We give a few examples in daily life applications to help everyone understand. For example, we can no longer live without computer products, and the screens we face every day are sometimes stained. For example, CRT monitors often have an extremely thin coating on the outermost surface of the screen. This coating is very important and extremely delicate. It is even more susceptible to damage than the sensitive surface of an LCD monitor. The most important thing about the outer screen is to protect it from damage. The glare comes from its effect. For some novice users or in places with complex public environments, the screen may even be stained with fingerprints, often oily; or liquids such as coffee may be splashed on it (the most common one is human saliva. If you don’t believe it, yourself Take a look). A common sense is that you should not use any alcohol-based cleaner on the monitor screen. It is best to use pure water and gently wipe off the stains with a soft cloth. Be careful not to use too much force to avoid physical damage. This is also a general solution.

Another example is camera lenses, as well as coated spectacle lenses, telescopes, etc. Their surfaces are also quite delicate, especially camera lenses. Stains not only directly affect the image quality, but if not handled properly, they will only cause damage to the image. The dirt will get worse and the dirt that can be wiped is limited. When such a situation occurs, it will only make you more distressed. In addition, another important aspect that needs to be paid attention to when wiping this type of surface is that you cannot use wiping products with too short fibers, otherwise the short fibers that fall off are equivalent to stains, which will also greatly affect the imaging. Usually the cheapest solution is to use a long-lint cotton and gently wipe away the stain, or use an expensive lens cloth.
