[What does polarized Sunglasses mean] The benefits of polarizing Sunglasses are suitable for which Sunglasses are suitable for wearing

What does polarized Sunglasses mean?

Polarized Sunglasses are a Sunglasses.Polarizes can be divided into three types, namely linear polarizers, ellipse polarized and round polarizers.Generally, the so -called polarizer refers to the straight line polarization, also known as flat polarization.The vibration of this light wave is fixed in a specific direction. The transmission route in the space is a sine curve, and the projection on the plane of the vertical dissemination direction is the straight line.

The plane composed of a straight polarized vibration direction and the direction of propagation is called the vibration surface. It is vertically vertically from the vibration direction and the surface of the dissemination direction is called polarizing surface.Make nature light through polarizing mirrors, and can obtain straight -line polarizers, which are often used in crystal optical research.

Benefit of polarized Sunglasses

Generally, Sunglasses only use the effect of reducing light. Because general lenses cannot filter the light, it can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block these harmful light. ThereforeThe biggest advantage of glasses is good popularity.Polarized lenses are dazzling glare caused by various factors such as scattering, folding, and reflection.At the same time, the ultraviolet light that is harmful to the human eye can be completely blocked, so that people's eyes are not tired when they are active under strong light for a long time, and they can achieve the function of true protection, and make the seeing things clearer and three -dimensional.

Which Sunglasses are suitable for driving

1. Must -wear in Sunglasses/polarizer

Sunglasses are very familiar daily necessities. In addition to protecting the eyes in a strong light environment, it is also a decoration that shows individuality. There are many styles.For driving, Sunglasses are even more necessary auxiliary tools. Today we will talk about Sunglasses in the hands of drivers and friends.

For driving, Sunglasses are not just accessories

For driving, wearing Sunglasses is not just to cover the dazzling sunlight, nor is it useful. It is directly related to driving safety. Many friends around me wear Sunglasses when driving, but not everyone will say it.reason.

Seeing the dazzling sunlight will be uncomfortable, and you need to say more about tears, so except that?First of all, when driving, we have to focus on the situation ahead. In addition to the dazzling sunlight in front, there are reflective Lights on the road, reflection of the front windshield, reflective light of the glass walls on both sides, etc. Therefore, if there is no Sunglasses,It is easy to cause eye fatigue. In addition, in the process of switching in the bright and dark environment, it will also be adapted to affect driving safety because it cannot adapt to the safety of driving.

In addition, in addition to the hot summer, it is also necessary to prepare a Sunglasses in winter, especially in snowy weather. The environment in front of the eyes is white. After a long time, you will find that your eyes are very uncomfortable., That is, the "snow blind" phenomenon often mentioned before.

Buy Sunglasses

For friends who have no problem with naked vision, you can choose the style of Sunglasses as one of the things that are very happy. For me who wearing glasses since I was a child, I chose Sunglasses, hey ... you know.Back to the topic, the lenses of Sunglasses are really not simple, there are many types, but there are not many suitable for wear when driving.

Polarized lens Sunglasses -the best choice for driving!

If you plan to buy a Sunglasses you wear when you drive, remember a word: "polarizing mirror", if you are too lazy to understand so much, remember to buy this type of Sunglasses, this is the most suitable Sunglasses that are suitable for driving, Sunglasses wearing when drivingEssence

What is polarizing mirror?

Polarized mirror is a lens that allows directional light to pass through. If a vivid description can be understood as the effect of the shutters, adjust the shutters into a horizontal state.The lens with polarizing function can filter the dazzling glare caused by various factors such as scattered scattering, folding, reflection, etc., and the ultimate effect is to say goodbye to the light and strong light that affects observation, and the light of the overall environment will not be darkened significantly.What you need to observe can be seen really.

In the process of driving, in addition to the dazzling sun in the sky, there will be various dazzling mixed Lights. For example, when we drove east to the east in the morning, the sunlight on the ground was even more dazzling than the sun.Various dazzling Lights reflected by the windshield or chrome decorative strip of the vehicle, and many traffic accidents are also caused by this. After wearing a polarizer, this part of the damaged reflection will be filtered out.In short, Sunglasses with polarizing function are the most suitable Sunglasses for driving.Polarized mirror is more expensive than ordinary ones, but for driving safety, this is worth having.

