Problems in Haichang Aishibo Contact Lens Care Solution

I have been in the glasses business for ten years, and I have been a small retailer and wholesaler for five years. Recently, I saw someone cheating for their own online shop, so I wanted to stand up and expose it.

Glasses wholesale stores are divided into four categories: glasses, glasses frames, contact lenses and contact lens potions.

First, the production cost of contact lens liquid medicine is the lowest, and the overall profit is the largest. The production cost is basically the price of the package, and the liquid medicine inside may not be much more expensive than normal saline. Have you ever seen a bottle of physiological saline for 40 yuan? But this does not include patent fees, testing fees, bribery fees at the time of approval, and advertising fees at the time of promotion.

Therefore, contact lens liquid medicine is a profit for manufacturers, and once the brand is established, it will benefit for a long time. If a packaged product is sold for a long time and the price drops gradually, the manufacturer will stop producing this kind of product, change the packaging casually, buy out the whole new batch number and sell it at a high price.

In terms of specific profit distribution, manufacturers account for 90% of profits, wholesalers account for 7%, large retailers account for 3%, and some small retailers account for 1 or even sell at fair prices, so as to promote publicity.

There is a little secret, no matter what brand of invisible potion, the basic formula is the same, with little difference. Don't think that the product you spent more than 40 yuan on is essentially different from the product you spent 4 yuan on. Of course, the differences in brand, safety and subtle characteristics also exist objectively, hehe.

In addition, the so-called full-function rubbing-free nursing liquid is basically a lie, and it is conditionally rubbing-free, hehe.

Except for the original Alcon, all contact lens lotions can't really be wiped-free. Of course, in China, as long as you are willing to pay for it, mineral water can also be turned into a full-featured care solution without rubbing.

Haichang's potion, Bao Shi Ning's potion, is the worst brand of customers and often has problems. Whether it finds her endorsement or not, the quality of the product has not been greatly improved.

The products of Doctor Li and Lomb are the worst in its price range, and Weikang is ok.

American eye-catching all-purpose or all-purpose potions have good moisture retention, but compared with the products sold in Hong Kong and Japan, the packaging of domestic products in Hangzhou is much worse and the implementation standards are lower.

Alcon in the United States has the strongest sterilization ability. The first batch used American original liquid, which was really good, but it was very dry, especially in the north.

Shikang'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 the most important potions, which have no outstanding functions, but the price and quality are moderate. It may also be that a brand of potions has not had a major accident so far.

In addition, there are brand potions now, that is, there are no manufacturers, only brands, which are commissioned by manufacturers, such as Shiny, Natural Beauty and Dr. Kang. Theoretically, you can also create a brand of potions, as long as you have contacts and certain funds.

Due to the restrictions on drug import, it is impossible to buy real imported products in China, so don't think that the bottle is a real Korean potion just because it is printed with Korean goods.

For liquid medicine, it has been sold for ten years. In a word, it is really expensive, but it is not worth it at all.

Don't use contact lenses if you really want to protect your eyes.

By the way, comfort liquid, that is, artificial tears, has basically the same functions and components except all-round products.

Second, contact lenses.

Contact lenses can be divided into hard lenses and soft lenses. Hard contact lenses do the least harm to glasses, but the cost of trying on and maintaining them is extremely expensive, so it is generally impossible to produce them in China. Generally, the retail price of good quality hard lenses in the United States and Europe is around 4,000 to 8,000 yuan, and the purchase price is around 1 1,000 yuan to 1, 500 yuan. Because of the monopoly system, the channels for obtaining goods are narrow. But as far as I know, there should be a lot of smuggled parallel imports.

The production cost of soft contact lenses is extremely low, and the production cost of each lens will never exceed 3 to 5 yuan, depending on the machine loss and labor cost. I once took 12 yuan contact lenses from the manufacturer, and the quality is much higher than the mid-range products of Haichang and Weikang, and slightly close to the mid-range level of Dr. Lee & Lomb. Of course, in our actual sales, due to brand reasons, even if the manufacturer is killed, it will not give us the real production price, but it will be ten times and dozens of times higher.

Under normal circumstances, the wholesale price of low-end products of Haichang is around 30 to 50 yuan, and that of Weikang is around 32 to 60 yuan. The price of Dr. Lee Lomb is relatively dead, which is close to the retail price, but some encouragement will be given in the form of rebate at the end of the year.

According to my ten years' experience, the quality of Dr. Lee Lomb's lenses is really good, but the disadvantages are good and bad, and they are not easy to wear. Haichang is produced in Danyang, Jiangsu. Don't buy it, don't buy it. I don't look down on people there, but I never use products made by people there myself. I don't think Bao Shining's products are rubbish, but the quality is really average. Weikang is made in Shanghai. The product is hard and small in diameter. Vision's products are good and the price is high. It seems that it is not easy to buy the prospect of real import. Johnson & Johnson's products are soft and thick and easy to breed bacteria. Its sun and moon throws are good, and it must be carefully cleaned after half a year.

