[UV -proof glasses] How to identify the UV -proof function of Sunglasses, what is the coating

What is UV -proof glasses?

The light emitted in the sun is: visual light, infrared, ultraviolet rays, etc.The ultraviolet rays are seriously harmful to the Skin, eyes, etc. of the human body; the ultraviolet rays in the light released by the sunlight are divided into UVA, UVB, and UVC.It is the light of burning black Skin. Most corners of the eyes will absorb this UVB light, so it is necessary to block this light source.

Because UV glasses have the function of polarizing light, they can block all harmful light without affecting the visual light through, which can truly achieve the function of protecting the eyes.

How to identify the ultraviolet function of Sunglasses

Selecting Sunglasses depends on its lens quality, and pay special attention to the function of Sunglasses.So, how to identify whether Sunglasses have the function of anti -ultraviolet rays?In fact, it is not difficult. Put the Sunglasses on a 100 yuan RMB and use a purple light to identify it.

Experts said that the main role of Sunglasses is to prevent strong light and string light, especially ultraviolet irradiation, which protects eye health in summer and is not damaged.

Therefore, when purchasing, you must pay attention to whether there are "UV400" and "UV" logos on the lens and packaging. At the same time, the UV -proof test is also required.

Method 1. Look at the label of Sunglasses

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

a) Mark the "UV400": This means that the lens's cut -off wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 400nm in the wavelength ()

b) Mark the "UV" and "UV prevention": This means that the lens's deadline for ultraviolet is 380nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 380nm below 380nm;

c) Mark "100%UV absorption": This means that the lens has 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

Method 2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.

Take a banknote, put the Sunglasses on the anti -counterfeit watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.If you can still see the watermark, it means that this pair of sun mirrors are not anti -ultraviolet. If you can't see it, it means that this pair of sun mirrors is anti -ultraviolet.

What is the coating of UV -proof glasses

The most effective and most commonly used method to avoid radiation light caused by damage to the eyes is to wear protective glasses.The so -called protective glasses are a filter that can change through light and spectrum.

This type of glasses is divided into two categories. One is absorption and one is a reflex. The former uses the most.

When the lens is manufactured, a part of the metal oxides are added to the general optical glass formula, such as iron, drilling, chromium, cricket, nickel, manganese, and some rare earth metal oxides such as harmony.

These metal oxides can make the glass selectively absorb the electromagnetic waves in a certain band of light, such as the oxide of the and iron can absorb ultraviolet rays in large quantities.Using this glass lens can reduce the amount of some wavelengths through the lens, reduce or prevent damage to the eye.

1. Absorption filter

Also known as Sunglasses.The transmission rate of visible light is about 20%, and the absorption of ultraviolet and infrared is better.There are many colors such as light green, light gray, and light tea, which are used to make sunshade and snow work protection glasses.

Among them, light gray lenses have minimized color recognition; light tea glasses make the blue sky look darker, which reduces the green light through it; the light green lens reduces red light through.

Second, reflective filter

The absorption filter is absorbed by the lens to some wavelength light to reduce the strong light in the eye, but because the lens absorbs certain light, it becomes heat and release, especially the infrared lines and other waves are longer.The light of light makes the eyes feel uncomfortable due to the accumulation of heat.

In actual work life, many situations are combined with absorption and reflective type, that is, a layer of high reflection membrane is placed on the color lens to make the filtering effect more, such as welding, chlorine -library welding, plasma cutting and other operators.You can use this method to solve it.

[Polarized glasses choose] How to buy Polarized glasses Polarized glasses to buy skills

How to buy Polarized glasses

Sunglasses are like a magic mask. As long as you wear it, you can make you instantly change the same star flavor.Friends who like Sunglasses will have some doubts when choosing a Sunglasses. The current Sunglasses are fashionable and popular in terms of shape, color to material, details.The prices of Sunglasses on the market are available from dozens of yuan to thousands of yuan. What should I choose?Especially the Polarized mirror, I do nt know where to start. Today I will talk about the precautions on the selection of polarizers.

