1. How to prevent fog in myopia swimming mirror

The lenses of myopia swimming moster just bought are generally plated with anti -fog layer, but after a period of time, the anti -fog layer is washed away, and the lens appears at mist when swimming, which affects the vision during swimming.Woolen cloth?

1. The most direct way is to buy anti -fog agents, spray or apply it on the lens, and then rinse it with water, but the price of the fog agent is very expensive.

2. You can choose to use baby shampoo instead, the effect is very good, and the price is cheap.How to use: Before swimming, squeeze the baby's shampoo in the palm of your hand, dip it with the index finger of the other hand, and apply it to the lens. Rinse the swimming mirror with water in the swimming pool during the swimming pool.There is no mist on the lens during swimming, nor does it irritate the eyes.

3. Rinse clean water. After drying, drip a few drops of tableware or shower gels, shampoo, do not mix water, let the endoscope be covered (do not rub it with your hand), put it in a lot of decoction, and put it in a few times.Just overnight, then rinse with water to no bubbles.After processing this way, it can generally be controlled for 2-6 hours.

4. Lick the endoscopy with your tongue. It is said that professional athletes do so.The advantage is that it is very convenient to use without cost, and it is not necessary to say the disadvantages.

5. Apply the endoscopic surface with medical Vaselin; or fresh egg white to apply the endoscopic surface, dry it after drying.The disadvantage is that it is easy to accumulate dirt after 1 or 2 months.

2. How to extend myopia swimming mirror anti -fog performance

1. The ultraviolet rays of the sun will destroy the anti -fog performance of the Swimming goggles. Try to avoid placing the swimming moster in the sun.

2. The anti -fog performance of general swimming moster will fail at 80 degrees Celsius.Therefore, you should avoid letting the Swimming goggles contact the thermal source, and avoid placing the Swimming goggles in the storage box irradiated by the sun.

3. The anti -fog performance of the standard swimming moster can be maintained for more than 100 hours. If the mirror surface is found when it is just used, most of the reasons are that the user swims in the unclean or oil -quality water, so that the lens anti -fog surface is attached to a one.Oil stains block the anti -fog effect. At this time, as long as the oil on the lens is washed with a neutral detergent, the anti -fog performance of the swimmog can be restored.

4. Instructions for the use of anti -fog function: Anti -fog agents and anti -fog membranes are all hydrophilic substances. Therefore, when consumers use myopia goggles for the first time, they should be washed with water.Fog performance is fully played.

What kind of material is polarized lens?

The material of the polarizer is two types: resin polarizing mirror and glass polarizer.

1. Advantages of resin polarizing mirror

(1) Light weight.

(2) It is not easy to rupture: In case the lens is crushed, not only has few fragments, but also not sharp, which can minimize the situation of eyeball and facial injuries.

(3) You can dye: Resin lens is easy to dye, and it can be matched with clothing and popularity.

(4) It can cover ultraviolet rays: almost completely covering ultraviolet rays with a wavelength of less than 350mm, and the effect is far better than glass lenses.

(5) Strong anti -fog: Because the thermal conductivity of the resin lenses is lower than that of glass, it is not easy to cause blurred unknown due to steam and hot water and gas, and even if it is blurred, it will quickly retreat.

(6) Anti -dental remarks: Generally, high -heat and small volumes are prone to dental and spots in glass sheets, but if you encounter resin lenses, it will automatically bounce, and will not cause any traces on the surface of the lens.

(7) The surface reflection of the resin lens is lower than that of ordinary glass sheets, and it is not dazzling.

(8) There is no color difference between resin dual -light lenses. This is due to the entire structure of the resin dual -light lens.

(9) The range of resin lens anti -chemicals and solvents is extremely wide. Almost all household solvents and chemicals will not affect or damage it.

2. The disadvantages of resin polarizing mirror

(1) It is easy to abrasrate: The scratch resistance of the resin lens is worse than that of glass lenses, but it can be improved by surface hardening, but the effect is limited.

(2) It is prone to deformation when installing the frame: This is because the density of plastic lenses is lower than that of glass lenses.

(3) Infinitive high temperature: Although the resin is a thermal solid material, once a multi -layer membrane is plated, the surface of the multi -layer membrane may cause cracking due to high temperature.

3. Advantages of glass polarizing mirror

(1) Large hardness: The surface is not easy to be scratched, and it is more abrasion than resin.

