Excuse me, for glasses frames made of acetate, is the softer the better or the harder the better?

I have been in the glasses business by mistake for ten years, and have been working from a small retailer to a small wholesaler for five years. Recently, I saw someone making publicity on the Internet to deceive people for their own online store, so I thought Stand up and expose it.

The glasses wholesale business is divided into four categories: spectacle lenses, spectacle frames, contact lens lenses, and contact lens solution.

First, contact lens solution has the lowest production cost and the highest overall profit. The production cost is basically the price of the packaging. The solution inside may not be much more expensive than normal saline. Have you ever seen one that costs 40 yuan a bottle? Normal saline? However, this does not include patent fees, testing fees, bribery fees for approval, and advertising fees for promotion.

Therefore, contact lens solution is a huge profit for manufacturers. Once the brand is established, it will be a long-term benefit. If a packaged product has been sold for a long time and the price gradually drops, the manufacturer will stop producing this type of product, change the packaging at will, buy the entire new batch number, and then sell it at a higher price.

In terms of specific profit distribution, manufacturers account for 90% of the profits, wholesalers account for 7%, large retailers account for 3%, and some small retailers account for 1% and even sell them at low prices for the sake of publicity.

There is a little secret, no matter what brand of invisible potion, the basic formula is the same, the difference is very small. Don’t think that there is much essential difference between the product you bought for more than 40 yuan and the product you bought for 4 yuan. Of course, the differences in brand, safety, and very small features also exist objectively, haha.

In addition, the so-called full-function no-rub care solution is basically a lie. It is no-rub under certain conditions, haha.

Except for the original Alcon, all contact lens solutions are not truly rub-free. Of course, in China, as long as you are willing to pay, mineral water can be fully rub-free. care solution.

Haichang's potions and Paul Seening's potions are the worst brands among customers and often have problems. No matter whether they find SHE to endorse them or not, the quality of their products still has not improved much.

Bausch & Lomb’s products are the worst in their price range, but Wei Kang’s price is not bad.

The all-in-one or all-in-one lotions from American Eye Health are good at moisturizing, but the domestic products in Hangzhou have much poorer packaging and lower implementation standards than the products sold in Hong Kong and Japan.

Alcon's liquid sterilization ability is the strongest. The earliest batch used the American original liquid, which is really good, but it is very dry to use, especially in the north.

Shibaco's hydrogen peroxide is the only maintenance solution that can theoretically kill all fungi and bacteria, but it is not only expensive but also troublesome to use.

Weikang products are basic potions with no outstanding functions, but the price and quality are very moderate. It could also be a branded potion that has not had any major accidents so far.

In addition, OEM potions are now beginning to appear, that is, there is no manufacturer, only a brand, and the manufacturer is entrusted with the production, such as Shine, Natural Beauty, Dr. Kang, etc. In theory, you can also create a brand of potion. As long as you have connections and a certain amount of money.

Due to drug import restrictions, the possibility of buying truly imported products in China is zero, so don’t think that it is a real Korean potion just because it says Korean product on the bottle.

As for potions, they have been sold for ten years. In a word, they are expensive for a reason, but they are not worth it at all.

If you really want to protect your eyes, don't use contact lenses.

By the way, comfort fluid, also known as artificial tears, except for the all-purpose product, the functions and ingredients of the other products are basically the same.

2. Contact lens lenses

Contact lens lenses are divided into hard and soft types. Hard contact lens lenses cause the least damage to glasses, but they are expensive for fitting, care and maintenance. It is extremely expensive and generally cannot be produced in China. Generally, the retail price of high-quality American and European hard films is around 4,000 to 8,000 yuan, and the incoming price is around 1,000 to 1,500 yuan. Due to the monopoly system, the channels for obtaining goods are narrow. But as far as I know, there should be many parallel imports smuggled into the country.

The production cost of soft contact lenses is extremely low, and the production cost will never exceed 3 to 5 yuan per piece. This still has to include machine losses and labor costs. I once got contact lenses from the manufacturer that cost 12 yuan each, and the quality was much higher than the mid-range products of Haichang and Weikang, and slightly closer to the mid-range level of Bausch and Lomb.