2. Non -Polarized mirror/clip film

Non -polarized Sunglasses -single function, not recommended

Such Sunglasses that generally do not have polarized lenses are the most common styles, and the price is generally cheaper, but from the perspective of filtering ability, it is not selective.But the dark place is not clear, and it cannot solve the problem of miscellaneous light. For the dedicated driving environment, wearing this Sunglasses will still have a sense of fatigue, and there is a certain hidden danger.Those who have no polarizing function are not recommended to buy.

Moosure with shallow deep and down -cannot protect the eyes in an all -round way

This Sunglasses are also commonly known as "gradient color" Sunglasses, which is more humane than solid Sunglasses, because wearing Sunglasses is to prevent dazzling sunlight.The objects below were cleared, but this type of Sunglasses still insufficient for driving, because when driving the vehicle, the strong light that affects the sight in front of it is not only from the sunlight above.In the back of the car, in this case, the shallow and shallow gradient Sunglasses are not practical.

Adaptive discoloration glasses -basically waste firewood for driving

This kind of color -changing Sunglasses is also very common. The principle of discoloration is simply a chemical reaction of the lens during ultraviolet rays through the lens, which makes the lens darker.It has a stronger ability to adapt to the environment, but there is a detail that needs to be paid attention to. The fatal details are that the windshield glass of most households on the market currently has the function of filtering ultraviolet rays, so ultraviolet rays that promote lens discoloration are ruthless.Filled by the windshield!Therefore, in the car, the discolored Sunglasses will become wastewood. This kind of lens is more suitable for Outdoor, and it is okay to drive.

Drive at night to wear Sunglasses?Are you kidding?

Friends who often drive at night, what do you think about all kinds of high beams?"XXX, XXX, XXXXX", Well, yes, I understand.However, in addition to scolding streets and using anti -glare rearview mirrors, there is also a "Sunglasses" specializing in nights that can help us solve this annoying problem.This kind of glasses cannot actually be counted as the category of Sunglasses. It is a night vision glasses with special filtering strong light. The lens is yellow and easy to recognize. It can reduce the brightness of high -strength light at night.After the strong light is filtered out, the infinite dark areas after "reverse light" will improve.

The price of this type of "Sunglasses" ranges from dozens to hundreds, but according to the frequency of use, it is actually not necessary to spend too much. It is most important to wear it.But it does not exceed 100 yuan.

Don't be crazy when wearing glasses

1.

For friends who usually wear glasses, clamps are the most convenient and most cost -effective solutions. It is also convenient to use it. It can be used on the glasses.View (one more awkward), friends who care about this detail, can choose lighter iron graphic lenses.

At the same time, it will be a little bit short. For example, glasses will be covered with dust and stains after wearing it for a while, and regularly wipe it. I usually rub the two faces of the lens.I am distressed, one of them will not feel transparent after forgetting to rub, switch between the environment with a large temperature difference, and the two groups of lenses are foggy even more.

3. Moosure/storage

2. Invisible lens plus Sunglasses

If you can adapt to wearing Contact lenses, the range of Sunglasses style is very large. From the perspective of convenience, this is the best combination.

3. Moisturizer with number

For friends who have the degree of eyes that are not adapted to Contact lenses, in addition to auxiliary tools such as clamps, you may wish to consider directly equipped with a pair of Sunglasses.The lens must be easy to use. In addition, the price is more expensive than the same Sunglasses and the same Sunglasses.

It should be noted that due to the characteristics of the polishing process, the higher the degree of the lens, the thicker the edges of the lens, so if your eyes are relatively high, it is not recommended to choose a style with a large area of the lens. Although the field of vision is good, it will be laterThe lens will be very heavy, and it will be buried for a long time.

Store

Many car owners like to always have a pair of Sunglasses in the car. This is a good habit, but the storage of Sunglasses also needs to pay attention. It is very likely that it is likely to pay the price.Deformation or even scrap.

In fact, the glasses, no matter where they are placed in the long run, should be placed in the protective cover when not in use, and another glasses cloth inside to prevent lens scratching. In addition, do not put Sunglasses on the center console.Especially in the hot summer, Sunglasses will really deform after being exposed to high temperature, especially plastic frames and resin lenses. Even if there is no problem of deformation in winter, it is a pity to fly out in the bright place.

Summarize:

I admit that in our lives today, it is not just sunscreen tools, but also a Tool for clothing to match and recognize personality. However, for driving, styles can really not be considered as the first needs, safety first.Finally, I emphasized again that if you intend to wear a pair of Sunglasses wearing when you drive, when you walk into the glasses shop, the staff asked what you need, you must say, "I want to see the Sunglasses with polarizing function."