(2) Large density: The loading is not deformed, which affects its polarizing effect because it is improper.The density of the resin tablets is smaller, and it is much stronger than the glass sheet. If it is not installed, or the shape of the glasses itself is not very consistent, it will deform, affecting the polarizing effect.

(3) Strong light transmittability: The light transmission of glass sheet is generally stronger than the lipid tablets and stronger clarity.

4. Disadvantages of glass polarizing mirror

(1) Heavy weight: Because its density is more than resin tablets, general glass glasses are heavier than resin glasses.

(2) Fragmentation: As we all know, the glass is fragile.Therefore, its ability to just fight is poor.

(3) Variest prices: The polishing technical requirements for polarizing glass chips are high and the production process is more troublesome, so general glass polarizers are used for mid -to -high -end glasses.

Principles of polarizing mirror

Polarized lens is only allowed to pass through the light of a specific polarized direction in natural light.We all know that light is transmitted in line, which is the particle nature of light; at the same time, light is also spread in the form of waves. This is the volatility of light, so light is also called light wave.Light waves have vibrations in all directions, and polarizing mirrors use the volatility of light.

The core of the polarizing mirror is polarizer, and the polarizing film has a two -way transparent thin film. It allows the light vibration of parallel and light transmittance shafts, and light vertical in this direction is absorbed. This phenomenon is called polarizer of light vibration.change.The light passed through the same vibration direction is called polarized light.The reflection light is absorbed vertically with the light transmittance shaft of the polarized film because the light is reflected.The polarizing mirror uses this principle, which effectively eliminates strong reflected light and scattered light, making the light softer, so that the scenery that people see is naturally clear.The polarizer can also effectively absorb 99%of UVA and UVB to protect the eyes well.It is the first choice for driving, hook fish, skiing, tourism, etc.

But polarizing mirror is not a perspective mirror. When buying polarizers, there will be a test film with some pictures, as long as the Polarized mirror can be seen.In fact, this test film is specially made. It is to use the polarizers to make the polarizer see the parallel light shot from the picture inside, so that you can see the picture hidden inside, not perspective.The method.Now some manufacturers have produced mahjong cards with polarizers, and parallel light images are embedded behind the card. As long as they wear polarizers, they can know what cards are from the back of the card!

How to identify the good or bad of polarized lenses

1. Under normal circumstances, polarizing Sunglasses are affixed with obvious electrostatic electrostatic standards on the lens, or the polarizer lens is marked on the product tag.

2. When buying polarized Sunglasses, you can test it with polarizing test films.Some of the patterns on the test film cannot be recognized with the naked eye, and the polarized lens can be clearly identified.

3. According to the display principle of the LCD screen, observe the liquid crystal screen such as phones through polarized lenses, when the screen is rotated, the screen will also turn into a black screen with rotation.Essence

The advantages and disadvantages of the lens are the decisive factor to measure the quality of a pair of glasses, so consumers must be careful when buying the lens.glass lens is wear -resistant, but relatively speaking, its weight is heavier than other materials, and it is also easy to break.Popular resin lens: This kind of lens is lighter than glass lenses, impact resistance, and is not easy to break, but the hardness is low, so it is easy to get hair and it is easier to have scratches.

What color is good for Telescope lens coating?

Careful friends may find a light color on the lens of your Telescope, especially from a angle. It is even more obvious.Some are blue and some are green.Do you think of this layer of color?The color of the Telescope lens refers to a layer of color with the surface of the eye mirror and object mirror as the surface of the car film. We are also called the lens film.

1. The role of the optical lens film: The physical principle is to destroy the scene observed from the lens under the light of direct light, which causes unreal imaging. In order to enhance the authenticity of the vision, it will be plated on the surface of the eyepiece and the surface of the objective mirror.Movies to increase light transmission, reducing the reflection of eye lens to light is that the observer can receive more light for easy observation.

2. The color classification of the glasses film: there are two types: single -layer membrane and multi -layer membrane.Single -layer membrane can only be used in a relatively simple entry -level Telescope, which can only be used in the light.Multi -layer membrane can increase the light of many bands, which can well eliminate the magnifying bias of the magnifying scene and improve the brightness of observation.Green film is a common multi -layer film, and the more formal green film Telescope in the market.Of course, the red -called infrared membrane is also a multi -layer membrane but most of the market is fakes.

3. What kind of film is good for the Telescope?It is a blue film or a good green film. This is the problem we care about.From the above -mentioned introduction, it can be seen that the green film lens is better than the red film. The red film as a monochrome will look monotonous and boring. After observation, it is easy to feel discomfort and cause eye fatigue.Green film is technically more difficult than the red film. The green membrane will be more comfortable and relaxed, and the transparent band is wider and more broad.