Of course, in our actual sales, due to brand reasons, manufacturers will not give us the real production price even at all costs, but will pay ten times or dozens of times higher.

Generally, the wholesale price of Haichang's mid-to-low-end products is around 30 to 50 yuan, Wei Kang's is around 32 to 60 yuan, and Bausch and Lomb's prices are relatively high, with a very small difference from the retail price. However, Certain incentives will be given in the form of rebates at the end of the year.

According to my ten years of experience, the quality of Bausch & Lomb’s lenses is indeed good. The only drawback is that they are not easy to wear. Haichang is produced in Danyang, Jiangxi. If you don’t want to buy it, don’t buy it. I’m not looking down on people from that place, but I never use the products produced by people there. I don't think Seeing Paul's products are junk, but the quality is indeed average. Weikon is made in Shanghai. The product is hard and small in diameter. CIBARA products are good, but the price is on the high side. It seems that genuine imported CIVAX is not easy to buy. Johnson & Johnson's products are characterized by being soft, thick, and prone to bacteria. Its daily and monthly disposables are good. If you throw them for more than half a year, you must clean them carefully.

Most of the other brands are OEM or imported from Taiwan and South Korea. There are indeed good products, but there are also many that are unappetizing.

The key to wearing contact lenses is to check whether they can be worn, how much water content can be worn, what is the diameter, how big is the base arc, and the maximum daily wearing time. In foreign countries, a doctor must issue a prescription and a wearing certificate. , you can purchase it, and you must go to the doctor for regular check-ups. That's all in China. Human life and dignity are child's play.

If you can avoid wearing contact lenses, then don’t wear them. Apart from everything else, with the climate and dust in China, you shouldn’t wear them. After wearing it, I can tell whether you will have major problems or not, but minor problems, haha. I've seen too many, so I won't talk about some of them. Especially in the south, it's not uncommon for fungi to cause perforations.

But these days, girls can even show off their underwear for the sake of beauty, let alone risk wearing contact lenses.

If you go to an optical shop, they will basically recommend you to wear the contact lenses sold by their store. For example, Baodao will definitely let you wear Haichang or Bausch & Lomb. In order to sell them at a high price, their contact lenses Chang XXX, you can't buy it anywhere else, because it is specially produced for their store, of course it refers to the packaging. If it is a small store, they will usually sell you so-called Korean goods. The quality of this kind of goods is not bad. You can try it, but it is unstable because this month's goods may be produced by Haichang factory, and next month's goods may be from Haichang factory. It may be produced by Weikang Factory. When selling, be sure to check that it is a product with a similar batch number. In most cases, if you feel uncomfortable wearing it, the manufacturer will definitely replace it for you free of charge. Because of this product, merchants’ profits are as high as 60 to 90, and they don’t lose money even if they change several times.

3. Spectacle lenses

Spectacle lenses are divided into two types: glass and resin.

The wholesale price of ordinary white glass lenses is generally around 1 yuan per payment. The price of adding film is 5 yuan. Now due to the smaller production volume, the price of some glass sheets has been slightly increased, and it should be less than 15 yuan. The price of some high-end glass lenses such as 1.90 refractive index is still very high, but there are very few domestically produced ones and they are generally imported.

The wholesale price of ordinary white resin sheets is generally around 4 yuan, the price of coated 1.56 ultra-thin resin sheets is between 7 and 15 yuan, and the price of aspherical lenses is around 10 yuan to 25 yuan. Some brands The price may be slightly higher.

The price of the film basically has nothing to do with whether it is green film, blue film or yellow film. Some places will use the film layer to make some small articles and sell it for a few yuan more.

1.61 pieces are basically around 50 yuan, 1.67 pieces are around 130 yuan, and 1.74 pieces are around 500 yuan.

Domestic progressive films are basically around 60 yuan, while those from big brands are slightly more expensive. Color-changing resin films are around 70 yuan, and even lower if you buy them in large quantities.

The dyed film without film is 7 yuan, and the film with film is 18 yuan.

Astigmatism lenses generally cost no extra money. Astigmatism lenses above 200 degrees cost 5 yuan, lenses above 800 degrees cost 5 yuan, and lenses above 1000 degrees cost more.