Most other brands are OEM or imported from Taiwan Province Province and South Korea. There are really good products in it, but there are also many that are disgusting.

The key to wearing contact lenses is to check whether you can wear them, how much water you can wear, how big the diameter is, how big the base arc is, and the longest time you can wear them every day. In foreign countries, you can only buy it with a doctor's prescription and proof of wearing, and you must go to the doctor for re-examination regularly. China, that's it. Human life and dignity are child's play.

If you don't wear contact lenses, you shouldn't, regardless of everything, because of the climate and dust in China. After wearing it, I can conclude that you will have a big problem, but you will have many small problems, hehe. I've seen too much, so I won't talk about some remnants, especially in the south. It is not uncommon for fungi to cause perforation.

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

If you go to an optical shop, he will basically recommend you to wear the contact lenses sold by their shopkeeper. For example, Bao Dao will definitely let you wear Haichang or Doctor Lomb. In order to sell them at a high price, you can't buy their Haichang XXX anywhere else, because it is specially produced for their store, which means packaging, of course. If a small shop sells you so-called Korean goods, the quality of the goods is ok, you can try it, but it is unstable, because the goods may be made by Haichang Factory this month and Weikang Factory next month. When you sell it, you must see clearly that it is a similar batch number. In most cases, if you feel uncomfortable, the manufacturer will definitely replace it for you free of charge. Because of this product, the profit of the merchant is as high as 60 to 90, and you don't have to pay for it.

Third, glasses.

Glass is divided into glass and resin.

The wholesale price of pure white glass sheets is generally around 1 yuan, and coated glass sheets are in 5 yuan. Now, due to the decrease in output, the price of some glass plates is slightly raised to 15 yuan. Some high-grade glass lenses, such as 1.90 refractive index, are still very expensive, but few are made in China and are generally imported.

The wholesale price of ordinary white resin film is generally around 4 yuan, the price of ultra-thin resin film of 1.56 is between 7- 15 yuan, the price of aspherical lens is around 10 yuan -25 yuan, and the prices of some brands may be slightly higher.

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

1.6 1 is basically around 50 yuan, 1.67 is around 130 yuan, and 1.74 is around 500 yuan.

Domestic progressive films are basically around 60 yuan, and big brands are a little more expensive.

The price of color-changing resin sheets is around 70 yuan, and it is even lower if you take them in large quantities.

7 yuan, where the dyed piece is not pasted, the paste is 18 yuan.

Astigmatism tablets are generally free. There are more astigmatism films above 200 degrees in 5 yuan, more astigmatism films above 800 degrees in 5 yuan, and lenses above 1000 degrees are more expensive.

Custom lenses may be more expensive.

In addition, don't buy UV-proof 400 resin sheets. Generally, fluorescent powder is added inside, and the surface is opaque to ultraviolet rays. In fact, it is blocking light, which not only affects vision, but also can't see clearly under strong light at night. So, our female boss in the same wholesale market crashed her car.

In addition, the resin lens itself does not absorb ultraviolet rays, so it is necessary to add a film on the resin lens, but so far there is no lens that really blocks all ultraviolet rays. The so-called radiation protection lenses are basically jokes. If you breathe or dip some water into the lens, you will stop them and cheat the children.

No matter what kind of diamond crystal and carbon crystal are blown, including Essilor, because the resin substrate is inherently soft and has little effect, which is not much different from cheating. Just to have a buying point to cheat your money.

The key to your lens is maintenance. If it is well maintained, it can be used for 2 years. If the maintenance is not good, it will affect the vision after one year and should be replaced.

All resin lenses have to be tested before leaving the factory, and the A-grade products have basically gone abroad. At present, all the resin lenses in the world are basically processed in our country. Because this kind of factory is not conducive to environmental protection and is restricted abroad, the cost is high, so they transport the raw materials to China and export them after processing, including all the big brands.

B-class products are generally sold in China, put on different packaging and spend money to buy a license plate, which 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 brand of Wanxin film you bought in a store is Lansha, and a W appears as soon as you inhale in the lens. The real thing, 600 for you.

When I arrived at store B, the same Wanxin film, the trademark is Asadi, and a D appeared on the lens in one breath. The real thing, better than Lansha, sells you 800 yuan.

