First, the production cost of contact lens liquid is the lowest, and the overall profit is the largest. The production cost is basically the price of packaging, and the liquid inside may not be much more expensive than normal saline. Have you seen a bottle of normal saline in 4 yuan? Due to the restrictions on drug import, there is no possibility that you can 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. If you really want to protect your eyes, don't use contact lenses.
incidentally, comfort liquid, that is, artificial tears, has basically the same functions and components except the all-around product.
Second, contact lenses can be divided into hard and soft lenses. Hard contact lenses do the least harm to glasses, but the cost of fitting, maintenance and maintenance 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, to 8, yuan, and the price of incoming goods is around 1,5 yuan in 1 yuan. Because of the monopoly system, the channels for obtaining goods are narrow. But as far as I know, there should be many smuggled parallel imports.
if a small shop sells you so-called Korean goods, the quality of this kind of goods is ok. You can try it, but it is unstable, because it may be made by Haichang factory this month and Weikang factory next month. When you sell it, you must see 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 6 to 9, and you don't have to pay for it.
III. Glasses
Glasses are divided into two types: glass and resin. The wholesale price of ordinary white glass is generally around one pair in 1 yuan, and the coated glass is in 5 yuan. Now, due to the decrease in production, the price of some glasses has been slightly raised, so it should be in 15 yuan. The price of some high-grade glass lenses, such as 1.9 refractive index, is still very high, but few are made in China and are generally imported.
So, isn't there a kind of temple material that is completely harmless to human body and can fully satisfy the requirements of being cheap, light, tough, non-fragile and convenient for mass production? The fact is that you can't have both. You can only choose according to your own consumption level.
Generally speaking, plate frames are divided into two categories: light plastic injection molding and hard plastic plate cutting molding. The wholesale price of the former (the price I take out) is about 3 to 1 yuan, while the wholesale price of the latter is about 15 to 5 yuan. This refers to the mainstream style, and the old models that are dumped may be cheaper.
the wholesale price of metal monal alloy frames ranges from 4 yuan to 3 yuan, stainless steel frames range from 15 yuan to 5 yuan, titanium alloy frames generally range from 4 yuan to, and pure titanium frames range from 6 to 15 yuan. Tortoise shells generally range from 3 yuan to 8 yuan. The above prices will vary depending on the brand and origin, style and weight, but the production cost is basically the same.
Then 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, the price difference between those with and without hooks is at least 1 times. You are willing to spend 1 times more money, which is your own vanity choice and has nothing to do with others.
Of course, branded products have his advantage, that is, they can lead the trend. He sends the design style to the OEM factory, which is afraid to copy it immediately. Generally, the factory will produce the same frame of its own brand in a few months, so that branded products can completely take the lead in the market. This is similar to the clothing market, and I dare not comment.
so even if you go to a big store to get glasses, don't exceed 3, which is a waste.
