A height that is not steep.

However, if Rice had not worked hard seriously and in a planned and directional manner after establishing her ideals, her words would have only drifted away with the wind. If Andersen hadn't worked tirelessly in the face of difficulties, and if he hadn't persevered in the face of others, he would not have been able to achieve his fairy tale, and he would have ended up just a shoemaker.

A coach of Shichahai Sports School once said: "Our training arrangements are thorough and effective, you will not see any player idle, the old players have experience, they will teach the younger players all kinds of game experience and hitting tactics." "What I think of is to let every element of a team give full play to its advantages, form a virtuous circle within the team, and learn from each other to maximize operational efficiency, which is the strength of the Chinese table tennis team.

System optimization.

Summary. Hello. Kiss! There are several ways to identify the authenticity of Essilor lenses:

I. .Look at the fog display anti-counterfeiting indication of the lens.

Breathe hot air on the lens, so that the lens fogs up to a certain extent, and you can see that the English letter "crizal" on the lens is translated into Chinese as "diamond crystal". Most of Essilor lenses are diamond films, such as Diamond A+, Diamond A3, and Diamond A4.

The first step is to find the *** attached to the lens packaging bag and scrape off the coating with your fingernails.

Fourth, click "Scan Code Products".

The fifth step is to scan the scratched *** on the lens packaging bag, if the following query result is displayed, it is **, if the lens *** has been queried before, or there is no relevant information, it is possible to buy a fake.

On the PC side, Essilor's official ** also has a product verification page, which is very similar to the verification method with WeChat, but it can't use the scanning function, and you need to manually enter the code, so I won't introduce it separately.

Hello. Kiss! There are several ways to identify the authenticity of Essilor lenses:

I. .Look at the fog display anti-counterfeiting mark on the lens to the lens mouth, so that the lens fogs up to a certain extent, you can see that the lens has the English letter "crizal", translated into Chinese is the meaning of "diamond crystal".

On the PC side, Essilor's official ** also has a product verification page, which is very similar to the verification method with WeChat, but it can't use the scanning function, and you need to manually enter the code, so I won't introduce it separately.

Today, let's briefly talk about the analysis of Essilor lens selection.

When to need A4 and when to choose A3

First, the series features:

1. Essilor A+ series: This is the basic model of Essilor.

When introducing his features, in fact, other series include these features, so I won't introduce them later.

UV protection: This is a function of the whole system, not to mention, most lenses have it, and it is not a selling point. Any lens has it.

Waterproof: This function should be said to be that most lenses are belted, mainly with a water-soothing film layer. It is not easy to stick to water droplets.

Abrasion resistance: I think this one needs to be said in particular, it has been tested. Essilor lenses will be a grade higher than ordinary lenses, such as a certain month's hardness, and the wear and tear of a certain month's lenses and Essilor's lenses have been compared.

It was found that the hardness is about the same, and even Essilor's will be more wear-resistant.

Stain resistance: Actually, I don't think the advantages of this are so obvious. It's about his lack of fingerprints.

But if you really have the lenses in your hands, no matter what the lenses are, they have to be wiped clean, and he will just leave fewer fingerprints. It doesn't mean you don't stay. It can be classified as a category that can increase the hardness.

Because reducing the number of wipes can reduce scratches.

Reduce reflections: This effect is still relatively obvious, and the most important thing is to take pictures. When taking pictures, his lenses have minimal reflections. You can think about it another way, less reflection proves that the light will transmit more, so his light transmittance will be better.

3. Essilor A3 series:

The advantages include the above-mentioned waterproof, stain-resistant, abrasion-resistant, reflective and UV-resistant. An extra feature is dust resistance.

On the bright side, they buy the dust-proof function at the price difference.

Dustproof: Many people will misunderstand dustproof as anti-dandruff, but this is actually wrong and may have some effect. If you happen to be oily**, dandruff can stick to the lenses like oil.

This feature is the kind of classic dust resistance, which is less dust absorption, and dry dandruff will also be less. But oily dandruff can't help it.

I often see people asking what to do if the lenses are always dirty, and then a bunch of fools will say that with A3, he has a dustproof effect. It's really uncomfortable to watch. The function of the lenses is not understood in the ** blind call.

4. Essilor A4 series: This lens is an upgraded version of the combination of A3 and A+. He includes all the advantages of the A3 and has an upgrade for blue light resistance.

Selectively filtering harmful blue light is a very big selling point here. Not all of the blue light is harmful, this selective filtering can improve his light transmittance, and the chromatic aberration of blue will be smaller.

But design and art workers still don't use it, because it's still.

There will be color differences. It's just that his color difference will be smaller.

To be honest with you, anti-wear and anti-dust have a certain effect, but if you want to say that there is no dust at all and no grinding, it is false.

The only downside may be ** too. But Essilor is much better than Nikon, Nikon's quality is not much different from Essilor, and Nikon may be slightly better But Nikon's good lenses are much more expensive than Essilor!