As for air breathing marks, it is too simple, that is, using electrolyte to generate strong charges, through a screen, the coated lens film is decomposed into one or two layers, and it is formed. I once made a screen with SB logo, and then printed some mirror bags with Sabel at 30 cents each, and marked the most rubbish C-rated films with this logo. Guess what, Sabel films are very popular in our province, and each 180 yuan is not counter-offer.

Of course, you all know what SB means, but I don't know if you have ever been an SB. Before I entered the business, I was.

This equipment is only 500 yuan, which is basically available in every wholesaler. At present, large manufacturers like Wanxin directly issue labels and bags, and whatever labels you attach is what retailers like.

Up to now, retailers with large sales have understood this. They have their own marking machine, print some mirror bags, and advertise that if we find that the price of our goods is higher than that of other stores, we will pay 20 thousand. Even if it is a lie, the lenses in his shop can't be bought all over the world.

Of course, there are good and bad glasses. If you want money, you must buy Zeiss glasses, especially Zeiss glass glasses. It takes 25 days to order a pair for them to send to Germany for processing and then send it back. I'm sure it will be fine. Please note that it must be sent to Germany for processing. Why? First, it will basically be replaced in China. The more high-end lenses, such as Zeiss and the original factory Yiyi Road, the more open the price, and the retailer's profit is very small, less than 50%. If you are not afraid of trouble and take risks, the profit will be above 95%. Why, so it must be changed? Didn't I tell you that the more big stores bully them, the more they lie to you. If it is marked, anyone can type it. You are an ordinary consumer, why do you say it's fake Zeiss? Identification? Do you know our relationship with our buddies in the Metrology Department of the Technical Supervision Bureau? At least, we made goods together. You are sure to lose. We run an optical shop. Who doesn't have hundreds of thousands of net worth? You still want to break up with me. Can you win?

Second, you have to understand the most basic truth. Glasses are uncomfortable to wear. The quality of glasses only accounts for 1%, 90% depends on the level of optometrists, and the other 9% depends on the skills of optometrists.

For a qualified optometrist, what matters is not education, but experience. I have a bachelor's degree, and in my first year, I ranked first in the city in theoretical assessment. In practice, optometry is also good, but until today, I still made a mistake. This is a process of experience accumulation. Do you dare to call yourself a real optometrist without thousands of glasses? I think 1900 yuan can buy an optometrist's license, hehe. Come on, people in China are bragging. I am still an intermediate optometrist, and basically all the beginners have bought a senior optometrist's license. Isn't it just 800 yuan? Why not just buy an advanced certificate?

It takes at least 45 minutes for a qualified optometrist to calibrate the light for a customer with common myopia and astigmatism, and even several days if it is complicated. But which doctor in the eye hospital will spend so much time on you? I've seen many people feel uncomfortable just making a mirror after examination in an eye hospital. The reason is computer optometry.

Computer optometry is accurate, sometimes, but rarely.

So far, the only feasible objective measurement method is retinoscopy, and others such as computer optometry can only be used as an aid.

There are also shortcomings. There are hundreds of millions of people in China who are nearsighted, but how many optometrists are skilled in optometry? Hehe, so I dare to assert that the vast majority of nearsighted people in China may not know the truth of their eyesight accurately until their death.

Seeing that many students are now rising from "120 Baidu" to "67 Baidu" step by step, in addition to the current academic pressure, it is definitely related to inaccurate optometry results and unreasonable lens production.

The same pair of lenses, the same optometry results, different lens makers use different tools to make, and the effect is completely different.

At present, all supermarkets are full-automatic machines without molds, and the production accuracy can basically meet the needs of users.

Most mid-range stores use fully automatic machines to make manual templates. Japanese products are ok, and domestic products basically have the phenomenon of running axis and left-right asymmetry. The lenses made are not negative or uncertain. Feel it.

As for the lenses made of handwheels and pliers in the shop, don't think about it. It's strange to think about it. Some people say that this shop is good. I've been doing it for many years, and it's quite comfortable.

Do you know that the human eye is the most regulating organ in the human body? Your eyes have adapted to his glasses, hehe.

Big stores are expensive and expensive. If you want to be accurate, how much is ten times?

If you want to be accurate, especially if there is astigmatism, you must choose a mirror with half-frame drawing, because it is integrally formed and can guarantee that there is no error at all. Punching needs manual assembly, which is easy to deviate, and the whole frame often needs manual edge grinding, which is likely to make mistakes.

Fourth, now let's talk about glasses frames.

The spectacle frame is simple to say, but not easy to do. It still needs some simple fitter tools, and assembly should be a labor-intensive industry, which is very labor-intensive. Because Jiangsu and Zhejiang are not only cheap, but also close to Shanghai and easy to export, the manufacturers of spectacle frames are basically in Danyang. Some manufacturers are near Guangzhou.

