[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.

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.

3. Check the structure of Sunglasses clamps

If it is not a formal brand, iron device is generally used, which will make the lens easily scratch and even cause damage to the eyes.On the contrary, if we choose a big brand, its quality will also be guaranteed. When the lens is in contact with it, it will avoid the separation of silicone.

[Types of Sunglasses] What are the types of Sunglasses?

What are the types of Sunglasses

When buying Sunglasses, many friends do not know which type of Sunglasses they need, simply pay attention to the ranking of Sunglasses brand, and choose according to their preferences.eyes, you need to take more care, so you should know more when choosing Sunglasses and less blind.What kinds of Sunglasses do you know?Let me introduce you in detail.

The Sunglasses can be roughly divided into the following:

1. Anti -light protection lens

This kind of lens can prevent strong light reflexes, allow you to see things from being disturbed in strong light, and clearer.The principle of this lens is actually very simple, that is, a layer of magnesium is applied on the surface.If you want to know if your Sunglasses are used in anti -light protective lenses, you can align the glasses at the light source. When you see the purple or green reflection, it means that there is a protective film on the lens.

2. color lens

This kind of lens is also called "dyeing lens". The Sunglasses using this lens can absorb the light of a specific wavelength. The principle is to add some chemicals during the lens production process to make the lens appear color.This lens is the most commonly used by Sunglasses.

Third, coloring lens

This kind of lens is actually the same as the color lens, but this kind of lens is generally used in a degree of Sunglasses. Among them, everyone is most familiar with "gradient -like coloring lens". The color is from top to bottom.From deep to shallow.

Fourth, polarized lens

The word polarization is used a lot in Sunglasses, but many people do not understand the specific meaning. In fact, this kind of lens is to filter the dazzling light emitted by the sunlight in an equal direction, and add vertical special coatings to the lens.outdoor sports (such as: maritime activities, skiing or fishing) are very suitable for use.

Five, color change lenses

Another name is "photosensitive lens".Originally transparent and colorless lenses, when encountering strong light, it will become a non -colored lens to protect the eyes. This is because this type of lens is added with silver chemicals.It is very suitable.
