Question 2: What is the classification of contact lenses on Taobao? They belong to accessories. In fact, you can directly search for "contact lenses" in the search bar.
Question 3: Taobao sells contact lenses, which category should it be placed in? Wash and protect the products, and then don't mention the key words of contact lenses in the content. I saw that Taobao sells contact lenses and they are very popular, but there is no key word "contact lenses" in it.
Question 4: Ask for help. What category should Taobao choose to sell contact lens boxes? It's wrong to change it for half a day, and there is still no sales attribute. Under the category of glasses accessories, there are lens cloth, lens bag and lens box options. You can choose that.
Question 5: What are the national and industrial standards for contact lenses? Contact lens industry standard list.
1, the glasses industry standard stipulates that optometry shops must have an independent optometry area, and optometry should meet the sight distance of 5 meters (or more). The light in the optometry area should be soft and moderate to avoid dim light or glare. The Code also puts forward strict requirements for the qualification of optometrists. Contact lens optometrists should hold intermediate or above professional qualification certificates for optometry.
2. The contact lens industry standard stipulates that when choosing lenses, we must pay attention to whether a brand has a registration certificate issued by the US Food and Drug Administration. The US Food and Drug Administration adopts iso international standards.
Accurately test the functions of the lens, such as the damage degree of the lens to the cornea, the polishing process of the lens, the materials used, the water content and air permeability of the lens, etc. Therefore, the quality of a brand with a registration certificate is generally guaranteed.
3. Pay attention to the degree, size, material and service time of the lens. Many people think that the degree of frame glasses and contact lenses is exactly the same, so they often buy contact lenses according to the degree of frame glasses.
Glasses. In fact, this is wrong, because for the same eye, the degree of contact lenses and frame glasses is different. The higher the degree, the more obvious the difference. Generally, there is little difference between lenses below 400 degrees.
More than 400 degrees, need to add and subtract degrees. Contact lenses used to correct myopia are lower than frame glasses. For example, the result of optometry is 450 degrees myopia, and contact lenses need to be reduced by 25 degrees, just need to be matched.
425 degrees will do. The contact lens used to correct hyperopia has a high degree. For example, the optometry result is 450 degrees hyperopia, and the contact lens needs to be increased by 25 degrees and matched with 475 degrees.
4. The contact lens industry standard stipulates that the size of the lens is generally determined according to the size of the wearer's black eyeball. People with larger black eyeballs should choose larger lenses, and people with smaller black eyeballs should choose them.
A smaller lens. People who are prone to dry eye should choose contact lenses with low water content. People who often work in the sun can choose lenses with anti-ultraviolet function. Generally allergic people, often contact.
People with cosmetics and people who are often in dusty environments are more suitable to wear disposable contact lenses.
Question 6: The types of contact lenses are hard contact lenses (RGP), soft contact lenses and breathable contact lenses. Rigid contact lenses are generally made of PMMA polymer, while rigid gas permeable (RGP) contact lenses (RGP) are more popular. Czechoslovakian chemist Otto Welch Tarla invented soft contact lenses in 1960. Because they are comfortable to wear, they have become the most popular types of lenses today. Breathable glasses are made of hydrophilic materials, allowing oxygen to enter the cornea through the lens, which is more comfortable to wear. ⑴ Daily wearing means that the wearer wears the lens without sleeping or opening his eyes, usually one day 12 hours. (2) Elastic wearing refers to taking a nap with glasses or occasionally wearing glasses for the night, no more than 2 nights a week (discontinuous). (3) Long wear means that the wearer still wears the lens when sleeping and takes it off for a few days. (4) Night contact lenses refer to wearing glasses when sleeping at night and taking them off when getting up in the morning. This kind of hard contact lens worn at night is also called orthokeratology. Experts pointed out that according to the way of wearing, it can be divided into long wearing type, daily wearing type and night wearing type. According to the length of the lens service cycle, it can be divided into three types: disposable type, regular replacement type and traditional type. The time for the first wearer can be increased by 4 hours, 6 hours and 8 hours, and the time can be extended after slowly adapting. ⑴ Vision correction lenses: used for patients with ametropia, aphakia or keratoconus. 1. spherical mirror: used for eyes with no astigmatism or low astigmatism. 2.