Sunglasses manufacturers are basically located in Du Qiao and Taizhou, Fujian.

No matter whether this manufacturer or brand claims to be international or Shanghai, it is basically to register a small volume locally, entrust processing or simply brand it in the above areas.

Glasses frames are made of metal and plastic. The glasses frames used in the early days were basically copper alloys with high lead and tin contents. The cost was very low at that time. I remember that I bought an 80-cent spectacle frame (1998) in Danyang the year I first entered the business. At that time, the retail price was around 45 yuan. Because lead is very harmful to people and copper is too expensive, Monal alloy is used now, which is developed abroad. In fact, it is a copper-nickel alloy, which is not easy to rust. At first, this alloy wire was imported, and later it was copied. However, the old habit of China people is to cut corners, and the lead content still exceeds the standard. If people who wear metal-rimmed glasses don't pay attention to frequent cleaning, the heavy metals on the frames will pose a serious threat to facial skin and even whole body blood. I bet that none of the men in China who wear glasses for a long time have smooth faces.

Maybe everyone will say, I have money, I make titanium alloy, and even I want to make pure titanium.

But do you know anything about titanium? The high purity refining technology of titanium is extremely high. Only the United States, Japan and Russia in the world have titanium purification capacity close to 100%. How expensive is the real high-purity titanium? China not only has large titanium ore in Baoji, but also can only extract sponge titanium in China. Therefore, the so-called pure titanium frames you bought in the market, except for some purely imported or extremely expensive (or fake), can be asserted to be not really pure titanium.

So what impurities are there in impure titanium? Halos are radioactive elements thorium and tantalum. Although the amount is small, it is worn for a long time, which may be more important than lead in the influence on head close-range radiation.

If titanium and copper are not good, take new materials: aluminum alloy and stainless steel.

The so-called aluminum-magnesium alloy is actually aluminum alloy. You have ridden this kind of bike, haven't you? The advantage is that it is lighter and less corrosive, but the disadvantage is that aluminum is the chief culprit of Alzheimer's disease.

Stainless steel is good, but the same question, what kind of stainless steel do you use, real food grade stainless steel or industrial grade stainless steel? People who wear stainless steel frames, do you think you are wearing imported Japanese stainless steel? Are there few impurities and released elements in industrial stainless steel?

No matter how good the material is, after painting and baking, the paint layer itself will do great harm to the skin surface and long-term penetration of the body.

Therefore, I tell you responsibly that the temples should try not to use metal.

So, looking back, can temples be made of plastic (so-called plates)? In fact, you can completely make plastic nontoxic, but I don't know if you are using nontoxic plastic.

Now it seems that bamboo or sandalwood may be more environmentally friendly and healthy, but it is easy to change color and crack when worn for a short time.

There are also calf leather or salmon bag temples on the market, which are not only expensive, but also do not absorb sweat, dissipate heat or slip.

A friend said I had money, so I used tortoise shells. Don't be silly. This South China Sea turtle is not only endangered, but also a national second-class protected animal. If JS insists that this is true, you can directly report him for poaching and selling wildlife under state protection. The country should give you much more bonus than that fake mirror.

Of course, they are made of platinum and covered with gold. Sinking, spending money to find guilt, is the favorite of China people who get rich first.

Then, isn't there a temple material that is completely harmless to the human body and can completely meet the needs of cheap, lightweight, tough, unbreakable and convenient for mass production? The truth is that you can't have both. You can only choose according to your own consumption level.

Generally speaking, plate and frame are divided into two categories: light plastic injection molding and hard plastic plate cutting molding. The wholesale price of the former (the price I took out) is about 3 to 10 yuan, and the wholesale price of the latter is about 15 to 50 yuan. This refers to the mainstream style, and the old models that are thrown out may be cheaper.

The wholesale price of metal Monar alloy frames ranges from 4 yuan to 30 yuan, stainless steel frames from 15 yuan to 50 yuan, titanium alloy frames generally from 40 yuan, and pure titanium frames from 60 to 150 yuan. Tortoise shell generally ranges 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.

Then a friend will ask why a brand sells for thousands of dollars. There is a simple reason. For the same type of sports shoes produced by the same factory, the price difference between hooked and unhooked sports shoes is at least 10 times. You are willing to spend 10 times more money, which is your own vanity choice and has nothing to do with others.

Of course, brand products have his advantage, that is, they can lead the trend. He sent the design style to the OEM factory, which dared not copy it immediately. Generally, factories will produce the same frame of their own brands within a few months, so that brand products can take the lead in the market. This is similar to the clothing market, so I dare not comment.

How's it going? Thank me. So even if you go to a big store to get glasses, don't exceed 300, which is too wasteful.