The first consideration is the quality of polarized Sunglasses

The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet penetration. Please choose polarized Sunglasses with the best blocking of UV400 to the best obstruction of ultraviolet logo;The inferior polarization Sunglasses of the polarizing filtering function, such as dark Sunglasses, is darker with the light of the human eye and the pupils of human eyes will become larger, and the ultraviolet rays of the eyes will increase, increasing damage to human eyes.

Will there be discomfort in long -term wear?

Genuine polarized Sunglasses have to be comfortable to wear; if you wear bad feelings such as discomfort, dizziness, headache, dry eyes, tingling, etc.Generally, inferior lenses have no technical and functional at all when manufacturing, and the lens materials are also very inferior. Choosing inferior polarizer Sunglasses cannot protect the eyes. On the contrary, it will cause damage to be worthless.

Select polarizing Sunglasses to focus on the protection function of the frame

In the outdoor sports, it can effectively prevent the stimulation of the eyes and foreign bodies. In addition, the hard level of polarizing lenses and the flexibility of the frame of the frame must be considered whether it will cause damage to the human body.In addition to basic functions such as filtering glare, most polarized motion motion frames are designed with veneer arc.

The identification of the quality of polarized Sunglasses

Generally, regular glasses shops have instruments to detect Sunglasses resisting ultraviolet capacity. Through instrument detection, you can know whether the glasses in your hands have reached the standard.In addition, the simple method of testing the quality of Sunglasses is: you can use the ultraviolet light sent by a banknote test or a banknote check machine to observe the UV logo pattern on the RMB through Sunglasses. If the quality of the Sunglasses is poor and there is no obstruction of the ultraviolet rays, it can still be clearly clear.When you see the UV logo pattern on the RMB, on the contrary, if the quality is excellent, you can't see it.

The selected polarized Sunglasses should be true and natural

The color selection of polarized lenses should be based on the color of the surrounding environment, the edges of the object are clear, and the principle of effectively identifying different color signal Lights.The color of the lens is better in gray, tea, and green, because these colors of lenses are better absorbed by infrared and ultraviolet rays, which can improve visual contrast and clarity, especially when driving Sunglasses, ensure driving safety.It is particularly effective when air pollution is severe or fog.

1. TriviaCycling glassesAdvantages and disadvantages

There are many types of Riding glasses, and the more common one is color -changing glasses.

1. Advantages of color change Cycling glasses

Discounted glasses can change with the changes in ultraviolet and temperature in the environment, thereby protecting our eyes.When riding outside, the eyes are exposed to ultraviolet rays for a long time, which may cause eye diseases. In severe cases, it may also cause eye diseases such as cataracts. Wearing colorful glasses can prevent ultraviolet rays from entering human eyes and prevent glare.eyes are fully protected, providing comfortable visual enjoyment for the eyes.

2. Disadvantages of color -changing Cycling glasses

The price of color -changing Cycling glasses is relatively high, which is mainly caused by people's understanding of color -changing glasses. Due to the large market demand, some pseudo -inferior color change glasses produced by illegal merchants flow into the market.If you protect the eyes, pay attention to purchase through regular channels.

In general, color -changing glasses are more suitable for cycling, but it should be noted that the discoloration effect of discolored glasses will be affected by factors such as ultraviolet strength and high temperature, and it takes time to change color.

2. Is it useful under the strong light of the color changing Cycling glasses?

The color -changing Cycling glasses add silver on the lens, making the original transparent colorless lens under the strong light, and it will become a non -colored lens, which has obvious effects in protecting the health of the eyes.Depending on the principle of the contrast between the light color, it is shot under strong light. The lens is variable color to completely absorb ultraviolet rays.Visible light is neutral.After returning to the dark, the lens will degenerate into the original colorless transparency.

Discounted glasses need sunlight to change color, so even under strong light can play a role, but in the indoor regions, because there is no strong light, it will become the original color.Trimming glasses are especially suitable for Outdoor, indoor strong light and other places, which can prevent the damage caused by sunlight and ultraviolet rays to the eyes.

However, it is important to note that the use of color -changing Cycling glasses is to buy high -quality color -changing Riding glasses. Generally, strong light is required to completely change color within 40 seconds. After leaving the sunThe purchased color -changing Cycling glasses should regularly perform discoloration inspections in the sun. Pay special attention to whether the light sensation of the lens is consistent, so as not to occur in a dark and light condition.

