Things you need to know when buying contact lenses
1. When buying contact lenses, you must pay attention to whether the brand has the registration certificate, production license and other relevant documents issued by the State Food and Drug Administration. The State Food and Drug Administration adopts ISO international standards to test various functions of the lens, such as the degree of damage to the cornea by the lens, the process of grinding the lens, the materials used, and the moisture content and air permeability of the lens, so choose The quality of a registered brand is generally guaranteed. In addition, all regular contact lens labels must have Chinese logos. Everyone should pay attention to distinguish
2. The degree, size, material, use time, etc. of contact lenses should all be paid attention to. Many people think that the degree of frame glasses is exactly the same as that of contact lenses, so they often buy contact lenses according to the degree of frame glasses. In fact, this is wrong, because for the same eye, there is a difference between the power of wearing contact lenses and the power of wearing frame glasses. The higher the power, the more obvious the difference.
3. The size of contact lens generally depends on the wearer. The size of the black eyeball is determined. People with larger black eyes should choose larger lenses, and those with smaller black eyes should choose smaller lenses. People who are prone to dry eyes should choose contact lenses with lower water content. Those who often work in the sun can choose lenses with UV protection. Generally, people who are allergic to allergies, employees with irregular lives, people who frequently come into contact with cosmetics, and people who are often in dusty environments are more suitable to wear disposable contact lenses.
