Mistakes in maintaining lenses
1. Wipe the lens repeatedly
Many people have a habit of pulling up the corners of their clothes when they find their glasses dirty, or wipe them with paper towel when they see some scratches on the lenses. These are all wrong behaviors. In fact, most of the scratches on the lens are caused by this improper behavior. We should wash the glasses with water, and then rub them gently with detergent. We can't rub them repeatedly. We need to clean them in the same direction. Finally, dry them naturally or wipe them gently with glasses cloth.
2. Wipe the lens directly with glasses cloth
In fact, the so-called cloth used to wipe the glasses can not be changed into glasses directly. Because there are a lot of tiny dust particles on the lens, directly dry rubbing with glasses cloth is just like using sandpaper to scratch the lens. As time goes by, the lens will become blurred, so the glasses cloth is not used to wipe glasses directly. If the lens is dirty or greasy, wash it with tap water or use some detergent. After rinsing with clean water, gently dry the water with napkin or wipe it with mirror cloth. In this way, the lens washed out is clean and will not damage the film layer.
3. The glasses case is hardly used
Many people are equipped with glasses, directly put the glasses box in a corner idle. In fact, glasses should be wrapped with glasses cloth when they are not in use. The hard lens box can prevent glasses from being crushed and broken. Don't touch the lens directly with your hands to avoid friction and oil and sweat stains.
4. The glasses don't need to be changed if they are not damaged
Many people's definition of changing glasses is to replace them only when they are broken. Even if the lenses have been scratched, stained, cracked, and peeling off, they are still making do with it. In this case, it is recommended to replace the glasses as soon as possible. Because the scattering of light may lead to blurred vision, which can cause vision loss over time.