How to choose sports glasses in myopia

1. Incidental lens ordinary sports glasses

This is a solution that most people will choose, because simple, the scope of glasses style is wide, cheap a certain treasure can be bought at tens of yuan, and there are many color lenses for disassembly and replacement.Many, depending on their economic strength.However, the weakness of this scheme is that it is only suitable for short -distance Running, Hiking, cycling and other activities, because if the contact lens is wearing for a long time, it will bring a variety of harms.

Including: 1. For a long time, non -breathable causes hypoxia, unable to metabolize normally, and decreases resistance.And the vision is blurred; 3. Various substances secreted by glasses are deposited on the surface of the lens, breeding pathogenic bacteria, causing corneal edema, corneal new blood vessel reactions and allergic reactions, etc.;Consequences, causing irreversible vision declines; 5. Long -term attachment to the eyeball will paralyze the nerve endings and cause corneal perception to decrease. Many people have unknown ulcerative keratitis;The kind of sour person who has only experienced it will understand.Therefore, for the health of the eyes, and for our exercise, the eyes can be more comfortable, and we should wear as little Contact lenses as much as possible.

Second, the motor glasses of the inner frame close to the box

The advantage of the plan is that the price range is also very wide. A certain treasure can find a lot of options. As low as 100 yuan, high -end brands also have some styles that can be matched with the inner frame.The nearby glasses shop is equipped with myopia lenses, which can choose to match Contact lenses or inner near -view boxes according to the needs.

However, this solution also has a great disadvantage, that is, sports glasses, especially Riding glasses. In order to achieve the windproof effect, it is basically designed as a curved shape that fits the facial facial.This is no problem, but now to be forcibly inserted in the middle, it will cause our eyelashes to sweep around the lens with the blink of an eye.Sometimes with the bumps during exercise, the glasses shake, and the lens will be pasted with our eyelids, leaving sweat or other residues.And because the space between the glasses and the face is reduced, when it is cold or rainy, a layer of water mist will be attached to the lens quickly.All of the above will affect our attention and bring a certain danger to exercise.

Third, myopia sports glasses of plug -in windproof lenses

The principle is very simple, which is equivalent to the first pair of Myopia glasses, and then install a windproof windproof lens in the outer layer, as if the Sunglasses clipped on the Myopia glasses we usually see, but this is the sports version.

Fourth, the degree of swimming mirror ride glasses can clamp the inner frame mirror of myopia lens

In long -distance competitions (such as Ironman70.3 or Ironman Great Rail), players may have to go through long battles. Players have been wearing sports glasses for a few hours during cycling and Running, so the comfort of sports glasses is comfortableIt looks particularly important.Especially the choice of myopia lenses is the key to slowing visual fatigue by long -distance cycling.

Fifth, myopia children can be recorded film shaping mirror

Now myopia is aging, and many young people under 18 have also suffered from myopia, but they also love sports and wore glasses. It is inconvenient.And once wearing frame glasses is broken in exercise, the fragments splash into the eyes or hurt the facial tissue, it is difficult to find and clear.When wearing Contact lenses, you often encounter dust or small particles into the eyes, which can easily cause eye discomfort.In this case, if myopia children want to be easy to be free in exercise, the cornea shaping mirror is the ideal choice.

Patients in myopia can pick the mirror during the day after wearing a corneal shaping mirror at 8-10 hours.Because the lens has a slight compression of the cornea, it will slowly change the shape of the corneal, make the corneal central optical district flat, thereby reducing the number of myopia and astigmatism, increasing naked eye vision, and maintaining the vision all day.

Selection skills of sports myopia mirrors

Generally, I choose sports Myopia glasses to choose a lower degree of originality. The most important thing is to try it in person. There is also a certain windproof function of sports Myopia glasses to avoid wind and sand.Some good sports Myopia glasses will also be equipped with Sunglasses and polarized lenses. This one must choose according to your needs when buying.

It is recommended that the frame must be lightweight. It is not recommended that you use a metal frame. If you do some ball movements, such as basketball football, it is recommended that you choose a silicone wrapper to protect your face.It will be scratched, and the lens can choose a lens type with strong impact resistance or ultraviolet anti -ultraviolet.