Customized lenses may be more expensive.

In addition, do not buy UV400-resistant resin sheets. They usually add phosphor powder inside. They appear to be impermeable to ultraviolet rays. In fact, they block light, which not only affects your eyesight, but also causes harmful effects when encountering strong light at night. Unable to see clearly, the female owner of our wholesale market crashed her car because of this.

In addition, resin lenses themselves do not absorb ultraviolet rays, so resin lenses must be coated with coatings. However, so far, no lenses that truly block all ultraviolet rays have been released. The so-called radiation-proof lenses are basically a joke. If you breathe on the lenses or put some water on them, they will prevent them. They are just a lie to children.

No matter what kind of diamond crystal or carbon crystal, including Essilor, the resin sheet base is inherently soft, so it has little effect, and it is not much different from cheating. Just to have a buying point so I can cheat your money.

The key to your lenses is maintenance. If you maintain them well, they can last for 2 years. If they are not maintained well, your vision will be affected in one year and they should be replaced.

All resin lenses must be tested when they leave the factory. A-grade products are basically exported abroad. At present, the world’s resin spectacle lenses are basically processed by our country, because this kind of factory is not environmentally friendly and is not used abroad. Due to restrictions and high costs, they ship raw materials to the country, process them and then export them, including all major brands.

B-level products are generally sold domestically, with different packaging, and after spending money to buy a license, they can be sold as lenses of different grades. The advantage of this is that the same thing can be sold at different prices in different stores. For example, the Wanxin lens you bought in store A has the trademark "Blue Sand" and a W will appear on the lens when you breathe in it. It's the real thing, I'll sell it to you for 600.

When I arrived at store B, I saw the same Wanxin film with the trademark Asadi. A D appeared on the lens as soon as I breathed in. It must be the real thing. It is better than Blue Sand. It will cost you 800.

As for the gas mark, it is too simple. It uses an electrolyte to generate a strong charge and breaks down one or two layers of the coated lens through a wire mesh. formed. I once made a silk screen with the logo SB, and then spent 30 cents each to print some mirror bags with Sabel printed on them, and marked the most trashy C-level films with this logo. Guess what, Sabel tablets are very popular in our province, and you pay 180 yuan without any bargaining.

Of course you all understand what SB means, but I don’t know if you have ever been a SB. I was one before I entered this industry by mistake.

This equipment only costs 500 yuan, and basically every wholesaler has it. Nowadays, big manufacturers like Wanxin directly distribute the labels and bags. Whatever labels you put on them are the pieces, and the retailers can get whatever they like.

Now, retailers with larger sales understand this. They have their own marking devices, and then print some mirror bags. When promoting, they say, if they find that the price of goods in our store is higher than that of other stores, Compensation of 20,000 yuan. Even if it is a lie, the lenses in his store cannot be purchased anywhere in the world.

Of course there are good and bad spectacle lenses. If you have money, of course you should buy Zeiss lenses, especially Zeiss glass lenses. It takes 25 days to order a pair and have them sent to Germany for processing and then sent back. It is definitely good. Note that it must be sent to Germany for processing. Why? First, in China, the lenses will basically be replaced. The prices of high-end lenses such as Zeiss and original Yiyilu are all public. The profit of the retailer is very small, 100%. Even if it’s less than 50%, no matter how hard it is to take the risk, if you sell any high-end domestic film, the profit will be over 95%. Why bother, so you have to change it. Didn’t I say it before? The bigger the store, the more likely it is that the store will cheat you. If it’s marked, anyone can cheat. You, an ordinary consumer, why do you think it’s fake? What about Zeiss. Identification? Do you know what the relationship is between us and the buddies from the Measurement Division of the Bureau of Technical Supervision? At least we have done some work together. You will definitely lose. Among us who open an optical shop, none of us have a net worth of hundreds of thousands, and you are trying to cut off my money, can you win?

Second, you must understand the most basic truth. Whether glasses are comfortable or not depends on the quality of the lenses themselves. Ninety percent depends on the level of the optometrist. Nine percent depends on the skill of the lens maker.