4. Personally think that novice friends can choose cheap blue film Telescope when they buy, because entry -level friends only understand the knowledge and skills of the use of Telescope through it.The quality of the mirror is not so high, and it is more affordable. Try the hand first, and it will be different when you get the good quality.Friends who have higher requirements for Telescope can choose green membrane lenses or even more advanced lenses.

1. What are the differences between night vision glasses and Polarized glasses

1. Different principles

The polarizing mirror is made according to the polarization principle of the light, and the unnecessary light is scattered, such as strong sunlight.

Night vision mirrors are based on the auxiliary observation tools made by the night vision technology at the same time. The night vision technology includes two aspects: micro -light night vision and infrared night vision.

2. Different effects

The special effect of polarizing mirror is to effectively exclude and filter the scattered light in the beam, so that the light can put the eye visual image into the eye transmittance shaft, making the field of view clear and natural.

Micro -light night vision mirrors make the weak light large, so that it shows a clear picture in the sight, so when there is no light at all, the microcomioxid night vision mirror cannot be seen; the active infrared night vision mirror is inIn any case, you can see things. If there is no infrared source, passive infrared night vision mirrors cannot see things.

3. Different use of usage

Polaries can be used when driving, fishing, skiing, rain, etc. are used in strong reflection or strong light.

Night vision mirrors are usually used at night, and they are widely used in the fields of transportation, military and other fields.

2. How to choose night vision glasses

1. Material of the lens

The material of the lens affects the effect of protecting the eyes. You should choose the driving mirror made of polarized lenses. This can effectively reduce the dazzling Lights and the light of the Lights.The strong light becomes soft, and the vision is clearer, which also guarantees the safety of the driver's friends and relieves the fatigue of the eyes.If possible, let the salesperson darkens the light when buying, and feel the softness and clarity of the Lights after wearing the product.

2. The radian of glasses

The comfort of polarizing driver mirrors depends on the arc of glasses.Westerners' nose bridges are generally tall, and the contours of the bridge of our Orientals are round. Therefore, when choosing, you can try it. After wearing it, you can feel that it is easy to drop and hold the nose. It is most important to choose the glasses suitable for us.

3. The nose of glasses

When the driver friends buy the night vision mirror, they should choose the kind of soft and elastic nose. In this way, it will not make the nose of our major drivers feel uncomfortable.

4. Observe the mirror leg

The flexibility of the driver's mirror legs is also very important. Check out whether the mirror legs are flexible and whether the size can be adjusted to meet the needs of different drivers and friends. Flexible mirror legs will be easier to adjust and make drivers feel more comfortable.

5. Framework material

You should choose a driving mirror of the alloy material. The glasses made of this material are very light, the weight is not heavy, and it is strong. The ears will not be uncomfortable because of wearing glasses for a long time.

6. The thickness of the lens

The thickness of the driver's lens lens affects the use of glasses to a certain extent. Choosing glasses with thicker lenses can be more durable to prevent the glasses from being stimulated and unexpectedly crushed, effectively protecting the eyes of drivers and friends.

What is polarized clamp

Everyone may encounter the sunlight when driving, and the eyes are too strong. As we all know, it is well known that if the driver's sight is poor, it is very likely to cause a traffic accident.At this time, you need a good Sunglasses. However, many myopia friends say that wearing Sunglasses is a very difficult thing for yourself. Ordinary Sunglasses are very difficult to load your eyes. myopia Sunglasses vision of the vision of myopia Sunglasses.The correction effect is not satisfactory, so what does this do?I recommend a very convenient product here -Sunglasses.

What is Sunglasses clip

Everyone knows the Sunglasses, but what is the Sunglasses clamp? In fact, it is very simple. The Sunglasses clamping the mirror legs on the basis of Sunglasses, and a clip is added between the two lenses.In this case, myopia friends can use Sunglasses very conveniently, so they don't have to worry about wearing two glasses.

Types of Sunglasses polarizers

The first is color lenses. The most common is pink lenses. It is average in sunlight and ultraviolet filtration. The main advantage is that the price is cheap.Then there are tea colors and gray types. This kind of optical fiber filtration ability is strong, but the price is also more expensive.