To tell you the truth, I use Essilor A4 lenses. This lens can last up to 2 days without wiping, more than 2 days without wiping, dust-proof is to say, I really didn't find how dust-proof, wear-resistant words still need to be studied, this needs time to observe, I am equipped with almost half a year. I feel like that, the same money is not as good as a bright moon, after all, this thing will have to change the lenses in about 3 years.

Anyway, I won't use Essilor's lenses next time because I don't feel like I blow well.

Essilor's lenses are easy to scratch and hard, and the plastic lenses are okay, which is better than Nikon. The anti-wear, dust-proof and the like have a certain effect, the hardness of the high refractive index of the anti-wear index will be better and the wear-resistant, the use and maintenance of the lens will also affect the service life of the lens, the dust-proof general plus nano hair film will have a better effect, the lens will be easier to clean, the fog will be faster, and it will not be easy to hang water droplets.

Nikon lenses are definitely better than Essilor, **not a grade.

What brand of space film is easy to scratch... This is a material characteristic, and Essilor has done a very good job.

If you want to talk about the shortcomings, it is that it is a little more expensive.

Essilor lenses are not bad.

Essilor lenses are more distinctive, and the material used for the lenses is the same as that of astronaut masks. So it's very light, 30% lighter than regular lenses, and at the same time much thinner.

Essilor has five R&D centers around the world, more than 500 researchers, and more than 9,500 patents (including patent pending) to date. From 2011 to 2018, Essilor was named one of the "100 Most Innovative Companies in the World" by Forbes for eight consecutive years"One.

You are myopic, and it is highly myopic combined with astigmatism, with aspherical glasses, the refractive index is above, the lenses are thin, and the clarity is good. Essilor is very good, but very expensive.

Please give the best for adoption, thank you.

Essilor lenses are pretty good.

This type of lens is more distinctive. Its material is used by NASA to make astronaut masks and other aviation supplies. Because it is going to space, it is made very light, 30% lighter than ordinary lenses, and at the same time much thinner.

Essilor lenses are very good, one of the top ten brands in the world.

Of course, you must buy ** Essilor, otherwise the quality cannot be guaranteed.

At present, in Shanghai, there is an online physical store, called Yooface, and there is **Essilor,** which is still relatively affordable.

Essilor is a French brand, the main characteristics of the lens are good hardness, in the imported brand of lenses is relatively cost-effective, and easy to identify, as long as it is the lens of Essilor film, there will be an anti-counterfeiting mark on the film of the lens.

Essilor lenses' full line of sight photochromic lenses and progressive multifocal lenses do very well, but in terms of optical performance and accuracy and wear resistance, Zeiss is better than Essilor, and you can choose Essilor if you want to be cost-effective, and you can choose Zeiss if you pursue quality.

Now the rent of street shops is getting more and more expensive, and the wool is out of the sheep, so it is recommended that you go to an optical store in the office building mode to match, and Essilor lenses seem to be discounted, and if you wear Essilor lenses in a street shop optical store, it seems that they are not discounted.

Such a degree can be matched with a good brand, Essilor, Zeiss can be. If conditions permit, the refractive index and the refractive index can be matched. It depends on the individual's financial base.

If you want to buy Essilor lenses online, it's best to buy them. High sales volume. The goods are real and fake, and they are cheap.

For this kind of power, you can choose a full-frame or a half-frame. Due to the small interpupillary distance, it is better to choose a slightly smaller frame, so that it is light to wear, I hope it can help you.

The quality is good, and it is the same level of lens as the Okasa lens.

Yes, the lenses are as easy to clean as the gunss lenses and are very hard-wearing.

It's the real product.

The fog anti-counterfeiting logo in the line of the visual lens and the cinema lens is exclusive to the barricade, which is manifested as crizal after "blowing" in addition to the line of the cinematic visual lens, because the anti-counterfeiting is a special film layer directly on the line of the scope. There is a dent in the mirror surface, but since the film is not clean, the marking tape is normal. Drop an appropriate amount of alcohol and wipe it off with a flexible keeru's tissue or cloth.

Be careful not to wash the lenses with alcohol to avoid corrosion. ）

Essilor lenses will make the colors more dazzling. Among the self-tinting lenses, Essilor 6th generation is the best lens, and it is also quite expensive. Essilor, one of the world's top three brands, is not comparable, from the color and the speed of early return to change color is very fast, if it is the most sunny time at noon in summer, it will become very deep in less than 2 seconds, because as long as there is ultraviolet rays in the room, it will change color and there is a background color, all color changing tablets have a background color.

Essilor lens functionThe reflective reduction feature makes driving safer and more aesthetically pleasing. The stain resistance function can not be easy to get dirty, and it is very clean without much wiping. The wear-resistant function increases the hardness of the film layer and improves the service life.

The canopy waterproof function can shake off water stains with a slight flick, making it easy to clean. The anti-ultraviolet function can greatly reduce the damage of ultraviolet rays to the eyes, and it is a double layer of protection that reflects ultraviolet rays on the outside and absorbs ultraviolet rays on the inside.