The most important thing about a qualified optometrist is not academic qualifications, but experience. I have a bachelor's degree, and I ranked first in the city in the theoretical assessment in my first year in the industry. In practice, my retinoscopy and optometry were pretty good, but to this day, I still make mistakes. This is a process of accumulation of experience. Without testing thousands of glasses, do you dare to say that you are a real optometrist? I think you can buy an optometrist certificate for 1,900 yuan, haha. Come on, aren’t the Chinese people all boasting? I am still an intermediate optometrist, and those who have just entered the industry basically buy a senior optometrist certificate. Why not just add another 800 yuan? Why not just buy a high-end certificate.

It takes at least 45 minutes for a qualified optometrist to calibrate the light for an ordinary customer with myopia and astigmatism, and even several days if there are complicated situations. But which eye hospital doctor will spend so much time on you? I have seen many people who go to the eye hospital and have a mirror after the optometry test. The reason is computer optometry.

Is computer refraction accurate? Sometimes it is, but rarely.

The only feasible objective measurement method so far is retinoscopy, and others such as computerized refraction can only be used as assistants.

There are also disadvantages. There are hundreds of millions of people in China who are myopic, but how many optometrists are proficient in retinoscopy technology? Haha, so I dare to assert that the vast majority of myopic Chinese people may not know the truth about their vision accurately until they die.

Looking at the fact that many students’ scores have risen step by step from 1 or 2 Baidu to 6 or 7 Baidu, it is not only related to the current academic focus, but also has a lot to do with inaccurate optometry results and unreasonable lens manufacturing.

The same pair of lenses, the same optometry result, but different opticians use different tools to make them, the results are completely different.

Nowadays, large stores use fully automatic machines that do not require molds and are molded in one piece. The production accuracy can basically meet the needs of users.

Most mid-range stores use fully automatic machines with manual templates. The ones made in Japan are okay, but the ones made in China basically have a running axis and asymmetrical left and right, and the lenses they make are not accurate. I’m not sure whether I’m negative or not, let’s touch it.

As for the lenses made by small shops using handmade wheels and pliers, don’t even think about it. It would be weird to think about it accurately. Someone said that the shop is nice. I have been doing it for many years and it is quite comfortable.

Did you know that the human eye is the most adaptable organ in the human body? Your eyes have adapted to his glasses, haha.

Everything in a big store is expensive. There is a reason why it is expensive. If you want to be accurate, then pay ten times as much.

If you want to be accurate, especially if you have astigmatism, you must choose a half-frame brushed mirror, because it is formed in one piece, which can ensure that there is no error. The holes need to be assembled by hand, which is easy to deviate. The entire frame often also needs to be manually polished, and there is a possibility of errors.

4. Now let’s talk about glasses frames

Glasses frames are very simple to say, but not easy to make. They still require some simple bench tools, and they should be assembled. It is a labor-intensive industry, very labor-intensive, because not only labor is cheap in Jiangsu and Zhejiang, but it is also close to Shanghai, making it easy to export, so the spectacle frame manufacturers are basically located in Danyang. Some manufacturers are near Guangzhou.

Sunglasses manufacturers are basically located in Duqiao, Taizhou, Fujian.

No matter whether this manufacturer or brand boasts that it is international or Shanghai-based, it basically registers a small store in the local area and commissions processing in the above-mentioned areas or simply OEMs.

The materials of eyeglass frames are divided into two categories: metal and plastic. The early eyeglass frames were basically made of copper alloys with high lead and tin content. The cost at that time was very low. I remember I had just entered the industry. That year (1998) I bought a frame for 80 cents in Danyang. The retail price at that time was about 45 yuan. Because lead is very harmful to people and copper is too expensive, Monal alloy is now used. This alloy was developed abroad. It is actually a copper-nickel alloy and is not easy to rust. At first we imported this kind of alloy wire, and then we copied it. However, the Chinese people have a long-standing problem of cutting corners and the lead content is still excessive. If people wear metal-rimmed glasses, if they don’t pay attention to cleaning them regularly, the heavy metals on the frames will be harmful to the facial skin. As a result, the blood throughout the body poses a serious threat. I bet that no Chinese man who wears glasses for a long time has a smooth face.

