The lenses are exquisitely blurred. Some have only been used for a year or even a few months. When I bought it, I also told them that these lenses are wear-resistant. So why would the eyeglass online turn out like this?

The main reason is not paying attention to maintenance. If you want lenses that are not easy to wear and take longer to wear, don't step on the following points:

1. Lens cannot be cleaned with hot water or warm water, only cold water can be used for cleaning. Because the film layer on the lens is not temperature resistant, it is likely to be washed away by warm water and hot water.

2. Do not directly wipe the lenses with a tissue or eyeglasses online cloth, as there may be small dust particles on the lenses. If you dry wipe the lenses, over time there will be many scratches.

The correct cleaning method is to use ultrasonic cleaning when it is relatively dirty; when it is relatively clean, rinse the surface of the lens with clean water, and use an eye cloth clockwise (one direction) to dry the water droplets; when it is not very clean, you can use an eyeglass cleaning agent to clean the water on the lens after cleaning, and be sure to use an eye cloth clockwise (one direction) to dry the water droplets.

3. Do not place glasses behind the windshield of the car. Do not wear glasses when blowing hair (the high temperature of the hair dryer can cause the surface of the lenses to peel off). Do not take a shower with new glasses (hot water, high temperature can cause the surface of the lenses to peel off, it is best to wear old glasses or not).
