only shade and sunscreen, but also has anti -ultraviolet function, especially suitable for summer cycling and high altitude ride.

3. Wind -proof

If you do nt wear ride glasses for a long time, your eyes will become very dry, or even red, and very uncomfortable. This is mainly caused by the fast riding speed and the wind blows into the eyes.When high -speed cycling, prevent wind from blowing directly into the eyeball, reduce the impact of the airflow on the eyes, and prevent the wind from invading the eyes in the wind.

The above is the role of Riding glasses. If you want to ride, it is necessary to wear a ride glasses.