You may want to say that if I have money, I will make titanium alloys, or even pure titanium.

But do you know about titanium? The level of highly pure titanium refining technology is extremely high. Only the United States, Japan and Russia in the world have the ability to purify nearly 100% titanium. Really high-purity titanium is so expensive. Not only does our country only have one larger titanium mine in Baoji, but our country can only Refined into sponge titanium. Therefore, it can be concluded that the so-called pure titanium frames you buy on the market, except for some purely imported or extremely expensive ones (which may also be fake), are not truly pure titanium.

So what are the impurities in the impure titanium? Halo is the radioactive elements thorium and tantalum. Although the amount is small, wearing it for a long time will cause radiation to the head at close range. I think this impact may be more important than lead.

Titanium and copper are not good, so use new materials: aluminum alloy and stainless steel.

The so-called aluminum-magnesium alloy is actually aluminum alloy. If you have ever ridden this kind of bicycle, it is the same. The advantage is that it is lighter and less susceptible to corrosion, but the disadvantage is that aluminum is a major culprit in Alzheimer's disease.

Stainless steel is good, but the same question is, which stainless steel do you use, real food grade stainless steel or industrial grade stainless steel? People who have worn stainless steel frames, do you think you are wearing imported Japanese ones? Stainless steel? Are there few impurities and radioactive elements in industrial stainless steel?

No matter how good the material is, after the surface is spray-painted and baked, the paint layer itself will cause serious damage to the surface of the skin and long-term penetration into the body.

Therefore, I responsibly tell you that the temples should not be made of metal.

Looking back, is it okay to use plastic (so-called plates) for the temples? In fact, it is entirely possible to make something like plastic non-toxic, but are the ones you use non-toxic? I have no idea.

Now it seems that those made of bamboo or sandalwood may be more environmentally friendly and healthier, but if you wear them for a short time, they will easily change color and crack due to sweat.

Template legs made of calfskin or salmon skin are also available on the market. They are not only expensive, but also do not absorb sweat, heat and are slippery.

A friend said that I am rich and use tortoiseshell turtles. Don’t be stupid. Not only are these turtles in the South China Sea endangered, but they are also national second-level protected animals. If JS insists that this is true, you can Report him directly for poaching and selling wild animals protected by the country, and the reward the country will give you should be much larger than that fake mirror.

Of course, there are also those made of platinum, those made of gold, and heavy. Spending money to find trouble is the favorite of the Chinese who are suddenly rich.

So, is there no temple material that is completely harmless to the human body and can be cheap, light, tough, not easily damaged, and easy to mass-produce? The fact is that we cannot have both. . You can only choose according to your own consumption level.

Generally speaking, plate frames are divided into two categories: lightweight plastic injection molding and hard plastic plate cutting and molding. The wholesale price of the former (the price I sell for takeout) is about 3 to 10 yuan, and the latter The wholesale price is about 15 to 50 yuan. This refers to mainstream styles, and old models that are on sale may be even cheaper.

The wholesale price of metal Monal alloy frames ranges from 4 yuan to 30 yuan, stainless steel frames range from 15 yuan to 50 yuan, titanium alloy frames generally cost around 40 yuan, pure titanium Frames range from about 60 to 150 yuan. Tortoiseshell frames generally range from 300 yuan to 800 yuan. The above prices will vary depending on the brand and origin, style and weight, but the production cost is basically the same.

Some friends will ask why a certain brand sells for several thousand yuan. The reason is very simple. For the same model of sports shoes produced by the same factory, there is at least a difference in price between those with a hook and those without. At 10 times the price, your willingness to spend 10 times more money is your own vanity choice and has nothing to do with anyone else.

Of course, brand products have their own advantages, that is, they can lead the trend. They pass the design styles to the OEM factories. The factories dare not imitate them immediately. The factories usually produce them again after a few months. The same frames of your own brand, so that the brand's products can completely dominate the market. This is similar to the clothing market, where I dare not judge.

How about it. Thank me. So even if you go to a big store to get glasses, don’t spend more than 300. Anything more than that is a waste.
