In the same way, imagine that if you wear those unreliable color films, especially when exercising, your eyes will get hot, which will lead to allergic pigment layer, which is an inevitable result.
So not all color movies are harmful to eye health.
So to sum up, color films need to be purchased carefully, and beauty needs to pay a price. However, if you can control yourself, it is not so difficult to buy products with reliable quality, beauty and health.
How to identify cosmetic contact lenses?
How to distinguish good from bad cosmetic contact lenses? Buyers often have dry eyes, bloodshot eyes, or strong foreign body sensation when wearing them. These may be the reasons for wearing it for too long, but it cannot be ruled out that it is due to the quality problems of cosmetic contact lenses. However, traditional cosmetic lenses are prone to dry eyes due to more deposits and pigments on the lens surface and poor wettability, which are mainly manifested as visual fatigue, foreign body sensation in the eyes, tears in the eyes, dryness, burning eyes and even inability to see clearly.
It is recommended to choose lenses with high oxygen permeability and short-term replacement to ensure beauty, comfort and health. Wear special instructions. Beauty contact lenses are not good or bad. The best cosmetic contact lenses are suitable for your eyes. Please pay more attention when choosing! For example, some people with dry eye are not suitable for contact lenses with high water content like cosmetic contact lenses, which is directly related to the design, technology, carrier depth, tear circulation, water content, central thickness and oxygen permeability of the lenses.
Moreover, you must choose the one that suits you. For example, if the eyes are dry, you can't choose cosmetic contact lenses with high water content to wear cosmetic contact lenses. In fact, this principle is the same as contact lenses. When choosing cosmetic contact lenses, we mainly pay attention to the quality of the lenses to see if there are cracks and chromatic aberration. It is written that the buyer finds that the two lenses are not the same color after purchase, and the wearing effect will be unsatisfactory. The above points should be noted.
Formal and necessary way:
1. Find an agent in China or register a foreign-funded company in China.
2. Apply for the Import License of Medical Devices in the State Administration of Medical Supplies (contact lenses are under the supervision of Class III medical devices due to contact with cornea)-the samples are sent to the inspection agency of the US Food and Drug Administration in Hangzhou to test various indicators, and then go through some complicated procedures.
3. Register a domestic trademark (not necessarily the same as the previous brand)
4. After obtaining the drug supervision license, it is officially imported by a domestic company with legal person status and enters China through customs declaration, and then a complete Chinese logo is printed on the outside of the product, which must indicate the license number, model, agent name and telephone number of the imported medical device. Products without Chinese logo are strictly forbidden to be sold in China (not only contact lenses, but also all imported products).
Based on the above conclusions, imported color contact lenses can be divided into three categories.
1. Authentic-Only products with Chinese logo that meet the above rules are truly authentic.
2. Controversial products-all products claim to be Korean original, Hong Kong purchasing, English logo, etc. , are not legally domestic sales allowed by the state, but smuggled goods in a gray area at most, generally not recognized by the original factory (no big company is willing to provide guarantee for smuggled goods), and there is no after-sales guarantee in China (because there is no legal agency to sell them)-it is invisible in regular optical shops in China.
3. Fake goods-because there is no legal organization to operate in China, they often become the source of fake goods (making their own Korean logo or English logo or even anti-counterfeiting labels and websites, so-called genuine goods), and a large number of individuals or small organizations sell them through the Internet or in some informal physical stores (such as lattice shops). ).
Next, I will talk about the status quo of several popular brands on the Internet.
1.GEO—— "Jiao" in Chinese has been officially registered in Chinese.
2.DUEBA- authentic, please choose one with Chinese logo, the brand is not DUEBA, the name is Le Tong, Barbie, and so on.
3.neo- authentic, Chinese logo are "Anthrazio" and "Tanya", boxed knight version, etc.
4. BESCON-authentic, Korean original packaging, authorized by China. And other transparent films. I won't introduce them one by one.
5. Aliens-there are genuine products, and most of the imitations are B 1 1 black and foreign language packages. You should know if you bought it! Other imitations are basically not produced.
Summarize the authentic logo first!
1. Chinese logo
2. Have the registration code of the Food and Drug Administration.
3. There are manufacturers
4. There is a production date or expiration date.
All four are finished! The party is the real thing on the mainland!