Secondly, there are coating lenses. This kind of lens uses coating on the mirror to reflect light to protect the eyes. In addition, this Sunglasses will reflect the rainbow -colored light when wearing, and it looks cool.

There is also a relatively special Sunglasses, yellow Sunglasses, which is generally common in shooting competitions. If you want to observe more clearly, users can consider this yellow Sunglasses.

Six major lenses classification

1. Anti -light protection lens

This lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, making you see things clearer and not disturbed by strong light.To detect whether your Sunglasses really use anti -light protective lenses, you can align the light sources. If you see purple or green reflex, it means that the lens does have anti -reflected protective membranes.

2. color lens

Also known asThe "staining lens" is to add some chemicals during the lens production process to make the lens appear color to absorb the light of a specific wavelength.This is the most commonly used lens type used in Sunglasses.

3. color -painted lens

The effect of this lens presented is the same as that of color lenses. It is only made of different ways. It is to apply color to the surface of the lens. The most well -known is"Gradual -like coloring lenses", the color is the deepest, and then it is lighter.Generally, Sunglasses with a degree of degree are mostly treated with color -coating.

4. Polarized lens

In order to filter the dazzling light in the water surface, land or snow, add vertical special coatings to the lens, which is called polarized lens.It is most suitable for outdoor sports (such as: maritime activities, skiing or fishing).

5. Trimming lenses

Some people call it"Optical lens".Because the chemicals of silver are added to the lens, so that the original transparent and colorless lenses will become colored lenses when encountering strong light, so it is suitable for indoor and Outdoor simultaneous use.

6. Meicoscopy

Poor Sunglasses designed for myopia people are effectively anti -glare and ultraviolet rays.It is especially suitable for outdoor sports such as driving, Outdoor, fishing, etc.Adopting polarized lens technology, the visual resolution is greatly improved.eliminate99%The reflection light and scattered light make your vision clearer and soft.The lens is specially added to enhanced treatment, which is effective, scratch resistance, and impact.

precautions for Polarization of Polaries

Because most of the purchasing Sunglasses clamps are myopia users, it is recommended that you choose yellow Sunglasses as much as possible when buying. This Sunglasses have a small degree of distortion of things. Otherwise, after the distortion of two pairs of glassesThe distance and shape.

1As well asUV prevention function

When we buy an external Sunglasses, we must first confirm whether the purchased product has the function of anti -ultraviolet rays. If there is no ultraviolet function, it is not possible to block the damage to the eyes by ultraviolet rays.Before buying, general merchants will have a banknote test machine or a professional instrument to prevent ultraviolet rays. Testing with instruments is simple and fast.Use the banknote check machine to identify, you can100Yuan's banknotes are placed in the banknote inspection machine, and then the lens is used to block ultraviolet rays to see if there are still anti -counterfeit marks. If the anti -counterfeit mark appears, it is not anti -ultraviolet.

2As well asWhether the external clamp has a polarized effect

The polarizing effect helps us better distinguish the objects under strong light and reflect light, and can improve our visual effects regardless of driving, skiing, or fishing.General external Sunglasses will have this function, but in order to buy a rest assured product, we can use the mall's polarizing test card for testing. GenerallyEffect lens.If there is no polarizing test card, you can also cross the two polarized lenses to overlap and overlap. You cannot see the polarizer of the lens outside the object, and the non -polarized product can be seen.

3As well asOverall structure of external clamps

Many of the tight device on the polarized clamping sheet are iron, which is easy to scratch the lens.When we choose the product, pay attention to the smoothness of the product to avoid scratching our glasses.The force point of contact with the lens requires special attention. Pay attention to whether the contact point of the product is fitted with the lens and whether there is rubber/ /Silicone is separated.Do not choose an external clamping piece of metal products, which can easily cause the lens to scratch and affect vision.

In fact, most Sunglasses manufacturers have made Sunglasses. When choosing, everyone pays attention to choosing the famous Sunglasses brand, such as Tyrannosaurus, Ray Peng, Versace, Buick, Bao Sheng, etc., are all good choices.For more well -known brands of polarizers, please refer totop Ten brand brand Rankings of PolariesEssence

Xiaobian concluded: Although Sunglasses can effectively protect the eyes and play a purpose of playing handsome, it is not suitable for wearing Sunglasses at all times, such as the interesting report, banquet, and wearing Sunglasses at night.Excience, so wearing Sunglasses must also pay attention to time, occasion, working environment, etc.Okay, the introduction of Sunglasses clamps is here. Let's buy Sunglasses folder that suits them.
