Why are discountglasses lenses so prone to smudging? Many customers come to buy glasses, and the lenses are very expensive. Just ask them, they all spent a lot of money, and some only used it for a year or even a few months. At the time of purchase, the shop owner also told them that these lenses were wear-resistant. So why did the flowers end up like this?

It's mainly because of not paying attention to maintenance. To make the lenses less prone to wear and last longer, they cannot be cleaned with hot or warm water, only with cold water. Because the film layer on the lens is not temperature resistant, it is very likely to be washed away by warm water.

The lens cannot be directly wiped dry with a tissue or eyeglass cloth, as there will be small dust particles on the lens. If the lenses are wiped dry, there will be many scratches over time.

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

Do not place glasses behind the car windshield; Do not wear glasses while blowing hair, as high temperatures in the hair dryer can cause the lens surface to peel off; Do not take a shower and wear new glasses. Hot water or high temperatures can cause the lens surface to peel off. It is best to wear old glasses or not wear them.
